Description

  The present invention relates to an electronic device or the like provided with a display device having a display unit and a means for detecting an indicated position on the display unit.

  There is known an electronic apparatus including a display device having a display (display unit) and a touch panel that detects a touch position (instructed position) on the display. In such a device, an input operation can be performed by a touch operation (instruction operation) on the display. For example, a bank ATM or a ticket machine at a station performs a touch operation by touching a button displayed on the display with a finger, and an electronic device such as a PDA or a word processor uses a stylus pen attached. Perform the operation. In particular, an electronic device such as a PDA or a word processor that can input handwritten characters can express a change in the thickness of the line of the input characters. Specifically, for example, by gradually expanding the display point range depending on the pressing time, for example, slowly It is known that a thick line is drawn and displayed in the handwriting operation described above, and a thin line is drawn and displayed in a fast handwriting operation (for example, Patent Document 1).

JP 7-114345 A

  In the input control by the touch operation, it is recognized that the touched position on the display (more precisely, the position detected as touched by the touch panel) is input. For this reason, in a portable electronic device such as a PDA having a relatively small display, a touch operation is often performed using a dedicated stylus pen that can reliably indicate one point on the display. Also, in portable electronic devices, for example, the device is often held with one hand and the stylus pen is held with the other hand, but in this case, the device is likely to become unstable. Touch operations may not be performed.

  For this reason, for example, when a display object (button or the like) on the display is selected by touching, it is necessary to accurately touch the desired display object, but the display object is small or the posture of the device being held is The desired display object may not be accurately touched for reasons such as being unstable. Furthermore, when a touch operation is performed with a finger, the area (contact area) where the finger contacts the display is larger than that of the stylus pen, so other display objects in the vicinity of the desired display object are erroneously displayed. If selected, unintended input may occur.

  In addition, for example, when inputting a locus such as handwritten character input, the locus of the touch operation is recognized as the input locus, but the touch operation is shaken because the device or the hand performing the touch operation tends to become unstable. A smooth trajectory may not be input. Furthermore, when a touch operation is performed with a finger, the contact area between the finger and the display is large, and thus there is a problem that the input locus becomes thick.

  In view of the above circumstances, the present invention provides a new input different from conventional input control in which only an actually designated position is recognized in an electronic device that performs an operation input by an instruction operation on a display unit. The purpose is to realize control.

  According to the sixth aspect, the same effect as in any one of the first to fifth aspects is obtained, and even if the same designated position is not detected, the same for the predetermined surplus time. Assuming that the indicated position is detected, the control of the change in the size of the input range and the identification display of the input range can be continued.

  According to the eighth aspect, the same effect as in any one of the first to seventh aspects is obtained, and the same is applied when the designated position is detected in a predetermined range that can be regarded as the same designated position. It can be determined that the designated position is continuously detected. In other words, if the change in the indicated position is within a predetermined range, it is regarded as an instruction to the same position. For this reason, the user cannot perform an accurate instruction operation, for example, the indicated position fluctuates when the device is unstable. Even in such a case, it is possible to continue the instruction to the same position without worrying much about the fluctuation of the indicated position.

The ninth form is the program of the eighth form,
The same position determining means is
Representative position determination means (for example, FIG. 11) that determines a representative position representing the indicated position detected within the unit time based on a plurality of indicated positions detected within the unit time for each predetermined unit time.

  According to the ninth aspect, the same effect as in the eighth aspect is obtained, and the representative position is determined based on a plurality of designated positions detected within the unit time for each predetermined unit time. Whether or not the same designated position is continuously detected can be determined depending on whether or not the representative position has changed within a predetermined range. That is, for example, when the same position is continuously indicated with a finger, the detected indicated position fluctuates in the contact portion between the finger and the display unit, and the representative position based on the fluctuating designated position is also the corresponding contact It will almost fluctuate inside. Therefore, for example, even when instructed (touched) with a stylus pen that designates one point or when instructed (touched) with a finger whose contact portion is a “surface”, it is almost surely moved to the same position. It is possible to determine whether to continue the instruction.

The tenth form is

It is also possible to configure an electronic device characterized by comprising:

  According to the tenth embodiment and the like, when the locus input control by the sliding operation is performed based on the detected indication position on the display unit, a plurality of units detected within the unit time are detected every predetermined unit time. By determining a representative position based on the designated position and performing a predetermined interpolation process based on the representative position for each determined unit time, it is possible to determine the input locus by the sliding operation. That is, instead of determining the detected individual pointing positions themselves as input loci, the input trajectory by the sliding operation is determined by performing a predetermined interpolation process based on the representative positions representing these pointing positions. New input control can be realized. Therefore, when an accurate trajectory input is not required as much as the detection accuracy of the indicated position on the display unit to be detected, it is possible to control the trajectory input with reduced (decreased) detection accuracy.

The game score can be calculated based on the determination result of the intersection determination between the game object and the character by moving and displaying on the display unit. Therefore, the user can enjoy a game in which, for example, the character is moved by a sliding operation so as to cross / do not cross the game object.

The twelfth form is a program according to any one of the ninth to eleventh forms,

  According to the twelfth aspect, the same effect as any one of the ninth to eleventh aspects is obtained, and the number of designated positions serving as a reference for determining the representative position is changed by changing the unit time. Can do. That is, as the unit time is shorter, the number of designated positions serving as a reference for determining the representative position is smaller, so that the determined input locus is closer to the detected designated position locus itself, while the unit time is longer. As the number of designated positions serving as a reference for determining the representative position increases, the determined input locus becomes a smoother locus. That is, by changing the unit time, it is possible to adjust how much the input trajectory is determined (decreased) from the detection accuracy of the indicated position on the display unit to be detected.

The thirteenth form is a program according to any one of the ninth to twelfth forms,
The representative position determining means is a program for causing the computer to function so as to determine an average position of a plurality of designated positions detected within the unit time as a representative position.

  According to the thirteenth aspect, the same effects as in any of the ninth to twelfth aspects can be obtained, and the average position of the plurality of designated positions detected within the unit time can be determined as the representative position. That is, it is possible to determine a trajectory that passes through substantially the center of the distribution range of the designated position detected during the sliding operation as the input trajectory.

  Here, the “information storage medium” refers to a hard disk, an MO, a CD-ROM, a DVD, a memory card, an IC memory, or the like that can read stored information. Therefore, according to the fourteenth aspect, by causing the computer to read the information stored in the information storage medium and executing the arithmetic processing, the same effect as any one of the first to thirteenth aspects is achieved. be able to.

  The best mode for carrying out the present invention will be described below with reference to the drawings. In the following, the case where the present invention is applied to a portable game device which is a kind of electronic apparatus will be described, but the application of the present invention is not limited thereto.

[appearance]
FIG. 1A is an external view showing an example of a portable game apparatus 1 to which the present invention is applied. According to FIG. 1, the game apparatus 1 includes a display 3, an operation key 5 including a cross key 5a and a function key 5b, and a speaker 7 on a front surface of a substantially rectangular parallelepiped housing. Although not shown, a power switch for turning on / off the power of the game apparatus 1, a volume switch for adjusting the output sound of the speaker 7, a memory card as an external storage medium of the game apparatus 1, A card slot for detachably mounting an IC card or the like, a cable connector for connecting a communication cable for communicating with an external device such as another game device, and the like are provided.

