Zusammenfassung

Since large, high-resolution displays (LHRD) are capable of visualizing a large amount of very detailed information, users have to move around in front of these displays to gain either in-depth knowledge or an overview. However, conventional input devices such as mouse and keyboard restrict users mobility by requiring a stable surface on which to operate. We present a flexible and intuitive interaction technique based on an infrared laserpointer, a technique that allows identical use from any point and distance. In particular, our laserpointer interaction satisfies the demands of LHRD in the areas of mobility, accuracy, and interaction speed. The solution presented is technically designed as a generic interaction library whose flexibility and general applicability was verified by using it on two very different systems a planar 221" Powerwall and a curved 360° panoramic display. Furthermore, a comparative evaluation study with 16 participants was conducted on the Powerwall to compare the performances of a conventional mouse and our laserpointer by means of a unidirectional tapping test at varying distances (ISO 9241-9). The statistically significant performance advantage of the mouse (13%) appears marginal considering the intuitive and direct mode of interaction in using the laserpointer and the flexibility gained by its use, both of which are fundamental requirements for LHRDs. In comparison to previous systems and evaluations, we were able to reduce the laserpointer s performance lag by over 50%. This result is achieved mainly by our precise tracking method, the minimized delay, and the effective jitter compensation.
