• Remote Commander, so members of the meeting can control the cursor and keyboard from their seat without getting up.
  • Issue: Single Display Groupware interaction techniques and implementation (how multiple people can share the same display). (see related papers on UI and implementation)
• SlideShow Commander, so presenter can more easily control the presentation.
• Laser Pointer interaction techniques, for presenter or audience members. (see related conference paper)
• Semantic Snarfing, so audience members can grab (snarf) the interesting parts of the shared display and interact with it. (see related conference paper)
• Private drill down of public information, as investigated in the Command Post of the Future project.
