Seminar interaction techniques for high resolution displays (PowerWall)


Prof. Dr. Harald Reiterer

Vorbesprechung am 26.04.06, 12:00 Uhr in D247. Abschlusspräsentationen am 1. August, ab 9:15 Uhr in C202 (Ende gegen 15 Uhr).


Large, high resolution displays do not only provide new possibilities for information visualization and exploration in several application fields but also challenge the user in new and uncommon ways. Due to display dimensions of several meters and enormous information density, the user is only able to perceive a subset of the visualized data at once. The mapping of conventional interaction techniques like WIMP and the use of classical input devices appears to be not sufficient in respect to usability and ergonomics. For instance, pointers are either too small to perceive from all user positions or they don’t react precisely enough on high data density. The remarkable distances which come with direct manipulative interfaces on large displays enforce efficient and exact control mechanisms. Therefore, one topic of the seminar will be the analysis of miscellaneous input devices (tracking systems, PDA, Revolution-Controller…) for high resolution displays in respect to their advantages and disadvantages in combination with several interaction techniques, especially Zoomable User Interfaces. Furthermore, the focus of the seminar lies on new or adjusted interaction concepts for high resolution displays which take the limited human perception into account. You discuss the concepts critically, make suggestions or develop new ideas.

Preliminary Seminar Topics

Topic Field: Input Devices

  • Overview - Input Devices for HRDs
  • Laser Pointer Interaction
  • PDA & Powerwall

Topic Field: Interaction techniques

  • Interaction with HRDs - Possibilities, Challenges, Difficulties. Are ZUIs suitable?
  • Handle the wall - interaction concepts for wall-sized HRDs
  • Interaction Techniques beyond point & click and fixed menus
  • ZoomWall - Unifying physical and virtual navigation

Topic Field: Application Domain

  • Collaborating around large interactive displays
  • Interactive Ambient HRDs






A written elaboration as well as a presentation at the end of the semester has to be done by the students. The final score is a combination of the presentation of about 45 minutes and the written work of about 10 pages (in english or german) in UIST format. Every participant will report on his progress in regular intervals. The topics and amount will be adjusted to the current study level (B.Sc./M.Sc.).
