Automated health behavior interventions that involve discretionary use by patients or consumers over extended periods of time are becoming more common and it is generally assumed that adherence to the recommended schedule is related to the impact of the system on users. Yet reasons for use or non-use of such systems have not been carefully explored. An(More)
The burgeoning of consumer health informatics and virtual health care can help people improve their health. However, little is known about individuals' reactions to such systems. We conducted an evaluation of the telephone-linked care (TLC) system, a computer-based telecommunications system, that functions as an at home monitor, educator, and counselor for(More)
Our multi-disciplinary team is developing mobile computing software that uses "just-in-time" presentation of information to motivate behavior change. Using a participatory design process, preliminary interviews have helped us to establish 10 design goals. We have employed some to create a prototype of a tool that encourages better dietary decision making(More)
Automated dialogue systems delivered over the telephone offer a promising approach to delivering health-related interventions to populations of individuals at low-cost. Over the past two decades, an automated telephone system called Telephone-Linked Care or TLC has been successfully designed and evaluated by the authors and their colleagues. This work has(More)

We conducted a qualitative evaluation of two systems that promoted physical activity and healthy dietary behavior respectively. Two themes that emerged dealt with favorable responses of the users to the machine's intrinsic qualities of being insentient(More)

This study reports reactions that patient users expressed in ethnographic(More)
