Useful Parameters for the Design of Laser Pointer Interaction Techniques

By Choon Hong Peck


This paper reports on some fundamental parameters for the design of wall-based laser pointer interaction techniques. Ten users participated in this study and their laser points were tracked and recorded by a computer. The data collected were then processed and statistically analyzed to provide parameters like the size of the dwell of a laser point, the time taken to acquire a target and the time required to determine a dwell on a target. These numbers are needed when designing interaction techniques that use a laser pointer. KEYWORDS Laser pointer, remote mouse, interaction technology, novel input techniques, Pebbles. INTRODUCTION With the widespread use of projection screens and laser pointers, there has been much research in the area of projection-based multi-user systems using laser pointers as interaction devices (e.g. [1, 2]). However, partially due to the lack of actual user data on the usage of the laser pointing devices, many of these systems are unsuccessful in their imple..
