Description

  The present invention relates to a portable terminal equipped with operation means such as a touch sensor and a touch keypad, and a processing method and program thereof.

  In order to improve the portability of portable terminals and the like, those having a structure in which a touch sensor, a touch keypad, and the like are mounted as operation means (operation buttons) are widely used. However, touch sensors and touch keypads, unlike physical buttons, produce the same effect as pressing a button when touched. Therefore, the user has no sense of pressing the button and the touch sensor detects that the touch sensor is touch-detected. It is necessary to convey it in an easy-to-understand manner. In addition, when a touch is detected continuously for a long time, it is necessary to determine that it is an erroneous operation and to inform the user of the time until the control for invalidating the touch detection works. Furthermore, since the current mobile terminals such as mobile phones are multifunctional but small, the number of input devices (such as touch key pads) that can be mounted is limited. Therefore, it is necessary to assign a plurality of functions to one input device, but it must be realized that the user can use the input device with a simple operation.

  Therefore, various touch sensors and touch keypads for satisfying these requirements have been developed and distributed on the market. For example, if you press and hold the display unit equipped with a touch sensor, you can zoom in on the display contents displayed on the display unit. There has been reported a technique capable of accurately performing an input operation by determining display information. According to this technology, the display content can be enlarged and displayed depending on the length of time the user touches the touch sensor, and different operations can be performed. Therefore, the operation of the touch sensor can be supported regardless of the downsizing of the device. (For example, refer to Patent Document 1).

  In addition, a technology is disclosed in which a mobile terminal includes a touch keypad having light emitting elements corresponding to a plurality of keys, and when a user selects a key by touching, the light emitting element of the key emits light independently of other light emitting elements. Has been. According to this technology, each touch keypad has an individual backlight, and when a finger touches the desired touch keypad, only the backlight of the touch keypad is brightened. Therefore, the operability of the touch keypad can be improved (see Patent Document 2).

  However, the technology disclosed in Patent Document 1 is operated by causing the mobile terminal to perform different operations depending on the length of time the touch sensor is touched, or by enlarging the display content of the display unit by long-pressing the touch sensor. Although it is possible to provide support, the length of time that the touch sensor is touched is sensual, so it is difficult to grasp the time guideline to reach the desired action, so you can feel sufficient operation support. I can't. Further, the technique disclosed in Patent Document 2 can recognize a key selected by a key whose backlight is lit, but the key whose backlight is lit has a plurality of functions. However, it is not possible to provide support for selecting a desired function from a plurality of functions only by turning on the backlight.

  The present invention has been made in view of such circumstances, and by controlling the illumination state of the backlight used to indicate the mounting position and the functional state of the touch sensor so as to be easily discriminated visually. An object of the present invention is to provide a portable terminal capable of effectively supporting a touch sensor input operation by a user, and a processing method and program thereof.

In order to achieve the above object, the present invention provides a mobile terminal equipped with a touch sensor as an operation means and a touch sensor backlight that illuminates the touch sensor, wherein the touch sensor detects a contact state from the outside. It is determined whether or not it is detected, and control is performed to change the illumination color of the touch sensor backlight while it is determined that the contact state is detected. Control means for activating the function based on information on the function recorded in association with the color information of the illumination color of the touch sensor backlight, and the control means is an illumination color of the touch sensor backlight by changing the, mobile, characterized in that characterized by notifying the time until the detection of the contact state by the touch sensor is determined to be invalid It is a terminal.

Further, the present invention is a processing method in a portable terminal equipped with a touch sensor as an operation means and a touch sensor backlight that illuminates the touch sensor, wherein the touch sensor detects a contact state from the outside. The illumination color of the touch sensor backlight is changed while it is determined that the touch state is detected, and the touch sensor backlight is illuminated when the touch state is not detected. It is determined that the detection of the contact state by the touch sensor is invalid by activating the function based on the function information recorded in association with the color information of the color and changing the illumination color of the touch sensor backlight. This is a processing method characterized by notifying the time until it is done.

