Abstract

The invention provides a space mouse used for human-computer interaction, and an electromagnetic positioning method, and can lower cost. The method comprises the following steps that: independently obtaining magnetic induction strength measured by a first magnetic induction intensity sensor and a second magnetic induction intensity sensor; and according to a pre-determined position relationship between the first magnetic induction intensity sensor and the second magnetic induction intensity sensor, and the magnetic induction strength measured by the first magnetic induction intensity sensor and the second magnetic induction intensity sensor, determining the position of the space mouse in the space. The method is suitable for a human-computer interaction operation.

Description

technical field [0001] The invention relates to the technical field of electromagnetic tracking, in particular to a space mouse for human-computer interaction and an electromagnetic positioning method. Background technique [0002] In recent years, both spatial positioning and human-computer interaction are topics with a long research history. Space positioning solutions include GPS positioning, IMU positioning, Wi-Fi positioning, base station positioning, etc. Spatial interaction methods include keyboard input, mouse input, and depth camera human motion recognition input. Human-computer interaction solutions at the spatial level include body movement recognition based on depth cameras and image recognition. The advantages of this solution are that the recognition algorithm is mature and the positioning space range is large; The sense of delay and the degree of user experience are relatively limited. [0003] At present, electromagnetic tracking technology is mostly used ...
