Introduction

A laptop with dual screens is a trend for the coming future. It means typing on an LCD screen displaying dynamic content instead of a fixed physical keyboard is an emergent design possibility. However, the current approach only showing a static keyboard graphically on the screen wastes the potential of a sensible and displayable touch screen. In this research, we are going to design an “Adaptive Typing” mechanism that actively detects user’s hand palm resting on the screen and automatically predicts key locations. This mechanism also provides minimum visual clues to assist novice users. In order to realize this idea, we design an experimental desk to collect and observe users’ mental models and hand ergonomics while typing. As shown in the picture, the upper camera collects data about keys and fingers; the lower camera collects data of hand palms through a transparent part with which a conventional keyboard and a touch pad embedded in. We believe that by overlapping image data of upper and lower cameras, the hidden relationships between hand palm and typing can be further revealed.
