Figure 3. Taking a photo of the MobiDiC Coupon display, and user interacting with the iDisplays system

then present the photographs at a participating
shop. Shopfinder is a small companion application
supporting the coupon/advertising system. People
can download it after having taken a photograph
of a coupon in order to get guidance to the shop,
which offers the coupon. They initiate the down-
load by sending the coupon to the display via
Bluetooth Object Push. The display system then
generates a customized Java application and sends
it back to the mobile phone. When users launch
the Shopfinder application, it shows a series of

landmark pictures that help users finding their
way to the shop.

EVALUATION/DEVELOPMENT
METHODOLOGY

Our research approach involves a tight cycle where
theoretical issues and understanding, developed
through our reflection on empirical observations,
are used to design deployed systems that test
and explore the theories (see Figure 4). These
