Abstract:

This project investigates the ability of virtual human models to simulate human task performance. A variety of reaching tasks were performed by human subjects and their corresponding virtual human using Transom Jack Software. Transom Jack was able to accurately simulate grasping behaviors for approximately 75 of the trials. The most accurate levels were found at waist and acromion shoulder heights. There were significant underestimations for reaches at stature head height and significant underestimations for reaches at knee height. Conversely, an overestimation of reach can have more serious implications. In nearly half of the trials at knee height, Transom Jacks simulation outreached the human subjects. Nonetheless, virtual humans provide valuable information in many situations and the technology is rapidly improving.
