FORCE FEEDBACK FOR VIRTUAL REALITY

A system for producing realistic tactile feedback forces in a tool operation simulator. Sensors (25) sense the location and direction of movement of a simulated tool (11) in a simulated landscape environment to produce electrical signals representing three-dimensional location and direction of movem...

More Information
Summary:A system for producing realistic tactile feedback forces in a tool operation simulator. Sensors (25) sense the location and direction of movement of a simulated tool (11) in a simulated landscape environment to produce electrical signals representing three-dimensional location and direction of movement. These electrical signals are processed by re-programmable processors (28) to produce control signals (30) that are fed to pneumatic bi-directional piston-type actuators (14) to impart realistic forces similar to forces that would be encountered in corresponding real-life movement of the simulated tool (11). Système de création de forces réalistes de rétroaction tactile dans un simulateur de fonctionnement d'outil. Des détecteurs (25) détectent l'emplacement et le sens de déplacement d'un outil simulé (11) dans un environnement simulé afin de produire des signaux électriques représentant l'emplacement tridimensionnel et le sens du déplacement. Ces signaux électriques sont traités par des processeurs reprogrammables (28), de manière à produire des signaux de commande (30) alimentant des organes de commande pneumatiques (14) de type piston à déplacement alternatif afin d'appliquer des forces réalistes similaires aux forces qu'on rencontrerait dans le déplacement réel correspondant de l'outil simulé (11).
