JP 2012-44474 A (published March 1, 2012) JP 2008-33743 A (published February 14, 2008) JP 2009-295147 A (released on December 17, 2009) JP 2009-17486 A (released on January 22, 2009) JP 2010-211881 A (published on September 24, 2010) JP 2006-302348 A (published November 2, 2006)

  Based on FIG. 6, the problem of the conventional electronic device will be described in detail. FIG. 6 is a schematic diagram showing the relationship of variables necessary for the calculation for moving the locator 7 in the seek bar 6 displayed on the conventional electronic device.

  As shown in FIG. 6, when the remaining time of the content is R [seconds] and the length of the seek bar 6 corresponding to the remaining time of the content is 1 [m], the user moves the locator 7 by b [m]. In such a case, the electronic device outputs the content from the portion advanced by R × b / l [seconds]. In the conventional electronic device, there is a problem that it is difficult for the user to specify the advanced part when the remaining time of the content is long.

  For example, when R = 1800 seconds (30 minutes) and the user wants to advance the content by 60 seconds (1 minute), even if l = 0.05 m (50 mm), the locator 7 is b = 0. The user must operate the locator so as to move by a minute distance of .0017 m (1.7 mm). It is almost impossible to perform the above operation with the performance of the input device detecting the operation and the accuracy of human operation.

  None of the prior arts described in Patent Documents 1 to 6 described above can reliably solve the above-described problems occurring in conventional electronic devices, or cause another problem as the above-mentioned problems are solved. .

  For example, according to the device described in Patent Document 2 or 3 above, the vicinity of the position of the locator is displayed on a separate interface, but the operation for finely adjusting the position of the locator can be performed by mixing a plurality of interfaces. Complex and not intuitive.

  Further, according to the device described in Patent Document 4, since the scale is accelerated as the position specified by the user deviates from the current position of the locator, the user moves the distance between the locator and the distance the user moves the finger. Difficult to understand the relationship with position. Similarly, other patent documents cannot solve the above-mentioned problem reliably.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to make it easy to specify a time during which content output has progressed and to improve user convenience when outputting the content. It is to provide an information processing apparatus and the like that can be used.

In order to solve the above problems, an information processing apparatus of the present invention
(1) Provided with a seek bar indicating the progress of output of content by the output device as the locator moves, and by sending the position of the locator in the seek bar, it is possible to specify the time when the output device has advanced the output of the content Information processing apparatus,
(2) When a user operation is detected at an arbitrary position on the input surface, further detection is performed by moving the first designated position detected by the input surface and the user operation along the input surface. Obtaining means for obtaining a length of a trajectory connecting the designated second designated position;
(3) detection means for detecting that the length of the trajectory acquired by the acquisition means exceeds a predetermined threshold;
(4) a determination means for determining whether or not the second designated position matches the position of the locator when it is detected that the detection means is exceeding,
(5) If it is determined by the determination means that they do not match, a setting means for setting a ratio at which the user's operation and the movement of the locator are linked;
(6) A position on the seek bar that can be calculated from the length of the trajectory acquired by the acquisition unit and the ratio set by the setting unit, and a position in the direction toward the second designated position, And sending means for sending it as the position of the locator moved by the user's operation.

In addition, in order to solve the above-described problem, a method for controlling the information processing apparatus of the present invention includes:
(1) Provided with a seek bar indicating the progress of output of content by the output device as the locator moves, and by sending the position of the locator in the seek bar, it is possible to specify the time when the output device has advanced the output of the content A method for controlling an information processing apparatus,
(2) When a user operation is detected at an arbitrary position on the input surface, further detection is performed by moving the first designated position detected by the input surface and the user operation along the input surface. An acquisition step of acquiring a length of a trajectory connecting the designated second position;
(3) a detection step of detecting that the length of the trajectory acquired in the acquisition step exceeds a predetermined threshold;
(4) a determination step of determining whether or not the second designated position matches the position of the locator when it is detected that the value exceeds the detection step;
(5) If it is determined in the determination step that they do not match, a setting step for setting a ratio at which the user's operation and the movement of the locator are linked;
(6) A position in the seek bar that can be calculated from the length of the trajectory acquired in the acquisition step and the ratio set in the setting step, the position being in the direction toward the second designated position, And a sending step for sending out the position of the locator moved by the user's operation.