  The display 3 is a color liquid crystal display such as a TFT (Thin Film Transistor). In addition, as shown in FIG. 2B, the touch panel 4 is integrally formed on the upper surface (or lower surface) of the display 3. The touch panel 4 detects the touched position on the display 3 by a detection method such as pressure-sensitive type, optical type, electrostatic type, electromagnetic induction type, etc., for example, in units of dots constituting the display 3, and detects the detected position (hereinafter, (Referred to as “touch position”) P signal (touch operation signal) is output. The touch position P is expressed in the XY coordinate system set on the touch panel 4. The player can perform various operation inputs by a touch operation on the display 3 using the attached stylus pen 9 or a finger.

  In addition, a control unit equipped with a CPU, an IC memory, and the like is built in the housing. The CPU executes various game processes based on the program and data read from the IC memory and the like, the operation signal input from the operation key 5, the touch operation signal input from the touch panel 4, and the like. A sound signal of the game sound is generated. Then, the generated image signal is output to the display 3 to display the game screen, and the generated sound signal is output to the speaker 7 to output the game sound.

  Information necessary for the game apparatus 1 to execute the game (system program, game program, game data, etc.) is stored in an IC memory mounted on a control unit in the housing or externally detachable from the game apparatus 1. It is stored in a memory card or IC card as a storage medium.

  By the way, the touch panel 4 has (1) “one point detection type” capable of detecting only one point at the same time, and (2) “multiple point detection type” capable of detecting a plurality of points simultaneously. is there.

  FIG. 2 is a diagram illustrating a touch position P detected when the display 3 is “one-point detection type”. In this case, when a touch operation is performed using the stylus pen 9, the position where the pen tip abuts (contacts) the display 3 is detected as the touch position P as shown in FIG.

  Further, when a touch operation is performed using a finger, as shown in FIG. 5B, a certain point in the portion (contact portion) TA where the fingertip (specifically, the belly of the finger) contacts the display is It is detected as the touch position P. At this time, since the contact portion TA is a “surface” having a certain size, the detected touch position P fluctuates in the contact portion TA with time as shown in FIG. It is not fixed to one point.

  FIG. 3 is a diagram for explaining a touch position P detected when the display is a “multiple-point detection type”. In this case, when a touch operation is performed using the stylus pen 9, the position where the pen tip contacts the display 3 is detected as the touch position P as shown in FIG. That is, the touch position P detected is only one point, which is the same as in the “one-point detection type”.

Further, when a touch operation is performed using a finger, each point constituting the contact portion TA between the finger and the display 3 is detected as a touch position P as shown in FIG. That is, a plurality of touch positions P _i (i = 1, 2,...) Are detected. The number i of detected touch positions P depends on the resolution of the touch panel 4 and the size (area) of the contact portion TA, and the higher the resolution, or the larger the size of the contact portion TA. The more it increases.

  In the game apparatus 1, one or a plurality of touch positions P detected by the touch panel 4 are acquired every predetermined time (for example, every frame), and touch operation input control is performed based on the acquired touch positions P. The This embodiment is characterized by this touch operation input control.

[First Embodiment]
First, the first embodiment will be described.
In the first embodiment, the input range is set based on the touch position P detected by the touch panel 4 and the input range is changed according to the time during which the detection of the same touch position P is continued (detection duration time). Is. Here, the input range is a range on the display 3 in which the range within the game device 1 is regarded as an input by a touch operation (may be “point (1 dot)”).

<Overview>
4 and 5 are diagrams for explaining the outline of the first embodiment. As shown in FIG. 4A, when the display 3 is touched with the stylus pen 9 (start of touch operation), the touched position, that is, the position where the pen tip is in contact is detected as the touch position P. The detected touch position P is set as the input range IA, and the input range IA is identified and displayed. That is, the input range IA is the touch position P itself, which is a “point”.

  Then, when a predetermined time elapses while the same position is touched (while the stylus pen 9 is stationary), the input range IA that is a “point” changes the touch position P as shown in FIG. It changes to a circular “region” with a center. Thereafter, when the same position is further touched, the input range IA gradually expands concentrically with the touch position P as the center as time passes, as shown in FIG. In the figure, the identification display of the input range IA is represented by diagonal lines, and the same applies to each figure described later.

  Further, as shown in FIG. 5A, when the input range IA, which is a circular “area”, is set, when the display 3 is moved on the display 3 with the stylus pen 9 in contact (sliding) Touch operation), as shown in FIG. 5B, the setting of the circular input range IA is canceled and the identification display is erased. While the stylus pen 9 is moving, the touch position P detected at any time is set as the input range IA, and the set input range IA is identified and displayed. That is, the input range IA changes from “region” to “point”.

  Then, after the stylus pen 9 is made stationary, when the predetermined time elapses again with the stylus pen kept stationary, the input range IA has a circular shape centered on the position (touch position P ′) where the pen tip is in contact at that time. This “region” changes to a concentric circle around the touch position P ′ as time passes. Thereafter, when the stylus pen 9 is released from the display (end of the touch operation), the setting of the input range IA is ended and the identification display of the input range IA is erased.

  4 and 5 show the case where the touch operation is performed using the stylus pen 9, the same applies to the case where a finger is used. That is, when a certain point on the display 3 is continuously touched with a finger, after a predetermined time has elapsed, the input range which is a “point” is centered on a certain point in the contact portion between the finger and the display 3. It changes to a circular “region” and gradually expands concentrically over time. Then, when the finger is moved on the touch panel 4 with the finger in contact (sliding touch operation), the input range changes to “point” again, and when the finger is moved away from the touch panel 4 (end of touch operation), The input range setting is completed and the input range identification display is erased.

  As described above, in the first embodiment, the input range IA initially set as a “point” is changed to a circular “region” by a touch operation of continuously touching the same position on the display 3, and this input is performed. The range IA changes so as to gradually expand with time.

<Principle>
FIG. 6 is a diagram for explaining the principle of input range setting in the first embodiment. This figure shows the relationship between the touch position P and the setting of the input range IA acquired when a touch operation is performed such that the horizontal axis is time t and the same position on the display 3 is continuously touched.

即ち、代表位置Ｑはタッチ位置Ｐ₁、Ｐ₂、・・、Ｐ_jの平均位置である。 As shown in the figure, in the first embodiment, while a touch operation is being performed, a plurality of touch positions P ₁ , P detected during the detection unit time Δt for each predetermined detection unit time Δt. ₂ ,..., A representative position Q (xq, yq) representing P _j is calculated according to the following equation (1).

That is, the representative position Q is the touch position P _1, P _2, · ·, the average position of P _j.

  Here, as will be described later, the detection unit time Δt corresponds to a time interval for determining whether or not the same touch position P is detected, and is set as a time of, for example, several tens to ten frames. Therefore, during this detection unit time Δt, for example, when the touch position P is acquired for each frame, at least the touch position P of the number of frames F corresponding to the detection unit time Δt is acquired. .

Then, based on these average positions Q ₁ , Q ₂ ,... Calculated every detection unit time Δt, it is determined whether or not the same touch position P is continuously detected. Specifically, first, it is determined whether or not the same touch position P is detected at the representative position Q ₀ calculated at the time t ₁ when the detection unit time Δt has elapsed from the time t ₀ when the touch operation is started. The reference position R is set as a reference. Next, it is determined whether each of the representative positions Q ₁ , Q ₂ ,... Calculated each time the detection unit time Δt elapses coincides with the reference position R in order, so that the same touch is performed. It is determined whether or not the position P has been detected.

