Problems solved by technology

[0004] However, since the above-mentioned touch screen handwriting input technology needs to determine the position coordinates by detecting changes in resistance or capacitance, the touch screen needs to be made of special materials, for example: a resistive touch screen is a four-layer composite glass screen, and the inner surface of the glass screen Each layer of ITO and interlayer is coated with a layer of ITO, and the outermost layer is a thin la...

Abstract

An embodiment of the present invention provides a method and electronic device for virtual handwritten input. The method for virtual handwritten input comprises: the electronic device detecting and obtaining, in real time, position coordinates of a handwriting device in a virtual handwriting region, the virtual handwriting region being a region in which a distance-measuring detector in the electronic device can effectively measure distances; obtaining a trace formed by the position coordinates and, when determining that a current handwritten input is complete, obtaining the handwriting trace from the full handwritten input process; recognizing a character corresponding to the handwriting trace obtained, and then displaying the recognized character. The method and electronic device for virtual handwritten input provided by an embodiment of the present invention enables simple, convenient, and low-cost handwritten input.

Description

technical field [0001] The invention relates to the technical field of virtual handwriting input, in particular to a method and an electronic device for realizing virtual handwriting input. Background technique [0002] At present, there are mainly two character input modes for devices such as mobile phones and handheld computers, namely handwriting input and keyboard input. [0003] Most of the existing handwriting input technologies are implemented by setting a resistive or capacitive touch screen. The implementation process is to detect the user's touch position through the change of resistance or capacitance, and send the touch information to the touch screen controller after receiving it. After receiving the touch information, the device converts it into touch coordinates, and then sends it to the CPU, and the CPU performs corresponding character recognition operations. [0004] However, since the above-mentioned touch screen handwriting input technology needs to deter...
