Abstract

The embodiments of the present invention provide a method and an electronic apparatus for realizing virtual handwriting input. The method for realizing virtual handwriting input includes: obtaining, by an electronic apparatus, position coordinates of a handwriting apparatus in a virtual handwriting area through monitoring in a real-time manner, where the virtual handwriting area is an area in which a distance-measuring detector in the electronic apparatus may perform effective distance measurement; obtaining a track formed by the position coordinates, and obtaining a handwriting track of an entire handwriting input process when it is detected that the current handwriting input ends; and identifying a character corresponding to the obtained handwriting track and displaying the identified character. With the method and the electronic apparatus for realizing virtual handwriting input provided in the embodiments of the present invention, handwriting input may be realized simply and conveniently and handwriting input may be realized may be implemented with a low cost.

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...

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 layer of silica glass protective layer, which makes the existing touch screen have defects such as high cost, complicated process, and fear of scratches and damage.

At the same time, when the position coordinates are determined by detecting changes in resistance or capacitance, the problem of non-response of the touch screen will occur. If the problem of non-response is solved by increasing the sensitivity, the cost of the touch screen will be further increased.