Here, whether or not the representative position Q and the reference position R coincide with each other depends on the distance L (see FIG. 7) between the representative position Q (Q ₁ and Q ₂ in the figure) and the reference position R. The determination is made based on L1, L2) in the figure. That is, if the distance L is equal to or less than the predetermined determination reference distance Lb, it is determined as “match”, and if not, it is determined as “not match”. In the figure, the distance L1 between the representative position Q _1, the reference position R is smaller than the determination reference distance Lb, representative positions Q ₁ is and the reference position R is determined to be "matching". The distance L2 between the representative position Q ₂ and the reference position R because greater determination reference distance Lb, the representative position Q ₂ is and the reference position R is determined to be "not identical". If it is determined that the representative position Q and the reference position R are “matched”, it is determined that the same touch position P is detected, and if it is determined that “does not match”, the same touch position P is detected. It is judged that it is not done.

  The determination reference distance Lb is determined as follows. That is, when a static touch operation is performed using the stylus pen 9, the detected touch positions P are substantially the same as shown in FIG. 2, and the representative position Q calculated from these touch positions P is shown. Are also almost identical.

  On the other hand, when a touch operation is performed using a finger, as shown in FIG. 3, the detected touch position P is not fixed at one point, and fluctuates within the contact portion TA between the finger and the display 3. . Therefore, the average position Q calculated from these fluctuating touch positions P also varies within the contact portion TA and is not fixed at one point, as shown in FIG. 8A. That is, if the representative position Q fluctuates within the contact portion TA, it can be regarded that a touch operation is performed on substantially the same position, that is, the same touch position P is detected.

  For this reason, as shown in FIG. 5B, when it is assumed that the reference position R is located substantially in the center of the contact portion TA, the representative position Q that fluctuates in the contact portion TA is the reference position R and “ It is determined based on the size of the abdominal surface of a typical human finger so that the contact portion TA is substantially within the circle centered on the reference position R and having a radius of Lb. A determination reference distance Lb is determined.

As a result of determining whether or not each of the representative positions Q ₁ , Q ₂ ,... Matches the reference position R, the number of times determined as “matching”, that is, the same touch position P is detected. The representative position Q calculated every unit detection time Δt is within the input range while the number of consecutively determined times (hereinafter referred to as “continuous detection number”) n is less than the predetermined change start number N. Set as IA. That is, the input range IA during this period is a “point”.

  When the continuous detection number n reaches the change start number N, the change of the input range IA is started. That is, the same touch position P continues for a time corresponding to the product of the detection unit time Δt and the number N of change start times (hereinafter referred to as “input range change start time”) Ts (= Δt × N). Then, the change of the input range IA is started.

FIG. 9 is a diagram illustrating the change of the input range IA. As shown in the figure, first, the representative position Q (representative position Q _{N in} FIG. 6) at the time when the continuous detection number n reaches the change start number N is set as the center position O, and a predetermined radius change amount Δr (however, , Δr> 0), a circular “region” having a radius r is set as the input range IA. Thereafter, every time the detection unit time Δt elapses, the radius r of the input range IA is increased by the radius change amount Δr. That is, the input range IA during this period is an “area”, and gradually expands concentrically with the center position O as the center over time.

Thereafter, when it is determined that the representative position Q _O and the reference position R do not match at time t _O , that is, it is determined that the same touch position P is not detected, the change of the input range IA is ended. The representative position Q _O is set as the input range IA. That is, the input range IA changes to “point” again. Then, the representative position Q _O is reset as a new reference position R, and thereafter the same processing is repeated.

  Next, a specific application example using the above-described principle will be described.

<Application example 1>
In application example 1, the principle described above is applied to the icon selection screen. The icon selection screen is a screen that displays a plurality of icon buttons as player options. For example, before or during the start of the game, such as selecting a character that forms a team, selecting weapons or armor equipped with the character, etc. , Displayed as needed.

(Overview)
FIG. 10 is a diagram illustrating an outline of the application example 1 and illustrates an example of an icon selection screen displayed on the display 3. According to the figure, a plurality of icon buttons IB1, IB2, IB3 are displayed on the icon selection screen. The player inputs a selection operation of a desired icon button IB by a touch operation.

  For example, when the display 3 is touched with the stylus pen 9, the position where the pen tip abuts is detected as the touch position P as shown in FIG. 5A, and the detected touch position P is set as the input range IA. The The icon buttons IB that are partly or entirely included in the input range IA are in the “selected state”. In FIG. 5A, the icon buttons IB1 and IB2 are present in the input range IA (that is, the touch position P itself). , IB3 is not included. Accordingly, none of the icon buttons IB1, IB2, and IB3 is in the “selected state”.

  Next, when a predetermined time (specifically, the input range change start time Ts) elapses with the same position being touched, the input range IA changes to a circular “region” having the touch position P as the center position O. After that, it gradually expands concentrically with time. When the input range IA expands to include a part of the icon button IB1 (the right side portion in the figure) as shown in FIG. 5B, the icon button IB1 becomes “selected” and “selected”. It is highlighted (inverted display) to indicate that it is.

  Further, when the input range IA further expands and the input range IA includes a part of the icon button IB2 (right side portion in the same figure) as shown in FIG. "Is highlighted (inverted display).

  Thereafter, when the stylus pen 9 is released from the display 3 (end of the touch operation), it is determined that the icon button IB selected at that time is selected. For example, when the touch operation is terminated in the state shown in FIG. 5C, the selection of the icon buttons IB1 and IB2 is confirmed.

  In addition, although FIG. 10 demonstrated the case where touch operation was performed using the stylus pen 9, it is the same also when touch operation is performed using a finger. That is, if the same position on the icon selection screen is continuously touched, after a predetermined time (specifically, input range change start time Ts) has elapsed, the input range IA is within the contact portion between the finger and the display 3. It changes to a circular “region” having a certain point as the center position O, and gradually expands with time. Then, the icon button IB that includes part or all of the input range IA is in the “selected state”, and when the finger is released from the display 3 (end of the touch operation), the icon that is in the “selected state” at that time The selection of button IB is confirmed.

(Functional configuration)
FIG. 11 is a block diagram illustrating a functional configuration of the game apparatus 1 in Application Example 1. As illustrated in FIG. As shown in the figure, in application example 1, the game apparatus 1 functionally includes an operation input unit 10, a processing unit 20, an image display unit 30, a sound output unit 40, a storage unit 50, It is configured with.

  The operation input unit 10 receives an operation instruction from the player and outputs an operation signal corresponding to the operation to the processing unit 20. This function is realized by, for example, a button switch, lever, dial, mouse, keyboard, various sensors, and the like. The operation input unit 10 includes the touch panel 4 and outputs the touch position P detected by the touch panel 4 to the processing unit 20.

  The processing unit 20 performs various arithmetic processes such as control of the entire game apparatus 1, game progress, and image generation. This function is realized by, for example, an arithmetic device such as a CPU (CISC type, RISC type), ASIC (gate array, etc.) or a control program thereof. In FIG. 1, the CPU mounted on the control unit built in the game apparatus 1 corresponds to this.

  The processing unit 20 includes a game calculation unit 210 that mainly performs calculation processing related to the game, and a game image and a game image for displaying a game screen based on various data obtained by the processing of the game calculation unit 210. An image generation unit 230 that generates an image signal for displaying the sound, and a sound generation unit 240 that generates a sound signal for outputting a game sound such as a sound effect and BGM and a game sound.

  The game calculation unit 210 executes various game processes based on operation signals and touch operation signals input from the operation input unit 10, game information (program and data) read from the storage unit 50, and the like. In application example 1, the game calculation unit 210 includes an input range setting unit 212A, an input range display control unit 214, and an icon selection unit 216.