According to another aspect of the present invention, there is provided a portable terminal computer equipped with a touch sensor as an operation means and a touch sensor backlight that illuminates the touch sensor, and whether or not the touch sensor detects an external contact state. Control is performed to change the illumination color of the touch sensor backlight while it is determined that the contact state is detected, and the touch sensor backlight is illuminated when the touch state is not detected. It is determined that the detection of the contact state by the touch sensor is invalid by activating the function based on the function information recorded in association with the color information of the color and changing the illumination color of the touch sensor backlight. This is a program that functions as a control means for informing the time until the operation is performed.

  The mobile terminal of the present invention is a mobile terminal equipped with a touch sensor and a touch sensor backlight, and can change the illumination color of the touch sensor backlight while the user's finger is touching the touch sensor. For example, the illumination color of the touch sensor backlight can be changed according to the length of time that the user is touching the touch sensor. Thereby, it becomes possible to support the input operation of the portable terminal in a state in which the user can easily discriminate visually.

It is characterized by visual notification of functional changes. Hereinafter, several embodiments of a mobile terminal equipped with a touch sensor according to the present invention will be described in detail with reference to the drawings.

<< First Embodiment >>
FIG. 1 is a surface view of a portable terminal equipped with a touch sensor according to the present invention. As shown in FIG. 1, the mobile terminal includes an LCD (Liquid Crystal Display) unit 11 serving as a display unit, a touch sensor 12 serving as a user operation unit, and a touch sensor backlight (which illuminates the touch sensor 12). Backlight) 13 is mounted on the surface. The touch sensor 12 is a sensor that can detect that a finger or the like has been touched, and can perform an input operation process equivalent to that when a physical button is pressed by touching the finger or the like.

  RGB_LED is used for the touch sensor backlight 13. That is, in order to control the illumination color (hereinafter referred to as color) of the touch sensor backlight 13, various colors are expressed by setting each luminance of R (red), G (green), and B (blue) of RGB_LED. can do.

  FIG. 2 is a block diagram showing a functional configuration of the portable terminal shown in FIG. As illustrated in FIG. 2, the mobile terminal includes an LCD 11, a touch sensor 12, a touch sensor backlight 13, and a control unit 24. The control unit 24 includes a CPU unit 25 that controls a program for causing the mobile terminal to function, and a memory unit 26 that stores the program. Also, the arrows in FIG. 2 indicate the direction of data exchange. 1 shows the LCD 11, touch sensor 12, and touch sensor backlight 13 as components, and FIG. 2 shows the LCD 11, touch sensor 12, and touch sensor backlight 13 as functional elements. 2 will be described using the same reference numerals.

  Next, the operation of the mobile terminal in the present embodiment will be described. Since the operation of the normal mobile terminal is a well-known technique, the touch sensor backlight 13 changes the color by RGB_LED as a technique according to the present invention. An operation for changing the function of the mobile terminal will be described in detail. Conventionally, there has been a technique for selecting a desired function by turning on the touch sensor backlight 13 while the user touches the touch sensor 12, but the user touches the touch sensor 12 with a finger. Since the technology for selecting a desired function while changing the color of the touch sensor backlight 13 during this time is a feature of this embodiment, the present embodiment is compared with the conventional technology in order to clarify the difference. The operation of the mobile terminal will be described.

  FIG. 3 is a flowchart showing a control flow in which the touch sensor 12 detects the touch and activates the function A in the conventional portable terminal. First, before the touch sensor 12 performs touch detection, the touch sensor backlight 13 is turned on to inform the user that the touch sensor 12 is in a state of performing touch detection. The color to be turned on at this time is white in which the luminance value of each of R (red), G (green), and B (blue) is 100, where the maximum luminance value is 100. Note that the touch sensor backlight 13 is turned off when the touch sensor 12 is not performing touch detection.

