JP 2010-103919 [H04M 1/00, H04M 1/275]

  However, in the portable information terminal disclosed in Patent Document 1, when a flick is performed, scroll display is performed in units of groups. In other words, since no consideration is given to the speed of flicking, an intuitive operation cannot be performed. Furthermore, no consideration is given to the operating environment. So, for example, in an environment where the humidity is high and the touch panel does not slide smoothly, even if the user recognizes that he / she flicks as usual, the flick speed is actually slower than usual and the scrolling May not be done very fast.

  Therefore, a main object of the present invention is to provide a novel portable terminal and its control program.

FIG. 5 is a diagram showing an example of a memory map of the RAM shown in FIG. FIG. 6 is a flowchart showing parameter setting processing of the processor shown in FIG. FIG. 7 is a flowchart showing display control processing of the processor shown in FIG.

  Referring to FIG. 1, a mobile phone 10 of this embodiment is a type of mobile terminal, and includes a processor 24 called a CPU or a computer. Connected to the processor 24 are a wireless communication circuit 14, an A / D converter 16, a D / A converter 20, a key input device 26, a display driver 28, a flash memory 32, a RAM 34, a touch panel control circuit 36, and a humidity sensor 40. Is done. An antenna 12 is connected to the wireless communication circuit 14, a microphone 18 is connected to the A / D converter 16, and a speaker 22 is connected to the D / A converter 20 via an amplifier (not shown). A display 30 is connected to the display driver 28. A touch panel 38 is connected to the touch panel control circuit 36.

  The processor 24 is an IC for control, and governs overall control of the mobile phone 10. The RAM 34 is used as a work area (including a drawing area) or a buffer area of the processor 24. The flash memory 32 stores content data such as characters, images, sounds, sounds and videos of the mobile phone 10 and data such as a user profile and an address book.

  The A / D converter 16 converts an analog audio signal for audio or sound input through the microphone 18 connected to the A / D converter 16 into a digital audio signal. The D / A converter 20 converts (decodes) the digital audio signal into an analog audio signal, and supplies the analog audio signal to the speaker 22 via the amplifier. Therefore, sound or sound corresponding to the analog sound signal is output from the speaker 22.

  The key input device 26 includes a call key 26a, a function key 26b, an end call key 26c, and the like (see FIG. 2A). Then, information (key data) on the keys operated by the user is input to the processor 24. When each key included in the key input device 26 is operated, a click sound is generated. The user can obtain an operational feeling with respect to the key operation by listening to the click sound.

  The display driver 28 controls display on the display 30 connected to the display driver 28 under the instruction of the processor 24. The display driver 28 includes a VRAM (not shown) that temporarily stores display image data corresponding to the screen displayed on the display 30. The processor 24 stores the display image data in this VRAM.

  The touch panel 38 is a pointing device for instructing an arbitrary position within the screen of the display 30. For example, the touch panel 38 of this embodiment is a capacitive touch panel that detects a change in capacitance between electrodes that occurs when an object such as a finger approaches the surface, and includes, for example, one or a plurality of touch panels. It is possible to detect that a finger has touched the touch panel 38. Further, when the touch panel 38 is operated by pressing, stroking, or touching the surface (upper surface) with a finger, the touch panel 38 detects the operation. Specifically, the touch panel control circuit 36 functioning as a touch detection unit specifies the position of the finger when the finger touches the touch panel 38, and coordinates data (coordinate data) indicating the operated position (touch position). Is output to the processor 24. That is, the user can input the operation position, operation direction, figure, and the like to the mobile phone 10 by pressing, stroking, or touching the upper surface of the touch panel 38 with a finger.

  Hereinafter, in this embodiment, an operation in which the user touches the upper surface of the touch panel 38 with a finger is referred to as “touch”. On the other hand, the operation of releasing the finger from the touch panel 38 is referred to as “release”. The operation of stroking the upper surface of the touch panel 38 with a finger is referred to as “slide”. Furthermore, an operation of flipping or touching the upper surface of the touch panel 38 with a finger is referred to as “flick”. Specifically, the flick is an operation of moving (sliding) a predetermined distance (for example, 50 dots) or more within a predetermined time (for example, 50 ms) while keeping the finger in contact with the upper surface of the touch panel 38 and releasing the finger. The coordinates indicated by the touch are referred to as “touch point (touch start position)”, and the coordinates indicated by the release are referred to as “release point (touch end position)”. Further, an operation in which the user touches the upper surface of the touch panel 38 and subsequently releases it is referred to as “touch and release”. An operation performed on the touch panel 38 such as touch, release, slide, flick, and touch and release is generally referred to as “touch operation”.

