Abstract

The invention provides an air input system, a method and air input acquisition equipment and aims to solve the problems that a traditional handwriting input manner has to rely on a handwriting board or a touch screen to acquire and record input tracks, and only two-dimensional plane trajectory data can be converted. The air input acquisition equipment acquires three-dimensional handwriting trajectory data input in a handwriting manner according to handwriting movement tracks of a user and transmits the three-dimensional handwriting trajectory data to terminal equipment; the terminal equipment transmits the three-dimensional handwriting trajectory data to a cloud server terminal; the cloud server terminal projects the three-dimensional handwriting trajectory data to a plane, converts the three-dimensional handwriting trajectory data into two-dimensional handwriting trajectory data for handwriting recognition and transmits recognition results to the terminal equipment; and the terminal equipment executes corresponding operation according to the recognition results. The air input acquisition equipment has the advantages that the handwriting input operation can be carried out under the space environment, and the traditional handwriting board or the touch screen is not relied on; and moreover, the conversion from the three-dimensional handwriting trajectory data to the two-dimensional handwriting trajectory data is realized.

Description

technical field [0001] The present application relates to the technical field of handwriting input, in particular to an air input system, method and air input collection device. Background technique [0002] Common input methods in existing electronic devices include keyboard input, voice input and handwriting input. Wherein the handwriting input device generally comprises two parts: stylus and handwriting board or touch screen, a plurality of capacitors or resistors are set in the handwriting board or touch screen, stylus can be any object that can change capacitance or resistance, when stylus touches handwriting board or When touching the screen, the capacitance or resistance of the corresponding position of the handwriting pad or touch screen changes. By collecting the capacitance or resistance change information on the handwriting pad or touch screen, the change information is identified as an ordered track, and then the ordered track is converted into a Chinese characte...
