Abstract

The invention discloses a non-contact electrostatic detection method for tracking human hand motion trajectory, belongs to the field of electrostatic detection, and relates to a non-contact method for measuring hand motion speed. The non-contact electrostatic detection method comprises the following steps of distributing a multiple-electrode-plate detection array capable of detecting a human hand motion electrostatic signal; collecting an electrostatic signal in a monitoring environment; comparing the collected electrostatic induction signal potential value with a preset criterion; reading zero-passing time tightly following crest values on each electrode plate; and calculating human hand motion direction alpha and human hand motion speed V according to the detection results, and then tracking the human hand real-time motion trajectory. The invention further discloses a non-contact electrostatic detection method for measuring the human hand motion direction. By means of the non-contact electrostatic detection method, working corner areas of the technology for tracking the human hand motion trajectory can be reduced, and design complex degree of a human hand motion trajectory tracking detection system is reduced.