  As described above, according to the related art, the problem that it is difficult for the user to specify the time for which the user has made progress cannot be reliably solved, or another problem is caused as the problem is solved. Create a challenge. For example, when a plurality of interfaces are mixed, the operation for finely adjusting the position of the locator becomes complicated, or the user has difficulty in understanding the relationship between the distance to which the finger is moved and the position of the locator.

  On the other hand, according to the above configurations (1) to (6), the information processing apparatus and the control method for the apparatus according to the present invention can be controlled by the input surface when a user operation is detected at an arbitrary position on the input surface. A length of a trajectory connecting the detected first designated position and the second designated position further detected when the user's operation moves along the input surface is acquired.

  In other words, the information processing apparatus or the like acquires an arbitrary position on the input surface designated by the user at a predetermined time interval from the input surface, and the first designated position obtained at a certain timing, The length (distance) from the second designated position acquired at the timing is acquired. That is, since the length is a distance per the predetermined time interval, it is equivalent to the speed at which the user moves the designated position along the input surface.

  Next, when the information processing apparatus detects that the length of the acquired trajectory exceeds a predetermined threshold value, whether or not the second designated position matches the position of the locator Determine. If it is determined that they do not match, the information processing apparatus or the like sets a ratio at which the user's operation and the movement of the locator are linked, and the position on the seek bar that can be calculated from the length of the trajectory and the ratio. Thus, the position in the direction toward the second designated position is transmitted as the position of the locator moved by the user's operation.

  That is, according to the information processing apparatus and the control method of the apparatus of the present invention, the distance that the user moves the designated position at a predetermined time interval along the input surface is large, and the second designated position and the position of the locator are Are deviated from each other, the position of the moved locator is determined to be a position close to the second designated position and transmitted.

  In addition, since only a unified interface for adjusting the position of the locator is provided to the user, the operation is not complicated as in the prior art. In addition, since the scale width of the seek bar remains unchanged, the user can easily understand the relationship between the distance to which the finger is moved and the position of the locator.

  Therefore, the information processing apparatus and the control method for the apparatus according to the present invention can eliminate the state where the designated position and the locator are separated from each other, so that the user does not feel uncomfortable in operation. Thereby, the information processing apparatus and the control method for the apparatus according to the present invention can easily specify the time that the user has made progress, and can improve the convenience of the user when the content is output.

In the information processing apparatus of the present invention,
(1) The sending means moves the locator from the current locator position on the seek bar by the amount of movement obtained by multiplying the length of the trajectory obtained by the obtaining means by the ratio set by the setting means. The position moved in the direction toward the second designated position is transmitted as the position of the locator moved by the user's operation.

  According to said structure (1), the said information processing apparatus calculates the movement amount of a locator by multiplying the length of the said locus | trajectory to the said ratio. Then, the information processing apparatus sends the position where the locator is moved in the direction toward the second specified position from the current position of the locator on the seek bar as the position of the locator moved by the user's operation. To do.

  For example, when the ratio is set to 2.0, a length twice the length is calculated as the movement amount, and the locator moves by the double length. That is, the locator moves by a longer distance (moves faster) than the distance that the user moves the specified position along the input surface at predetermined time intervals.

  Therefore, the information processing apparatus according to the present invention can effectively eliminate the state where the designated position and the locator are separated from each other, so that the user does not feel uncomfortable in operation. Thereby, the information processing apparatus of the present invention makes it easy for the user to specify the progressed time, and can further improve the convenience of the user when outputting the content.

In the information processing apparatus of the present invention,
(1) The setting unit sets the interlocking ratio so that the position of the locator calculated from the length of the trajectory and the interlocking ratio matches the second designated position. Yes.

  According to said structure (1), the said information processing apparatus sets a ratio so that the position of the locator calculated from the ratio linked | related with the length of a locus | trajectory may correspond with a 2nd designated position. Thereby, the information processing apparatus can eliminate the state where the specified position and the locator are separated from each other, and does not give the user a sense of incongruity in operation.

