Pervasive Informatics and Persistent Actimetric Information in Health Smart Homes
نویسندگان
چکیده
This paper discuss the ability to obtain a reliable pervasive information at home from a network of localizing sensors allowing to follow the different locations at which a dependent (elderly or handicapped) person can be detected. The data recorded can be treated as the sequence of color coding numbers of balls (symbolizing activity-stations) taken in a Polya’s urn, in which the persistence of the presence in an activitystation is taken into account by adding a number of balls of the same color as the ball just drawn. We discuss the pertinency of such a procedure to early detect sudden or chronic changes in the parameters values of the random process made of the succession of ball numbers and we use it to trigger alarms.

Modeling patterns of activities using activity curves
Pervasive computing offers an unprecedented opportunity to unobtrusively monitor behavior and use the large amount of collected data to perform analysis of activity-based behavioral patterns. In this paper, we introduce the notion of an activity curve, which represents an abstraction of an individual's normal daily routine based on automatically-recognized activities. We propose methods to dete...
متن کاملSmart meters: A users' view
Smart meters are assumed to contribute to energy conservation by providing updated consumption data to energy utilities, but, given their pervasive presence in consumers’ homes, they could also provide timely feedback to energy consumers/users. A precondition, however, is that smart meters are really usable to lay consumers. In the present study 40 participants were videorecorded while performi...
