Evaluating an Early Motion Planning Feedforward Sensorimotor Mechanism for 2D Sketching

Movement-based interactive systems, and gesture recognition in general, can contribute to the human learning of motor skills. This paper presents the design and initial evaluation of a sensori-motor learning mechanism that provides on-line feedforward to the user when s/he repeats a gesture. This mechanism is based on real time statistical comparison between the input and reference gesture as well as on early motion planning principles that generate the feedforward. It has been implemented for improving the motor control in 2D sketching. 14 participants were appointed to evaluate whether this mechanism has the ability to impart motor skills.
