Description

  The present invention relates to a touch panel protection device, a touch panel protection method, and a touch panel protection program suitable for protecting a touch panel or a device body with an information processing device such as a mobile phone having a touch panel disposed on the front surface of the display device.

  An information processing apparatus in which a touch panel is attached to a display device can perform an intuitive input operation on displayed content. For this reason, not only PDA (Personal Digital Assistants) and small computers but also mobile phones and PHS (Personal Handyphone System) have been adopted.

  However, information processing apparatuses equipped with touch panels have become widespread, and their uses have expanded, and user handling has become diversified. For this reason, the danger that an unexpected press will be applied to a touch panel will generate | occur | produce and the danger that the internal circuit of a display apparatus or an information processing apparatus will be damaged has increased. For example, if a cellular phone equipped with a touch panel is placed in a pants pocket with the panel surface facing out, the display device may be damaged.

Therefore, as a first related technique of the present invention, when an obstacle is present in the light receiving allowable range by making light incident on the front surface of the coordinate input device and detecting the reflected light, this is detected by light shielding. It has been proposed (see, for example, Patent Document 1). Further, it is possible to arrange one pressure detector at each of the four corners of the bottom of the display keyboard for display, and to issue an alarm when any of these pressure detectors detects an abnormal pressure. Has been proposed as a second related technique (see, for example, Patent Document 2).

For this reason, the information processing apparatus provided with the coordinate input device is not only increased in size, but also has a problem that power consumption of the information processing apparatus increases because it is necessary to always project light.

  In the case of the second related technology, since the pressure detectors are arranged one by one at the four corners of the bottom of the display keyboard for display, the information processing device becomes thicker by the thickness of the pressure detector. There is. In addition, if the display keyboard is not facing up, such as when the user is lying down and operating the information processing device, the pressure applied to the pressure detector may be reduced or negative pressure may be applied. There was also a risk of occurrence.

  <First Embodiment of the Invention>

  Next, a first embodiment of the present invention will be described.

  FIG. 10 shows a circuit configuration of a mobile phone using the touch panel protection device according to the embodiment of the present invention. The cellular phone 100 includes a CPU (Central Processing Unit) 101 and a main control unit 103 including a memory 102 such as a ROM (Read Only Memory) in which a control program executed by the CPU 101 is stored. Yes. The main control unit 103 controls the following units.

  The display unit 104 includes a liquid crystal display (not shown) or an organic EL (Organic Electro-Luminescence) display and its drive control circuit, and displays various types of visual information. The touch panel 105 is disposed so as to cover the entire display of the display unit 104. The pressed position detection unit 106 detects which position on the touch panel 105 is pressed based on information obtained from the touch panel 105. The pressed area calculation unit 107 calculates the area that is simultaneously pressed on the touch panel 105 including one initial pressing point. Since one initial pressing point is included, the total of the areas when a plurality of pressing points are simultaneously present on the touch panel 105 is not calculated. The area increase rate calculation unit 108 calculates the increase rate when the area calculated by the pressed area calculation unit 107 increases with time. The threshold storage unit 109 stores several thresholds when an alarm is output to protect the touch panel 105. The stop time measuring unit 110 measures whether the pressing position of the touch panel 105 detected by the pressing position detecting unit 106 is stopped and the duration of the stop when the pressing position is stopped.

  The operation input unit 111 includes switches such as a key switch and a slide switch (not shown), and constitutes an input unit other than the touch panel 105. The alarm output unit 112 outputs an alarm by sound, light, or vibration using a speaker, a light emitting diode, or a vibrator (not shown). It is also possible to send an alarm display signal to the display unit 104 and output an alarm from the display unit 104. The application software storage unit 113 stores various application software used in the mobile phone 100. The mobile phone basic function unit 114 is an assembly of circuit devices that should be provided as the mobile phone 100 other than the devices described above. In addition to a communication control unit (not shown), circuit devices such as a digital camera, a television tuner, and a GPS (Global Positioning System) device are usually included.

  Note that at least a part of various devices such as the pressed position detection unit 106 other than the main control unit 103 constituting the mobile phone 100 may be configured as hardware, or a control program stored in the memory 102 by the CPU 101. By executing the above, it can be realized as software.

  FIG. 11 shows the position detection principle of the pressed position detection unit. This will be described with reference to FIG.

  The touch panel 105 has electrodes 121 arranged in a matrix on the entire surface thereof. The touch panel 105 has a capacitance detection electrode pattern (not shown) formed on, for example, glass or PET (polyethylene terephthalate) film, and on the outer side thereof is acrylic such as glass or polymethyl methacrylate resin (Polymethyl methacrylate). It is equipped with a resin screen. Between the electrodes 121, 121,... Constituting the electrode pattern and the surface of the touch panel 105, electrostatic capacitances 122, 122,. When the user of the mobile phone 100 touches the surface of the touch panel 105 with the finger 123, the charge at the contact position 124 with the touch panel 105 is discharged most.