  Based on the touch operation signal input from the operation input unit 10, the input range setting unit 212A sets the input range IA according to the input range setting reference data 522A.

  The input range setting reference data 522A sets a reference value (input range setting reference value) when the input range is set by the input range setting unit 212A. FIG. 12 shows an example of the data configuration of the input range setting reference data 522A. According to the figure, the input range setting reference data 522A includes a detection unit time (522A-1), a change start count (522A-2), a determination reference distance (522A-3), and a radius change amount (522A- 4) and are stored. The input range setting reference data 522A is fixed data that is not changed through the progress of processing, but may be changed according to, for example, a setting input by a player.

The detection unit time (522A-1) sets the value of the detection unit time Δt.
The change start count (522A-2) sets the value of the change start count N. When the continuous detection count n reaches the change start count N, the change of the input range IA is started. That is, the product (Δt × N) of the number N of change start times and the detection unit time Δt is the input change start time Ts for starting the change of the input range IA.

  The determination reference distance (522A-3) sets the value of the determination reference distance Lb. If the distance L between the representative position Q and the reference position R is equal to or less than the determination reference distance Lb, the representative position Q and the reference position R are determined to be “match”, and otherwise “not match”. It is determined.

  The radius change amount (522A-4) sets the value of the radius change amount Δr. When the input range IA is enlarged and changed, the radius r of the input range IA is increased by this radius change amount Δr for each change.

  The input range setting unit 212A calculates the representative position Q from the plurality of touch positions P acquired during the detection unit time Δt each time the detection unit time Δt elapses, and calculates the representative position Q and the reference It is determined whether or not the same touch position P is detected by determining whether or not the position R matches. Then, while the number of times that the same touch position P has been detected (the number of times of continuous detection) n does not reach the number N of change start times, the setting is updated with the calculated representative position Q as the input range IA. When the detection count n becomes equal to or greater than the change start count N, every time the detection unit time Δt elapses, the input range IA is changed by increasing the radius r of the input range IA by the radius change amount Δr.

  Each data acquired / calculated by the input range setting unit 212 </ b> A is stored in the input range setting data 524. FIG. 13 shows an example of the data configuration of the input range setting data 524. According to the figure, the input range setting data 524 includes the acquired touch position data 524a, the representative position (524b), the reference position (524c), the number of consecutive detections (524d), and the input range (524e). Store.

  The acquired touch position data 524a stores coordinate values of a plurality of touch positions P acquired during the detection unit time Δt. When the touch position P detected by the touch panel 4 is acquired, the acquired touch position P is accumulated in the acquired touch position data 524a. The acquired touch position data 524a is cleared every time the detection unit time Δt has elapsed and the representative position Q is calculated.

  The representative position (524b) stores the coordinate value of the representative position Q calculated from the plurality of touch positions P accumulated in the acquired touch position data 524a. The representative position (524b) is updated to the calculated representative position Q every time the detection unit time Δt elapses and the representative position Q is calculated.

  The reference position (524c) stores the coordinate value of the reference position R. When it is determined that the representative position Q and the reference position R do not coincide with each other, the reference position (524c) is updated by setting the representative position Q as a new reference position R.

  The continuous detection count (524d) stores the value of the continuous detection count n. When the representative position Q and the reference position R are determined to “match”, the number of consecutive detections (524d) is updated to a value obtained by adding “1” to the current value, and is determined to be “not matched”. Then, the initial value is updated to “0”. That is, the product (n × Δt) of the number of consecutive detections n and the detection unit time Δt corresponds to the time during which the detection of the same touch position P is continued (detection continuation time).

  The input range (524e) stores data indicating the input range IA currently set. Specifically, if the input range IA is “point”, the coordinate value of the position of this “point” is stored. If the input range IA is a circular “area”, the coordinate value and radius of the center position O of the circle are stored. Stores the value of r.

  In FIG. 11, the input range display control unit 214 performs control to identify and display an area in the image display unit 30 corresponding to the input range IA set by the input range setting unit 212A.

  Based on the icon data 526, the icon selection unit 216 displays an icon selection screen displaying a plurality of icon buttons on the image display unit 30 as shown in FIG. 10, for example.

  The icon data 526 stores data related to the icon button IB to be displayed on the icon selection screen. FIG. 14 shows an example of the data configuration of icon data 526. According to the figure, the icon data 526 includes, for each icon ID (526a) for identifying each icon button IB, image data (526b) representing the icon button IB, a display position (526c), and a selection state (526d). ) And are stored in association with each other.

  The display position (526c) stores data specifying the display position (specifically, the display range) of the image data (526b) in the icon selection screen. Specifically, for example, coordinate values in the image display unit 30 corresponding to two points (for example, upper left vertex and lower right vertex) of image data are stored.

  The selection state (526d) stores data indicating whether or not the icon button IB is in the “selection state”. Specifically, the initial value is “unselected state”, and when the input range IA set by the input range setting unit 212A is partially or entirely included, the “selected state” is set. When the touch operation ends, the icon button IB that is in the “selected state” at that time is determined as being selected by the touch operation.

  When the icon selection screen is displayed, the icon selection unit 216 determines whether or not each icon button IB is partly or entirely included in the input range IA set by the input range setting unit 212A. The icon button IB determined to be “selected”. When the end of the touch operation is detected, the selection of the icon button IB that is in the “selected state” at that time is confirmed.

  The image generation unit 230 generates a game image for displaying a game screen by executing geometric transformation, shading processing, and the like based on the calculation result of the game calculation unit 210, and the image display unit 30 displays the image signal of the generated image. Output to.

  Based on the image signal from the image generation unit 230, the image display unit 30 displays the game screen while redrawing an image of one frame every 1/60 seconds, for example. This function is realized by hardware such as CRT, LCD, ELD, PDP, and HMD. In FIG. 1, the display 3 corresponds to this.

  The sound generation unit 240 generates game sounds such as sound effects and BGM used during the game, and outputs the generated game sound signal to the sound output unit 40.

  The sound output unit 40 outputs game sounds such as BGM and sound effects based on the sound signal from the sound generation unit 240. This function is realized by a speaker or the like, for example, and the speaker 7 corresponds to this in FIG.

  The storage unit 50 stores a system program for realizing various functions for causing the processing unit 20 to control the game apparatus 1 in an integrated manner, a program and data necessary for executing the game, and the like. 20 is used as a work area, and temporarily stores calculation results executed by the processing unit 20 according to various programs, input data input from the operation input unit 10, and the like. This function is realized by, for example, various IC memories, hard disks, CD-ROMs, DVDs, MOs, RAMs, VRAMs, and the like. In FIG. 1, this corresponds to an IC memory mounted on a control unit built in the game apparatus 1 and an external information storage medium such as a memory card.

  In addition, the storage unit 50 stores a game program 510A and game data for causing the processing unit 20 to function as the game calculation unit 210 in Application Example 1. To cause the game program 510A to function as the input range setting program 512A for functioning as the input range setting unit 212A, the input range display control program 514 for functioning as the input range display control unit 214, and the icon selection unit 216 The icon selection program 516 is included. The game data includes input range setting reference data 522A, input range setting data 524, and icon data 526.

(Process flow)
FIG. 15 is a flowchart for explaining a flow of icon selection processing in the first application example. This process is realized by the game calculation unit 210 executing the game program 510A during the execution of the game process. Note that the processing related to the progress of the game can be realized in the same manner as in the prior art, and thus description thereof is omitted here.

