Embodiment Construction

[0028] The following describes in detail with reference to the accompanying drawings and specific embodiments.

[0029] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the air handwriting system of the present invention. As shown in the figure, the aerial handwriting system 20 includes a stylus 21 and a terminal device 22 . The stylus 21 includes a collection module 210 and a sending module 211 . The terminal device 22 includes a receiving module 221 and an identifying module 222 .

[0030] The collection module 210 is used to collect the effective three-dimensional movement trajectory of the stylus 21 when writing in the air, wherein the effective three-dimensional movement trajectory is the three-dimensional movement trajectory of the stylus 21 when gesturing characters in the air, for example: handwriting "two" in the air, handwriting Three-dimensional trajectory of pen 21 moving in the air Wherein the three-dimensional motion trajecto...

Abstract

The invention discloses a midair handwriting system and a handwriting pen. The system comprises the handwriting pen and terminal equipment, wherein the handwriting pen comprises an acquisition module and a sending module, the acquisition module is used for acquiring effective three-dimensional motion tracks when the handwriting pen is used for writing in the air, and the effective three-dimensional motion tracks are the three-dimensional motion tracks of the handwriting pen when the handwriting pen is used for gesturing the strokes of a character; the sending module is used for sending the effective three-dimensional motion tracks to the terminal equipment; the terminal equipment comprises a receiving module and a recognition module, the receiving module is used for receiving the effective three-dimensional motion tracks sent by the sending module, and the recognition module is used for recognizing the character represented by the effective three-dimensional motion tracks. Through the mode, handwriting input can be free from the limitation of a handwriting board, handwriting input is more free and flexible, and user experience is better.

Description

technical field [0001] The invention relates to the technical field of handwriting, in particular to an aerial handwriting system and a stylus. Background technique [0002] Currently, common input methods for electronic devices include keyboard input, voice input and handwriting input. For handwriting input, a handwriting board must be equipped. The user writes on the handwriting board with a finger or a special stylus, and then recognizes the trajectory of the two-dimensional plane written by the user on the handwriting board. [0003] It can be seen that the handwriting input mode in the prior art must cooperate with the handwriting board to complete the handwriting input, and the handwriting input is limited, and most of the handwriting boards in the prior art are glass products. The lifetime is limited by the number of handwritings. Contents of the invention [0004] The invention provides an aerial handwriting system and a stylus, which can free the handwriting inp...
