Virtual keyboard key touch transmission method for information identification

Abstract

The invention relates to a virtual keyboard key touch transmission method for information identification, and belongs to the field of man-machine interaction. A mobile terminal device with a touch screen is adopted, a vibration type virtual keyboard key touch information transmission method driven by a single motor or multiple motors is adopted, virtual keyboard key touch operation of a user on a touch screen and text information expressed by keys are obtained in real time, an information instruction is transmitted to a processing unit in a vibration tactile feedback element, an element for providing force feedback is called according to the instruction information, a corresponding vibration tactile signal is applied, corresponding normal vibration feedback is provided, and information is obtained through a finger tactile channel. According to the method, the corresponding vibration effect is generated in a local, half or global mode according to different instruction operations of the keys of a virtual keyboard by utilizing the single or multiple vibration tactile executive elements, a virtual keyboard key model operated by a user is designed, a virtual interface configuration file is written, and the man-machine information communication capability is enhanced.

Description

technical field [0001] The invention belongs to the field of communication systems and human-computer interaction, and in particular relates to a virtual keyboard button tactile transmission method for information identification. Background technique [0002] Touch screen terminal equipment provides a large area of ​​interaction area and is the current mainstream human-computer interaction tool. This is not only an extended application of vision and hearing, but also provides a new transmission method for touch. At present, the tactile feedback effect on the touch screen terminal equipment includes reproducing the tactile sensation of real objects and artificially transmitting tactile information. Reproducing the tactile sensation of real objects includes object surface texture, physical deformation and motion trajectory. This tactile effect processing is mainly to improve human-computer interaction. tactile realism. In order to allow users to obtain information through tac...

AI Technical Summary

Problems solved by technology

Considering that most of the current touch screen terminal devices use motor vibration to increase the tactile effect, but most of the tactile effects that can be realized on the virtual keyboard keys use a single vibration feedback as the user's "click", "press" or "click". The prompt application of "long press" operation fails to achieve the function of transmitting tactile information
