Abstract
Due to the miniaturization of projection technology it is
now possible to integrate a projection unit into a mobile
phone. These so called projector phones have the ability to
project and explore large information spaces. On modern
mobile phones the exploration of such information spaces is
connected to panning and zooming, this could be eased with
a projected interface. The size of the projection depends on
the distance between the projection area and the projector
phone. However, to create a projected area of a decent size
one has to be at a certain distance from the projection. This
distance makes direct interaction with the projection in a
single user scenario impossible. This leads to a smalldistributed
user interface where on the one side is the
device with in- and output capabilities and on the other side
the large projection. In this paper, we present an interface
design approach that tries to cover common problems that
arise from the distributed user interface of a projector
phone. Therefore we utilize the dynamic peephole
metaphor. We introduce a prototype of a map application
that implements the proposed design ideas and validates
that the design simplifies mobile map navigation.
