Compared with the prior art, the touch screen type input terminal greatly improves the use function and practicability, and can meet the needs of different users. [Embodiment] Referring to FIG. 1, FIG. 2 and FIG. 3, the computer system of the present invention comprises a processor 10 and a touch screen control module 11 connected thereto, a monitor module 12 and an input/output interface 13. The processor 10 can use a DSP (Digital Signal Processor) or a SOC (System on a Chip) chip to manage and coordinate each module. The processor 10 can be placed in a host 15, as shown in FIG. The processor 10 can also be solidified in the touch screen control module 11 such that the touch screen control module 11 becomes a self-configuring control module, as shown in FIG. The monitor module 12 displays the information entered by the user. The input/output interface 13 connects the touch screen control module 11 to the monitor module 12, and the information sent by the touch screen control module 11 is processed by the processor 10 and transmitted to the monitor module 12. Referring to FIG. 4 , FIG. 5 , FIG. 6 , FIG. 7 and FIG. 8 , the touch screen control module 11 is provided with a function strip 23 . After the user touches the function strip 23 , the computer system is on the monitor module 12 . The user is prompted to make a mode setting, and the default mode is set to a touch screen keyboard 20. The touch screen keyboard 20 can be set with a country key, and different national keyboards are selected according to different national language 7 200915148. The touch screen control module u has the following function modes: touch screen keyboard mode 2 多, multi-touch screen mode 40, and multi-touch screen plus keyboard mode 5 〇. The touch screen control module 11 includes at least two of the above functional modes. The touch screen keyboard 2 includes a keyboard mode % and a keyboard and mouse mode 26. The multi-touch screen 4〇 can detect the multi-touch of the touch screen control=module 11 at different positions at the same time. (4) Proximity touch device is implemented by the Wei (the mouse, the tablet, the touchpad and the touch screen). ) the input function. Figure 5 shows the keyboard mode 25 of the touch screen keyboard 20. Figure 6 shows the keyboard and mouse material 26 of the touch screen keyboard. ® 7 shows the home screen 4 (). Figure 8 shows the multi-touch screen plus keyboard mode 5〇. The function bar u is provided in any of the input modes of the touch screen control mode, 'and 11. The user can choose to enter any of the above-mentioned round-robin modes, that is, switch between all the functional modes of the screen-controlled dragon group u. Referring to FIG. 9, any input mode of the touch screen control module u is further provided with a reset button 22, and when the user touches the reset button 22 on the touch screen control module 11, the computer system is on the monitor. The module U prompts whether to perform a hardware reset. If the hardware reset is performed, the touch control group 11 restores all settings to the preset value of (4). If the user does not select a hardware reset, the touch screen control module U will restore the set value at the last startup. Referring to FIG. 5, FIG. 10 and FIG. 5 simultaneously, the touch screen keyboard 8 200915148 20 has a plurality of input buttons 21, and the touch screen control module 11 can adjust the size of the button 21 according to the size of a touch object. First, the user clicks the button size adjustment mode on the function bar 23 to enter the button size adjustment state of the touch screen control module u. Thereafter, when the user touches the button 21, a pair of touch points corresponding to the button 21 are generated on the touch screen control module u, and the processor 1 adjusts the size of the button 21 according to the size of the detected touch point. Figure U shows a Cochlear coordinate system. On the touch screen control module u, a touch of the finger is used to represent the touched area, which is a touch point 60. The touch screen control module first recognizes the touch signal, and the processor 10 can obtain the center position and radius of the touch point 6〇, that is, the size of _hard 6() is obtained. The touch screen control module U adjusts the size of the button 21 according to the radius of the touch point 2 obtained by the processor 1 to adapt to the size of the touch object. But not all touch events generated by touch are valid. When the radius of the _ touch point generated by a certain touch object is less than the preset critical radius value of the computer system, (4) is the benefit of the (4) event, and cannot cause any instruction action inside the computer. The touch event is considered to be valid only when the radius of the oscillating object is greater than the critical radius: in addition, the processor is configured to detect the time touch event (four) time is greater than the detection time, the process is the touch event Valid; otherwise, if the touch event lasts for the detection time, the touch event is considered invalid. ^ The user touches the (4) proximity read key on the Lang-type key G ^ 200915148: The second touch screen control module 11 first recognizes the seat of the touch point, for example, (xl, yl), and simultaneously recognizes the adjacent Two by two votes, for example, (仏切, (473), the distance between the treatment - the difference between (Xl, yl) and (x2, y2), and (χ1, (1) and (x3, y3) The distance between the two distance values is compared, '= the small one represents the distance, and the first (4) 1G thinks that the button selected by the touch point is the button closer to the touch point. ^See Figure 12 When the user holds the 'before touch' on the touch screen control module 11, the processing benefit 10 first finds the position of the current effective touch, and calculates the distance between the current effective touch position and the last valid touch position within a predetermined time. , determining whether the distance is less than a preset minimum distance value, and if so, the touch event is a continuous touch event from the last touch event; if the distance is greater than a preset minimum distance value, the touch is a New independent touch event. See Figure 13 The touch screen keyboard 20 can be resized according to the user's needs. Using the finger to move toward the central area of the touch screen keyboard 2, the touch screen keyboard 20 as a whole is enlarged. Moving away from the central area of the 5H touch screen keyboard 20 The touch screen keyboard 20 as a whole is reduced, which is convenient for the user to use. Please refer to FIG. 14 'The user can customize the keyboard according to the habit of using the keyboard. First enter the key layout custom mode (select this on the function bar 23) Mode), the touch screen control module 1]L displays a brand new blank keyboard 'At this time, touch an empty button position', the system prompts to input the character symbol you want to input here, input it into 10 200915148 and save it. When all the keys have been defined, the processor 10 performs an extra key check.
