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

the disappearing UI trick
egocentric interaction
a physical-virtual design
perspective (Pederson, 2003)
a situative physical-virtual space model
based on popular cognitive science view:
what we see is what we (will) do
– true for direct manipulation in
WIMP
– true for real world
physical-virtual
artefacts
Magic Touch system
(Pederson, 2001; 2004)
dual purpose:
– as filtering model for activity
recognition in physical-virtual
systems
– as design tool for system
developers

potential system functions
system components
• (physical and virtual) object logistics
support
• private black box (inspired by Intel
Personal Server concept)
• activity sequence support
• egocentric interaction sensor pool
• physical-virtual gap bridging support
• physical-virtual OS
• provide ubiquitous access to virtual
environments and objects
• physical objects
• provide manual search and recall of
previously performed activities
• virtual objects (and devices
providing access to them)
• allow for end-user programming of
everyday physical-virtual environments
• extension of the user’s senses
• private black box UI (running on
dedicated device or generalpurpose computing device)
