Motion capture glove for virtual reality system and virtual reality system

Abstract

The invention discloses a motion capture glove for a virtual reality system and the virtual reality system. The motion capture glove comprises a three-finger fingerstall, a glove body, a wrist part and an optical mark; the three-finger fingerstall comprises a first inertial sensor, a second inertial sensor and a third inertial sensor which are respectively arranged at the second knuckles of a first fingerstall, a second fingerstall and a third fingerstall for the virtual reality system to determine the motion information of a first finger, a second finger and a third finger which wear the motion capture glove; the glove body comprises a fourth inertial sensor which is arranged at the hand back of the glove body, and is used for sending the motion information of the fourth inertial sensor for the virtual reality system to determine the motion information of a palm which wears the glove body; the wrist part comprises a fifth inertial sensor which is arranged on the back side of a wrist part, and is used for sending the motion information of the fifth inertial sensor for the virtual reality system to determine the motion information of the wrist which wears the wrist part; the optical mark is arranged on the back side of the wrist part for the virtual reality system to track to acquire an absolute position of the wrist which wears the wrist part.

Description

technical field [0001] The invention relates to the technical field of virtual reality systems, in particular to a motion capture glove used in a virtual reality system and a virtual reality system. Background technique [0002] Motion capture gloves based on inertial sensors in virtual reality systems are usually five-finger motion capture gloves. The second phalanx of the middle finger, the second phalanx of the ring finger and the second phalanx of the little finger are provided with inertial sensors to determine the position and posture of the forearm, palm and corresponding fingers. [0003] In the process of realizing the present invention, the inventors found that the prior art motion capture glove does determine the relative position of the wrist, palm and fingers relative to the elbow; due to the inherent error of the inertial sensor will accumulate during the integration process, resulting in position Drift, thus causing motion capture gloves to be unable to perfo...

[0003] In the process of implementing the present invention, the inventors found that the prior art motion capture glove does determine the relative position of the wrist, palm and fingers relative to the elbow; due to the inherent error of the inertial sensor will accumulate during the integration process, resulting in a position Drift, thus causing motion capture gloves to be unable to perform accurate spatial positioning; moreover, existing motion capture gloves need to install inertial sensors on each finger, which is not convenient for wearing and flexible movement of fingers