  Therefore, the information processing apparatus of the present invention makes it easy for the user to specify the time for which the progress has been made, and can further improve the convenience of the user when outputting the content.

In the information processing apparatus of the present invention,
(1) The determination means further determines whether or not the movement of the locator is delayed with respect to the direction from the first designated position to the second designated position,
(2) When the determination unit determines that the movement of the locator is delayed by the determination unit, the setting unit sets a value corresponding to the length of the trajectory to the interlocked ratio and a value of 1 or more, When it is determined that the movement of the locator is not delayed, a value corresponding to the length of the locus and set to 1 or less is set as the interlocking ratio.

  According to said structure (1)-(2), the said information processing apparatus is with respect to the direction (advancing direction of the user's finger | toe which contacted the input surface) which goes to a 2nd specified position from a 1st specified position. When the movement of the locator is delayed, a value corresponding to the length of the trajectory and a value of 1 or more is set as the ratio, and when it is not delayed, the value according to the length of the trajectory is 1 or less. Set the value to a ratio.

  Therefore, the information processing apparatus and the control method for the apparatus according to the present invention can eliminate the state where the designated position and the locator are separated from each other regardless of the relative relationship between the designated position and the position of the locator. Thereby, the information processing apparatus and the control method for the apparatus according to the present invention can easily specify the time that the user has made the progress, and can further improve the convenience of the user when outputting the content.

In the information processing apparatus of the present invention,
(1) The setting means sets the interlocking ratio by substituting a predetermined value for the ratio at which the user's operation and the movement of the locator are interlocked.

  According to said structure (1), the said information processing apparatus sets the said ratio which interlock | cooperates by substituting a predetermined value for the ratio which a user's operation and the movement of a locator interlock | cooperate. That is, the information processing apparatus sets the ratio to a predetermined value.

  Therefore, the information processing apparatus of the present invention makes it easy for the user to specify the time for which the progress has been made, and can further improve the convenience of the user when outputting the content.

The output device of the present invention is
(1) An output device for outputting content,
(2) calculation means for calculating a time during which the output of the content has progressed from the position of the locator in the seek bar sent from the information processing apparatus;
(3) An output means for outputting the content from the time calculated by the calculation means is provided.

  According to said structure (1)-(3), the said output apparatus calculates the time which advanced the output of the content from the position of the locator in the seek bar sent from the said information processing apparatus. Then, the output device outputs the content from the calculated time.

  Therefore, the output device of the present invention makes it easy for the user to specify the time for which the progress has been made, and can improve the convenience of the user when outputting the content.

The electronic device of the present invention is
(1) An electronic device having an input surface capable of detecting a position designated by a user operation,
(2) the information processing apparatus;
(3) The output device is included.

  Therefore, the electronic apparatus of the present invention has the same effect as the information processing apparatus or the output apparatus.

  The information processing apparatus may be realized by a computer. In this case, a control program for causing the information processing apparatus to be realized by the computer by operating the computer as each unit of the information processing apparatus, and a computer-readable recording medium on which the control program is recorded fall within the scope of the present invention. .

  As described above, when a user operation is detected at an arbitrary position on the input surface, the information processing apparatus according to the present invention is configured so that the first designated position detected by the input surface and the user operation are the input. An acquisition means for acquiring a length of a trajectory connecting the second designated position further detected by moving along the surface, and the length of the trajectory acquired by the acquisition means has a predetermined threshold value. Detecting means for detecting that the position is above, and determining means for determining whether or not the second designated position is coincident with the position of the locator when it is detected that the detecting means is exceeding If the determination means determines that they do not match, the setting means for setting a ratio at which the user operation and the movement of the locator are linked, and the length of the trajectory acquired by the acquisition means Sending out the position in the seek bar that can be calculated from the ratio set by the setting means and in the direction toward the second designated position as the position of the locator moved by the user operation And means.

  Further, according to the control method of the information processing device of the present invention, when a user operation is detected at an arbitrary position on the input surface, the first designated position detected by the input surface and the user operation are the input An acquisition step of acquiring a length of a trajectory connecting the second designated position further detected by moving along the surface, and the length of the trajectory acquired in the acquisition step is a predetermined threshold value.

