Online Handwriting, Signature and Touch Dynamics: Tasks and Potential Applications in the Field of Security and Health

Advantageous property of behavioural signals (e.g. handwriting), in contrast to morphological ones iris, fingerprint, hand geometry), is the possibility ask a user perform many different tasks. This article summarises recent findings and applications handwriting/drawing tasks field security health. More specifically, it focused on on-line handwriting hand-based interaction, i.e. that utilise digitizing device (specific devoted or general-purpose tablet/smartphone) during realization Such devices permit acquisition on-surface dynamics as well in-air movements time, thus providing complex richer information when compared conventional “pen paper” method. Although scientific literature reports wide range applications, this paper, we summarize only those competitive results terms discrimination power) having significant impact field.