  In FIG. 11, the touch panel 105 is represented as a cross section cut perpendicularly to the panel surface, but the discharge characteristics can be represented as a curve 125 depending on the relationship between the discharge capacity and the position. The position of the peak of the curve 125 coincides with the contact position 124. In some cases, the contact position 124 does not accurately correspond to any of the electrodes 121, 121,..., But even in this case, the discharge amount of these electrodes 121, 121,. By complementing, the contact position 124 can be obtained as the “center of gravity position”.

FIG. 12 shows the calculation principle of the pressing area by the pressing area calculation unit. This will be described with reference to FIG. A curve 125 indicated by a solid line indicating the discharge characteristics shown in FIG. 11 is a relatively early stage in which the finger 123 is pressed against the above-described screen (hereinafter simply referred to as the touch panel 105) arranged on the surface of the touch panel 105. Is shown. By comparing this with the first threshold value TH ₁ stored in the threshold value storage unit 109, the pressed area calculation unit 107 can determine the contact distance D of the touch panel 105 at a relatively early stage when the finger 123 contacts the touch panel 105. ₁ can be sought. Since the finger 123 touches the touch panel 105 two-dimensionally, the pressing area as the contact area can be obtained by two-dimensional calculation.

A curve 131 shown by a one-dot chain line in FIG. 12 shows an example when the finger 123 shown in FIG. 11 presses the touch panel 105 more strongly as time passes. By area the finger 123 is in contact with the touch panel 105 is increased, the electrodes 121 and 121 shown in FIG. 11, the discharge region is spread in ......, contact distance D ₂ of the first touch panel 105 exceeds the threshold value TH ₁ contact It is longer than the distance D _1. Thereby, the calculated contact area (pressing area) also increases.

By the way, the pressing area calculated by the pressing area calculation unit 107 is compared with the second threshold TH ₂ stored in the threshold storage unit 109. Here, the second threshold value TH ₂ indicates that the pressing area is more than half of the surface of the touch panel 105, for example, when the user presses the touch panel 105 into the pocket of the pants with the surface of the mobile phone 100 exposed. A value corresponding to such an area is set. Accordingly, the pressing area to calculate the pressing area calculation unit 107 is checked whether it is regular second threshold TH ₂ or more, the pressing area exceeds a second threshold value TH ₂ is alarm output unit 112 outputs an alarm It is like that.

  On the other hand, the area increase rate calculation unit 108 shown in FIG. 10 checks the increase in the contact area based on the position where the finger 123 is in contact with the touch panel 105 every time unit time passes. The rate of increase of the pressing area of the touch panel including one pressing point can be calculated as the area increase rate. The reason for calculating the pressing area “including one initial pressing point” is to add the areas of all the detection points when the mobile phone 100 is a device that performs multi-point position detection. This is because it is not suitable for the analysis of the area increase rate starting from one contact point, and this is excluded.

The area increase rate calculated by the area increase rate calculation unit 108 is compared with the third threshold TH ₃ stored in the threshold storage unit 109. The third threshold value TH ₃ is set to a value corresponding to a case where the speed at which the user presses the finger 123 (FIG. 11) is abnormally high. Therefore, when the area increase rate per unit time exceeds the third threshold TH ₃ , there is a possibility that a user unfamiliar with the operation touches the touch panel 105 so as to strike the finger 123. If this continues, the touch panel 105 may be damaged. Therefore, when the area increase rate exceeds the third threshold TH ₃ , the alarm output unit 112 outputs an alarm.

On the other hand, the stop time measuring unit 110 shown in FIG. 10 checks whether or not the center position of the pressing position detected by the pressing position detecting unit 106 has changed, and the time when the pressing continues and the pressing position is held. Is measured as the stop time. If the measured time is unusually long, such as 1 minute or more, except for special cases such as when a special operation is requested by the game software, other than the user's operation It is conceivable that the pressing force is continuously acting on the touch panel 105 due to the above. For example, when the mobile phone 100 is left on a desk, an example is a case where the end of a thick book is placed in contact with the surface from which the touch panel 105 is exposed. Even in this case, the touch panel 105 may be damaged or the quality thereof may be deteriorated. Therefore, when the pressing time on the touch panel 105 exceeds the fourth threshold TH ₄ that is longer than the time assumed by the currently operating application software, the alarm output unit 112 outputs an alarm.

The threshold value storage unit 109, first to fourth threshold TH ₁ to TH ₄ are stored as described above. Here, a plurality of threshold values may be stored for the fourth threshold value TH ₄ , and the user can select from among them as necessary, or the application software (game) in which the main control unit 103 is currently operating. (Including software of the above) may be selected.

