CHI-WS: Evaluating Affective Interfaces­--Innovative Approaches

Call for Participation for a workshop held at CHI 2005 Evaluating Affective Interfaces­--Innovative Approaches Katherine Isbister, Rensselaer Polytechnic Institute, U.S.A., isbisk@rpi.edu Kristina Höök, Swedish Institute of Computer Science, Sweden, kia@sics.se There is strengthening interest within the CHI community in designing affective engagement with interfaces. Affect is an important part of user engagement with games, interactive narrative, synthetic characters and robots, wearables, voice interfaces, and many other interactive systems. Systems designed to promote community or to enhance safety, two key themes at this year’s conference, also benefit from consideration of users’ emotional states. Core CHI practitioners have promoted the value of thoughtfully crafting emotional qualities of interfaces (e.g. Don Norman’s 2003 CHI keynote; October 2004 ‘Funology’ issue of Interactions). Research has advanced our abilities to detect affect in users and incorporate this into system response (e.g. Picard, 2000). But how do we determine whether someone has been affected emotionally in the way we’d like, by interacting with a system? How do we test affective responses early in the design cycle­? What kinds of prototyping are appropriate? Where do traditional HCI methods fall short? What new techniques and advances can be used to improve the design and evaluation cycle for creating affective interfaces? This one-day workshop brings together researchers and industry practitioners in the area of affective interface design and evaluation, in order to: 1. Bring together examples of affective interface evaluation strategies already in use. 2. Put together a list of current best practices, and collect a body of references from past efforts to evaluate affective reactions to designed systems (both successes and failures), to help us all leverage what is already known. 3. Identify key challenges and issues for future work. We invite submissions of two varieties: 1. A brief, 2-4 page paper describing either - affective evaluation techniques you use which are effective. - explorations of new tactics for affective evaluation and design. Examples of affective evaluation techniques might include (but are not limited to): biometrics, questionnaire design, video analysis, focus groups, participatory design strategies. The focus should be upon how this technique allows you to gauge users’ affective reactions to your system, toward more effective design. 2.A brief demonstration of an affective system that requires evaluation. If you are proposing a demonstration, submit a 2-4 page paper describing the system, including images, and discussing key challenges in evaluation. (Please only propose a demonstration that you can bring along on your own laptop for display). Papers and demonstrations will be selected for the workshop by the program committee based upon their relevance to the core topic and outcome goals of the workshop. Submit papers to Katherine Isbister (isbisk@rpi.edu) by January 3, 2005. More information about the workshop can also be found at http://www.rpi.edu/~isbisk/chi2005/CHIworkshop.html.
