Device with touch sensor

Technical field

[0001] The present invention relates to an apparatus including a touch sensor as an operation means, and in particular, switches a control method depending on how the touch sensor is operated.

Background art

[0002] Conventionally, touch sensors of various shapes such as a linear shape, a rectangular shape, and a circular shape have been known. In addition, a capacitance method for detecting a capacitance that changes with the touch, a touch type, Various systems have been developed, such as a resistance system that detects resistance that changes with the hose, or an ultrasonic system that detects changes in the propagation of ultrasonic waves that accompany the touch. From the detection information of these touch sensors, the touch position can be detected if there is a touch, and the movement distance when the finger is moved on the touch sensor and the movement distance that changes over time are differentiated by time. Thus, the moving speed and acceleration can be detected. A touch sensor capable of inputting such information is widely used as an operation unit for selecting a position, a direction, and the like on a display screen in many display devices.

[0003] Patent Document 1 below describes a display device in which a scroll switch is configured with a touch sensor integrated with a screen, and scrolling of a road map is selected with the scroll switch.

[0004] FIG. 8 (a) shows scroll switches 21 to 26 displayed on the screen of this apparatus. In this device, for example, when the scroll switch 21 is touched, the display area 30a displayed on the screen moves upward in the road map data 40 stored in the memory as shown in FIG. 8 (b). To do. Then, when the position of the display area 3 Ob is reached when the operation of the scroll switch 21 is completed, even after the operation is completed, scrolling is continued for a predetermined distance based on the scroll speed at the end of the operation. Scrolling stops at the position.

[0005] As described above, the scrolling display as if the moment of inertia is applied to the applied force can evoke a sense of realism to the user.

Patent Document 1: JP 2004-117830 A Disclosure of the invention

Problems to be solved by the invention

However, the conventional display device has a large amount of data to be scrolled. In some cases, it is necessary to keep touching the touch sensor for a long time or repeatedly touch the touch sensor, and the operation is troublesome. Also, scrolling cannot be controlled at the intended moving speed.

[0007] The present invention has been made in view of such circumstances, and an object thereof is to provide a device that can be controlled as intended by a simple operation of the touch sensor. Means for solving the problem

[0008] In the present invention, in an apparatus having a touch sensor as an operation means, a control unit that controls the operation of the apparatus according to the operation of the touch sensor is provided, and the control unit terminates the operation of tracing the touch sensor. Depending on the situation, the control method of the operation is changed.

[0009] For this reason, the device operates differently just by changing the "how to finish tracing" when tracing the touch sensor with a finger or the like.

[0010] Further, in the apparatus of the present invention, when the control unit performs the first operation to stop the movement while touching the touch sensor at the position where the touch sensor is finished, the control unit finishes tracing the touch sensor. The control method is changed when the second operation is performed to release the touch sensor force while continuing to move at the specified location.

[0011] For this reason, the device performs different operations for the first operation for stopping the finger after tracing the touch sensor and for the second operation for stopping the finger after tracing the touch sensor.

[0012] In the apparatus of the present invention, when the second operation is performed, the control unit further changes the control method according to the moving speed immediately before being released from the touch sensor.

[0013] Therefore, the operation of the device can be changed by paying the finger from the touch sensor early or late.

[0014] The apparatus of the present invention further includes a display unit, and the control unit controls the display operation of the display unit in accordance with the operation of the touch sensor.

[0015] Therefore, the display operation can be changed by changing the "how to finish tracing" when tracing the touch sensor with a finger or the like. [0016] In addition, in the apparatus of the present invention, when the control unit performs the first operation, the display unit continues to update the display unit until the touch sensor is traced and the touch sensor is traced. When the second operation is performed, the update of the display target is continued until the touch sensor is traced, and the update is performed when the touch sensor is traced. Is controlled to continue automatically.

[0017] Therefore, when the finger is removed after tracing the touch sensor, the display object is automatically updated so that the inertia acts on the force as well.

[0018] In addition, in the apparatus of the present invention, when the control unit finishes tracing the touch sensor when the second operation is performed, the control unit has a speed corresponding to the moving speed immediately before that time, and Control is performed so that the updating is automatically continued for a period corresponding to the moving speed.

[0019] Therefore, if the finger is paid hard, the update is continued at a high speed for a long time, and if the finger is softly paid, the update is delayed and the update is continued at a speed for a short time.

