System and method for increasing identification rate of handhold-device touch type keyboard

Abstract

The invention discloses a system and a method for increasing an identification rate of a handhold-device touch type keyboard. The method comprises the steps of: setting a corresponding fuzzy set for each virtual key on the touch type keyboard, storing the fuzzy sets in a storage device; receiving a coordinate value of a touch point on a touch screen in real time when the touch type keyboard is displayed on the touch screen; determining a received virtual key that corresponds to the received coordinate value, triggering a function of the received virtual key; determining an adjacent virtual key that has an x coordinate value range overlapping with that of the received virtual key; and modifying the fuzzy set of the received virtual key or the fuzzy set of the adjacent virtual key when a backspace key and the determined adjacent virtual key are received in sequence after the received virtual key, and restoring the modified fuzzy sets. By adopting the system and the method of the invention, the identification rate of the handhold touch type keyboard can be increased.

Description

technical field [0001] The invention relates to a system and method for improving the recognition rate of a hand-held device touching a keyboard. Background technique [0002] Touch-screen handheld devices have been favored by more and more people. Most touch-screen handheld devices use touch-type keyboards as receiving devices. The touch-type keyboard has the characteristics of thinness and fast response, replacing the previous mechanical keyboard. However, due to the fast response speed of the touch keyboard, it is easy to cause insufficient recognition rate. This is mainly because when people operate the touch-type keyboard, most of them operate with their fingers, and the size of the fingers is generally greater than the size of each virtual button on the touch-type keyboard, causing people to expect the button to be pressed to be different from the actual touch button. There is a partial gap at the point of contact. Therefore, it is very important to improve the recog...

Problems solved by technology

[0003] At present, some existing solutions are used to improve the recognition rate. For example, the first method is to set the size of the contact area and then judge the finger contact point. Although the method can improve the recognition rate, firstly, the finger must be pressed with a certain force to judge, which will have a considerable impact on the sensitivity of the keyboard. Second, after the finger is pressed beyond a certain area, the panel may still misjudge the contact point, resulting in The resolution is still insufficient

Method 2: Reduce the effective area of ​​contact. This method is to simulate the gap between real keyboards, so that the finger must touch the "specific area" before it can be judged. However, although this method is helpful to the recognition rate, the sensitivity will be affected accordingly. drop, so people have to get used to these touch positions to find the key they want to press, which is not convenient
