A demonstration of dynamic drawing guidance via electromagnetic haptic feedback

Abstract

We demonstrate a system to deliver dynamic guidance in drawing, sketching and handwriting tasks via an electromagnet moving underneath a high refresh rate pressure sensitive tablet presented in [3]. The system allows the user to move the pen at their own pace and style and does not take away control. Using a closed-loop time-free approach allows for error-correcting behavior. The user will experience to be smoothly and natural pulled back to the desired trajectory rather than pushing or pulling the pen to a continuously advancing setpoint. The optimization of the setpoint with regard to the user is unique in our approach.
