Device-free interaction in smart domestic environments

This paper contributes to the exploration of user preferences of device-free interaction with smart appliances and services in the domestic environment. We presented a prototype system for on-surface gesture control to users in a natu-ral environment and surveyed the perceived advantages of a potentially truly ubiquitous input method. Results show a positive attitude of users towards augmenting domestic en-vironments with such a system. By reporting the most influ-encing user characteristics and our experience in designing the system we want to inform developers of future systems that support multiple input devices to better understand the role of device-free input in domestic spaces
