Force-feedback directional guidance system and control method combining center-of-mass offset and vibration

Abstract

The invention relates to a force feedback direction guidance system and a control method which are combined by a center of mass deviation and vibration, belonging to the field of human-computer interaction. The system comprises a centroid universal motion unit and a vibration motor unit, wherein the centroid universal motion unit provides centroid offset force feedback, the vibration motor unit provides vibration force feedback, and the rotation haptics and the translation haptics of the vibration motor unit are presented through the centroid offset force feedback. The advantage is that the user can quickly and accurately feel the direction of the target. The tactile sphere is movable, easy to use, and can be used in medical rehabilitation, VR handle, mouse, mobile phone, tablet and otherdevices. The system and method can achieve six degrees of freedom direction guidance in three-dimensional space.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a force feedback direction guidance system and control method combined with center of mass offset and vibration. Through the center of mass offset force feedback, the sense of rotation is presented and the vibration force feedback unit presents the sense of translation. Users can quickly, Accurately feel the direction of the target, the tactile ball is movable, easy to use, and can realize six-degree-of-freedom direction guidance in three-dimensional space, and can be applied to medical rehabilitation, VR handles, mice, mobile phones, tablets and other devices to guide users to realize direction exploration . Background technique [0002] The concept of rehabilitation medicine was born in the middle of the 20th century. It is a medical discipline that eliminates and alleviates human dysfunction, compensates and rebuilds human dysfunction, and tries to improve...

AI Technical Summary

Problems solved by technology

Through vector synthesis, direction guidance with six degrees of freedom in three-dimensional space is realized, but the device is bulky and inconvenient to use, and can only provide vibration force feedback, and the tactile method is single

[0006] Chinese patent application "a comprehensive rehabilitation training platform for hand function" (CN107928989A) The purpose of this invention is to help patients increase their muscle strength, and it is used for comprehensive rehabilitation training of hand functions for upper limb muscle strength rehabilitation training, but a certain venue is required for rehabilitation training. The device is bulky, heavy and does not have portability
