From human movement analysis to interface design: applications to writing and gesture based user interface

A number of authors have studied the possibility of using handwriting or gesture as inputs. In most cases, the focus was either on building robust algorithms for recognition or identifying a set of assumed "natural" movements. Few authors have taken the analysis of actual movements as a starting point to build a set of precise and stable movements. This paper presents some arguments in favor of using results from human movement science to improve the elaboration of robust interfaces.