  Note that the touch operation is not limited to a finger, and may be performed by other objects such as a touch pen with a conductor attached to the tip. Further, as a detection method of the touch panel 38, a surface-type capacitance method may be employed, or a resistance film method, an ultrasonic method, an infrared method, an electromagnetic induction method, or the like may be used.

  The humidity sensor 40 detects humidity (%), and provides the processor 24 with data (humidity data) regarding the detected humidity. The humidity sensor 40 is a general-purpose humidity sensor. For example, a humidity sensor module (model number: HSU-04A1-N) manufactured by Hokuriku Electric Co., Ltd. or a digital temperature / humidity sensor (model number: SHT2x) manufactured by Sensirion Co., Ltd. is used. Can be used.

  The wireless communication circuit 14 is a circuit for performing wireless communication by the CDMA method. For example, when the user instructs voice transmission using the key input device 26, the wireless communication circuit 14 performs voice transmission processing under the instruction of the processor 24 and outputs a voice transmission signal via the antenna 12. The voice transmission signal is transmitted to the other party's telephone through a base station and a communication network (not shown). When an incoming call process is performed at the other party's telephone, a communicable state (connection state) is established, and the processor 24 executes a call process.

  The normal call processing will be described in detail. The modulated audio signal transmitted from the other party's telephone is received by the antenna 12. The received modulated audio signal is demodulated and decoded by the wireless communication circuit 14. The received voice signal obtained by these processes is converted into an analog voice signal by the D / A converter 20 and then output from the speaker 22. On the other hand, the transmission voice signal captured through the microphone 18 is converted into a digital voice signal by the A / D converter 16 and then given to the processor 24. The transmission voice signal converted into the digital voice signal is subjected to coding processing and modulation processing by the wireless communication circuit 14 under the instruction of the processor 24, and is output via the antenna 12. Therefore, the modulated voice signal is transmitted to the other party's telephone through the base station and the communication network.

  When the outgoing signal from the other party's telephone is received by the antenna 12, that is, when there is an incoming call, the wireless communication circuit 14 notifies the processor 24 of an incoming voice call (sometimes called an incoming call). In response to this, the processor 24 controls the display driver 28 to display the caller information (such as the name of the caller (partner)) described in the incoming call notification on the display 30. At substantially the same time, the processor 24 outputs a ringtone (may be called a ringing melody or a ringing voice) from a speaker (not shown) different from the speaker 22.

  In addition, when the mobile phone 10 is provided with a vibration device (vibrator) or an LED, the incoming call can be notified by driving the light or vibration (flashing) or both. This may be performed with the ringtone described above.

  When the user instructs to respond to the incoming call, the wireless communication circuit 14 executes a voice incoming call process under the instruction of the processor 24, establishes a communicable state, and the processor 24 Execute the process.

  In addition, when a call end operation is performed by the call end key 26c after the transition to the call ready state, the processor 24 controls the wireless communication circuit 14 to transmit a call end signal to the call partner. After transmitting the call end signal, the processor 24 ends the call process. The processor 24 also ends the call process when a call end signal is received from the other party first. Furthermore, the processor 24 also ends the call process when a call end signal is received from the mobile communication network regardless of the call partner.

  Further, the mobile phone 10 can execute a plurality of functions by establishing data communication with a server connected to the network. For example, the mobile phone 10 can execute a mail function for sending and receiving mail and a browser function for acquiring data published by the server by establishing data communication with a mail server (not shown).