  According to the figure, in the icon selection process, first, the icon selection unit 216 displays an icon selection screen displaying a plurality of icon buttons IB on the image display unit 30 based on the icon data 526 (step A11). Next, the input range setting unit 212A sets the continuous detection count n to an initial value “0” as an initial setting (step A12). Thereafter, when the start of the touch operation is detected, the loop A process is executed every time the detection unit time Δt elapses until the end of the touch operation is detected.

  In the loop A, the input range setting unit 212A calculates the representative position Q from the touch positions P accumulated in the acquired touch position data 524a, that is, the plurality of touch positions P acquired during the detection unit time Δt (step S1). A13). Next, a distance L between the representative position Q and the reference position R is calculated, and the calculated distance L is compared with the determination reference distance Lb.

  As a result of the comparison, if the calculated distance L is less than or equal to the determination reference distance Lb (step A14: YES), the input range setting unit 212A determines that the same touch position P has been detected and sets the continuous detection count n to “ 1 ”is updated to the added value (step A15). Next, the continuous detection count n is compared with the change start count N. If the continuous detection count n is equal to or greater than the change start count N (step A16: YES), the radius r of the currently set input range IA is set as the radius. The change is made by increasing the increase amount Δr (step A17). If the continuous detection number n is not equal to or greater than the change start number N (step A16: NO), the representative position Q is set to the input range IA and updated (step A20).

  If the calculated distance L is not less than or equal to the determination reference distance Lb (step A14: NO), the input range setting unit 212A determines that the same touch position P is not detected and sets the continuous detection count n to “0”. Update (step A18). Then, the representative position Q is set as the reference position R (step A19), and the setting is updated with the representative position Q as the input range IA (step A20). If the reference position R is not set, the distance L cannot be calculated, and therefore it is determined that the distance L is not less than the determination reference distance Lb.

  Subsequently, the input range display control unit 214 identifies and displays the display of the set input range IA (step A21). At this time, the identification display already displayed, that is, the identification display of the area corresponding to the previously set input range IA is erased, and the area in the image display unit 30 corresponding to the input range IA set this time is identified. indicate.

In addition, the icon selection unit 216 determines whether or not the icon button IB is included in the set input range IA, sets the icon button IB determined to be included in the “selected state”, and sets the icon button IB to the icon button IB. It is highlighted so as to indicate that it is in a selected state (step A22).
The process of loop A is executed in this way.

When the end of the touch operation is detected, the process of loop A ends, and then the icon selection unit 216 determines the selection of the icon button IB in the selected state (step A23).
When the above processing is performed, the icon selection processing in Application Example 1 is completed.

<Application example 2>
Next, application example 2 will be described. In Application Example 2, the same elements as those in Application Example 1 described above are denoted by the same reference numerals, and detailed description thereof is omitted.

(Overview)
FIG. 16 is a diagram illustrating an outline of the application example 2, and illustrates an example of a game screen (screen overlooking a game space in a two-dimensional space) displayed on the display 3. According to the figure, on the game screen, a wall W (shaded portion in the figure) which is a kind of game object, a start mark ST indicating the start point, a goal mark GL indicating the goal point, and the player's A sphere BL that is an operation target character is displayed. The sphere BL has a minimum radius r ₀ as shown in FIG. The player moves the sphere BL from the start point to the goal point so as not to contact the wall W. The operation of moving the sphere BL is performed by performing a touch operation (sliding touch operation) so as to trace with the stylus pen 9 or a finger. When it is determined that the movement is stationary, the radius r increases and the sphere BL expands.

That is, as shown in FIG. 11A, when the start point is touched with a finger, for example, one point in the contact portion TA between the finger and the display 3 is set as the center position O, and the initial radius r ₀ is set as the radius r. The range to be set is set as the input range IA, and a sphere BL whose size is the set input range IA is displayed. The player moves the display 3 with the finger in contact so that the displayed sphere BL does not contact (intersect) the wall W (sliding touch operation).

  Further, when the finger is kept on contact with the display 3 as shown in FIG. 4B, the position where the finger is stopped, that is, one point in the contact portion between the fingertip and the display 3 is the center. The sphere BL (that is, the input range IA) gradually expands concentrically with time. When the sphere BL contacts (intersects) the wall W, it is determined that the game has failed at that time, and the game ends. Of course, even when the sphere BL is in contact with the wall W during the movement, it is determined as “game failure” at that time. Also, when the finger is released from the display 3 during the movement (end of the touch operation), it is determined as “game failure” at that time, and the game ends.

  Then, when the sphere BL reaches the goal GL without contacting the wall W as shown in FIG. 5C, it is determined as “game success” and the game ends.

  In the figure, the case where the touch operation is performed using the finger is shown, but the same applies to the case where the stylus pen 9 is used. That is, when the start position ST is touched, the position where the stylus pen 9 is in contact, that is, the detected touch position P is set as the center position O, and the initial radius r0 is set as the radius r is set as the input range IA. A sphere BL whose size is the input range IA is displayed. When the stylus pen 9 is brought into contact with the display 3 and stopped, the sphere BL (that is, the input range IA) is changed over time with the position where the stylus pen 9 is stopped (that is, the touch position P) as the center position O. Gradually expand.

Also, in Application Example 2, a level (game difficulty level) is set before the game starts, and a value (input range setting) serving as a reference when setting the input range IA (that is, the sphere BL) is set according to this level. Reference value) is set. Specifically, the higher the level, for example, the setting is made such that the change start count N decreases, the radius change amount Δr increases, or the initial radius r ₀ increases, and the difficulty of the game increases ( Difficult).

(Functional configuration)
FIG. 17 is a block diagram illustrating a functional configuration of the game apparatus 1 in the application example 2. As illustrated in FIG. According to the same figure, in application example 2, the game calculation unit 210 includes an input range setting unit 212B and a sphere control unit 218.

  First, the input range setting unit 212B sets the input range setting reference value according to the level data 528 based on the level selected and set by the player, for example.

  The level data 528 sets an input range setting reference value for each level. FIG. 18 shows an example of the data configuration of the level data 528. According to the figure, the level data 528 includes, for each level (528a), a detection unit time (528b), a change start count (528c), a determination reference distance (528d), a radius change amount (528e), The initial radius (528f) is stored in association with each other.

  As the detection unit time (528b), the value of the detection unit time Δt is set. The detection unit time (528b) is set so that the value decreases as the level (528a) increases. As the detection unit time Δr becomes smaller (shorter), the time interval for determining whether or not the same touch position P has been detected becomes shorter. Therefore, the higher the level, the higher the difficulty of the game.

  The change start count (528c) sets the value of the change start count N. This change start count (528c) is set so that the value decreases as the level increases. The smaller the change start count N is, the shorter the time (input range change start time Ts) until the change of the input range IA (that is, the sphere BL) is started when the stylus pen 9 or a finger is stopped. Therefore, the higher the level, the higher the difficulty of the game.

  The determination reference distance (528d) sets the value of the determination reference distance Lb. The determination reference distance (528d) is set so that the value increases as the level increases. As the determination reference distance Lb becomes larger (longer), the allowable range of movement in which it is determined that the same touch position P is detected becomes larger. Therefore, the higher the level, the higher the difficulty of the game.

  The radius change amount (528e) sets the value of the radius change amount Δr. The radius change amount (528e) is set so that the value increases as the level increases. The greater the radius change amount Δr, the faster the input range IA (that is, the sphere BL) expands. Therefore, the higher the level, the more difficult the game.

