The VHB

(Virtual Haptic Back)

Through practice on the VHB, students improve their ability to localize areas of abnormal tissue texture within the paraspinal musculature of a realistic, simulated human back.

The location of the abnormality varies randomly between trials. Trials start with obvious abnormalities       (easy) and get progressively more subtle. Users get immediate voice feedback as to the correctness of their localizations. If they are incorrect they are given an opportunity to go back and palpate the problem area.
