Abstract

The invention discloses an environment information sensor based on vibration touch, belonging to the field of man-machine interaction of blind navigation. The sensor comprises an image collecting module, a movement sensor, a vibrating module, a central processing module and a power supply, wherein the image collecting module uses a CMOS (Complementary Metal Oxide Semiconductor) binocular camera, the image collecting module and the movement sensor respectively provide environment image information and movement information to the central processing module, the central processing module processes and synthesizes the two pieces of information so as to obtain a drive signal for controlling the vibrating module to vibrate and giving a user touch prompts. The environment information sensor based on vibration touch is used for detecting and expressing the environment information in real time based on a touch representation technology and providing an effective solution for the environment perception of the blind or amblyope through relative small equipment by feeding back the prompts by vibration touch.

Description

technical field [0001] The invention relates to a force-tactile human-computer interaction device, in particular to a vibration-tactile-based blind navigation human-computer interaction device and an interaction method thereof, belonging to the field of blind navigation human-computer interaction. Background technique [0002] Virtual reality technology is a research hotspot at home and abroad, and tactile reproduction is an important part of it. With the deepening of research, more practical research will be carried out on tactile reproduction. [0003] A very important tactile feature of an object is that it has surface texture information, and people can get this feeling by touching the object. In the field of virtual reality or teleoperation, reproducing virtual or distant object texture information and acting on the operator's hand can not only enhance the sense of presence of the system, but also help the operator identify virtual objects with different characteristics...