[0020] Further, in the apparatus of the present invention, the control unit performs control so as to stop the update if there is a contact with the touch sensor while the update is automatically continued.

[0021] Therefore, the display during the automatic update can be stopped by touching the touch sensor with a finger.

Furthermore, the apparatus of the present invention includes an audio output unit, and the control unit controls the output sound from the audio output unit in accordance with the operation of the touch sensor.

[0023] Therefore, the voice operation can be changed by changing the "how to finish tracing" when tracing the touch sensor with a finger or the like. Further, with such a configuration, even when the device is operated with a remote controller that does not have a display unit, it is possible to notify the user that the scroll is being performed by sound.

[0024] In addition, in the apparatus of the present invention, when the first operation is performed, the control unit continues the voice output from the voice output unit until the touch sensor is traced, and when the touch sensor is traced. When the second operation is performed, the audio output of the audio output unit is continued until the touch sensor is traced, and when the touch sensor is traced, Control is performed so that the audio output is continued (while the operation of the device corresponding to the second operation continues).

[0025] Therefore, after tracing the touch sensor, if you remove your finger, the inertia will act on the force. As you can see, the audio update continues automatically.

The invention's effect

[0026] The device of the present invention can be controlled as intended simply by changing the “how to finish tracing” of the touch sensor, and the functionality of the touch sensor as an operating means can be enhanced.

[0029] As an embodiment of the present invention, a scroll display device used for a portable terminal will be described. Fig. 1 is a schematic diagram showing the appearance of this scroll display device, Fig. 2 is a block diagram of this device, Fig. 3 is a diagram for explaining the operation of a finger on the touch sensor, and Fig. 4 is a display section of this device. FIG. 5 is a diagram illustrating the relationship between finger operation and scrolling, FIG. 6 is a diagram illustrating the scrolling speed during automatic scrolling, and FIG. 7 is a diagram illustrating this device. It is a flowchart which shows this operation | movement.

[0030] As shown in Figs. 1 and 2, the scroll display device displays a sensor unit 51 having a circular touch sensor, an input unit 52 having a key, and a display unit 53 for displaying information. A memory unit 54 for storing information, an audio output unit 56 composed of a speaker for outputting audio, and the display on the display unit 53 and the audio output unit 56 based on input information from the sensor unit 51 and the input unit 52 And a processing unit (control unit) 55 for controlling the output sound from the.

[0031] The memory unit 54 stores, for example, a telephone directory list including a large number of names. When the user selects one of the input units 52 from the input unit 52, the processing unit 55 reads data from the memory unit 54. As shown in FIG. 4 (a), the number of personal names that can be displayed on the display unit 53 is displayed with the selected personal names at the top. When transmission to the selected personal name is also instructed by the input unit 52, the transmission to the other party is executed using the communication function (not shown) of this apparatus. Such operations are well known in the art and will not be described in detail here. Note that the memory unit 54 is not particularly necessary when the information displayed on the display unit 53 is also acquired by an external force through communication means or the like.

In this scroll display device, when the user traces the touch sensor of the sensor unit 51 with his / her finger, the processing unit 55 scrolls the name of the person displayed on the display unit 53 by a display method according to the “how to trace”. To do.

[0033] As shown in FIG. 3, the finger 60 (FIG. 3 (a)) touching the touch sensor 511 of the sensor unit 51 moves on the touch sensor 511 as shown in FIG. There are two cases: when stopping at the position after movement (Fig. 3 (b)) and when touching the touch sensor 511 with the finger 60 while maintaining the moving speed without stopping at the position after movement (Fig. 3 (c)). Yes, in this description, the former “how to trace” “Stop”, the latter “how to trace” will be called “payment”.

[0034] When the user moves the finger 60 on the touch sensor 511, the processing unit 55 acquires detection information of the touch sensor 511 at a predetermined sampling period, and detects the moving direction and moving distance of the finger during that period. Then, the scroll direction is determined from the moving direction, the number of persons (number of items) to be updated by scrolling is determined from the moving distance, information to be displayed is read from the memory unit 54, and the display unit 53 Update the scroll display.

[0035] FIGS. 4B to 4E show examples of scroll display. When the finger is moved in the direction of the arrow on the touch sensor 511, the names appear on the upper part of the display unit 53, the names of the names disappear one after another, and the same number of new names appear on the screen.

