Sujet : Input Devices and Techniques: Multi-DOF, Multi-hand, Multi-stream, Multi-functional, and Multi-modal

Abstract :
In this talk I will review some of the research my colleagues and I have done on computer input devices and interaction techniques, including the following:

Multi-DOF input: I will discuss a few basic design dimensions in 6 degrees of freedom input devices: isometric vs isotonic resistance; arm, wrist and finger use; and position vs rate control. I will also present a method of quantifying co-ordination of multiple DOF and the use of semi- transparency for effective feedback in 3D.

Multi-hand input: I will emphasize the cognitive benefit of two handed input and describe a two handed, "virtual bulldozer" interface for navigation in virtual worlds.

Multi-stream input: Research on dual stream scrolling and pointing.

Multi-function: from pointing to steering. Traditional input devices are designed for pointing tasks which can be well modelled by Fitts' law. Trajectory-based tasks, or steering, has become an increasingly common element in input but lacked a theoretical model. I will describe how a "Steering law" is devised and applied in the same spirit as Fitts' law, and how the two laws are related.

Multi-modal input: It has been long believed that HCI should be multi-modal. The difficulty lies in seamlessly integrating the multiple modalities. Manual And Gaze Input Cascaded (MAGIC) pointing is one such effort, which implicitly utilizes the fast and effortless eye movement to reduce manual control effort in pointing.

Background : Shumin Zhai is a Research Staff Member at the IBM Almaden Research Center where he conducts research and development of innovative input devices, interaction techniques, performance modeling of human computer interaction, advanced graphical user interfaces, and eye-tracking-based next generation multi-modal interaction techniques. In the past three years he has led the research and development of the IBM ScrollPoint (I and II) Mouse. He received his Ph.D. degree from the University of Toronto where he worked on 3D interfaces and 6 degrees of freedom input control. His publications can be found at www.almaden.ibm.com
