Perry, Daniel and Aragon, Cecilia (2012): Measuring distributed affect in collaborative games. In: Companion Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 195-198. http://dx.doi.org/10.1145/2141512.2141576

The ability to engage children in science, technology, engineering, and math (STEM) fields early in their scholastic years is critical to ensure the success of the next generation of scientists and engineers. Given that 97% of American teens play video games, there is a tremendous opportunity to engage students in STEM concepts within the framework of a multi-player game. Research has shown that eliciting emotional and affective responses in players can actively increase engagement, learning, and creativity, yet surprisingly little attention has been paid to the role of emotion within a collaborative multi-player gaming environment. We propose the design and development of an automatic game master that responds to the emotional states of players based on their in-game dialogue and actions. This research offers insights into affective interfaces that can improve the collaborative engagement of students and has implications for other collaborative learning environments.

Perry, Daniel, Aragon, Cecilia, Meier, Alan and Pritoni, Marco (2011): Developing standards for affordances on embedded devices. In: Proceedings of the 2011 iConference 2011. pp. 746-748. http://dx.doi.org/10.1145/1940761.1940894

Embedded devices are ubiquitous in our environment, including computing systems as widely diverse as digital watches, automobile dashboards, factory controllers, thermostats and other appliances. Traditionally, little attention has been paid to the user interface in such low-cost, dedicated-function devices. However, new technologies such as touchscreens are changing the landscape of embedded user interface design. Additionally, recent research has demonstrated that usability can have a significant effect on embedded device efficiency. Research on programmable thermostats in particular points to the need for proficient and consistent user interface design in order to realize energy savings nationwide. We discuss preliminary results from an in-depth usability study conducted on five programmable thermostat interfaces (three touchscreen, one web, and one-button based) with 31 participants. Our research suggests that users lacked a consistent mental model of how to interact with buttons, text, icons, and other features of the device. We hypothesize that discrepancies between perceived and actual affordances on the device had a measurable impact on users' ability to successfully accomplish key tasks on the thermostats.