  FIG. 13 shows an example of the touch panel alarm setting screen. The user can display the touch panel alarm setting screen 141 on the display unit 104 shown in FIG. 10 to set an alarm mode. This will be described with reference to FIG.

On the touch panel alarm setting screen 141, three types of alarms can be selected and output. By default, both are output as alarms, but can be canceled by removing the check symbol. Among them, the “acceleration (impact) alarm” is an alarm when the area increase rate as the calculation result of the area increase rate calculation unit 108 exceeds the _third threshold TH ₃ . The “alarm for pressing of a large area” is an alarm when the pressing area calculated by the pressing area calculation unit 107 exceeds the _second threshold TH2. The “alarm for exceeding the one-point stationary time” is an alarm when a time exceeding the fourth threshold value TH ₄ is measured by the stop time measuring unit 110.

The fourth threshold TH ₄ for the last “alarm for exceeding the one-point stationary time” is set to 2 minutes as a default value, but the user can change it to an arbitrary time. Further, the user can also select an alarm output form by the alarm output unit 112. Among these, “vibration” is effective when the mobile phone 100 is put in a pocket with the touch panel 105 exposed, but it may not be desirable to apply vibration in a “one-point stationary” state. Therefore, in the case of “one point stationary”, it is excluded to perform an alarm by “vibration”.

  FIG. 14 shows an alarm output process related to the touch panel according to the present embodiment. This will be described with reference to FIGS. 10 and 13.

When receiving a report that the third threshold value TH ₃ has been exceeded (step S201: Y), the main control unit 103 outputs an “acceleration (impact) alarm” from the setting content displayed on the touch panel alarm setting screen 141. A check is made to see if this is the case (step S202). When “acceleration (impact) alarm” is output (Y), an alarm is output according to the “alarm output method” in the setting contents displayed on the alarm setting screen 141 (step S203). Thereafter, the processing is returned to the first control (return). For example, a message such as “Let's touch more gently on the touch panel” is output by voice.

  If it is set not to output an “acceleration (impact) alarm” (step S202: N), the process returns to the first control without outputting an alarm (return). Similarly, no alarm is output when all outputs in the “alarm output method” are not set.

When receiving a report that the second threshold value TH ₂ has been exceeded (Step S201: N, Step S204: Y), the main control unit 103 from the setting contents displayed on the touch panel alarm setting screen 141 at the initial control stage. It is checked whether an “alarm for pressing of a large area” is output (step S205). When the “alarm for pressing of large area” is output (Y), an alarm is output according to the “alarm output method” in the setting contents displayed on the alarm setting screen 141 (step S206). Thereafter, the processing is returned to the first control (return). For example, a message such as “The touch panel is hard” is output by voice.

  If it is set not to output the “warning against pressing of a large area” (step S205: N), the processing is returned to the first control without outputting the warning (return). Similarly, no alarm is output when all outputs in the “alarm output method” are not set.

On the other hand, when the main control unit 103 receives a report that the fourth threshold value TH ₄ has been exceeded in the initial control stage (step S201: N, step S204: N, step S207: Y), a touch panel alarm setting screen is displayed. It is checked from the setting contents displayed in 141 whether an “alarm for an excess of one point stationary time” is output (step S208). When “Alarm for exceeding one point rest time” is output (Y), an alarm is output according to “Alarm output method” in the setting contents displayed on the alarm setting screen 141 (step S209). ), And then return the process to the first control (return). For example, a message such as “Something hits the touch panel” is output by voice.

  If it is set not to output the “warning for exceeding the one-point stationary time” (step S208: N), the processing is returned to the first control without outputting the warning (return). Similarly, no alarm is output when all outputs in the “alarm output method” are not set.

  As described above, according to the present embodiment, not only can the touch panel 105 itself be prevented from being damaged, but the touch panel 105 can be used as a sensor for protecting the mobile phone 100, thereby Circuit protection can also be achieved. Further, by using the pressed area calculation unit 107 and the area increase rate calculation unit 108 used in the present embodiment, for example, application software for displaying and playing a piano keyboard on the display unit 104 is used for the information processing apparatus. In this case, it is possible to freely control the sound output according to the keystroke of the keyboard.

  In the present embodiment, the present invention has been described by taking the cellular phone 100 as an example. However, the present invention can be applied to any information processing apparatus having a touch panel such as a PDA, PHS, and portable computer. Of course.

  Note that there is a slight difference in the softness of the skin depending on the user's age, gender, occupation type, or individual difference, and there is a possibility that a slight error may occur in the calculation of the area increase rate calculation unit 108. In order to correct such an error, the degree of softness of the skin may be measured by a method such as causing the user to lightly press the surface of the touch panel 105.