  The embodiment of the present invention will be described in detail with reference to FIGS.

[Configuration of Smartphone 100]
Based on FIG. 1, the structure of the smart phone 100 is demonstrated. FIG. 1 is a block diagram illustrating a main configuration of the smartphone 100.

  The smartphone (electronic device) 100 is an electronic device including an input surface 41 that can detect a position specified by a user operation (user operation) 4a. A function equivalent to the smartphone 100 can be realized by a mobile phone, a personal computer, a tablet terminal, or the like. That is, as long as the electronic device includes an input surface 41 that can detect a position designated by a user operation and can input and output necessary information, the electronic device can be realized without being a smartphone.

  The smartphone 100 includes an input unit 40 (input surface 41, input control unit 42), a control unit 11 (length acquisition unit 12, length detection unit 16, coincidence determination unit 17, ratio setting unit 14, position sending unit 15), A display unit 70 (display control unit 71, display surface 72) and a storage unit 30 are included.

  Note that, from the viewpoint of ensuring the simplicity of the description, portions not directly related to the present embodiment are omitted from the description of the configuration and the block diagram. However, the smartphone 100 may include the omitted configuration in accordance with the actual situation. Moreover, in this Embodiment, although the control part 11 and the display part 70 are shown in FIG. 1 as an apparatus incorporated in the smart phone 100, these are the external apparatuses connected so that communication was possible outside the smart phone 100. May be.

(Input unit 40)
The input unit 40 receives a user operation 4a. The input unit 40 includes an input surface 41 and an input control unit 42.

  The input surface 41 outputs, to the input control unit 42, two-dimensional coordinate information 9a on the input surface of the user's finger that has touched the input surface. In the present embodiment, it is preferable that the input surface 41 is realized by a touch panel. However, the type of hardware is not limited to the touch panel as long as the input surface 41 is an input device that can detect a contact position by a user operation.

  Note that the user can use an indicator such as a stylus instead of a finger to give input to the smartphone 100. That is, in the above, “user's finger” includes “indicator such as stylus”. In the above description, “the user touches the input surface with a finger” is described. However, when the input surface 41 is, for example, a touch panel that can detect the proximity of the finger, the smartphone 100 may It is possible to operate in the same manner as in the case of contact by detecting proximity.

  The input control unit 42 detects the locus 4b of the user operation 4a with respect to the input surface 41. That is, the input control unit 42 receives the coordinate information 9a of the position on the input surface 41 specified by the user by dragging the locator 7 displayed on the input surface 41 with a finger from the input surface. Get at time interval.

  Here, the “drag” refers to an operation of moving the user to slide his / her finger on the input surface. Further, a position acquired at a certain timing is designated as a designated position (first designated position) 5a, and a position obtained at the next timing is designated as a designated position (second designated position) 5b. Then, the input control unit 42 outputs the locus 4b connecting the designated position 5a and the designated position 5b to the length acquisition unit 12 of the control unit 11.

(Control unit 11)
The control unit (information processing apparatus) 11 includes a seek bar 6 indicating the progress of the output of the content 8 by the display unit 70 as the locator 7 moves, and sends the position of the locator 7 in the seek bar, thereby displaying the display unit 70. Can specify the time during which the output of the content 8 has progressed.

  Here, the content 8 includes a television program broadcast from a broadcasting station. The content 8 includes all video, images, music, audio, text, characters, formulas, numbers, symbols provided from, for example, cable TV, CS broadcast, radio broadcast, DVD (Digital Versatile Disk), and the Internet. .

  The “progressed time” refers to the time (elapsed time) spent when the display unit 70 displays the content 8 without interruption from the beginning. For example, when the content 8 is a moving image, it is generally referred to as “playback position”, but in order to avoid confusion with the “position” of the locator 7 and the “position” on the input surface specified by the user operation 4a, Then, it is referred to as “the time when (the output from the beginning of the content 8 is advanced)” or “the progress time” (that is, “the time”, not “the position”).

