egocentric interaction

1

• egocentric interaction a design framework and
  computing architecture for individual everyday
  activity support
• relation to reality-based interactionincorporati
  ng the real world rather than mimicing it

egocentric interaction
the disappearing UI trick

• a physical-virtual design perspective (Pederson,
  2003)

• a situative physical-virtual space model
• based on popular cognitive science viewwhat we
  see is what we (will) do
• true for direct manipulation in WIMP
• true for real world
• dual purpose
• as filtering model for activity recognition in
  physical-virtual systems
• as design tool for system developers

egocentric interaction

• system components
• private black box (inspired by Intel Personal
  Server concept)
• egocentric interaction sensor pool
• physical-virtual OS
• physical objects
• virtual objects (and devices providing access to
  them)
• private black box UI (running on dedicated device
  or general-purpose computing device)

• potential system functions
• (physical and virtual) object logistics support
• activity sequence support
• physical-virtual gap bridging support
• provide ubiquitous access to virtual environments
  and objects
• provide manual search and recall of previously
  performed activities
• allow for end-user programming of everyday
  physical-virtual environments
• extension of the users senses
