Embodiment 1

[0083] refer to figure 1 , propose the character input method of the first embodiment of the present invention, described method comprises the following steps:

[0084] S11. Receive the trajectory data sent by the trajectory data acquisition device.

[0085] S12. Determine the start point and end point of each stroke according to the trajectory data.

[0086] S13. Connect the starting point and the ending point of each stroke to draw a character image.

[0087] S14. Match the corresponding character in the character library according to the character image.

[0088] In the embodiment of the present invention, the trajectory data acquisition device (such as a stylus) establishes a communication connection with the virtual reality device through wireless (such as Bluetooth, WIFI) or wired mode, and the user can hold the trajectory data acquisition device to write in the air, and the trajectory data acquisition device The trajectory data is collected by sensors such as a gyros...

Embodiment 2

[0147] refer to Figure 5 , the character input device of the second embodiment of the present invention is proposed, the device includes a receiving module, a determining module, a drawing module and a matching module, wherein:

[0148] Receiving module: used to receive the trajectory data sent by the trajectory data acquisition device.

[0149]Specifically, the receiving module can receive the trajectory data sent by the trajectory data acquisition device through wireless communication or wired communication. The track data is track data generated when the user writes characters.

[0150] Optionally, the trajectory data acquisition device may collect trajectory data in the following manner: receiving the first instruction and the second instruction; when receiving the first instruction, start recording the data of the gyroscope; when receiving the second instruction, stop recording The data of the gyroscope: the data recorded between the first instruction and the second in...

Abstract

The invention discloses a character input method and device. The method comprises the steps that trace data sent by a trace data collection device is received; the starting point and the ending point of each stroke are determined according to the trace data; the starting point and the ending point of each stroke are connected to draw a character image; and a corresponding character is obtained through matching in a character repertoire according to the character image. According to the character input method in the embodiment, the trace data sent by the trace data collection device is received, the starting point and the ending point of each stroke are determined according to the trace data, the character image is drawn, finally the corresponding character is obtained through matching in the character repertoire according to the character image, and therefore character input is realized. The whole input process is similar to hand input and meets the writing habit of a user at ordinary times, operation is extremely convenient and fast, input efficiency is improved, the technical problem that it is inconvenient to input characters into virtual reality equipment and other terminal equipment is solved, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a character input method and device. Background technique [0002] Virtual reality equipment, referred to as VR (Virtual Reality) equipment, is a product that uses simulation technology, computer graphics, human-machine interface technology, multimedia technology, sensor technology, and network technology. Created a brand-new means of human-computer interaction. Its specific technical connotation is a technology that comprehensively utilizes computer graphics systems and various interface devices such as reality and control to provide an immersive feeling in an interactive three-dimensional environment generated on a computer. [0003] Since VR devices are not convenient for character input via keyboard or touch, various VR devices are faced with the problem of how to implement character input. The existing solution is to display a virtual keyboard in the VR interface, ...
