TL;DR: Experimental results are presented showing that 802.11 and GSM beacons are sufficiently pervasive in the greater Seattle area to achieve 20-30 meter median accuracy with nearly 100% coverage measured by availability in people's daily lives.

TL;DR: This work has developed a system, UbiFit Garden, which uses on-body sensing and activity inference and a personal, mobile display to encourage physical activity to address the growing rate of sedentary lifestyles.

TL;DR: Houston, a prototype mobile phone application for encouraging activity by sharing step count with friends is described and four design requirements for technologies that encourage physical activity are presented, derived from a three-week long in situ pilot study that was conducted with women who wanted to increase their physical activity.

TL;DR: In this article, a wearable activity recognition system is proposed to recognize human activities from body-worn sensors, which can further open the door to a world of healthcare applications, such as fitness monitoring, eldercare support, long-term preventive and chronic care, and cognitive assistance.

TL;DR: A three-phased formative study of whether and what users are willing to disclose about their location to social relations shows that the most important factors were who was requesting, why the requesters wanted the participant's location, and what level of detail would be most useful to the requester.
