Advances in cognitive neuroscience and brain imaging technologies provide us with the increasing ability to interface directly with activity in the brain. Researchers have begun to use these technologies to build brain-computer interfaces, in which patients with severe motor disabilities can communicate and control devices with thought alone. Although removing the need for motor movements in computer interfaces is challenging and rewarding, we believe that the full potential of brain sensing technologies as an input mechanism lies in the extremely rich information it could provide about the state of the user. Having access to this state information is valuable to human-computer interaction (HCI) researchers and opens up at least three distinct areas of research: controlling computers with thought alone, evaluating systems and interfaces, and building adaptive user interfaces. Although this is not the focus of this workshop, we will consider accepting a small number of position papers proposing methods of using techniques such as transcranial magnetic stimulation (TMS) to send information directly to the brain.
Specifically, this workshop aims to identify and discuss:
* brain-computer interface applications for users with permanent and situational physical disabilities, as well as for able-bodied users. This includes application in domains such as traditional communication and productivity tasks, as well as games and entertainment computing;
* sensing technologies and data processing techniques that apply well to the suite of applications in which HCI researchers are interested;
* techniques for integrating brain activity, whether induced by thought or by performing a task, in the palette of input modalities for (multimodal) human-computer interaction;
* interesting problems that need more work, especially in areas that are unique to HCI applications
We encourage participation from a wide range of disciplines including Neuroscience, Cognitive Psychology, Human-Computer Interaction, Affective Computing, and Artificial Intelligence/Machine Learning. The workshop will be limited to 18 participants. Please submit a 2-4-page position paper outlining your interest in this topic to [log in to unmask] Position papers must be received by 3 October, 2007. Participants will be notified of selection by 28 November 2007. The workshop date is 5 April 2008. CHI workshops are only open to people who have had their position paper accepted by the workshop organizers, and who have registered for the workshop and at least one day of the conference itself.