In this apparatus, a semicircular indicator 531 is displayed on the screen of the display unit 53 instead of the scroll bar. This indicator 531 moves up and down to indicate the relative position of the displayed data in all data. In addition, a white point 532 is displayed on the indicator 531, and the white point 532 rotates on the indicator 531 in accordance with scrolling (when the white point 532 is rotated to a position where the white point 532 is hidden, the indicator 531 A new white spot appears at the nominal position). Therefore, even when the vertical movement of the indicator 531 is slow because the total amount of data is large, the user can check the direction of the scroll by looking at the movement of the white point 532.

[0037] Regardless of whether the user ends by "stop" or "payment", the scroll to the end point is the same, and the item moves on the screen according to the movement distance of the finger.

When the movement of the finger 60 on the touch sensor 511 is terminated by “stop”, the processing unit 55 stops updating the display unit 53 and maintains the previous display.

[0039] On the other hand, when the movement of the finger 60 on the touch sensor 511 is terminated by "pay", the processing unit 55 determines the initial scroll speed from the speed of the finger at the end, and continues scrolling at that speed. To do. Therefore, even if the finger 60 is separated from the touch sensor 511, the personal name is updated until the stop time described later comes, and accordingly, the indicator 531 moves in the vertical direction, and the white point 532 of the indicator 531 continues to rotate.

FIG. 5 illustrates the relationship between the amount of movement of the finger (solid line) for “payment” and “stop” and the amount of movement of the item in the scroll display (dotted line). [0041] FIG. 5 (a) shows the case of "payment". While the touch sensor is being traced with a finger, the processing unit 55 determines the amount of movement of the item according to the movement distance of the finger. The amount of movement of items in scroll display increases in proportion to the distance of finger movement. When the finger is released from the touch sensor by “payment”, the processing unit 55 identifies the end by “payment” because the final movement amount within the specified time immediately before the finger is released exceeds the specified movement amount. . Then, the scroll speed (initial speed) when the finger is released is calculated, and the subsequent scroll display is controlled according to the initial speed.

FIG. 5B shows the case of “stop”. While the touch sensor is traced with a finger, the processing unit 55 determines the amount of movement of the item according to the movement distance of the finger. Therefore, the amount of movement of the item in the scroll display increases in proportion to the distance of finger movement. When the finger is released from the touch sensor by “stop”, the processing unit 55 identifies that the operation has been ended by “stop” because the final movement amount within the specified time immediately before the finger is released is equal to or less than the specified movement amount. Then, the display at the time when the finger is released is maintained.

[0043] FIG. 6 shows the scrolling speed after the finger movement on the touch sensor is finished with "payment". The horizontal axis shows the time in units of 200ms, and the vertical axis shows the amount of scroll movement within the unit time. Time 0 indicates the time when the finger is released from the touch sensor force due to “payment”. The processing unit 55 calculates the scroll speed at the time when the finger is released as the initial speed, and when the initial speed (SO) is high (that is, Sl, S2 (where S2> S1) as threshold values, S0> S2 In the case of S1), and in the case of medium speed (ie, S2≥S0≥S1), in the case of low speed (ie, S1> S0). ) Controls the scroll display speed of the display unit 53 using the speed transition pattern (3).

Therefore, depending on the speed at which the finger is applied, the time to stop the scrolling is different, and the number of items to be updated is different.

[0045] In addition, in each speed transition pattern, deceleration from the initial speed is set in multiple stages, and in the latter half of the convergence process, it is specified that the scroll speed decreases as the stop time approaches, so the applied force is also The physical strength of the displayed item can be given to the user as if it is rotating with its own inertia after receiving the “pay” operation of the finger. [0046] Note that even if the user is scrolling according to each speed transition pattern, if the user touches the touch sensor, the scrolling stops at that point.

Next, based on FIG. 7, the processing procedure of the processing unit 55 of this scroll display device will be described. FIG. 7 (a) shows the processing procedure of the processing unit 55 when the finger is touching the touch sensor. In this case, the processing unit 55 receives the finger position information from the touch sensor at a predetermined sampling period, and executes processing based on the position information (receives and processes sensor force information).

The processing unit 55 determines from the finger position information acquired from the touch sensor whether or not the finger contact with the touch sensor is newly performed (step 1). If yes, identify whether scrolling is ongoing (ie, item moving speed is greater than 0) (step 2), and if scrolling is ongoing, stop scrolling (step 3). ).

