MobileHCI 2010 Talk on Smart Object Interaction
1. An Explorative Comparison of Magic Lens and Personal
Projection for Interacting with Smart Objects
Fahim Kawsar, Enrico Rukzio, Gerd Kortuem
Lancaster University
2. “A
computa0onally
instrumented
tangible
object
with
an
established
purpose
that
augments
human
percep0on
and
is
aware
of
its
opera0onal
situa0ons
and
capable
of
providing
supplementary
services
without
compromising
its
original
appearance
and
interac0on
metaphor
significantly.”

3. Design Constrains
Form factor and interaction consistency need to be
maintained, limiting the output modalities.
