Description

  The present invention relates to an information processing apparatus and the like that can specify a time during which an output device has advanced the output of content by sending the position of a slider on a seek bar.

  When a user outputs a desired part of content to an electronic device, it is common to specify a time during which the output of the content has progressed (a time spent when the output device outputs the content without interruption from the beginning) It is.

  Based on FIG. 10, an example in the case where a user performs the above-described designation in a conventional electronic device will be described. FIG. 10 is a schematic diagram showing a state in which the user specifies the time during which the output of the content has progressed by moving the slider 7 of the seek bar 6 displayed on the conventional electronic device left and right.

  As shown in FIG. 10, in an information terminal such as a so-called smart phone, some home-use game machines, or a personal computer, a seek bar 6 indicates the progress of output of content by an electronic device as the slider 7 moves. Is displayed. The user designates the advanced time by operating the slider 7 in the seek bar.

  Interfaces for performing the above operations have been extensively studied. For example, Patent Document 1 below discloses a program that gives a user a unified operational feeling in a user interface for controlling playback of time-series data, regardless of the length of playback time of the entire time-series data. Yes.

  Patent Document 3 below discloses an information processing apparatus capable of finely adjusting display information by an easy scrolling operation on information displayed on a screen. Further, Patent Document 4 below discloses a portable terminal that can be easily input by simply moving the thumb while the user holds the portable terminal in a portable terminal having a touch screen. Yes.

JP 2008-33743 A (published February 14, 2008) JP 2009-17486 A (released on January 22, 2009) JP 2009-295147 A (released on December 17, 2009) Special table 2010-538350 gazette (released on December 9, 2010)

  Based on FIG. 11, the problem of the conventional electronic device will be described in detail. FIG. 11 is a schematic diagram showing a relationship of variables necessary for calculation for moving the slider 7 in the seek bar 6 displayed on the conventional electronic device.

  As shown in FIG. 11, 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 slider 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, if 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 slider 7 is b = 0. The user must operate the slider so as to move by a minute distance of .0017 m (1.7 mm). According to the ability of the input device to detect the operation and the accuracy of human operation, it is almost impossible to perform the above operation (first problem).

  Further, as described above, in the conventional electronic device, the user designates the time for which the progress has been made by “operating the slider 7”. For example, since the portable electronic device shown in FIG. 10 displays the seek bar 6 superimposed on the limited display screen with the content, display of the content is hindered by the user's finger operating the slider 7. There is also (second problem).

  None of the prior arts described in Patent Documents 1 to 4 can simultaneously solve the above two problems that occur in conventional electronic devices. For example, according to the information processing apparatus described in Patent Document 3, since the user can finely designate the progress time by operating the “second scroll bar”, the first problem can be solved. . However, in the information processing apparatus, since the user needs to directly operate the slider, the second problem cannot be solved.

  The present invention has been made in view of the above problems, and an object of the present invention is to improve the convenience of the user at the time of content output by simultaneously solving the first problem and the second problem. It is providing the information processing apparatus etc. which can be used.

In order to solve the above problems, an information processing apparatus according to the present invention provides:
(1) The output device is provided with a seek bar indicating the progress of output of content by moving the slider, and the position of the output device progressing output of the content can be specified by sending the position of the slider in the seek bar Information processing apparatus,
(2) when a user operation is detected at an arbitrary position on the input surface, a first acquisition unit that acquires a length of a trajectory connecting a position at which the user operation is started and a position at which the user operation is ended;
(3) second acquisition means for acquiring an angle formed by the locus with respect to a predetermined reference line when a user operation is detected at an arbitrary position on the input surface;
(4) setting means for setting a ratio at which the user's operation and the movement of the slider are interlocked according to an angle made by the second acquisition means;
(5) Sending means for sending the position on the seek bar that can be calculated from the ratio set by the setting means and the length obtained by the first obtaining means as the position of the slider moved by the user's operation. It is characterized by having.

