– metrics: completion time and degree of damage<br />

• Task:<br />

– “pick and place” fragile grape in virtual environment<br />

• Feedback modes:<br />

– vibration, colour, and sound<br />

• Participants:<br />

– control group (12), vibration group (12)<br />

– practice + 6 trials over 3 sessions in one week<br />
