morphology of interaction

...is the depiction of the process by which physical input signals are transformed into information and vice-versa. I worked in this area mostly during my PhD and my time at SGI and Alias|Wavefront, from 1990 to 1998.

aspects morphologique de l'interaction homme-machine: étude de modèles d'interaction gestuels

Une Thèse. english abstract. The morphology of Human-Computer Interaction is the description of the elementary actions of use of a computerized information processing system. An interacting user triggers input devices, which emit signals interpreted by the system. These signals are processed and grouped as events, autonomous entities corresponding to elementary modifications of information objects. We intend to describe these entities, from the perspective of the user producing them, as well as from their integration in the system.

charade, free hand-gestures

The machine was rather difficult to operate. For years, radios had been operated by means of pressing buttons and turning dials; then, as the technology became more sophisticated, the controls were made touch sensitive ... now all you had to do was wave your hand in the general direction of the components and hope. It saved a lot of muscular expenditure of course, but meant you had to stay infuriatingly still if you wanted to keep listening to the same programme. D. Adams, 1979

TML is a small sample of innovative interaction techniques. It's a drawing program with a radically minimal user interface, which tries to express the concept of "Fluidity" in user interaction. This program is dedicated to Manuela. Dean Rubine's gesture recognition code/code source des algorithmes de reconnaissance de geste de Dean Rubine.
