Notebook computer handwriting recognition method and handwriting input system

Abstract

The invention relates to the technical field of handwriting recognition and discloses a notebook computer handwriting recognition method and a handwriting input system. The handwriting input system comprises a sonic signal processing module, a trail tracking and optimizing module and a character recognition module, wherein the sonic signal processing module is connected with the trail tracking and optimizing module and is used for collecting sonic signals given out by built-in audio devices and outputting corrected sonic signals, the trail tracking and optimizing module is connected with the character recognition module and is used for outputting optimized hand movement trails in a plane of a virtual wordpad, and the character recognition module is used for character recognition of the hand movement trails. The handwriting input system has the advantage that the built-in audio devices including two loudspeakers and a microphone in an existing notebook computer are used for providing the sonic signals and capturing the sonic signals to obtain the user hand movement trails on the virtual wordpad, so that character recognition input is achieved finally.

Description

technical field [0001] The invention relates to a technology in the field of handwriting recognition, in particular to a notebook handwriting recognition method and a handwriting input system thereof. Background technique [0002] Human-computer interaction applications based on touch screens are playing an increasingly important role in daily life. However, notebook computers, one of the most widely used mobile devices in people's work and life, cannot use this type of application due to hardware limitations, but on the other hand, wireless control and trajectory tracking technology based on notebook computers can improve Possibility to deploy such applications on laptops to optimize user experience. [0003] Regarding the wireless control and trajectory tracking technology of commercial notebook computers, it can be roughly divided into sound wave control type, image control type, network signal control type and motion sensor control type. There are two main problems in ...

AI Technical Summary

Problems solved by technology

There are two main problems in the above four technologies, one is to require a specific use environment, and the other is to have certain requirements for hardware equipment, among which: the sound wave control trajectory tracking technology requires audio equipment at a specific location to provide sufficient sound wave signals ; Image-controlled trajectory tracking technology requires a suitable lighting environment and has strict requirements on equipment; network signal-controlled trajectory tracking technology requires a large number of wireless signals in the user's environment, or needs to carry a special wireless signal generator; Sensor-controlled trajectory tracking technology requires users to purchase and wear special motion sensors