In addition, in order to solve the above-described problem, the control method of the information processing apparatus of the present invention
(1) The output device is provided with a seek bar indicating the progress of output of content by moving the slider, and the position of the output device progressing output of the content can be specified by sending the position of the slider in the seek bar A method for controlling an information processing apparatus,
(2) when a user operation is detected at an arbitrary position on the input surface, a first acquisition step of acquiring a length of a trajectory connecting a position at which the user operation is started and a position at which the user operation is ended;
(3) a second acquisition step of acquiring an angle formed by the trajectory with respect to a predetermined reference line when a user operation is detected at an arbitrary position on the input surface;
(4) a setting step for setting a ratio at which the user's operation and the movement of the slider are interlocked according to the angle made in the second acquisition step;
(5) Sending out the position on the seek bar that can be calculated from the ratio set in the setting step and the length acquired in the first acquisition step as the position of the slider moved by the user's operation And a step.

  According to said structure, the information processing apparatus of this invention and the control method of the said apparatus can detect that the user's operation for moving a slider was started in the arbitrary positions in an input surface. In other words, the information processing apparatus or the like can cause the user to operate the slider on the seek bar at an arbitrary position on the input surface. Thereby, since the display of content is not obstructed by the user's finger operating the slider, the information processing apparatus and the like can solve the second problem.

  In addition, the information processing apparatus or the like acquires the length of a trajectory connecting a position where the user's operation is started and a position where the user's operation is ended, and acquires an angle formed by the trajectory with respect to a predetermined reference line. Then, the information processing apparatus or the like sets a ratio at which the user's operation and the movement of the slider are interlocked according to the angle formed, and determines the position on the seek bar that can be calculated from the ratio and the length of the trajectory. It can be sent as the position of the slider moved by the operation of.

  That is, the information processing apparatus or the like can allow the user to specify the time for progressing depending on not only the remaining time of the content and the length of the trajectory but also the angle formed. In other words, the information processing apparatus or the like can solve the first problem because the number of parameters is increased as compared with the conventional one and the user is allowed to specify the time for the progress.

  Therefore, the information processing apparatus and the control method for the apparatus according to the present invention can solve the first problem and the second problem at the same time, thereby improving the convenience for the user when outputting the content.

In the information processing apparatus of the present invention,
(1) The setting means sets the interlocking ratio so as to be inversely proportional to the angle formed by the second acquisition means.

  According to the above configuration, the information processing apparatus sets the interlocking ratio to be smaller as the angle formed is larger. That is, the information processing apparatus moves the slider small even when the length of the locus is long (even when the user gives a large operation). Therefore, even when the remaining time of content is long, the user can specify the advanced time in detail.

  On the other hand, the information processing apparatus sets a larger interlocking ratio as the angle formed is smaller. That is, the information processing apparatus moves the slider largely even if the length of the locus is short (even if the user gives a small operation). Therefore, even when the remaining time of the content is long, the user can specify a large time for the progress by a few operations.

  Therefore, the information processing apparatus of the present invention can further improve the convenience of the user when outputting content.

In the information processing apparatus of the present invention,
(1) The setting unit outputs the maximum value of the time during which the output of the content can be advanced by the user's operation and the angle obtained by the second acquisition unit and the output device outputs the content. It is calculated from the remaining time, and the interlocking ratio is set as a ratio between the maximum value and the remaining time.

  According to said structure, the said information processing apparatus calculates the maximum value of the time which can advance the output of a content based on the angle | corner and the remaining time of a content. The information processing apparatus sets the interlocking ratio as a ratio between the maximum value and the remaining time.

  Therefore, the information processing apparatus of the present invention can further improve the convenience of the user when outputting content.

In the information processing apparatus of the present invention,
(1) When the angle made by the second obtaining unit exceeds a predetermined limit angle, the setting unit calculates the predetermined limit value as the maximum value, thereby calculating the interlocking ratio. It is characterized by setting.

