Reilly, R. B. and O'Malley, M. J. 'Adaptive noncontact gesture-based system for augmentative communication' in IEEE Transactions on Rehabilitation Engineering, 7, (2), 1999, pp. 174 - 182.
An adaptive noncontact gesture-based system for
augmentative communication is described. The system detects
movement of any anatomical site through the analysis of reflected
speckle. This movement is converted into two-dimensional (2-D)
cursor coordinates and an adaptive software interface provides
click actions and decision strategies. The system requires no
accessory to be placed on the user. The system was developed in
conjunction with user groups, who participated in the evaluation
of the system. The usability results obtained illustrate the utility
of the system. The system also compared favorably with other
