Experimental Design • Experimental Goal: – evaluate vibrotactile, visual, and audio feedback – metrics: completion time and degree of damage • Task: – “pick and place” fragile grape in virtual environment • Feedback modes: – vibration, colour, and sound • Participants: – control group (12), vibration group (12) – practice + 6 trials over 3 sessions in one week May 26, 1997 - CCECE ‘97 Design of a Vibrotactile Feedback Virtual Testbed Li-Te Cheng, Memorial University of Newfoundland