  According to the above configuration, when the acquired angle exceeds a predetermined limit angle, the information processing apparatus sets the interlocked ratio by calculating a predetermined limit value as the maximum value. . Thereby, the information processing apparatus can prevent a user's erroneous operation.

  Therefore, the information processing apparatus of the present invention can further improve the convenience of the user when outputting content.

The output device of the present invention is
(1) An output device for outputting content,
(2) calculation means for calculating the time for which the output of the content has progressed from the position of the slider 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, the said output device can calculate the time which advanced the output of content from the position of the slider in the seek bar sent out from the said information processing apparatus, and can output a content from the said time.

  Therefore, the output device of the present invention can further improve the convenience of the user when outputting 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 device of the present invention can further improve the convenience for the user when outputting content.

  The information processing apparatus and the output apparatus may be realized by a computer. In this case, by causing the computer to operate as each unit of the information processing device or the output device, a control program that causes the information processing device or the output device to be realized by the computer, and a computer-readable recording that records the control program Media are also 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 has a length of a trajectory connecting a position where the user operation is started and a position where the user operation is ended. A second acquisition unit that acquires an angle formed by the trajectory with respect to a predetermined reference line when a user operation is detected at an arbitrary position on the input surface; A setting unit that sets a ratio in which the user's operation and the movement of the slider are interlocked according to an angle made by the second acquisition unit, a ratio set by the setting unit, and the first acquisition Sending means for sending the position on the seek bar that can be calculated from the length acquired by the means as the position of the slider moved by the user's operation.

  Further, according to the control method of the information processing apparatus of the present invention, when a user operation is detected at an arbitrary position on the input surface, the length of the locus connecting the position where the user operation is started and the position where the user operation is ended is A second acquisition step of acquiring an angle formed by the trajectory with respect to a predetermined reference line when a user operation is detected at an arbitrary position on the input surface; A setting step for setting a ratio in which the user's operation and the movement of the slider are linked in accordance with the angle made in the second acquisition step; the ratio set in the setting step; and the first A sending step for sending the position on the seek bar that can be calculated from the length obtained in the obtaining step as the position of the slider moved by the user operation; It is a non-configuration.

  Based on FIGS. 1-9, embodiment of this invention is described in detail.

  Hereinafter, in order to clearly indicate that there are a plurality of members, the members may be indicated by further adding a or b to the same member number. For example, “slider 7a”, “slider 7b”, and the like are shown. Moreover, a and b further attached to the member number of the member may be omitted, and the member may be generically named. For example, the slider 7a and the slider 7b may be collectively referred to as “slider 7”.

  In the following description and the above drawings, description will be made on the assumption that the user holds the smartphone 100 (see FIG. 1) with the left hand and makes the index finger of the right hand contact the input surface. However, the hand that holds and operates the smartphone 100 may be the right hand or the left hand, and the finger that contacts the input surface may be a finger other than the index finger.

  In addition, the user can use an indicator such as a stylus instead of a finger to operate the smartphone 100. That is, in the following description, “user's finger” includes “indicator such as stylus”. However, in order to ensure the simplicity of description, only “user's finger” is described below.

  Furthermore, in the following description and the above-mentioned drawings, it is described as “the user makes a finger touch the input surface”. However, when the input surface included in the input unit 40 is, for example, a touch panel that can detect the proximity of a finger, the smartphone 100 can detect the proximity of the user's finger to the input surface, as in the case of contact. It is possible to operate.

[Outline of Smartphone 100, Information Processing Device 11, and Output Device 12]
An outline of the smartphone 100 will be described based on FIG. FIG. 1 is a block diagram illustrating a main configuration of the smartphone 100.

  A smartphone (electronic device) 100 is an electronic device that includes an information processing device 11 and an output device 12 and includes an input unit (input surface) 40 that can detect a position designated by a user operation.

