Ambient kitchen

Abstract

The Ambient Kitchen is a high fidelity prototype for exploring the design of pervasive computing algorithms and applications for everyday environments. The environment integrates data projectors, cameras, RFID tags and readers, object mounted accelerometers, and under-floor pressure sensing using a combination of wired and wireless networks. The Ambient Kitchen is a lab-based replication of a real kitchen where careful design has hidden the additional technology, and allows both the evaluation of pervasive computing prototypes and the simultaneous capture of the multiple synchronized streams of sensor data. Previous work exploring the requirements for situated support for people with cognitive impairments motivated the design of the physical and technical infrastructure and we describe both our motivations and previous work on interaction design in kitchen environments. Finally, we describe how our lab-based prototype has been put to use as: a design tool for designers; a design tool for users; an observatory to collect sensor data for activity recognition algorithm development, and an evaluation test bed. The limitations and advantages of lab-based, as opposed to in situ home-based testing, are discussed