  FIG. 2A is an external view showing the external appearance of the front surface of the mobile phone 10, and FIG. 2B is an external view showing the external appearance of the back surface of the mobile phone 10. Referring to FIG. 2A, the mobile phone 10 has a straight shape and includes a casing 50 having a flat rectangular shape. The microphone 18 described above is built in the housing 50. The opening OP <b> 2 leading to the built-in microphone 18 is the surface of the housing 50 and is provided at one end in the longitudinal direction of the housing 50. Similarly, the above-described speaker 22 is built in the housing 50. The opening OP <b> 1 leading to the built-in speaker 22 is the surface of the housing 50 and is provided at the other end in the longitudinal direction of the housing 50. Similarly, the humidity sensor 40 described above is built in the housing 50. The opening OP3 leading to the built-in humidity sensor 40 is the surface of the housing 50 and is provided at a corner on the side where the opening OP1 is provided. However, the opening OP3 and the humidity sensor 40 may be provided at other positions as long as the position can detect humidity. The display 30 is attached so that the monitor screen is exposed from the housing 50. Although not expressed in FIG. 2A, the touch panel 38 described above is provided on the upper surface (front surface) of the display 30.

  As shown in FIG. 2A, the key input device 26 includes a call key 26a, a function key 26b, and an end key 26c. These keys are the surface of the housing 50 and are provided between the display 30 and the opening OP2.

  For example, the user inputs a telephone number by performing a touch operation on a dial key displayed on the display 30, and performs a voice call operation using the call key 26a. When the call ends, the user performs a call end operation using the end call key 26c. In addition, the user selects and confirms the menu by performing a touch operation on the soft keys and the menu displayed on the display 30. Then, the user turns on / off the power of the mobile phone 10 by pressing and holding the end call key 26c.

  The antenna 12, the wireless communication circuit 14, the A / D converter 16, the D / A converter 20, the processor 24, the display driver 28, the flash memory 32, the RAM 34, and the touch panel control circuit 36 are built in the housing 50. Therefore, it is omitted in FIGS. 2 (A) and 2 (B).

  For example, when the address book function is executed, an address book screen 60 as shown in FIG. The address book screen 60 includes three display screens 60a, 60b and 60c. The display screen 60a displays the radio wave intensity, the remaining battery level, and the date and time. The display screen 60b displays an index (here, an image and a name) about display contents displayed on the display screen 60c. The display screen 60c displays an image and a name for a person registered in the address book. However, when an image of a person is not registered, a symbol indicating that the image is not registered is displayed. In the name column, a character string such as a name registered by the user of the mobile phone 10 is displayed.

  In such an address book screen 60, when the user slides upward or downward on the screen, the display content (image and name) displayed on the display screen 60c is moved (changed) in the sliding direction. For example, from the state shown in FIG. 3A, as shown in FIG. 3B, when the user slides upward, the display content displayed on the display screen 60c is moved upward along with the movement of the sliding finger. Moving. That is, the display screen 60c is scrolled downward. Although illustration and description are omitted, when sliding downward, the direction of scrolling is reversed from when sliding upward.

  When scrolling at high speed, the user flicks upward or downward. Although it is difficult to understand in the drawing, when the user flicks upward as shown in FIG. 3C from the state shown in FIG. 3A, unlike the case of the slide, the display screen 60c is moved upward at high speed. Scrolled. However, in the case of a flick, the finger is released after sliding (playing).

  In this embodiment, the case where the address book function is executed is shown. However, even when the map function is executed or the schedule book function is executed, the user's The screen is scrolled at high speed according to the flick. Therefore, the scroll direction may be not only the vertical direction but also the horizontal direction or the diagonal direction.

  FIG. 4 is a diagram for conceptually explaining the relationship between the drawing area 100 of the VRAM and the display area 102 of the display 30. Here, for the sake of simplicity, it is assumed that the entire range of the screen of the display 30 corresponds to the display area 102 shown in FIG. 4, and the entire screen is scrolled.

  Although detailed description is omitted, the display image data of the display area that is not scrolled, such as the display screens 60a and 60b of the address book screen 60 described above, is an area different from the scrolled display area such as the display screen 60c. Is drawn.

  As shown in FIG. 4, the VRAM drawing area 100 is set larger than the display area 102. As shown in FIG. 4, the flick directions can be classified into eight directions indicated by white arrows with (1) to (8). However, the flick direction and the scroll direction are opposite. For example, when the direction of the flick is the direction of the white arrow with (2), the moving direction of the display area 102, that is, the direction of scrolling is the direction of the white arrow with (6). . The same applies to other cases.