  Each function of the control unit 11 may be realized by a CPU (Central Processing Unit) executing a program stored in a storage element such as a RAM (Random Access Memory) or a flash memory. The control unit 11 includes a length acquisition unit 12, a length detection unit 16, a coincidence determination unit 17, a ratio setting unit 14, and a position sending unit 15.

  When the user operation 4a is detected at an arbitrary position on the input surface 41, the length acquisition unit (acquisition means) 12 detects the designated position 5a detected by the input surface and the user operation 4a along the input surface. The length 2 of the locus 4b connecting to the designated position 5b further detected by moving is acquired.

  Specifically, the length acquisition unit 12 calculates the length 2 of the trajectory 4b input from the input control unit 42, and uses the calculated length 2 as the ratio setting unit 14, the position sending unit 15, and the length detection. To the unit 16. Here, since the length 2 is the distance between the two pieces of coordinate information 9a (designated position 5a and designated position 5b) input from the input control unit 42 at predetermined time intervals, the length is designated by the user along the input surface. Note that this is equivalent to moving the position.

  The length acquisition unit 12 calculates, for example, the Euclidean distance (the square root of the sum of the square of the horizontal distance between two points and the square of the vertical distance) on the input surface between the designated position 5a and the designated position 5b. It may be calculated as 2. In particular, when the locator 7 moves only in the horizontal direction, the length acquisition unit 12 determines the difference (B−A) between the horizontal coordinate (A) of the designated position 5a and the horizontal coordinate (B) of the designated position 5b. ) Can be calculated as length 2. The unit of length 2 may be anything, for example, a dot, pixel, point, centimeter, or the like.

  The length detection unit (detection means) 16 determines whether or not the length 2 of the locus 4b acquired by the length acquisition unit 12 is below a predetermined threshold value. In other words, the length detection unit 16 determines whether or not the user is slowly moving the designated position. In addition, the movement speed when it is determined that the user is moving the specified position slowly is “slow speed”, and the movement speed when the user is determined not to move the specified position slowly is “standard speed”. "

  Specifically, when the length 2 is input from the length acquisition unit 12, the length detection unit 16 compares the length with a predetermined threshold value. Then, when the length is smaller than the predetermined threshold, the length detection unit 16 outputs a determination result 9c indicating that the length 2 is below the predetermined threshold to the ratio setting unit 14. To do.

  That is, assuming that length 2 is dx and the predetermined threshold value is nsp, the length detection unit 16 determines “slow speed” when −nsp <dx <nsp is satisfied, and dx ≦ −nsp or nsp When ≦ dx is satisfied, it is determined as “standard speed”. The determination result 9c may be a 1-bit flag, for example.

  In addition, the length detection unit 16 detects that the length 2 of the locus 4b acquired by the length acquisition unit 12 exceeds the predetermined threshold value. In other words, the length detection unit 16 detects that the user has switched from the state where the position of the locator 7 is moved at “slow speed” to the state where the position of the locator 7 is moved at “standard speed”. To do.

  Specifically, the length detection unit 16 determines that the length 2 is not less than the predetermined threshold value by the same process as described above, so that the length exceeds the predetermined threshold value. Detect that Then, the length detection unit 16 outputs a determination result 9c indicating that the length 2 exceeds a predetermined threshold value to the coincidence determination unit 17.

  The coincidence determination unit (determination means) 17 determines whether or not the designated position 5b and the position of the locator 7 coincide with each other when it is detected that the length detection unit 16 exceeds the position.

  Specifically, when a determination result 9c indicating that a predetermined threshold value is exceeded is input from the length detection unit 16, the coincidence determination unit 17 determines whether the specified position 5b on the input surface 41 and the display surface 72 It is determined whether or not the display position of the locator 7 matches. When it is determined that they match, the match determination unit 17 outputs a determination result 9d indicating that both match to the ratio setting unit 14.

  The ratio setting unit (setting unit) 14 sets the ratio 3 in which the user operation 4a and the movement of the locator 7 are interlocked according to the length 2 of the locus 4b acquired by the length acquisition unit 12.

