A writing pressure analysis method for evaluation of trail making test using smart device

This paper describes a diagnosis support system for Trail Making Test (TMT). The system imitates paper based TMT by using a tablet PC and smart pencil that can take writing pressure. Any line between two symbols is separated to finding phase and moving phase, and time, length and pressure of these phases are corrected to evaluate patient's higher brain dysfunctions level. In experiment, we corrected TMT data form 6 healthy volunteers and 10 patients. Results shows difference between healthy volunteers and patients.