  Although detailed description is omitted, the direction of scrolling is also the direction indicated by the white arrow in FIG. Therefore, strictly speaking, the direction of the flick needs to be changed by 45 ° clockwise or counterclockwise when the direction of the arrow with (1) is 0 °. However, since it is an operation with a user's finger, it is difficult to indicate the correct direction. Therefore, data in the direction indicated by the white arrow as shown in FIG. 4 is stored, and the flick direction is determined in the direction of the arrow closest to the direction calculated according to Equation 2. However, with respect to the oblique direction, the calculated flick direction may be scrolled in the direction opposite to the calculated flick direction without being determined as the direction of the white arrow that most closely approximates.

  Although detailed description is omitted, the speed and direction of the flick are detected, and the display content is moved in the direction at a speed or / and acceleration corresponding to the speed. However, the speed of flick is calculated by calculating the distance between any two touch positions among a plurality of touch positions detected according to the time series, and dividing the two touch positions by the difference in time detected. Desired. The flick direction is a vector direction from a touch position detected earlier in time to a touch position detected later in time at two touch positions of the plurality of touch positions.

Specifically, the speed v _f and the flick direction d _f flick, respectively, are calculated by equations 1 and 2. However, the coordinates of the point P1 on the VRAM drawing area corresponding to the touch position detected at time t1 are (x1, y1), and the VRAM drawing area corresponding to the touch position detected at time t2 (> t1). Let the coordinates of the upper point P2 be (x2, y2). In the VRAM drawing area, the origin O (0, 0) is determined in advance, and a two-dimensional coordinate system (XY axis) centered on the origin O is also determined. Although omitted in FIG. 4, the origin O (0, 0) is set at the center of the drawing area of the VRAM, for example. Further, the X axis is set in the horizontal direction and the Y axis is set in the vertical direction so as to be orthogonal at the origin O (0, 0). Furthermore, the right direction is the positive direction of the X axis, and the upward direction is the positive direction of the Y axis. Therefore, the direction d _f of the flick is the direction of the vector when relative to the origin O.

[Equation 1]
^{_{v f = (√ {(x2}} -x1) 2 + (y2-y1) 2}) / (t2-t1)
[Equation 2]
d _f = (x2-x1, y2-y1)
Also, for example, when flicking, the moving distance of the display content, that is, the scrolling distance S is determined according to Equation 3. Here, a is the scroll acceleration, v is the scroll speed, and t is the scroll time.

[Equation 3]
S = vt + 1/2 × at ²
Normally, the scroll time t is a fixed time (for example, 0.5 to 1 second), and at least one of the scroll speed v and the scroll acceleration a is variably set according to the flick speed v _f. . This realizes a scroll in accordance with the velocity v _f of the flick. That is, if at least one of the scrolling speed v and the scrolling acceleration a is large, the scrolling distance becomes longer during a certain scrolling time t. Therefore, the larger the velocity v _f of the flick is being scrolled faster.

However, the scroll speed v is represented by kv ₀ , and the scroll acceleration a is represented by ma ₀ . v ₀ is an initial value of the scroll speed v, and a ₀ is an initial value of the scroll acceleration a. In this embodiment, the initial value v ₀ is set to the same value as the flick speed v _f . The initial value a ₀ is a value preset by the designer or developer of the mobile phone 10. The coefficient k and the coefficient m is set according to the flick of the velocity v _f. For example, when the speed v _f of the flick is equal to or larger than the predetermined threshold value A, the coefficient k and the coefficient m is greater than 1 (e.g., 1.2) is set, flick velocity v _f is a predetermined threshold value When it is less than B (B <A), the coefficient k and the coefficient m are set to values smaller than 1 (for example, 0.8). When the flick speed v _f is equal to or greater than the threshold value B and equal to or less than the threshold value A, the coefficient k and the coefficient m are set to 1.

In this embodiment, the threshold value A and the threshold value B are set, and the coefficient k and the coefficient m are set to predetermined values in accordance with the magnitude of the flick speed v _f . However, the coefficient k and the coefficient m are calculated. Or may be determined using a preset table. However, as the velocity v _f of the flick is large, it is necessary acceleration a scrolling speed v and the scroll is increased.