  In addition, in order to clarify the function which each structure has, FIG. 1 has shown the input part 40 and the display part 70 separately. However, for example, when the input unit 40 is realized by a touch panel and the display unit 70 is realized by a liquid crystal display, the two may be configured integrally (see, for example, FIG. 2 or FIG. 3).

  The information processing apparatus 11 includes a seek bar 6 indicating the progress of output of the content 2 by the output device 12 as the slider 7 moves, and sends out the slider position (slider position) 1 in the seek bar. Is a device that can specify the time during which the output of the content 2 has progressed.

  Here, the “content” includes a television program broadcast from a broadcasting station (including both a main channel and a sub-channel). “Content” includes, for example, all images, images, music, audio, text, characters, formulas, numbers, symbols provided from cable TV, CS broadcast, radio broadcast, DVD (Digital Versatile Disk), the Internet, etc. Including.

  The “progressed time” refers to the time (elapsed time) that is spent when the output device 12 outputs the content 2 without interruption from the beginning. When the content 2 is a moving image, it is generally referred to as a “playback position” or the like. However, in order to avoid confusion with the “position” of the slider 7 and the “position” on the input surface specified by the user operation 3, hereinafter “ “Time when progress is made from the beginning of the content 2” or “progress time” (ie, “time” instead of “position”).

  The output device 12 is a device that includes a display control unit (output unit) 60 that outputs the content 2 from the advanced time specified by the position of the slider 7 sent from the information processing device 11.

  In the present embodiment, the information processing device 11 and the output device 12 are shown in FIG. 1 as devices built in the smartphone 100, but the information processing device 11 or the output device 12 communicates outside the smartphone 100. It may be an external device connected as possible.

  Based on FIG. 2 and FIG. 3, the basic operation of the information processing apparatus 11 will be outlined. FIG. 2 is a schematic diagram showing a state in which the user moves the slider 7 by a user operation 3 that determines the end position 8b in the upper right direction from the start position 8a. FIG. 3 is a schematic diagram showing a state in which the user moves the slider 7 by a user operation 3 that determines the end position 8b in the lower right direction from the start position 8a.

  As shown in FIGS. 2 and 3, the user can start a user operation (user operation) 3 for moving the slider 7 at an arbitrary position on the input unit 40 (input surface). That is, the information processing apparatus 11 detects that the user operation is started at an arbitrary position on the input surface of the smartphone 100 (it is not necessary to bring the finger into contact with the slider 7). Thereby, since the user can operate the slider 7 at a position where the content 2 is not obstructed, the information processing apparatus 11 can solve the second problem.

  The information processing apparatus 11 acquires the distance (length) 10 of the locus 9 connecting the start position (start position) 8a and the end position (end position) 8b of the user operation. In addition, the information processing apparatus 11 acquires an angle (an angle formed) 4 of the locus 9 with respect to a predetermined reference line.

  The information processing apparatus 11 sets a ratio 5 at which the user operation 3 and the movement of the slider 7 are interlocked according to the angle 4. The information processing apparatus 11 moves the slider 7 to a position on the seek bar 6 that can be calculated from the ratio 5 and the distance 10 (moved from the position of the slider 7a to the position of the slider 7b), and the moved position (slider position). 1) is sent to the output device 12.

  That is, the larger the angle 4 (the larger the positive direction as shown in FIG. 2), the smaller the ratio 5 is set, so the slider 7 becomes smaller even if the distance 10 is large (even if the user gives a large operation). Moving. Thereby, even when the remaining time of the content 2 is long, the user can specify the advanced time in detail.

  On the other hand, the smaller the angle 4 is (the larger the negative direction is as shown in FIG. 3), the larger the ratio 5 is set. Therefore, even if the distance 10 is small (even if the user gives a small operation), the slider 7 Move a lot. As a result, even when the remaining time of the content 2 is long, the user can specify a large amount of time for the progress by a few operations.

  That is, the information processing apparatus 11 can allow the user to specify the progress time by depending not only on the remaining time and distance 10 of the content 2 but also on the angle 4 (increasing the number of parameters as compared with the conventional method). Thereby, the information processing apparatus 11 can solve the first problem.

