4.2 Some Examples of Interesting Research Activities

Integrated Design of Smart Environments

• Swisshouse Program
  I thought they were building an interesting house somewhere in Boston. They probably talked about their visions at the 2nd International Workshop on Cooperative Buildings.
  
• The Adaptive House, Boulder, Colorado
  Michael Moser's group have constructed a prototype of a control system in an actual residence. The house is equipped with many sensors and actuators. The system which is based on neural network techniques etc. learns to manage heat, water, air heat, lighting and ventilation.
  
• Augmented Surfaces
  Developed at Sony CSL. A computer augmented environment allowing for spatially continuous operations across portable computers, table and wall displays, and other physical objects (videotapes, document folders, etc.). A window on a portable computer jumps out onto a table display (Hyperdragging) and the other way around. Pick and Drop operations can be done using Laser pointers. Digital Attachment links physical object like book pages to related digital objects. PropCamera on a table display creates 3D views on a wall display. [They also used a similar hardware environment to create Baseball Watching Station, assigning different kinds of information (TV broadcast, games, chat systems) concerning live baseball games. Kind of reminds me of the EDC environment at the University of Colorado.]

Unlike common touch sensitive surfaces, the display surface has (infrared) eyes that can see what is going on near the surface. Any objects that reflect infrared lights can be recognized by the system and used as system inputs. Allows for two-handed interaction.

Everyday Objects

• MediaCup
  Developed at TecO, University of Karlsruhe. Cofee cups augmented with sensing, processing and communication. For example, meetings in a room may be detected by monitoring activities of MediaCups.
