Lew, Letitia, Nguyen, Truc, Messing, Solomon and Westwood, Sean (2011): Of course I wouldn't do that in real life: advancing the arguments for increasing realism in HCI experiments. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 419-428. http://dx.doi.org/10.1145/1979742.1979621

We offer a nuanced examination of the way that realism can impact internal and external validity in HCI experiments. We show that if an HCI experiment lacks realism across any of four dimensions -- appearance, content, task and setting -- the lack of realism can confound the study by interacting with the treatment and weakening internal or external validity. We argue furthermore, that realism can be increased while still maintaining control: analogue experiments allow researchers to conduct experiments in more ecologically valid environments and online experiments bridge the gap between the cleanroom and field. While increasing the level of realism in an experiment can introduce noise, technological developments have made it easier to collect rich analytics on behavior and usage.

Dow, Steven, Kulkarni, Anand, Bunge, Brie, Nguyen, Truc, Klemmer, Scott and Hartmann, Bjorn (2011): Shepherding the crowd: managing and providing feedback to crowd workers. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 1669-1674. http://dx.doi.org/10.1145/1979742.1979826

Micro-task platforms provide a marketplace for hiring people to do short-term work for small payments. Requesters often struggle to obtain high-quality results, especially on content-creation tasks, because work cannot be easily verified and workers can move to other tasks without consequence. Such platforms provide little opportunity for workers to reflect and improve their task performance. Timely and task-specific feedback can help crowd workers learn, persist, and produce better results. We analyze the design space for crowd feedback and introduce Shepherd, a prototype system for visualizing crowd work, providing feedback, and promoting workers into shepherding roles. This paper describes our current progress and our plans for system development and evaluation.

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. http://dx.doi.org/10.1145/2047196.2047250

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.
