grasping the bytes: morphology of interaction 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.

About me

quick introduction

1998-2005. A brief introduction in powerpoint. Part of a curriculum on emerging trends in interactive information technologies

TML: a testbed for fluid interaction

20/10/2005 TML is a drawing editor experimenting with fluid interaction techniques and full screen user interface. This combines a range of quickly implemented user interface techniques inspired from past research, such as work on the hotbox, Ligne Claire, toolglass and magic lenses.

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

1991-1995 Thèse de doctorat. 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

1992-1994 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
