Vista uses data from a position and orientation sensor on the HMD to update the student s view as they move around. Students interact with the virtual world using a 3D mouse or data gloves. Sensors on the mouse and gloves keep track of the student s hands, and Vista software sends out messages when the student touches virtual objects.
These messages are received and handled by the RIDES software which controls the behaviour of the virtual world. Steve requires two capabilities Steve must be able to demonstrate and explain tasks, and he must be able to monitor students performing tasks, providing assistance when needed.