  However, in an environment where the humidity is high, the display 30 and / or the finger are in a moist state, and the finger hardly slides on the upper surface of the display 30 when sliding or flicking. As described above, in the case of a slide, the screen is scrolled by moving the display content with the movement of the finger, so there is no sense of incongruity, but in the case of a flick, the usual operation is performed. In spite of this, there are cases where the user feels that the scrolling speed is slow. That is, there is a risk of feeling uncomfortable.

  Therefore, in this embodiment, by detecting the humidity, the scroll speed v and the scroll acceleration a are changed according to the humidity. That is, the set values of the scroll speed v and the scroll acceleration a are controlled.

Specifically, in Equation 3, the velocity v of the scroll, the initial value v ₀ to further multiplied by the coefficient α (v = αkv ₀₎ is determined by the acceleration a of the scroll is furthermore coefficient to the initial value a ₀ beta Multiplied by (a = βma ₀ ). Then, the scroll speed v and the scroll acceleration a are changed by changing the coefficient α and the coefficient β.

In this embodiment, in order to set the coefficient α and the coefficient β (parameter), two threshold values (threshold value C and threshold value D) having different sizes are provided. However, the threshold value C is larger than the threshold value D. The threshold value C and the threshold value D are values determined (set) by experiments or the like. In this embodiment, when the humidity is greater than or equal to the threshold value D and less than the threshold value C, that is, when the humidity is medium, the coefficient α and the coefficient β are initially set to the first set value (in this embodiment, 1 ) Is set. In this case, based on only the flick velocity v _f, scrolling speed v and the scroll of the acceleration a is varied. In this embodiment, when the humidity is less than the threshold value D, that is, when the humidity is relatively low, the second set value (0.8 in this embodiment) is set to the coefficient α and the coefficient β. Is done. Therefore, the scroll speed v and the scroll acceleration a are reduced.

  FIG. 6 is a flowchart showing the parameter setting process of the processor 24 shown in FIG. As described above, the parameter setting process is executed at a predetermined timing such as when a predetermined time (1 hour in this embodiment) elapses when the use of the mobile phone 10 is started.

  As shown in FIG. 6, when the processor 24 starts the parameter setting process, in step S1, the coefficient α and the coefficient β are initialized (α = β = 1). That is, initial value data is set in the coefficient α data 304f and the coefficient β data 304g. In the next step S3, the humidity is detected. That is, the processor 24 acquires the humidity data 304 c from the humidity sensor 40 and stores it in the data storage area 304. Subsequently, in step S5, it is determined whether or not the humidity is equal to or higher than a threshold value C. If “YES” in the step S5, that is, if the humidity is equal to or higher than the threshold value C, the coefficient α is set to 1.2 (α = 1.2) in a step S7, and the coefficient β is set to 1. 2 is set (β = 1.2), and the parameter setting process is terminated. That is, the coefficient α data 304f and the coefficient β data 304g are updated by the processes in steps S7 and S9.

  If “NO” in the step S5, that is, if the humidity is less than the threshold value C, it is determined whether or not the humidity is less than the threshold value D in a step S11. If “NO” in the step S11, that is, if the humidity is greater than or equal to the threshold value D and less than the threshold value C, the parameter setting process is ended as it is. On the other hand, if “YES” in the step S11, that is, if the humidity is less than the threshold value D, the coefficient α is set to 0.8 (α = 0.8) in a step S13, and the coefficient β is set in a step S15. Set to 0.8 (β = 0.8), and the parameter setting process ends. That is, the coefficient α data 304f and the coefficient β data 304g are updated by the processes of steps S13 and S15.

  FIG. 7 is a flowchart showing the display control processing of the processor 24 shown in FIG. Although detailed description is omitted, the display control process is executed every predetermined time (one frame). As shown in FIG. 7, when the display control process is started, the processor 24 determines whether or not a flick is made in step S31. Here, the processor 24 refers to the coordinate data stored in the operation data buffer 304a, and releases the user after moving the finger within a predetermined time (for example, 50 ms) by a predetermined distance (for example, 50 dots). Judge whether.