  As described above, the information processing apparatus 11 sets the ratio 5 so as to be inversely proportional to the angle 4. However, this setting is only an example. For example, the information processing apparatus 11 may set the ratio 5 so as to be proportional to the angle 4.

  2, 3, and the above description, the user moves the slider 7 by the user operation 3 that determines the end position 8 b in the upper right (or lower right) direction from the start position 8 a, so that the user can output the content 2. An example in which the progress time is specified in the direction of advancing has been described.

  However, when the user moves the slider 7 by the user operation 3 that determines the end position 8b from the start position 8a in the upper left (or lower left) direction, the user can also specify the progress time in the direction in which the output of the content 2 can be returned. Note that you can.

  However, in order to avoid overlapping explanations, only the case where the progress time is specified in the direction in which the output is advanced will be described below (the process for specifying the direction in which the output is advanced is the same as the process in the case of specifying the direction in which the output is advanced) Is).

[Configuration of Smartphone 100]
Based on FIG. 1, the structure of the smart phone 100 (information processing apparatus 11, the output device 12) is demonstrated. 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.

  Hereinafter, the order of the input unit 40, the input control unit 50, the operation detection unit 14, the distance acquisition unit 15, the angle acquisition unit 16, the ratio setting unit 17, the position sending unit 18, the display control unit 60, the display unit 70, and the storage unit 30. The function which each structure bears is demonstrated.

  The input unit (input surface) 40 outputs two-dimensional coordinate information on the input surface of the user's finger that has touched the input surface to the input control unit 50. In the present embodiment, it is desirable to provide a touch panel capable of detecting multi-touch as the input unit 40 (that is, the “input surface” is included in the input unit 40). However, the type of hardware is not limited to the touch panel as long as the input unit 40 includes an input device that can detect a contact position by a user operation.

  The input control unit 50 detects the locus 9 of the user operation 3 with respect to the input surface of the input unit 40. For example, coordinate information is acquired from the input unit 40 at predetermined time intervals, and the series of coordinate data is output to the operation detection unit 14 as a locus 9.

  When the locus 9 is input from the input control unit 50, the operation detection unit (detection unit) 14 detects that the user operation 3 for moving the slider 7 has started at an arbitrary position on the input surface. When detecting that the operation has been started, the operation detection unit 14 outputs the locus 9 input from the input control unit 50 to the distance acquisition unit 15 and the angle acquisition unit 16.

  Note that the user can input to the information processing apparatus 11 (operation detection unit 14) to start the user operation 3 for moving the slider 7 by, for example, an operation of pressing and holding the input surface. The operation may be an operation of tapping the input surface a predetermined number of times or an operation of pressing a predetermined key.

  When the trajectory 9 is input from the operation detection unit 14 (when the user operation 3 is detected at an arbitrary position on the input surface), the distance acquisition unit (first acquisition unit) 15 starts the user operation start position 8a. And the distance 10 of the trajectory 9 connecting the end position 8b. The distance acquisition unit 15 outputs the acquired distance 10 to the position sending unit 18.

  When the trajectory 9 is input from the operation detection unit 14 (when the user operation 3 is detected at an arbitrary position on the input surface), the angle acquisition unit (second acquisition unit) 16 determines the angle of the trajectory 9 with respect to the reference line. 4 is acquired. The angle acquisition unit 16 outputs the acquired angle 4 to the ratio setting unit 17.

  For example, as illustrated in FIG. 2, the reference line is set in parallel with the seek bar 6, but is not limited thereto. For example, the reference line may be set at an angle of 45 ° with respect to the seek bar 6.

  When the angle 4 is input from the angle acquisition unit 16, the ratio setting unit (setting unit) 17 sets the ratio 5 in which the user operation 3 and the movement of the slider 7 are interlocked according to the angle. The ratio setting unit 17 outputs the set ratio 5 to the position sending unit 18.

