Call for Participation for CHI2006 Workshop, on April 22rd

HCI and the Face

Important Update: The CHI workshops will take place at the Hyatt Regency Hotel and NOT at the Palais des Congrès where the rest of the conference is located.

The human face plays an important role in many aspects of verbal and non-verbal communication. As such, the face is a rich source of information relevant to human-computer interaction. The fields of eye gaze tracking and face recognition have both reached sufficient maturity that several companies now offer commercial products based on these technologies. By contrast, other aspects of facial information processing, including expression and gesture recognition have yet to reach a comparable stage of development.

This workshop will consist of a general assessment of the state of the art of facial information processing in HCI. By examining a broad range of topics in HCI related to this theme we will attempt to understand why certain areas of face-based HCI, such as facial expression processing and robotic facial display, have lagged others, such as gaze tracking, and identity recognition. The goal is to collectively arrive at a set of research strategies to bring the more slowly developing areas up to speed.

An extended list of possible topics will be made available at the workshop’s web site. Briefly:


The workshop will consist of a day long highly interactive format that will encourage group dialogue and knowledge transfer/sharing.

Submission Details

Submissions should consist of 2 - 4 page position statements in ACM format. Statements should be submitted as PDF files not exceeding 5 MB in size, and should be sent by e-mail to