If in step S31 "YES", that is, if the flick, in step S33, according to the equation 1 calculates a flick velocity _{v f,} in step S35, according to Equation 2, to calculate the direction _{d f} of the flick. Although not illustrated, in step S33, flick velocity data 304d corresponding to the calculated flick velocity _{v f} is stored in the data storage area 304 of the RAM 34, in step S35, it corresponds to the direction _{d f} of the calculated flick The flick direction data 304e to be stored is stored in the data storage area 304 of the RAM 34. Then, in step S37, the flick direction d _f in the reverse direction, the screen is scrolled to the acceleration a of the scroll speed v and scrolling, and ends the display control process. However, in step S37, the scroll speed v (= αkv ₀ ) and the scroll acceleration a (= βma ₀ ) are determined according to the flick speed v _f and humidity as described above.

  If “NO” in the step S31, that is, if it is not a flick, it is determined whether or not there is another operation in a step S39. For example, it is determined whether there is an operation based on key data or an operation such as slide or touch and release. If “NO” in the step S39, that is, if there is no other operation, it is determined that there is no operation, and the display control process is ended as it is. On the other hand, if “YES” in the step S39, that is, if there is another operation, a display process corresponding to the other operation is executed, and the display control process is ended. For example, in step S41, the processor 24 scrolls the screen, enlarges or reduces the screen, or moves to another page (screen) according to the slide or touch and release.

  According to this embodiment, when the humidity is high, the speed and acceleration for moving a part or all of the display content of the screen are increased, and when the humidity is low, the display content of a part or all of the screen is displayed. Since the moving speed and acceleration are reduced, the amount by which part or all of the display content of the screen is moved can be made constant according to the user's flick, regardless of changes in humidity. That is, the operational feeling can be made uniform.

  In this embodiment, not only when the humidity is high, but also when the humidity is low, the speed and acceleration for moving part or all of the display contents of the screen are changed. Does not have to change its speed and acceleration. Alternatively, only when the humidity is low, the speed and acceleration at which part or all of the screen is moved may be changed.

  In this embodiment, two threshold values are provided for determining whether the humidity is high or low, and the speed and acceleration of moving part or all of the display contents of the screen at the threshold value C or more and less than the threshold value D, respectively. Although the parameters (coefficients α and β) for changing at least one of them are set to predetermined values, it is not necessary to be limited to this. For example, the coefficients α and β may be calculated according to humidity, or the coefficients α and β may be determined according to a table prepared in advance. However, in any case, as the humidity increases, the coefficients α and β are set so that the speed and acceleration for moving part or all of the display contents of the screen are increased. As the humidity decreases, the coefficients α and β are set so that the speed and acceleration at which part or all of the display content of the screen is moved are reduced.

  Further, in this embodiment, the mobile phone is provided with a humidity sensor, and the scroll speed and the scroll acceleration are set according to the humidity detected by the humidity sensor. However, the present invention is not limited to this. Absent. For example, the base station may notify the local humidity information, and the mobile phone may acquire the humidity information. Alternatively, the mobile phone may be provided with a GPS function to acquire the current position, and the humidity at the current position may be acquired from a predetermined Internet site.

  Furthermore, in this embodiment, both the scroll speed and the scroll acceleration are changed according to the humidity, but either one may be changed. Specifically, when only the scrolling speed is changed, the processes in steps S9 and S15 in FIG. 6 may be deleted. In this case, it is not necessary to initialize the coefficient β in step S1. On the other hand, when only the scroll acceleration is changed, the processes in steps S7 and S13 in FIG. 6 may be deleted. In this case, it is not necessary to initialize the coefficient α in step S1.

  Furthermore, in this embodiment, only the cellular phone provided with the touch panel has been described, but it is not necessary to be limited to this. The present invention can also be applied to other portable terminals such as a tablet PC having a touch panel and an electronic camera.

  Furthermore, in this embodiment, after being released, scrolling is performed at a predetermined speed for the distance shown in Equation 3. For example, the scroll time t after release (for example, 1 second here) And the released acceleration a may be set to a negative value so that the screen moves a distance S and stops gradually during the scroll time t. Further, the value of the acceleration a may be variably set so that after the first half (for example, 0.5 seconds) of the scroll time t, the second half (the remaining, 0.5 seconds) is decelerated. .

  In this embodiment, the CDMA system is adopted as the communication system. However, the present invention is not limited to this. The LTE (Long Term Evolution) system, the W-CDMA system, the GSM system, the TDMA system, Other methods such as an FDMA method and a PHS method may be adopted.
