Abstract
Recent technological trends in mobile/wearable devices and sensors have been enabling an increasing number of people to collect and store their "lifelog" easily in their daily lives. Beyond exercise behavior change of individual users, our research focus is on the behavior change of teams, based on lifelogging technologies and lifelog sharing. In this paper, we propose and evaluate six different types of lifelog sharing models among team members for their exercise promotion, leveraging the concepts of "competition" and "collaboration." According to our experimental mobile web application for exercise promotion and an extensive user study conducted with a total of 64 participants over a period of three weeks, the model with a "competition" technique resulted in the most effective performance for competitive teams, such as sports teams.
Highlights
T HE development of smartphones, wearable devices and sensor technology have significantly enhanced the ability of humans to capture and record various types of data in their daily lives, Examples of such data include the number of steps [1], sleep information [2], [3], foods consumed [4], [5], and communication amount [6], [7]
Our analysis showed that lifelog data that are closely related to the team’s original performance indicator effectively enhance team behavior change
We focused on the Keio University official baseball club and the computer science laboratory at Keio University as target team for our first experiment
Summary
T HE development of smartphones, wearable devices and sensor technology have significantly enhanced the ability of humans to capture and record various types of data in their daily lives, Examples of such data include the number of steps [1], sleep information [2], [3], foods consumed [4], [5], and communication amount [6], [7]. We study, for the first time, the impact of lifelog sharing on the team behavior change. We propose six different types of lifelog sharing models that promote team behavior change with variation of concepts such as “competition” and “collaboration” (see Section III). This paper makes the following three contributions: 1) proposal of six different types of lifelog sharing models to promote team behavior change, 2) extensive evaluation of the models with a real-world system, and 3) significant analysis results from the evaluation.
