CHI 2011 WORKSHOP - BRAIN AND BODY INTERFACES: DESIGNING FOR
MEANINGFUL INTERACTION

http://brainandbody.physiologicalcomputing.net

CALL FOR PARTICIPATION

The brain and body provide a wealth of information about the
physiological, cognitive and emotional state of the user. There is an
increasing opportunity to use physiological data as a form of input
control for computerised systems. As entry level sensors become more
cheaper and widespread, physiological interfaces are liable to become
more pervasive in our society (e.g., through mobile phones and similar
devices). While these signals offer new and exciting mechanisms for
the control of interactive systems, the issue of whether these
physiological interfaces are appropriate for application and offer the
user a meaningful level interaction has been relatively unexplored.

The goal of this one-day workshop is to bring together researchers
working on brain and body interactive systems in order to (1) provide
a platform for understanding physiological interaction in different
research strands, (2) establish a forum for the discussion of
technologies, techniques and measures, and (3) build and extend the
physiological computing community.

WORKSHOP SUBMISSIONS

We are inviting technical contributions on the following three topics:

1. An Application Approach to Sensor Design

The design of a sensor at the hardware and software level defines the
type of application for which the device is suitable. In medical and
psychophysiological research, high-resolution data capture under
laboratory conditions is standard. However not every type of
physiological computer requires high-fidelity equipment and many of
these systems must work in the field. Perhaps the physiological
variable that drives the application must be captured with a degree of
sensitivity and robustness. The application domain defines the
requirements of the sensor and the type of hardware/software support
required.

In submitting under this topic, we ask researchers to consider how the
type of application influences the specification of measures and the
required specification for sensor design. For example, a heart rate
sensor combined with an accelerometer allows physical effort to be
removed from changes in heart rate, allowing cognitive and emotional
effects to be processed.

2. Meaningful Interactions with Physiology

A physiological computing system can define the relationship between
the changes in a physiological signal and a system command in any
number of ways. However, certain relations between the physical and
virtual will be more intuitive if they can be made meaningful from the
perspective of the user (i.e., a natural interaction). For example,
increases and decreases in psychophysiological activation should lead
to changes that are both appropriate and intuitive at the interface.

In submitting under this topic, we ask researchers to consider what
defines a meaningful physiological interaction and what types of
meaningful interaction may exist across different categories of
physiological computing system (e.g. BCI, telemedicine, affective
computing). We also welcome contributions with regard to methods that
evaluate meaningful interaction within this context.

3. Ethics and Privacy

Physiological data of users are a highly personalised and private
source of information. The storage and/or manipulation of these data
can pose certain ethical concerns. For example, the uploading of
physiological statistics to an online forum outside a medical context
may lead to unsubstantiated self-diagnosis.

In submitting under this topic, we ask researchers to consider the
ethics and privacy issues involved in the storage and/or manipulation
of a users physiology (e.g., in biocybernetic adaptive systems) and to
what extent should we allow the userís state to be manipulated?

SUBMISSION DETAILS

Authors are asked to submit a 4 page position paper in the CHI
extended abstracts format to [log in to unmask] by 14
Jan, 2011. Papers may describe ongoing work, recent results, or
opinions and approaches related to the workshop topic.

A short biography of the author(s) attending the workshop needs to be
included (100-150 words). Papers will be peer-reviewed and the
organizing committee will select up to 20 participants according to
relevance, quality of results, research diversity, and likelihood for
stimulating and contributing to the discussion. If accepted, at least
one author must register for the workshop and for one or more days of
the conference. Papers will also be compiled on the workshop website.

SCHEDULE

    * Submission deadline: January 14th, 2011
    * Notification of acceptance: February 11, 2011
    * Workshop: May 7 or 8th, 2011 (to be confirmed)

ORGANISING COMMITTEE

    * Stephen H. Fairclough, Liverpool John Moores University, UK
    * Kiel Gilleade, Liverpool John Moores University, UK
    * Lennart E. Nacke, University of Saskatchewan, Canada