  The ratio setting unit 17 may set the ratio 5 so as to be inversely proportional to or proportional to the angle 4 acquired by the angle acquisition unit 16. Alternatively, the angle 4 acquired by the angle acquisition unit 16 and the output device 12 output the content 2 as the maximum value (adjustment time) of the time during which the output of the content 2 can be advanced by the user operation 3 (progress time). It may be calculated from the remaining time, and the ratio 5 may be set as the ratio between the adjustment time and the remaining time.

  The position sending unit (sending unit) 18 sets the position on the seek bar 6 that can be calculated from the ratio 5 and the distance 10 as the slider position 1 of the slider 7 moved by the user operation 3 to the display control unit 60 of the output device 12. Send it out.

  The display control unit (calculation means) 60 calculates the time during which the output of the content 2 has progressed from the slider position 1 of the slider 7 in the seek bar 6 sent from the position sending unit 18. Then, the display control unit (output unit) 60 outputs the content 2 from the calculated time.

  Further, the display control unit 60 outputs display data to the display unit 70 so that the slider 7 can be displayed on the display unit 70. The display data may be, for example, an image in a bitmap format, an image according to another format, or another data format suitable for display. In addition, the display control part 60 should just contain what can convert the format which should be displayed into the data for a display, for example, may be a general display adapter.

  The display unit 70 is a device that displays display data input from the display control unit 60 on a display surface. 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 input from the display control unit 60 Thus, the display unit 70 can be configured.

  As described above, when the input unit 40 is realized by a touch panel and the display unit 70 is realized by a liquid crystal display, both may be integrated. In this case, the input unit 40 includes an input surface made of a transparent transmissive member such as glass formed in a rectangular plate shape, and may be integrally formed so as to cover the display surface of the display unit 70. . Thereby, the contact position of the user's finger with respect to the input surface of the input unit 40 and the display position of the graphic or the like displayed on the display surface by the display unit 70 in accordance with the contact match, so the user has a natural input feeling. Can be obtained.

  The storage unit 30 is a non-volatile storage device that can store the content 2. 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.

[Movement method of slider 7]
A method for moving the slider 7 will be described with reference to FIG. FIG. 4 is a schematic diagram showing the relationship of variables necessary for calculation for the information processing apparatus 11 to move the slider 7.

(Calculation method of moving width of slider 7)
When the distance 10 of the trajectory 9 connecting the start position 8a and the end position 8b is a [m] and the angle 4 with respect to the reference line of the trajectory 9 is θ [°], the position sending unit 18 moves from the slider 7a to the slider 7b. The movement width S [m] is calculated as follows.

Here, R [seconds] represents the remaining time during which the output device 12 outputs the content 2. Further, f (θ, R) represents a ratio 5 at which the user operation and the movement of the slider 7 are interlocked when the user performs the user operation 3 at an angle θ when the remaining time of the content 2 is R. . As described above, the ratio f (θ, R) is set in the ratio setting unit 17.

  An upper limit value (limit angle) and a lower limit value (limit angle) may be set for the angle θ. That is, when the absolute value of the upper limit value and the lower limit value is M [°],

It may be. The absolute value M may be 45 ° or 60 °, for example. The absolute values may be different from each other in the upper limit value and the lower limit value.

  The position sending unit 18 obtains the slider position 1 (the position of the slider 7b) based on the position of the slider 7a and the movement width S calculated by the above [Equation 1]. The position sending unit 18 sends the slider position to the output device 12.

  The slider position 1 refers to the length from the left end of the seek bar 6 to the slider 7b. Alternatively, the slider position 1 may be a horizontal coordinate on the input surface of the slider 7. Further, the radius L [m] of the fan shown in FIG. 4 is preferably within a range in which the user can easily move the finger (for example, 0.03 to 0.08 m).

