Multidimensional visual aid enhances haptic training simulations

This paper explores the use of hypotrochoid curves as visual aids for haptic training systems that are used to teach motor skills that require recall of forces and positions at specific locations to replicate the expert touch. The visual aid presented is a multidimensional feedback tool that can provide information on force, position, and velocity simultaneously. The extent of learning is measured by the accuracy of the force recall. A breast haptic simulation was used to test the presented visual aid. Results suggest that multidimensional feedback is an effective way to promote learning of forces. In addition, the presented visual aid made learning an enjoyable process.
