Bonjour pour mon tpe je voudrais décrire le fonctionnement de la virtusphère
http://www.virtusphere.com/
Je n'arrive pas bien a saisir comment ça marche...
" VirtuSphere systems are made to client specifications and typically include an easy-
to-assemble sphere, a base platform that enables it to rotate, a head-mounted display,
3D sensors, sphere rotation trackers, a computer, device drivers and 3D software
applications."
"Movement sensors are located on the bottom of the sphere – we use a Doppler-
effect ultrasonic device to track the rotation of the sphere and then translate that to X,
Y coordinates on the plain for the PC. An additional 3D sensor is located on the Head
Mounted Display (HMD) and it tracks the Point Of View (POV) of the user. The HMD
sensor is connected wirelessly via Bluetooth with the PC that runs the application. To
make the sensors work in unison and to process the data to and from the application,
we have our own proprietary algorithms, SuitManager and device drivers."
J'ai émis l'hypothèse que le capteur a effet doppler détectait la vitesse a laquelle tourne les roue et d'une façon ou d'une autre un capteur détectait la direction des roues masi ca reste très imprécis et il n'y a pas de quoi faire mon tpe :s
Pouvez vous m'aider?
