Usability of optically simulated haptic feedback
In this contribution a method will be described to optically simulate haptic feedback without resorting to mechanical force feedback devices. This method exploits the domination of the visual over the haptic modality. The perception of haptic feedback, usually generated by force feedback devices, was simulated by tiny displacements on the cursor position relative to the intended force. The usability of optically simulated haptic feedback (OSHF) was tested experimentally by measuring effectiveness, efficiency and satisfaction of its users in a Fitts type target-acquisition task and comparing the results with the usability of mechanically simulated force feedback and normal feedback. Results show that OSHF outperforms mechanically simulated haptic feedback and normal feedback, especially in the case of small targets.
