Current Projects

	Using Bend as Input in Flexible E-Ink Displays Flexible displays potentially allow for interaction styles that resemble those used in paper documents. Bending the display, e.g., to page forward, shows particular promise as an interaction technique. We present an evaluation of the effectiveness of various types of bends in executing a set of tasks with a flexible display. CHI 2011: paper, interactivity 2010 - 2011
	Perspective Based Remote Multitouch We present a set of remote pointing techniques that allows bimanual and multi-finger remote manipulation of graphical objects on large displays. CHI 2011: work-in-progress 2010 - 2011
	Active Progress Bars When a progress bar pops up, can a better design help you do something relaxing or productive while waiting? We propose to augment progress bars with user controlled functionalities facilitating the switch to temporary activities. CHI 2011: work-in-progress 2010 - 2011
	Organic User Interface Workshop Advances in display, sensor and actuator technology are changing the field of TEI. While modern interfaces were designed for traditional planar and static display devices, next-generation UI allow digital objects to change their shape and embed displays anywhere. These developments require us to re-examine and reevaluate basic design principles and interaction styles currently used. This workshop on Organic User Interfaces brings together experts to discuss, brainstorm and prototype next generation of user interfaces.

Past Projects

	Adaptive Interface using fNIRS We use functional Near Infrared Spectroscopy (fNIRS), a new non-invasible brain imagery device, as an additional input to an interface. Brain-computer interfaces could be used to evaluate new interfaces, or create interfaces that adapt to the user's mental workload, or emotions, for example.

	Brain, Body and Bytes: Psychophysiological User Interaction The human brain and body are prolific signal generators. Recent technologies and computing techniques allow us to measure, process and interpret these signals. We can now infer such things as cognitive and emotional states, to create adaptive systems and gain an understanding of user experience. In this workshop, we aim to bring together researchers from fields such as HCI, interaction design, cognitive science, psychophysiology, game research, and BCI. A CHI 2010 Workshop.

	Reality Based Interfaces We propose the notion of Reality-Based Interaction (RBI) as a unifying concept that ties together a large subset of emerging human-computer interaction styles. Presented at CHI 2008. [website] Human Computer Interaction 2006 - 2008
	SmartBlocks Tangible Blocks that help children learn Volume and Surface Area Presented at TEI 2007. [website] Human Computer Interaction, Tangible User Interfaces 2006
	Leave-one-out Scoring A new method for collecting information about motifs from any motif discovery program Presented at CIBCB 2006. Computational Biology 2006
	Lessons for decompiling an embodied cognitive model We decompiled different Soar models into Herbal. We propose a "decompilation" process as a standard means for evaluating high level behavior modeling languages with respect to their low level equivalents. Presented at Cognitio 2006. Cognitive Science 2006