  When the touch sensor 1 is in a state of performing touch detection (that is, when the touch sensor backlight 13 is lit), touch detection is performed when the user touches the touch sensor 12 (step S31). In this touch detection, touch detection information indicating that the touch sensor 12 has been touched is notified to the control unit 24. Then, the control part 24 waits for 0.1 second (step S32), and detects a touch state again (step S33). That is, in the processes of steps S32 and S33, the control unit 24 repeatedly detects the touch state every 0.1 second, and continues the touch detection until the touch sensor 12 is no longer touch detected. Note that waiting for 0.1 second is an exemplary expression, and is not limited to that time.

  Here, when the touch sensor 12 is no longer touch-detected (that is, when the touch state is not detected), the function A is activated (step S34), and the touch detection process is terminated (step S35).

  On the other hand, in the portable terminal of the present embodiment, while the touch sensor 12 is detecting a touch with respect to the conventional control flow shown in FIG. 3 (that is, in step S32 and step S33 in FIG. 3), the touch sensor. A process of gradually changing the illumination color (color) of the backlight 13 is added. Moreover, the process which operates a different function with the length of time when the touch sensor 12 is detecting the touch is added. That is, in order to gradually change the color of the touch sensor backlight 13, the luminance value set to R (red), G (green), and B (blue), which are the color components of the touch sensor backlight 13, is stored in the memory unit 26. Keep it.

FIG. 4 is a diagram showing luminance values of R (red), G (green), and B (blue) that change the touch sensor backlight 13 from white to red in the mobile terminal according to the first embodiment of the present invention. . That is, this figure is a table showing the luminance values set for each of R (red), G (green), and B (blue) when the maximum luminance value of the touch sensor backlight 13 is 100. A table of luminance values of R (red), G (green), and B (blue) as shown in FIG.

  That is, as shown in FIG. 4, in the first state of No1, white lights with the luminance values of R (red), G (green), and B (blue) as 100 are lit, and in the state of each subsequent stage, R Only the luminance value of (red) is fixed at 100, the luminance values of G (green) and B (blue) are decreased step by step, and the lighting is gradually made darker in red. In the state of No. 10 at the 10th stage, only the luminance value of R (red) is set to 100, and the luminance values of G (green) and B (blue) are set to 0, respectively, and the darkest red is lit. The luminance value table shown in FIG. 4 is a table in which the luminance values of R (red), G (green), and B (blue) change so that the color gradually changes from white to red.

  FIG. 5 is a flowchart showing a flow of processing for operating different functions depending on the color change control of the touch sensor backlight 13 and the length of the touch detection time in the mobile terminal according to the first embodiment of the present invention. That is, FIG. 5 shows a process of changing the color of the touch sensor backlight 13 while the touch sensor 12 is detecting a touch using the table of luminance values shown in FIG. It is a flowchart which shows the flow of the process which operates a different function according to the length of a certain time.

  As shown in FIG. 5, when touch detection indicating that the touch sensor 12 is touched is performed (step S51), a timer count for measuring the touch detection time is started (step S52). Next, color setting processing of the touch sensor backlight 13 is performed according to the luminance value table shown in FIG. That is, in the first stage, the white backlight color is set with the luminance values of R (red), G (green), and B (blue) of No. 1 in the table of FIG. 4 being 100 (step S53).

  Then, when 0.1 second elapses (step S54), the touch state is detected again (step S55). If the touch state is detected, No2 R (red) = 100, G in the table of FIG. The brightness values of (green) = 90 and B (blue) = 90 are set, and the color of the touch sensor backlight 13 that is slightly reddish in white is set (step S53). In this way, by repeating the processes of steps S53 to S55, the control unit 24 repeatedly performs touch state detection every 0.1 second, and continues touch detection until the touch sensor 12 is no longer touch-detected.

  Further, the control unit 24 repeats the detection of the touch state every 0.1 second in the processing of steps S53 to S55, and R (red) G (green) in each state of No3, No4, ... No10 in the table of FIG. In accordance with the luminance value of B (blue), the color setting process of the touch sensor backlight 13 is performed step by step, and the color of the touch sensor backlight 13 is changed stepwise to a deep red color.

