Running in the connection, the system is in the middle of the keyboard, and the key of the keyboard and the sensor are calculated. The mode is used to calculate the induction when the sensor receives at least one of the sensed static pressure signals. Sensing each press to dry =: and confirming that the key different module corresponding to the maximum sensing intensity is used to start 6 201012179 when the sensor receives the pressing signal to obtain the pressing time of the user pressing the confirmation button; and display The module is configured to zoom in and display the current character according to the user pressing time and the character display order corresponding to the confirmed button '. * A method for inputting characters by using a button sensing function, which is applied to a mobile device with a keyboard and a sensor, the keys of the keyboard being connected to the sensor, the method comprising: when the sensor receives the pressing transmitted by the at least one button When the signal is received, the sensing sensor senses the sensing intensity of each pressing signal, and starts the counting time at the same time to obtain the pressing time of the user; compares the sensing intensity of each pressing signal to obtain the maximum sensing intensity, and confirms that the maximum sensing intensity corresponds to And pressing and displaying the current character according to the user pressing time and the character display order corresponding to the confirmed button. Compared with the prior art, the system and method for prompting input of characters by using a button can perform an enlarged display or a voice prompt for the current character. Therefore, it is possible to reduce the misoperation of the elderly or the amblyopic group. ® [Embodiment] As shown in Fig. 1, a functional module diagram of a system for prompting input of characters by means of a key touch is provided. The system 10 (hereinafter referred to as "key sensing system 10") for prompting input of characters by means of a key sensor operates in the mobile device 1 with the keyboard 12. The mobile device may be an electronic product with a keyboard such as a mobile phone, a PDA, a palmtop computer, a palmtop translator, a handheld game console, a digital camera, a digital camera, an MP3 Player or an MP4 Player. A sensor is mounted under each of the keys of the keyboard 12, and the sensor is, but is not limited to, a 'thermal sensor, a pressure sensitive device, and the like. The mobile device 1 also includes a memory 14. The memory 14 stores various types of data, including an operating system, various applications, and data set and generated during the process of using the button 10 to prompt for character input. The memory 14 can be the memory of the mobile device 1, and is also an external memory card, such as a SIM card (Smart Media Card), an SD card (Secure Digital Card), and a CF card. Card (Compact ❹ Flash Card, Standard Flash Memory Card), MMC Card (Multi Media Card), MS Card (Memory Stick), XD Card (Extreme Digital Card), TF Card (Trans Flash Card) and so on. The button sensing system 10 is a program running on the action skirt 1. By executing the program segment, each finger under the touch of the finger can be calculated when the user touches the mobile device keyboard 12 The sense of the device should be 'intensity' and the button with the highest inductive strength is obtained by comparison, and the character to be input is displayed on the screen according to the pressing time of the finger on the button with the highest intensity of the induction. The system 10 for prompting input characters by using a button sensor mainly includes a sensing strength calculation module 100, a time calculation module 11A, and a display module 120. The sensing intensity calculation module 100 is configured to calculate the sensing of the sensor under each button touched by the finger when the user's finger touches the mobile device keyboard 12, such as the touch area 36 in FIG. Strength, and by 8 201012179 comparison to find a button corresponding to the maximum induction intensity. For example, when the finger touches four buttons of “5”, “6”, “8”, and “9” at the same time, the sensing intensity calculation module • 100 calculates the sensing intensity of the sensor under the four buttons (such as pressure). Degree, temperature (high and low), and by comparison to find the button "5" corresponding to the maximum intensity. The time calculation module 110 is configured to calculate a time when the finger is pressed on the button corresponding to the maximum intensity. The display module 120 is configured to display characters of the 按键 button according to the calculated pressing time. For example, the default character display order corresponding to the button "5" is "5, J, K, L...". The user can preset that when the finger presses the button "5" for 1 second, the character "5" is enlarged in the mobile device display area 30; when the button "5" is pressed for 2 seconds, the character is enlarged on the mobile device display area 30. J"; when the button "5" is pressed for 3 seconds, the character "K" or the like is enlarged on the mobile device display area 30. The pressing time can be set according to actual needs. The system 10 for prompting input of characters by using a button sensor further includes a speech module 130 for voice prompting the user to input characters. By using the above display module 120 and the voice module 130, the user can see the characters displayed in the enlarged manner or the characters that hear the voice prompt, thereby judging whether or not the character is required to be input, so as to reduce the input error. Fig. 2 is a flow chart showing the operation of the method for inputting characters by using a key sensing method of the present invention. In step S201, when the user needs to send a text message or make a call, the user touches the keyboard of the mobile device. When the finger touches the keyboard 12, the feeling under the touched button 9 201012179 The sensor simultaneously senses a pressing signal. The time calculation module 110 starts timing to obtain the pressing time of the finger. Step S202, calculating the sensing intensity of the sensor under each of the keys touched by the finger. For example, when the finger touches four buttons of “5”, “6”, “8”, and “9” at the same time, the sensing intensity calculation module 100 calculates the sensing intensity of the sensor under the four buttons (such as the pressure intensity, Temperature level). In step S203, by comparing and confirming a button corresponding to a maximum intensity, in the preferred embodiment, the sensing intensity calculation module 1 finds that the button corresponding to the maximum sensing intensity is "5" by 10 comparison. . In step S204, the current character is enlarged and displayed according to the pressing time of the finger on the confirmed button and the default character display order of each button. In step S205, the user confirms or cancels pressing the button according to his own needs to input the corresponding character or discard the input character. In step S204, the currently displayed character can also be presented by means of a voice prompt. Fig. 3 is a schematic diagram showing an enlarged interface of a user input character. In the figure, the display area 30 magnifies the current character "5", and the input character "1234" is displayed in the bottom area 32 of the display area 30. The pressing area 36 simultaneously touches four buttons of "5", "6", "8", and "9". In other embodiments, only one sensor may be mounted in the mobile device 1, the sensor being coupled to the keys of the keyboard 12. When a finger touches a button on the keyboard 12, each of the touched keys will send a press signal to the sensor. The sensing intensity calculation module 100 calculates the sensing intensity of the plurality of pressing signals sensed by the sensor, and confirms the button corresponding to the maximum sensing intensity by comparing with 201012179. Finally, according to the pressing time of the user's finger on the confirmed button and the default character display order of each button, the current character is enlarged or voiced to facilitate the user's operation. • In summary, the present invention complies with the patent requirements of the invention and submits a patent application according to law.
