Ubiquitous computing technologies create new opportunities for pre- ventive healthcare researchers to deploy behavior modification strategies out- side of clinical settings. In this paper, we describe how strategies for motivating behavior change might be embedded within usage patterns of a typical elec- tronic device. This interaction model differs substantially from prior approaches to behavioral modification such as CD-ROMs: sensor-enabled technology can drive interventions that are timelier, tailored, subtle, and even fun. To explore these ideas, we developed a prototype system named ViTo. On one level, ViTo functions as a universal remote control for a home entertainment system. The interface of this device, however, is designed in such a way that it may unobtru- sively promote a reduction in the user's television viewing while encouraging an increase in the frequency and quantity of non-sedentary activities. The de- sign of ViTo demonstrates how a variety of behavioral science strategies for motivating behavior change can be carefully woven into the operation of a common consumer electronic device. Results of an exploratory evaluation of a single participant using the system in an instrumented home facility are pre- sented.

    • "Many home monitoring and interaction applications rely heavily on location information and would benefit from cheaper and more reliable location predictions. Examples of such applications include monitoring of activity patterns [2], provision of activities to keep the elder proactive [3], detection of safety critical conditions such as falls [4] and medication adherence promotion [5]. A significant proportion of home monitoring research uses non-identifiable sensors such as Passive Infra-Red (PIR) sensors, pressure mats and reed switches on doors to detect the location of the elder.

    ABSTRACT: The ability to automatically detect the location of an elder within their own home is a significant enabler of remote elder supervision and interaction applications. This location information is typically generated via a myriad of sensors throughout the home environment. Even with high sensor redundancy, there are still situations where traditional elder monitoring systems are unable to resolve the location of the elder. This work develops a minimal infrastructure radio-frequency localisation system for long-term elder location tracking. An RFID room-labelling technique is employed and with it, the localisation system developed in this work is shown to exhibit superior performance to more traditional localisation systems in realistic long-term deployments.

    • "This omnipresent monitoring facility is envisaged to allow elders to live in their own home for longer before requiring a more specialised care environment. A wide variety of services can be provided to an elder by their smart home, including; monitoring of activity patterns [17] [20], provision of activities to keep the elder proactive [15], detection of safety critical conditions like falls [5] and medication adherence promotion [13]. As with most smart home functionalities, these technologies require some technique to detect the current context or activities of the user. "

    ABSTRACT: With the obvious eldercare capabilities of smart environments it is a question of "when", rather than "if", these technologies will be routinely integrated into the design of future houses. In the meantime, health monitoring applications must be integrated into already complete home environments. However, there is significant effort involved in installing the hardware necessary to monitor the movements of an elder throughout an environment. Our work seeks to address the high infrastructure requirements of traditional location-based smart home systems by developing an extremely low infrastructure localisation technique. A study of the most efficient method of obtaining calibration data for an environment is conducted and different mobile devices are compared for localisation accuracy and cost trade-off. It is believed that these developments will contribute towards more efficiently deployed location-based smart home systems.

For example, Nawyn, Intille, and Larson showed how a persuasive remote control could lead to reduced TV watching levels by steering the user towards more dynamic activities [8]. In the health domain, there are several examples of how persuasive technology can be used to encourage healthy behavior. "

    ABSTRACT: The use of context-aware technology in the home enables new ways to stimulate elderly in increasing their exercise levels, and consequently prevent age-related health issues amongst an increasing elderly population. This paper describes the design of a persuasive virtual coach that encourages seniors to walk more. In order to incorporate the user values and needs in the design concept, a user panel of elderly people was actively involved in the design process. A range of persuasive principles and interaction metaphors were evaluated with the user panel, resulting in a design concept that was approved and appreciated by the user panel. The design concept combines a pedometer with wireless connectivity with a touch-screen photo frame. As a first step towards a longer evaluation, an experimental prototype was tested in the field with two participants for 11 days each. Whereas the participants of the exploratory intervention did appreciate the virtual coach and they did feel more motivated to exercise, the quantitative figures did not yet show an increase in physical activity in time; a possible explanation could be the limited activity-sensing capabilities of the prototype in combination with the changing weather conditions in the course of the user study. Furthermore, the participants would like to see a system with a better awareness of the context of use, such that the system can better select the right timing for motivational cues. These findings will be used to improve the design concept and perform a longitudinal user study in the field.