Initial radius (528f) sets the value of the initial radius r _0. The initial radius (528f) is set so that the value increases as the level increases. As the initial radius r ₀ is larger (longer), the initial size (minimum range) of the sphere BL (that is, the input range IA) set when touched with the stylus pen 9 or a finger becomes larger, and the level becomes higher. The more difficult the game becomes.

  The input range setting reference value set according to the level data 528 is stored in the input range setting reference data 522B. FIG. 19 shows an example of the data configuration of the input range setting reference data 522B. According to the figure, the input range setting reference data 522B includes a level (522B-1), a detection unit time (522B-2), a change start count (522B-3), and a determination reference distance (522B-4). And radius change amount (522B-5) and initial radius (522B-6) are stored. The input range setting reference data 522B is basically set before the game starts and is not changed while the game is in progress.

  The level (522B-1) stores, for example, a game level (difficulty level) value selected and set by the player. Each of the detection unit time (522B-2), the number of change start times (522B-3), the determination reference distance (522B-4), the radius change amount (522B-5), and the initial radius (522B-6) includes A value set in the level data 528 is stored in association with the level (522B-1).

Then, the input range setting unit 212B sets the input range IA according to the input range setting reference data 522B based on the touch operation signal input from the operation input unit 10. Specifically, when the start of the touch operation is detected, every time the predetermined detection unit time Δt elapses between the detection of the end of the touch operation, it is acquired during the detection unit time Δt. The representative position Q is calculated from the plurality of touch positions P, and it is determined whether or not the same touch position P is detected by determining whether or not the calculated representative position Q and the reference position R match. . Next, while the continuous detection count n does not reach the change start count N, the calculated representative position Q is set as the center position O, and a range in which the initial radius r ₀ is the radius r is set as the input range IA. When the continuous detection count n becomes equal to or greater than the change start count N, the radius r of the input range IA is increased by a radius change amount Δr each time the detection unit time Δt elapses. Each data acquired and calculated by the input range setting unit 212B is stored in the input range setting data 524.

The sphere control unit 218 controls the sphere BL based on the input range IA set by the input range setting unit 212A. Specifically, every time the input range IA is set by the input range setting unit 212A, the size of the sphere BL is changed so as to match the set input range IA. The center is moved to a position that coincides with the center position O of the set input range IA. At the start of the game (immediately after touching the start position), the sphere BL having the radius r as the initial radius r ₀ is set, and the set sphere BL is arranged at the touch position P (that is, the start position).

  In addition, the storage unit 50 stores a game program 510B and game data for causing the processing unit 20 to function as the game calculation unit 210 in Application Example 2. The game program 510B includes an input range setting program 512B for functioning as the input range setting unit 212B and a sphere control program 517 for functioning as the sphere control unit 218. The game data includes input range setting reference data 522B, input range setting data 524, level data 528, and stage data 532B.

  The stage data 532B is data of a game object such as a wall W in order to constitute a game stage. The stage data 532B includes image data representing game objects such as a wall W which is a game object, a start mark ST indicating a start position, a goal mark GL indicating a goal position, a size, an arrangement position, and the like. It is.

(Process flow)
FIG. 20 is a flowchart for explaining the flow of the game process in the application example 2. This process is realized by the game calculation unit 210 executing the game program 510B.

  According to the figure, in the game processing, the game calculation unit 210 first constructs a two-dimensional game stage in which the walls W, the start ST, the goal GL, etc. are arranged based on the stage data 532B, and the constructed game stage is displayed. The overlooked game screen is displayed on the image display unit 30 (step B11). Next, the input range setting unit 212B sets the continuous detection count n to an initial value “0” as an initial setting (step b12). When the game calculation unit 210 sets the level according to the player's operation input (step B13), the input range setting unit 212B sets the input range setting reference value according to the level data 528 based on the set level (step B14). ).

When the start position ST in the game screen is touched and the start of the touch operation is detected (step B15: YES), the sphere control unit 218 sets the sphere BL having the radius r as the initial radius r ₀ , The set sphere BL is placed at the touch position P (step B16). Thereafter, the loop B process is executed every time the detection unit time Δt elapses until the end of the touch operation is detected.

  In the loop B, the input range setting unit 212B calculates the representative position Q from the touch positions P stored in the acquired touch position data 524a, that is, the plurality of touch positions P acquired during the detection unit time Δt (step S1). B17). Then, the game calculation unit 210 determines whether or not the calculated representative position Q matches the goal position. If they match (step B18: YES), it determines that the game is successful and loops A. finish. Then, a predetermined game success effect process is executed (step B19).

  On the other hand, if the representative position Q does not match the goal GL (step B18: NO), then the input range setting unit 212B calculates the distance L between the representative position Q and the reference position R, and the calculated distance. L is compared with the determination reference distance Lb.

As a result of the comparison, if the distance L is less than or equal to the determination reference distance Lb (step B20: YES), the input range setting unit 212B determines that the same touch position P has been detected, and sets the continuous detection count n to “1”. The value is updated to the added value (step B21). Next, the continuous detection count n is compared with the change start count N. If the continuous detection count n is equal to or greater than the change start count N (step B22: YES), the radius r of the currently set input range IA is set as the radius. The change is made by increasing the increase amount Δr (step B23). Also, if the continuous detection number n not change start times N or more (step B22: NO), the representative position Q as the center position O, updated by setting the range of the initial radius r ₀ the radius r to the input range IA (Step B26).

  If the calculated distance L is not less than or equal to the determination reference distance Lb (step B20: NO), the input range setting unit 212B determines that the same touch position P is not detected and sets the continuous detection count n to “0”. Update (step B24). Then, the representative position Q is set as the reference position R (step B25), and the range having the representative position Q as the center position O and the initial radius r0 as the radius r is set as the input range IA and updated (step B26). ).

  Subsequently, the sphere control unit 218 changes the size of the sphere BL to the set input range IA and moves the center thereof to a position that coincides with the center position P of the input range IA (step B27). Then, the game calculation unit 210 determines whether or not the sphere BL and the wall W in the game screen intersect (intersection determination). If they intersect (step B28: YES), the game is determined to be unsuccessful. Then, the loop B is finished. Then, a predetermined game failure effect process is performed (step B29).

Loop B is executed in this way.
When the end of the touch operation is detected, the process of loop B ends, and when loop B ends, the game calculation unit 210 determines that the game has failed and performs a predetermined game failure effect process ( Step B29). Then, the game process in Application Example 2 ends.

<Action and effect>
As described above, according to the first embodiment, when the same position on the display 3 is continuously touched, the input range IA that was initially a “point” has a circular shape whose center is the touched position. As it changes to “region”, it gradually expands concentrically over time. That is, new input control is realized in which the input range IA changes when the same position is continuously touched.

  Therefore, when this input control is applied to the icon selection screen as in Application Example 1, even if the icon button IB to be actually selected is not touched, for example, by continuously touching the vicinity thereof, the input range over time When the IA expands and is included in the expanded input range IA, the icon button IB to be selected can be selected and input.

