ABSTRACT:
A virtual reality vehicle simulator has a seat for supporting a person in a sitting position. The person wears goggles that present to the person an image of a virtual vehicle, as well as a virtual image of the person's hand and any objects, such as coffee cups, that the person may grasp in his hand. A position sensing system senses the position of a marker that is attached to a marked portion of the person's hand, e.g., the back of the hand. The person may be tasked to manipulate a virtual object, e.g., a virtual pushbutton, with a contact portion of his hand, e.g., the index finger. To calibrate the distance between the marked and contact portions so that a virtual image of the hand accurately may be displayed, a control surface is positioned adjacent the seat such that the person can manipulate the control surface. Based on the manipulation, the distance between the marked and contact portions is determined, thus calibrating the size of the virtual hand to accurately model the person's actual hand.