[0049] If the answer is No (contact of the finger to the touch sensor is ongoing) in step 1, it is determined whether or not the touch sensor force is released (step 4). When the finger is released (Yes in Step 4), it is identified whether or not the final change in finger position information that has changed within the previous specified time is greater than a predetermined specified value (Step 5). If the amount of change is greater than the specified value (ie, “pay”), calculate the initial speed of the scroll display from the final amount of change (step 6) and set the scroll speed to the initial speed (step 7).

[0050] In step 5, if the final change amount is not more than the specified value (ie, "stop"), the scroll speed is set to 0 (step 9).

[0051] If it is No in step 4 (a finger is in contact with the touch sensor), the item displayed on the screen is moved according to the amount of change in the position information of the finger (step 8).

[0052] FIG. 7 (b) shows a processing procedure of the processing unit 55 when the finger is not touching the touch sensor. In this case, the processing unit 55 performs the following processing every time the specified time elapses. Execute (process at regular intervals regardless of the sensor).

[0053] Identifies whether or not the scrolling is continuing (the item moving speed is greater than 0) (step 1 0). If Yes, whether or not the item moving speed is greater than the minimum moving speed Is identified (step 11). If yes, the item is moved according to the moving speed (step 12) and the moving speed is reduced (step 13). [0054] If the answer is No (the moving speed of the item is equal to or lower than the minimum moving speed) in step 11, scrolling is stopped (moving speed is set to 0) (step 14).

[0055] If it is No (scroll stop state) in step 10, that state is maintained.

[0056] As described above, in this scroll display device, the scrolling operation changes depending on how to end the touch sensor with a finger or the like, and when it is terminated by "stop", the scrolling is stopped and terminated by "payment". In this case, scrolling continues and the duration is determined by the “pay” speed.

[0057] Therefore, it is possible to increase the "payment" speed and move a large number of display items in a short time, or reduce the "payment" speed and move the display items a little. , You can efficiently achieve the scroll you want without touching the touch sensor for a long time or repeatedly touching it.

[0058] In addition, the automatically continuing scrolling stops when a finger touches the touch sensor. Therefore, scrolling can be stopped at a desired position.

Here, the shape of the force touch sensor described for the circular touch sensor can be set as appropriate, and various shapes such as a linear shape and a rectangular shape can be adopted.

[0060] In addition, here, two examples of "stop" and "pay" are described as the end method when tracing the touch sensor, but the other end methods are associated with the control method at that time. In this way, the functionality of the touch sensor operation unit can be improved by switching the display control depending on the end of the touch sensor.

[0061] Further, here, the power described in the example of controlling the scroll of the phone book list according to the end when the touch sensor is traced. In the case of controlling the display in this way, the scroll of the music list or the road map is performed. In addition, various display switching such as image data and page turning of electronic books can be controlled, and the present invention is widely used when the display target to be focused is switched by the operation of the touch sensor. It is possible to apply.

[0062] The present invention can also be applied to other than display control. For example, it is possible to perform control such as changing the playback sound depending on how to end the touch sensor. sand That is, the processing unit 55 controls the output sound from the audio output unit 56 in accordance with the operation of the touch sensor. In this case, the same processing as in the case of the display unit control described above can be performed. That is, in the case of the “stop” operation, the processing unit 55 continues to output the sound from the sound output unit 56 until the touch sensor is finished tracing, and outputs the sound when the touch sensor is finished (stopped). The audio output unit 56 is controlled to stop. On the other hand, in the case of the “payment” operation, the processing unit 55 continues the audio output of the audio output unit 56 until the touch sensor is traced, and at the time when the touch sensor is traced (payment), The audio output unit 56 is controlled so that the audio output is continued while the operation is continued.

With such a configuration, the sound can be changed by changing the “how to finish tracing” when tracing the touch sensor with a finger or the like. In addition, even when the device is operated with a remote controller that does not have a display unit, it is possible to notify the user that the scroll is being performed by sound. If you touch the finger after tracing the touch sensor, the voice update will continue automatically as if the inertia is acting on the force.

[0064] While various embodiments of the present invention have been described above, the present invention is not limited to the matters shown in the above-described embodiments, and those skilled in the art can make changes based on the description and well-known techniques. · Application is also the scope of the present invention, and is included in the scope of protection.