  Specifically, the ratio setting unit 14 determines whether the determination result 9c indicating that the value is below a predetermined threshold is input from the length detection unit 16, or the designated position 5b and the display position of the locator 7 are When the determination result 9 d indicating that they match is input from the match determination unit 17, the ratio 3 is set according to the length 2 input from the length acquisition unit 12, and the ratio is sent to the position sending unit 15. Output.

  Here, the ratio setting unit 14 sets the interlocked ratio by substituting a predetermined value (this value will be described in detail later) into the ratio 3 in which the user operation 4a and the movement of the locator 7 are interlocked. To do.

  Alternatively, the ratio setting unit 14 may set the ratio 3 so as to be proportional to the length 2 of the locus 4b acquired by the length acquisition unit 12. Furthermore, the ratio setting unit 14 may set the ratio so that the locator position 1 calculated from the length 2 and the ratio 3 of the trajectory 4b matches the designated position 5b.

  The position sending unit (sending means) 15 is a position in the seek bar 6 that can be calculated from the length 2 of the locus 4b acquired by the length acquiring unit 12 and the ratio 3 set by the ratio setting unit 14. The position in the direction toward the position 5b is sent as the position of the locator 7 moved by the user operation 4a.

  Specifically, the position sending unit 15 sets the current locator 7 in the seek bar 6 by the amount of movement obtained by multiplying the length 2 input from the length acquisition unit 12 by the ratio 3 input from the ratio setting unit 14. The position obtained by moving the locator from the position in the direction toward the designated position 5 b is output to the display control unit 71 of the display unit 70.

  In addition, when the length detection unit 16 determines that the length 2 exceeds a predetermined threshold value, the match determination unit 17 determines that the designated position 5b and the position of the locator 7 match. In this case, the position sending unit 15 may output the position where the locator is moved from the current position of the locator 7 on the seek bar 6 by the amount of movement equal to the length 2 to the display control unit 71 of the display unit 70. . The processing executed by the position sending unit 15 will be described in detail later.

(Display unit 70)
The display unit (output device) 70 outputs the content 8. Note that each function of the display unit 70 may also be realized by the CPU executing a program stored in a storage element such as a RAM or a flash memory. The display unit 70 includes a display control unit 71 and a display surface 72.

  The display control unit (calculation unit, output unit) 71 calculates the time during which the output of the content 8 has progressed from the position of the locator 7 in the seek bar 6 sent from the position sending unit 15 of the control unit 11. Then, the display control unit 71 outputs the display data 9b to the display surface 72 so that the content 8 can be displayed on the display surface 72 from the calculated time. Here, the display data 9b may be, for example, an image in a bitmap format, an image according to another format, or another data format suitable for display.

  The display surface 72 displays the display data 9b input from the display control unit 71. In this embodiment, a liquid crystal display (LCD) is mainly assumed. However, the type of hardware is not limited as long as the device has a display function (particularly, a flat panel display). For example, an apparatus including a display element such as a plasma display panel (PDP) or an EL (Electroluminescence) display, and a driver circuit that drives the display element based on display data 9b input from the display control unit 71 Thus, the display surface 72 can be configured.

  In addition, in order to clarify the function which each structure has, FIG. 1 shows the input surface 41 and the display surface 72 separately. However, for example, when the input surface 41 is realized by a touch panel and the display surface 72 is realized by a liquid crystal display, the two may be configured integrally (see FIG. 2).

  In this case, the input surface 41 is composed of a transparent transmissive member (for example, glass) formed in a rectangular plate shape, and is integrally formed so as to cover the display surface 72. Thereby, since the contact position of the user's finger with respect to the input surface 41 and the display position of the figure or the like displayed on the display surface 72 according to the contact match, the user can obtain a natural input feeling.

  The storage unit 30 is a storage device that can store the content 8. The storage unit 30 can be constituted by, for example, a hard disk, a semiconductor memory, a DVD, or the like. In addition, in this Embodiment, although the memory | storage part 30 is shown in FIG. 1 as an apparatus incorporated in the smart phone 100, the external storage device connected to the exterior of the smart phone 100 so that communication was possible may be sufficient.

