Title:
ACTIVE TEXTURE PRESENTATION APPARATUS BASED ON HIGH-DENSITY FLEXIBLE ELECTROMAGNETIC COIL ARRAY DRIVING
Document Type and Number:
WIPO Patent Application WO/2020/211305
Kind Code:
A1
Abstract:
A texture presentation apparatus (2) based on high-density flexible electromagnetic coil array driving, comprising a surface layer (4) and a driving layer (5). The surface layer (4) is in direct contact with fingertips of fingers (1), thereby ensuring the safety of user interaction; moreover, the friction feeling generated when the fingers (1) perform contact sliding can be regulated, and the effect of shielding and protecting the internal driving layer (5) is achieved; the driving layer (5) comprises an extensible soft substrate (9) and a plurality of micro driving units, each micro driving unit can be independently controlled, and the driving layer (5) achieves adjustment of the microscopic geometrical morphology of the texture surface; the texture presentation apparatus (2) can realize multi-scale fine texture presentation; when the fingertips of the fingers (1) make contact with the surface layer (4); the texture presentation apparatus (2) can change, according to different surface textures of surface attributes of an object to be simulated in a virtual environment, texture geometric features presented by the texture presentation apparatus (2) in real time by controlling each independently controlled micro driving unit in the driving layer (5), thereby realizing macroscopic, mesoscopic and microcosmic multi-scale fine texture simulation.