  That is, the distance acquisition unit 15 (first acquisition unit) may acquire the distance (length) 10 of the locus 9 when the distance (length) 10 of the locus 9 falls within a predetermined range. Thereby, the information processing apparatus 11 can further improve the convenience of the user when the content 2 is output.

(Calculation method of ratio 5)
The ratio setting unit 17 calculates the ratio f (θ, R) in the above [Equation 1] as follows.

Here, x (θ, R) [seconds] is the progress time of the content (the time when the output is advanced) when the user performs the user operation 3 at an angle θ when the remaining time of the content 2 is R. ) Is the maximum value of the time width that can be specified (adjustment time, maximum value of time during which content output can be advanced). For example, when the adjustment time x (θ, R) is calculated as 600 seconds, the user can specify the time that has been advanced from the output of the current content 2 in the range of 0 to 600 seconds.

  The adjustment time x (θ, R) is calculated as follows based on the angle θ and the remaining time R.

Here, r [second] is a lower limit value (limit value) of the adjustment time x (θ, R) when the angle θ takes the upper limit value M. r may be set arbitrarily in advance, or may be set depending on the remaining time R of the content 2. For example, when R is 300 seconds (5 minutes) or less, r = 60 seconds, when R is 3600 seconds (1 hour) or less, r = 300 seconds, and when R is 3600 seconds (1 hour) or more, r = R may be set, such as 600 seconds.

  That is, the ratio setting unit 17 (setting unit) sets the lower limit value (limit value) of the adjustment time x (θ, R) according to the remaining time R for outputting the content 2, and calculates the adjustment time. , Ratio (interlocking ratio) 5 may be set. Thereby, the information processing apparatus 11 can further improve the convenience of the user when the content 2 is output.

  When the angle θ takes the lower limit value −M, it can be easily calculated from the above equation that the adjustment time x (θ, R) takes the upper limit value (limit value) 2R−r. That is, the range of possible values of the adjustment time x (θ, R) is expressed as follows.

  The limit values (upper limit value and lower limit value) may be set to at least one of the angle θ and the adjustment time x (θ, R). That is, for example, when the angle acquisition unit 16 acquires an angle θ exceeding the upper limit value M, the upper limit value M may be set to the angle θ and the angle may be output to the ratio setting unit 17. Alternatively, when the adjustment time x (θ, R) is less than the lower limit value r due to the angle θ exceeding the upper limit value M, the ratio setting unit 17 sets r to the adjustment time x (θ, R), and the ratio f ( θ, R) may be calculated.

  The adjustment time x (θ, R) can also be calculated as follows.

The calculation of the adjustment time x (θ, R) according to the above [Equation 6] is essentially the same as the calculation according to the above [Equation 4].

(Progress time calculation method)
When the slider position 1 of the slider 7b sent from the position sending unit 18 is input, the display control unit 60 outputs the content 2 from the progress time specified by the slider position.

  That is, if the total length of the seek bar 6 is D [m] and the length from the end point of the seek bar 6 to the slider 7b (slider position 1) is d [m], the display control unit 60 sets the d / D of the content 2 to d / D. The content is output from the progress time corresponding to the ratio. This is equivalent to progressing and outputting the current content from the current content output for the time T [seconds] calculated below.

  Based on FIG. 5 and FIG. 6, the relationship among the angle θ, the adjustment time x (θ, R), and the ratio f (θ, R) will be described. FIG. 5 is a graph of the adjustment time x (θ, R) with respect to the angle θ. FIG. 6 is a graph of the ratio f (θ, R) with respect to the angle θ.

  As shown in FIG. 5, the graph of x (θ, R) is a straight line passing through the point (M, r) and the point (−M, 2R−r) when θ is in the range of −M to M. Further, as shown in FIG. 6, the graph of f (θ, R) shows that the point (M, r / R) and the point (−M, (2R−r) / R are in the range of θ to −M to M. ).

