Next week I presenting a seminar in the
University of Konstanz, Germany as an invited speaker by Professor Harald Reiterer
Abstract:
The computational and contextual edifice around which we will build
our ubicomp user interfaces is complex and constantly changing. This
context include physiological, environmental and computational state. In
this regard, can we model the physiological differences between people
and use the models to adapt and personalize designs, user interfaces and
artefacts? Can we model, measure and predict the cost of users altering
their gaze in single or multi-display environments? If so, can we
personalize interfaces using this knowledge. What about when moving and
while the distance between user and screen is varying. Can this be
considered a new modality and used to personalize the interfaces along
with physiological differences and our current gaze. In this talk we
seek to answer some of these questions. We define Ubicomp User
Interfaces and introduce an Individual Observer Model of human eyesight,
which we use to simulate 3600 biologically valid human eyes. We also
report on controlled lab and outdoor experiments with real users. This
is to measure both gaze and distance from the screen in an attempt to
quantify the cost of attention switching along with the use of distance
as a modality. In each case, for distance, gaze or expected eyesight we
would like to develop models which can allow us to make predictions
about how easy or hard it is to see visual information and visual
designs, along with altering the designs to suit individual users based
on their current context.