  That is, in the repetition of the touch detection process every 0.1 second in steps S53 to S55, in the color setting process of the touch sensor backlight 13, first, the luminance value of No. 1 in the table of FIG. Set. Then, when detection is determined by touch detection after 0.1 seconds have elapsed and the color setting process of the touch sensor backlight 13 is performed again, the luminance value of No. 2 in the table of FIG. 4 is read and slightly reddish. Set to a bright white. Next, the table of FIG. 4 is read sequentially such that the luminance value No. 3 in FIG. 4 is read, and the color setting process of the touch sensor backlight 13 is repeated.

  In this way, in the processing of steps S53 to S55 in FIG. 5, when processing for 1 second proceeds in 10 repetitions with a period of 0.1 second, in the table of FIG. The state of the luminance value is reached, and the color of the touch sensor backlight 13 is changed stepwise from white to red.

  If the touch state detection continues, the color setting process of the touch sensor backlight 13 is performed according to the brightness value table shown in FIG. FIG. 6 is a diagram showing luminance values of R (red) G (green) B (blue) for changing the touch sensor backlight from red to blue in the mobile terminal according to the first embodiment of the present invention. That is, in the brightness value table shown in FIG. 6, the brightness value of G (green) is always 0, the brightness value of R (red) is decreased in steps from 90 to 0, and the brightness value of B (blue). Gradually increases from 10 to 100.

  In the processing of steps S53 to S55 in FIG. 5, after the touch sensor backlight color is changed from white to red according to the table in FIG. The same control is continued using a table that changes from red to blue in 10 steps in a cycle of 0.1 seconds in accordance with the luminance value table shown in FIG.

  Then, when the touch sensor backlight color has been gradually changed from red to blue, if the touch state detection continues, a table that changes from blue to white as shown in FIG. 7 in 10 steps is used. Continue the same process. That is, FIG. 7 is a diagram showing luminance values of R (red) G (green) B (blue) for changing the touch sensor backlight from blue to white in the mobile terminal according to the first embodiment of the present invention. . In this way, when the color of the touch sensor backlight 13 has been changed in a stepwise manner from blue to white, the control for changing the color of the touch sensor backlight 13 is stopped and the white color is kept on.

  That is, while the user's finger is touching the touch sensor 12 (that is, when the touch state is detected), the control unit 24 performs white → stepwise reddish color in a cycle of 0.1 seconds → The color of the touch sensor backlight 13 is changed so that the color of the touch sensor backlight 13 is changed in the order of red → the color that is bluish in stages → blue → the color that is bluish in steps → white. The white color continues to be lit when the color has changed to white.

  Returning to the flowchart of FIG. 5 again, in the process in which the color of the touch sensor backlight 13 continues to change as described above in the repetitive processing of steps S53 to S55, the user's finger leaves the touch sensor 12 and is in the touch state. If it is determined that no detection has been made, the timer count is stopped while the touch sensor backlight color changed at the time when the touch state is not detected is turned on (step S56). For example, when the finger of the user touches the touch sensor 12 and is released after 1 second, the touch sensor backlight 13 stops the timer count in a state of being lit in red.

  Next, after the timer count is stopped, the control unit 24 performs a touch detection time determination process (step S57), and compares it with a predetermined touch time interval from the count value of the timer. The touch time intervals to be compared at this time are, for example, that interval 1 is 0 to 1 second, interval 2 is 1 to 2 seconds, and interval 3 is 2 seconds or more.

  Here, when the time interval to which the count value of the timer is applied is the section 1 (0 to 1 second), the function A is activated (step S58). If the count value of the timer applies to section 2 (1 to 2 seconds), function B is activated (step S59), and if it falls to section 3 (2 seconds or more), function C is activated (step S60). .

