Figure 5 is a flowchart showing the processing procedure of the input value feedback method according to the second embodiment of the present invention.

[0051] As mentioned above, when a finger slides on a key, the vibration can be sensed to know which key is being pressed, thereby realizing tactile recognition. No input is generated when the finger touches lightly or slides over the key, and the tapping action of the finger can be confirmed by combining pressure sensing, so that the input is generated only when the finger is tapping. Whether the input is recognized or not is also fed back by a set of vibrations. After inputting (knocking) each time, the user can know whether the input is correct by feeling the vibration.

Abstract

The invention discloses a method for recognizing key positions on a keyboard of a touch screen, a method for feeding back input values on the keyboard of the touch screen and a method for clicking input on the touch screen. The method for recognizing the key positions on the keyboard of the touch screen comprises the following steps that three driving motors are arranged for the touch screen to drive three vibrators different in polarization direction respectively; each time before input, recognizing vibrations different in direction are defined for all keys; pressed keys vibrate in the defined recognizing vibration directions without generation of input when the fingers of a user slide on all the keys, and the user knows the pressed keys by perceiving the recognizing vibrations; clicking actions of the fingers are confirmed with the combination of pressure perception when each key is clicked by the corresponding finger of the user, and thus input is generated.

Description

technical field [0001] The present application relates to a method for identifying key positions on a keyboard of a touch screen, a method for feeding back an input value on a keyboard of a touch screen, and a method for tapping an input on a touch screen. Background technique [0002] Due to the simple design and direct interaction of the touch screen, it has been widely used in various mobile devices. The mobile device with a touch screen greatly saves the space occupied by I / O, reduces physical buttons, and even the whole device is a huge screen, with a wide range of input and output control. This looks very beautiful, but in the process of using, people found some problems, especially when inputting text, the virtual keyboard has no sense of touch. When entering text on the touch screen, you must observe the keys on the virtual keyboard, and then Touching the corresponding keys accurately with your fingers cannot realize touch typing on a mechanical keyboard. This proce...
