Egocentric interaction as a tool for designing ambient ecologies—The case of the easy ADL ecology

A Smart Home Experience Using Egocentric Interaction Design Principles

“…• Explorative system design processes like the easy ADL home design [2,3] are influenced by many uncontrollable variables making it hard to conclude that a certain prototype implementation became better or worse than another due to the underlying design approach only.…”

“…The majority of these virtual objects were designed to facilitate the execution of three variations of everyday home scenarios that were deliberately provocative explorations of what could potentially be possible and useful in the future, rather than minor extensions to common scenarios of today. 9 smart objects with interactive mediators and 42 smart objects with sensor motes were embedded into a 54 m2 apartment effectively forming a living laboratory [2,3] complemented by three wearable mediator smart objects: two bracelets for hand gesture based virtual object manipulation and one Bluetooth wireless headset enabling speech based manipulation and audial perception. The 9 smart objects acted as multimodal mediators by being equipped with LCD displays (except the wall smart object where a projector was used) of varying dimensions for visual perception of virtual objects and a pair of audio speakers for audial perception.…”

“…This paper attempts to explore the human experience that egocentric interaction principles offer within a smart home context. While human experience focusing on the physical-virtual equity principle was already explored in our earlier work [2], the work presented in this paper views egocentric interaction design principles as a whole within the easy ADL home [2,3], a living laboratory smart home for ubiquitous computing research. Considering the scope of this paper, further information about the technological details in developing the easy ADL home including the sensing, communication and interaction infrastructures are described elsewhere [2][3][4][5].…”

While existing work on human experience evaluation have typically focused on mobile computing environments, this work is novel in porting human experience evaluation to ubiquitous computing environments offering additional challenges and contributing along the experimental lines.…”