  As described above, according to the mobile terminal of the present embodiment, it is easy for the user to detect that the touch is detected by continuously changing the color of the touch sensor backlight while the touch sensor is detecting the touch. I can tell you. Further, when the user touches the touch sensor and releases the touch sensor in less than 1 second until the color of the touch sensor backlight changes from white to red, the function A can be activated. Similarly, when the function B or the function C is activated, the user can know a change in the function that is operated by a change in the color of the touch sensor backlight, and thus can easily select a desired function from a plurality of functions. Is possible.

<< Second Embodiment >>
Next, a mobile terminal equipped with a touch sensor according to a second embodiment of the present invention will be described. The front view of the portable terminal of the second embodiment is the same as FIG. 1, the configuration diagram is the same as FIG. 2, and the flowchart of the touch sensor backlight control is also the same as FIG. However, the portable terminal in the second embodiment is different from the first embodiment in the usage method of the touch sensor backlight.

  That is, the touch sensor 12 has a characteristic that the user does not intend to operate the touch sensor 12 and may be operated erroneously only by holding the mobile terminal. For this reason, when touch detection is continuously performed for a certain period of time or longer, it is necessary to perform a process of determining touch operation and invalidating touch detection.

  Therefore, for the purpose of notifying the user of the time from when the touch sensor 12 is touched to when the touch sensor 12 is disabled, control for changing the color of the touch sensor backlight 13 is performed until it is determined that the touch is disabled. Do. For example, when touch detection is continuously detected for 30 seconds before the touch sensor 12 determines that the touch is invalid, the color of the touch sensor backlight 13 is gradually changed from white to red in 30 seconds. The user can be notified of the time until touch is disabled.

FIG. 9 is a flowchart showing a process flow of the mobile terminal according to the second embodiment of the present invention.
As shown in this figure, the processing flow of the mobile terminal according to the second embodiment determines whether or not the touch state continues for a predetermined threshold time or more when the touch state is detected in step 55 of FIG. (Step S61). If the touch state has not continued for a predetermined threshold time or longer, the color of the touch sensor backlight 13 is changed (step S62), and the process returns to step S53. If it continues for a predetermined threshold time or longer, it is determined that the touch detection is invalid (step S63).

<< Third Embodiment >>
Next, a mobile terminal equipped with a touch sensor according to a third embodiment of the present invention will be described. The surface view of the mobile terminal of the third embodiment is the same as FIG. 1 and the configuration diagram is the same as FIG. 2, but the control flow of the touch sensor backlight is slightly different from FIG. That is, in the mobile terminal of the third embodiment, while the touch sensor 12 is detecting a touch, the color of the touch sensor backlight 13 and the function to be activated are sequentially changed every second.

  FIG. 8 is a diagram showing the relationship between the color of the touch sensor backlight 13 and the function to be activated in the mobile terminal according to the third embodiment of the present invention. As shown in FIG. 8, as an example of the operation, when the touch sensor 12 detects a touch, the color of the touch sensor backlight 13 is set to No1 white. If the touch sensor 12 determines that the touch has not been detected when the color of the touch sensor backlight 13 is white (that is, if the user removes the finger from the touch sensor 12), the function to be activated is associated with the function A and the function A. To do.

  Next, when the touch sensor 12 performs touch detection for 1 second or more, the color of the touch sensor backlight 13 is changed to red of No. 2 and is activated when it is determined that the touch sensor is not detected within 1 to 2 seconds. The function is changed to function B corresponding to red. In this way, the color of the touch sensor backlight 13 and the function to be activated are changed every second. Thereby, a plurality of functions can be assigned to one operation, and the user can be notified of a change in the function to be activated more easily.

  As mentioned above, although several embodiment was described about the portable terminal of this invention, as a minimum structure of the portable terminal of this invention, the touch sensor 22 used as an operation means, and the touch sensor backlight 23 which illuminates the touch sensor 22 are demonstrated. And a control unit (control means) 24 that changes the illumination color of the touch sensor backlight 23 while the touch sensor 22 detects a contact state from the outside. .