Further, as in Application Example 2, by applying this input control, a sliding touch operation is performed by tracing from the star position to the goal position so that the sphere BL set when touching the display 3 does not contact the wall W. It is possible to realize a game for inputting game operations. In this case, since the sphere BL gradually expands when the same position is continuously touched, it is possible to enjoy a game with a sense of speed that must be moved without stopping on the way. Further, an input range setting reference value (detection unit time Δt, change start frequency N, determination reference distance Lb, radius change amount Δr, initial radius r ₀ ) serving as a setting reference for the sphere BL (input range IA) is set as a game level ( By appropriately setting according to the degree of difficulty, the size of the sphere BL (input range IA) in the initial state is different, the speed at which the sphere BL (input range IA) is expanded, and so on. It will be an interesting game.

[Second Embodiment]
Next, a second embodiment will be described. In the second embodiment, the same elements as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.
In the second embodiment, the locus is input by an operation (sliding touch operation) of touching the display 3 with a stylus pen 9 or a finger and moving the display 3 while touching. By the way, in recent years, more precise (accurate) trajectory input is possible by improving the detection accuracy of the touch panel. However, in some cases, such high detection accuracy may not be required. The second embodiment is intended for a case where the accuracy of the detection accuracy of the touch panel 3 is not required in the locus input.

<Overview>
FIG. 21 is a diagram for explaining the outline of the second embodiment, and shows an example of a game screen (screen overlooking a game screen in a two-dimensional space) displayed on the display 3. According to the figure, in the second embodiment, an operation character CA that is controlled to move according to the player's operation input and a wall W that is a game object that blocks the movement of the operation character CA are displayed on the game screen. The The player touches the operation character CA with the stylus pen 9 or a finger, and moves the display 3 while keeping the stylus pen 9 or the finger in contact (sliding touch operation), thereby performing a game operation on the operation character CA. Enter.

  As shown in FIG. 5A, for example, when the operation character CA is touched with a finger and moved on the display 3 with the finger kept in contact (sliding touch operation), the movement trajectory is almost along the trajectory. The operation character CA moves.

  Specifically, as shown in FIG. 22, when a sliding touch operation is performed with a finger, the locus (touch locus) DR1 of the contact portion between the finger and the display 3 by the sliding touch operation is the contact portion. Since “is a“ surface ”, the trajectory has a certain width (thickness). A linear trajectory passing through the approximate center of the touch trajectory DR1 is generated as the input trajectory IR. Thereafter, the operation character CA is controlled to move along the generated input locus IR.

  Further, as shown in FIG. 21B, when the finger is moved so as to pass through the wall W (sliding touch operation), the operation character CA moves along the generated input locus IR. Since the portion W cannot be moved, the operation stops immediately before the wall W, that is, immediately before the position where the input trajectory IR and the wall W first intersect.

  In this case, as shown in FIG. 5C, after the finger is released from the touch panel 4 (end of the touch operation), the operation character CA is touched again, and the display 3 is moved with the finger kept in contact therewith. By moving, the operation character CA can be moved again.

<Principle>
FIG. 23 is a diagram for explaining the principle of input trajectory generation in the second embodiment. This figure shows the relationship between the touch position P acquired when the sliding touch operation is performed and the generation of the input trajectory IR, with the horizontal axis as time t.

  According to the figure, in the second embodiment, during a touch operation, for each predetermined detection unit time Δt, from a plurality of touch positions P acquired during the detection unit time Δt, the formula ( The representative position Q is calculated according to 1). The input locus IR is generated by performing a predetermined interpolation process based on the calculated representative positions Q. The interpolation process is realized by a known interpolation process such as linear interpolation or spline interpolation.

Specifically, while the touch operation is being performed, the input trajectory is partially generated every time a predetermined time elapses (partial trajectory generation). That is, as shown in the figure, the number of times that the representative position Q is calculated starting from the time t ₀ when the start of the touch operation is detected (hereinafter referred to as “representative position calculation frequency”) m is a predetermined portion. Each time the number of trajectory generation conditions M is reached, a partial trajectory is generated by performing interpolation processing based on the calculated M representative positions Q. Here, the number M of partial locus generation conditions corresponds to the number of representative positions Q that are the basis for generating the partial locus, and is set to a value of about several tens, for example. Therefore, the partial trajectory is generated every time Tr (= Δt × M) corresponding to the product of the detection unit time Δt and the partial trajectory generation condition number M (hereinafter referred to as “partial trajectory generation start time”). It will be. When the partial trajectory is generated, the operation character CA is controlled to move along the generated partial trajectory.

  Therefore, the generated input trajectory IR has a certain width as a trajectory of the contact portion between the finger and the display 3 as shown in FIG. 22 when the sliding touch operation is performed with the finger. This is a trajectory that passes through substantially the center of the (thick) touch trajectory DR1.

  When the sliding touch operation is performed with the stylus pen 9, as shown in FIG. 24, the locus (touch locus) DR2 of the contact portion between the stylus pen 9 and the display 3 is a single linear shape. It becomes a trajectory. The representative position Q calculated from the plurality of touch positions P constituting the touch locus DR2 is also substantially along the touch locus DR2. Therefore, the generated input trajectory IR is substantially along the touch trajectory DR2. Specifically, in the portion where the touch locus DR2 is substantially a straight line, the representative position Q substantially coincides with the touch locus DR2, and thus the generated input locus IR substantially coincides with the touch locus DR2. Further, in the portion where the touch locus DR2 draws a curve (or a corner), the representative position Q is a position that deviates from the touch locus DR2, and therefore, the generated input locus IR is a more gentle curve. That is, the generated input locus IR is obtained by gently correcting the inclination of the portion of the touch locus DR1.

<Functional configuration>
FIG. 25 is a block diagram illustrating a functional configuration of the game apparatus 1 according to the second embodiment. According to the same figure, in 2nd Embodiment, the game calculating part 210 contains the partial locus | trajectory production | generation part 222 and the character movement control part 224.

  The partial trajectory generation unit 222 generates a partial trajectory according to the partial trajectory generation reference data 534 based on the touch operation signal input from the operation input unit 10.

  The partial locus generation reference data 534 sets a value (partial locus generation reference value) that serves as a reference for the partial locus. FIG. 26 shows an example of the data configuration of the partial trajectory generation reference data 534. According to the figure, the partial locus generation reference data 534 sets a detection unit time (534a) and the number of partial locus generation conditions (534b). The partial trajectory generation reference data 534 is fixed data that is not changed through the progress of the process, but may be changed according to, for example, a player's setting input.

The detection unit time (534a) stores the value of the detection unit time Δt.
The partial trajectory generation start condition count (534b) sets the value of the partial trajectory generation condition count M. Each time the representative position Q is calculated (representative position calculation count) m reaches the partial trajectory generation condition count M, a partial trajectory is generated based on the calculated M representative positions Q.

  Then, each time the predetermined detection unit time Δt elapses, the partial locus generation unit 222 calculates the representative position Q from the plurality of touch positions P acquired during the detection unit time Δt. Then, every time the representative position Q is calculated (representative position calculation count) m reaches the partial trajectory generation condition number M, the partial trajectory is performed by performing predetermined interpolation processing based on the calculated M representative positions Q. Is generated.

  Each data acquired / calculated by the partial trajectory generation unit 222 is stored in the partial trajectory generation data 536. FIG. 27 shows an example of the data structure of the partial trajectory generation data 536. According to the figure, the partial trajectory generation data 536 stores acquired touch position data 536a, calculated representative position data 536b, a representative position calculation count (536c), and a movable flag (536d).

  The acquired touch position data 536a stores coordinate values of a plurality of touch positions P acquired during the detection unit time Δt. Each time one or more touch positions P detected by the touch panel 4 are acquired, the acquired touch positions P are accumulated in the acquired touch position data 536a. The acquired touch position data 536a is cleared every time the touch position Q is calculated, that is, every detection unit time Δt.