[Calculation method of ratio 3]
As described above, the ratio setting unit 14 sets the ratio 3 in which the user operation 4a and the movement of the locator 7 are interlocked according to the length 2 of the locus 4b acquired by the length acquisition unit 12.

  For example, when the length detection unit 16 determines that the length 2 is below a predetermined threshold, the ratio setting unit 14 sets the predetermined ratio 3 to the ratio 3 at which the user operation 4a and the movement of the locator 7 are interlocked. By substituting a value, the linked ratio is set. That is, in the example in which the length 2 is 5 pixels and the predetermined threshold is 10 pixels, the length 2 is below the predetermined threshold, so the ratio setting unit 14 sets the ratio 3 to 0. An arbitrary real number (for example, 0.5) that is larger than 1 is set.

  Alternatively, the ratio setting unit 14 determines that the ratio 3 is proportional to the length 2 of the trajectory 4b acquired by the length acquisition unit 12, regardless of whether the length 2 is below a predetermined threshold value. May be set. For example, the ratio setting unit 14 sets the ratio 3 to 1 when the length 2 is 10 pixels, sets the ratio 3 to 0.8 when the length 2 is 8 pixels, and sets the ratio 3 when the length 2 is 5 pixels. 3 may be set to 0.5.

  Alternatively, the ratio setting unit 14 may set the ratio 3 so that the movement amount 5c obtained by multiplying the length 2 by the ratio 3 always becomes a constant value.

[Method for determining locator position 1]
A method for determining the locator position 1 by the position sending unit 15 will be described with reference to FIG. FIG. 2 is a schematic diagram schematically showing the operation of the smartphone 100.

  As described above, the position sending unit 15 sets the current position of the locator 7 by the movement amount 5c obtained by multiplying the length 2 input from the length acquisition unit 12 by the ratio 3 input from the ratio setting unit 14. The position (position of locator 7b) where the locator is moved from (position of locator 7a in FIG. 2) is determined as a new locator position 1.

  That is, assuming that the length 2 of the locus 4b connecting the designated position 5a and the designated position 5b is dx and the ratio 3 set by the ratio setting unit 14 is β, the position sending unit 15 moves the movement amount represented by L. 5c is calculated as L = dx × β, and the position of the locator 7b (locator position 1) obtained by moving the locator 7a by the moving amount is output to the display control unit 71 of the display unit 70.

  As shown in FIG. 2, when β is set to an arbitrary real number larger than 0 and smaller than 1, the locator 7 is more than the distance (length 2) by which the user has moved the designated position along the input surface 41. Move a short distance (move slowly). For example, when the ratio 3 is set to 0.5, the half length of the length 2 is calculated as the movement amount 5c, and the locator 7 moves by the half length.

  That is, when the user slowly moves the finger in contact with the input surface 41, the locator 7 slowly moves on the seek bar 6 so that the time for which the output of the content 8 has progressed can be easily specified.

  In the above example, the movement amount 5c is proportional to the length 2 (L = dx × β), but may be proportional to the square of the length 2 (L = dx ^ 2 × β).

[How to determine locator position 1 after slowly releasing the speed]
Based on FIG. 3, the operation of the smartphone 100 when the user switches from the state in which the position of the locator 7 is moved at “slow speed” to the state in which the position of the locator 7 is moved at “standard speed”. Will be explained. FIG. 3 is a schematic diagram schematically showing different operations of the smartphone 100, and FIG. 3A is a direction from the designated position 5 a toward the designated position 5 b (advancing direction of the user's finger in contact with the input surface 41). The case where the movement of the locator 7 is delayed is shown, and (b) shows the case where the movement of the locator 7 is progressing in the direction from the designated position 5a toward the designated position 5b.

  As shown in FIG. 3, in the state where the position of the locator 7 is moved at “slow speed” by slowly moving the finger that is in contact with the input surface 41 by the user, the designated position 5b and the position of the locator 7b are Deviation. From this state, when the user moves the finger touching the input surface 41 at a normal speed to switch to the state where the position of the locator 7 is moved at the “standard speed”, when the divergence continues, The user feels uncomfortable in operation.

