An fNIR based BMI for letter construction using continuous control

A long term goal of assistive technology research is to build creative expression applications where subjects can extemporaneously express themselves. Sketch drawing is one form of creative expression. In this work, we demonstrate the usability of a brain-machine interface (BMI) for expression using a letter drawing task. We describe empirical results that represent a first step toward assistive applications for creative expression.