The calculated representative position data 536b stores the coordinate values of the latest M representative positions Q ₁ , Q ₂ ,..., Q _M among the representative positions Q calculated up to the present time. That is, each time the representative position Q is calculated, the calculated representative position data 536b stores the calculated representative position Q as the latest representative position Q _{M and} deletes and updates the representative position Q _1. .

  The representative position calculation count (536c) stores the value of the representative position calculation count m. The representative position calculation count (536c) is updated to a value obtained by adding “1” to the current value every time the representative position Q is calculated. When this value coincides with the partial trajectory generation count M, a partial trajectory is generated and updated to “0”. That is, the representative position calculation count (536c) stores the number of times the representative position Q is calculated after the latest partial locus is generated.

  The moveable flag (536d) stores the value of the moveable flag indicating whether or not the operation character CA can be moved. The moveable flag (536d) is movable at the start of the touch operation. It is set to “1” indicating that when moving along a partial trajectory and is blocked by a game object such as a wall W and cannot move any more, it is updated to “0” indicating that it cannot move. The

  The character movement control unit 224 performs control to move the operation character CA along the input trajectory IR generated by the partial trajectory generation unit 222. Specifically, every time a partial locus is generated by the partial locus generation unit 222, the operation character CA is moved along the generated partial locus. At this time, the character movement control unit 224 determines whether or not the generated partial trajectory and the wall W intersect if the movable flag is set to “1” indicating that movement is possible (intersection determination). ). As a result of the determination, if the character does not intersect, the operation character CA is moved along the generated partial trajectory. If the character intersects, the character is moved to a position just before the position where the partial trajectory and the wall W first intersect. The movable flag is updated to “0” indicating that the movable flag is not movable.

  The storage unit 50 also stores a game program 510C and game data for causing the processing unit 20 to function as the game calculation unit 210 in the second embodiment. The game program 510 </ b> C includes a partial trajectory generation program 518 for functioning as the partial trajectory generation unit 222 and a character movement control program 519 for functioning as the character movement control unit 224. The game data includes stage data 532C, operation character data 538, partial trajectory generation reference data 534, and partial trajectory generation data 536.

  The stage data 532C is data for arranging a game object such as a wall W to construct a game stage, and includes image data representing the wall W, data such as a size, and an arrangement position thereof.

  The operation character data 538 stores data related to the operation character CA. FIG. 28 shows an example of the data structure of the operation character data 538. According to the figure, the operation character data 538 stores the character ID (538a) for identifying the operation character CA, the model data (538b), and the current position (538c) in association with each other.

<Process flow>
FIG. 29 is a flowchart for explaining the flow of the game processing in the second embodiment. This process is realized by the game calculation unit 210 executing the game program 510C.

  According to the figure, in the game process, the game calculation unit 210 first constructs a game stage in which game objects such as walls W are arranged based on the stage data 532C, and operation character data in the constructed game stage. An operation character CA is arranged based on 538, and a game screen overlooking the game stage is displayed on the image display unit 30 (step C11). Next, as an initial setting, the continuous calculation count m is set to an initial value “0”, and a movable flag is set to “1” (step C12).

  When the operation character CA is touched and the start of the touch operation is detected (step C13: YES), until the end of the touch operation is detected, that is, while the sliding touch operation is broken, Every time the detection unit time Δt elapses, the process of the loop C is executed.

  In loop C, if the character movement control unit 224 determines the movable flag and the movable flag is set to “1” (step C14: YES), the partial trajectory generation unit 222 acquires the acquired touch position data 536a. The representative position Q is calculated from the plurality of touch positions P stored in the table, that is, the plurality of touch positions P acquired during the detection unit time Δt (step C15), and the representative position calculation count m is incremented by “1”. The value is updated (step C16).

Next, the partial trajectory generation unit 222 compares the representative position calculation count m with the partial trajectory generation condition count M, and if the representative position calculation count m matches the partial trajectory generation condition count M (step C17: YES). A predetermined locus is generated based on the _M representative positions Q ₁ , Q ₂ ,..., Q _M stored in the acquired touch position data 536a to generate a partial locus (step C18). Then, the representative position calculation count m is updated to “0” (step C19).

  Then, the character movement control unit 224 determines whether or not the generated partial trajectory and the wall W in the game screen intersect (intersection determination). If intersecting (step C20: YES), this partial trajectory. The operation character CA is moved to a position immediately before the position where the wall W intersects the wall W (step C21), and the movable flag is set to “0” (step C22). On the other hand, if the generated partial trajectory and the wall W do not intersect (step C20: NO), the operation character CA is moved along the partial trajectory (step C23).

The process of loop C is executed as described above.
When the end of the touch operation is detected, that is, when the sliding touch operation ends, the loop C ends. When the loop C ends, the game calculation unit 210 determines whether or not to end the game, and ends. If not (step C24: NO), the process proceeds to step C13 to execute the same processing. On the other hand, if the game is ended (step C24: YES), the game process in the second embodiment is ended.

<Action and effect>
As described above, according to the second embodiment, when a sliding touch operation is performed, a plurality of touch positions P acquired during the detection unit time Δt for each predetermined detection unit time Δt are averaged. Then, the representative position Q is calculated, and a predetermined interpolation process is performed based on the calculated representative position Q, whereby the input locus IR by the sliding touch operation can be generated. That is, since the input trajectory IR is generated not based on the detected touch position P itself but based on the representative position Q obtained by averaging the touch positions P, the trajectory input is in a sense lower than the detection accuracy of the display 3. It can be said that this control becomes possible.

  In particular, in the portable game apparatus 1, since the size of the display 3 is as small as, for example, a palm, display objects displayed on the display 3 inevitably become small, that is, a “passage” formed between the walls W. The width of becomes narrower. For this reason, for example, when a sliding touch operation is performed with a finger, it is difficult to move the finger so as not to contact the wall W (sliding touch operation) as compared with the case where the stylus pen 9 is used. Then, as shown in FIG. 22, a trajectory that passes near the center of the touch trajectory DR1 is generated as the input trajectory IR. Therefore, even when the finger is in contact with the wall W, it is regarded as “not in contact”, so that it is possible to input a trajectory that is advantageous to the player.

[Modification]
The application of the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.

(A) Changing the input range IA and continuing the identification display for a certain time In the first embodiment described above, the input range IA is changed only while the touch operation on the same position is continued. The change may be continued for a certain time after the touch operation on the same position is finished.

  That is, for example, as shown in FIG. 30A, when the stylus pen 9 is moved in a state where an input range IA which is a circular “area” is set, as shown in FIG. While the circular input range IA continues to expand, each input range IA set during the movement of the stylus pen 9, that is, each “point” along the movement locus is continuously identified. These input ranges IA are erased in order from the oldest (that is, the input range IA centered on the touch position P) after a predetermined time has elapsed. In this way, even after the touch operation on the same position is finished, the input range IA is expanded for a certain period of time, so that it is possible to express the input surplus. Further, the input range IA once set is displayed for a certain period of time even after the touch operation on the same position is completed, so that the remaining input state (residual state) can be expressed.

(B) Shape of Input Range IA In addition, in the first embodiment described above, the shape when enlarging the input range IA is circular, but other shapes may be used. Specifically, for example, as shown in FIG. 31, a ring shape is formed, and the inner radius ra (or outer radius rb) is increased by a predetermined radius change amount Δr while keeping the width w of the ring constant.
