A new algorithm RAV (reparameterized angle variations) is proposed which makes explicit use of trajectory information where the time evolution of the pen coordinates plays a crucial role. The algorithm is robust against stroke connections/abbreviations as well as shape distortions, while maintaining reasonable robustness against stroke-order variations.(More)
We present a study on using a smart phone as a tool to evaluate anticipatory postural adjustments (APA) before the beginning of normal gait in healthy subjects. The results show a significantly lower amplitude of anticipatory postural adjustments in the mediolateral axis (ML) when subjects used the non-dominant leg for the first step compared with the(More)