  At this time, the control unit 24 changes the illumination color of the touch sensor backlight 23 according to the length of time that the touch sensor 22 detects the contact state, and the touch sensor 22 detects the contact state. It is configured to activate different functions according to the length of time. Thereby, it becomes possible to support the input operation of the portable terminal in a state in which the user can easily discriminate visually.

  As a preferred embodiment, the control unit 24 associates the change in the illumination color of the touch sensor backlight 23 with the change in the function to be activated. Moreover, the control part 24 is alert | reporting time until it determines with the detection of the contact state by the touch sensor 22 being invalid by changing the illumination color of the touch sensor backlight 23. FIG. Furthermore, the control unit 24 sequentially changes the illumination color of the touch sensor backlight 23 and the function to be activated in correspondence with each other, so that a plurality of operations can be performed for one operation of the touch sensor 22 in a state in which the user can easily visually discriminate. You can also assign these functions.

  According to such a configuration, the touch sensor backlight 23 is used to indicate the mounting position and functional state of the touch sensor 22, and the brightness of the touch sensor backlight 23 is maintained while the touch sensor 22 performs touch detection. The illumination color of the touch sensor backlight 23 is changed with time, not the change of the height. Further, control is performed so as to operate different functions depending on the length of time that the touch sensor 22 detects touch. At this time, since each illumination color is associated with each function, the function corresponding to the illumination color of the touch sensor backlight 23 can be visually notified to the user. Furthermore, by changing the illumination color of the touch sensor backlight 23 at the boundary of the touch detection time for operating different functions, the user can be notified of the timing at which the function mode changes. As a result, the user can select a desired function mode from a plurality of function modes only by touching the touch sensor 22 once.

  More specifically, the control unit 24 changes the color of the touch sensor backlight 23 in the order of red → blue → green → white and the like while the user's finger is touching the touch sensor 22. Correspondingly, different functions are activated. Accordingly, it is possible to visually inform the user of the type of function that operates when the user lifts his / her finger from the touch sensor 22. Thereby, the user can easily select and start a desired function from a plurality of functions assigned to the touch sensor 22. Further, by changing the color of the touch sensor backlight 23 stepwise (for example, red → blue is changed in ten steps), the user can know the length of time that the touch sensor 22 is touched. For example, the user can know the remaining time until it is determined that the detection of the contact state by the touch sensor 22 is invalid.

  Further, according to the portable terminal having such a configuration, the illumination color of the touch sensor backlight 23 can be changed according to the length of time that the user's finger is touching the touch sensor 22, so that the user can visually It becomes possible to support the input operation of the portable terminal in a state where discrimination is easy. Accordingly, it is possible to convey the same feeling as a physical button press to the user, and a desired function can be visually selected by changing the illumination color of the touch sensor backlight. It can be further improved. In addition, when the touch sensor is unconsciously pressed for a long time, the pressing can be invalidated, so that the usability of the mobile terminal can be further improved. Furthermore, the operability when many functions are assigned with a small number of input devices is not impaired.

  In other words, if the user checks the color of the touch sensor backlight 13 from when the finger touches the touch sensor 12 and releases the finger from the touch sensor 12 at the stage of the reddish color, the user can operate the mobile terminal. A can be activated. Similarly, if the finger is released from the touch sensor 12 at the stage of the bluish color, the function B can be activated for the portable terminal, and from the touch sensor 12 when the color is close to white or white. If the finger is released, the function C can be activated for the portable terminal. In this way, the user can activate a desired function by selecting a function corresponding to the color of the touch sensor backlight 13.

  In each of the above embodiments, the case where there is one kind of change in color and time has been described. However, the present invention is not limited to this, and other color combinations or different time intervals may be used. The interval may be changed.

  Note that the portable terminal described above has a computer system inside. Each process described above is stored in a computer-readable recording medium in the form of a program, and the above process is performed by the computer reading and executing the program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.