  Therefore, when the length detection unit 16 detects that the above state has been switched, if the designated position 5b and the position of the locator 7b are deviated, the smartphone 100 follows the designated position 5b. As shown in FIG. 3 (a), the locator position 1 is set so that the designated position 5b can follow the locator 7b (FIG. 3 (b)).

  As illustrated in FIG. 3A, when the movement of the locator 7 is delayed with respect to the direction from the designated position 5a to the designated position 5b, the smartphone 100 (ratio setting unit 14) sets the ratio 3 (β). By setting the value to 1.0 or more and increasing the moving amount 5c of the locator 7, the position of the locator 7b follows the designated position 5b.

  As shown in FIG. 3B, when the locator 7 is moving in the direction from the designated position 5a to the designated position 5b, the smartphone 100 (ratio setting unit 14) sets the ratio 3 (β). By setting the value to 1.0 or less and reducing the moving amount 5c of the locator 7, the designated position 5b can follow the position of the locator 7.

[Processes executed by the smartphone 100]
Based on FIG. 4, the flow of the process which the smart phone 100 performs is demonstrated. FIG. 4 is a flowchart illustrating an example of processing executed by the smartphone 100. In the following description, parenthesized “˜step” represents each step of the control method.

  When the input surface 41 detects the user operation 4a (step 1: abbreviated as S1), the input control unit 42 acquires the locus 4b of the user operation (S2).

  The length acquisition unit 12 acquires the length 2 of the locus 4b (S3, acquisition step). The length detector 16 determines whether or not the length 2 is below a predetermined threshold (S4). When it is determined that the ratio is lower (YES in S4), the ratio setting unit 14 sets the ratio 3 to a predetermined value according to the length 2 (S5a). Then, the position sending unit 15 calculates a movement amount L that can be calculated from the length 2 and the ratio 3 (S6a).

  On the other hand, when it is determined that the length exceeds the predetermined threshold by determining that the length is not lower (NO in S4, detection step), the coincidence determination unit 17 determines that the specified position 5b It is determined whether or not the position of the locator 7 matches (S7, determination step). When it is determined that they match (YES in S7), the position sending unit 15 calculates a movement amount L equal to the length 2 (S6b).

  On the other hand, if it is determined that they do not match (NO in S7), match determination unit 17 further determines whether or not locator 7 is delayed with respect to the direction of the user's finger (S8). When it is determined that it is delayed (YES in S8), the ratio setting unit 14 sets a value corresponding to the length 2 and 1 or more (S5b, setting step), and the position sending unit 15 sets the length. The movement amount L that can be calculated from 2 and the ratio 3 is calculated (S6c).

  On the other hand, when it is determined that there is no delay (NO in S8), the ratio setting unit 14 sets a value corresponding to the length 2 and 1 or less (S5c, setting step), and the position sending unit 15 A movement amount L that can be calculated from the length 2 and the ratio 3 is calculated (S6d).

  Then, the position sending unit 15 sends the position of the locator 7b moved by the movement amount L from the current position of the locator 7a as the position of the locator 7 moved by the user operation 4a (S9, sending step). The display control unit 71 outputs the content 8 from the time when the output of the content specified by the locator position 1 sent from the position sending unit 15 has progressed (S10).

[Effects of smartphone 100]
Since the smartphone 100 can eliminate the state where the designated position 5b and the locator 7 are separated from each other, the user does not feel uncomfortable in operation. Thereby, the smartphone 100 has an effect that it is easy to specify the time that the user has made progress, and the convenience of the user when the content 8 is output can be improved.

  As described above, according to the related art, the problem that it is difficult to specify the time that the user has made cannot be reliably solved, or another problem is solved as the problem is solved. Arise. For example, when a plurality of interfaces are mixed, the operation for finely adjusting the position of the locator becomes complicated, or the user has difficulty in understanding the relationship between the distance to which the finger is moved and the position of the locator.

  On the other hand, according to the smartphone 100, since only a unified interface for adjusting the position of the locator 7 is provided to the user, there is an effect that the operation is not complicated. In addition, since the scale width of the seek bar 6 remains uniform, the user can easily understand the relationship between the distance to which the finger is moved and the position of the locator 7.