[Processing when the locus 9 reaches the end of the input surface]
Based on FIG. 7, a process executed by the information processing apparatus 11 when the user operation 3 reaches the end of the input surface will be described. FIG. 7 is a schematic diagram illustrating processing executed when the user operation 3 reaches the end of the input surface and moves along the end from the reached point.

  When the user operation 3 reaches the end of the input surface and moves along the end from the reached point, the locus 9 becomes a broken line illustrated in FIG. An angle 4 with respect to the reference line of the trajectory 9 connecting the position 8a and the reached point is acquired. In addition, the distance acquisition unit 15 acquires the entire length of the trajectory 9 that is a broken line as the distance 10. Subsequent processing is the same as described above.

  That is, the input unit 40 (input surface) detects the position specified by the user operation 3 (user operation) from the input surface provided in the smartphone 100 (electronic device), and the angle acquisition unit 16 (second acquisition unit). ) Is the start position 8a when the locus 9 becomes a broken line because the user operation 3 (user operation) has reached the end of the input surface and moved from the reached end along the end. An angle formed by a part of the locus 9 connecting the (started position) and the reached end portion with respect to a predetermined reference line is acquired.

  Thereby, even if the magnitude | size of the display screen (display part 70) of the smart phone 100 is limited, the information processing apparatus 11 can make a user specify the time to which it advanced the said flexibly.

[Process when locus 9 draws a curve]
Based on FIG. 8, the process which the information processing apparatus 11 performs when the locus | trajectory 9 draws a curve is demonstrated. FIG. 8 is a schematic diagram illustrating processing executed by the information processing apparatus 11 when the locus 9 by the user operation 3 draws a curve as a whole.

  When the information processing apparatus 11 detects that the locus 9 exceeds a predetermined curvature, the position of the user operation 3 at the time of detection is set as the end position 8b, and the position of the slider 7b is transmitted to the output apparatus 12 by the above method. .

  Next, the information processing apparatus 11 resumes the acquisition of the locus 9 with the end position as a new start position 8a. When the information processing apparatus 11 detects again that the trajectory 9 exceeds a predetermined curvature, the information processing apparatus 11 sends the position of the slider 7b to the output device 12 as described above. The information processing apparatus 11 repeats the above processing until the locus 9 cannot be acquired.

  Thereby, the information processing apparatus 11 can make the user draw an arbitrary locus 9.

[Processes executed by the smartphone 100]
Based on FIG. 9, the flow of processing executed by the smartphone 100 will be described. FIG. 9 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 unit 40 acquires a user operation (step 1: abbreviated as S1), the input control unit 50 acquires the locus 9 of the user operation (S2). The operation detection unit 14 determines whether or not the user's long press operation is included in the trajectory (S3, detection step).

  When the long press operation is included (YES in S3), the distance acquisition unit 15 acquires the distance 10 of the locus 9 (S4, first acquisition step). Moreover, the angle acquisition part 16 acquires the angle 4 with respect to the reference line of the locus | trajectory 9 (S5, 2nd acquisition step). The ratio setting unit 17 sets the ratio 5 according to the above method (S6, setting step).

  The position sending unit 18 sends the position of the slider 7b (slider position 1) moved based on the distance 10 and the ratio 5 to the output device 12 (S7, sending step). The display control unit 60 outputs the content 2 from the time when the output of the content specified by the slider position 1 sent from the position sending unit 18 has progressed (S8).

[Effects of the information processing apparatus 11]

Further, the information processing apparatus 11 can increase the number of parameters as compared with the conventional one and allow the user to specify the time for the progress.

  Therefore, the information processing apparatus 11 can solve the first problem and the second problem at the same time, thereby providing an effect that the convenience of the user at the time of outputting the content 2 can be improved.

  Further, for example, a personal computer may be used. In this case, the user performs the user operation 3 using an input device such as a touch pad, and gives the slider position 1 of the slider 7 to the information processing apparatus 11. At this time, the operation detection unit 14 of the information processing apparatus 11 detects that the user operation 3 is started by double-clicking the touch pad, long-pressing the button, or the like.
