Moraveji, Neema, Akasaka, Ryo, Pea, Roy and Fogg, B. J. (2011): The role of commitment devices and self-shaping in persuasive technology. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1591-1596.

We examine the role of self-shaping and commitment devices in persuasive systems. Self-shaping refers to the practice of taking purposeful action in modifying one's environment in order to shape or influence one's own future behavior. We present results from a survey of 23 users that assessed the role self-shaping plays in their use of persuasive technologies. A second survey elicited 65 self-shaping designs from 41 expert users, finding the Fogg Behavior Model describes how the designs were indeed persuasive. We then reviewed 85 tools based on this model to show the two dimensions that can be used to organize persuasive devices: (1) salience of a tool's self-shaping features and (2) their intended flexibility. The resulting four categories of tools are useful for researchers and designers of persuasive systems.

Moraveji, Neema, Olson, Ben, Nguyen, Truc, Saadat, Mahmoud, Khalighi, Yaser, Pea, Roy and Heer, Jeffrey (2011): Peripheral paced respiration: influencing user physiology during information work. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 423-428.

We present the design and evaluation of a technique for influencing user respiration by integrating respiration-pacing methods into the desktop operating system in a peripheral manner. Peripheral paced respiration differs from prior techniques in that it does not require the user's full attention. We conducted a within-subjects study to evaluate the efficacy of peripheral paced respiration, as compared to no feedback, in an ecologically valid environment. Participant respiration decreased significantly in the pacing condition. Upon further analysis, we attribute this difference to a significant decrease in breath rate while the intermittent pacing feedback is active, rather than a persistent change in respiratory pattern. The results have implications for researchers in physiological computing, biofeedback designers, and human-computer interaction researchers concerned with user stress and affect.
