Abstract
This
project, developing a highly integrated and modular system for
affective sensing research, aims at designing, developing, verifying,
and disseminating an instrumentation setup that can be used to sense,
record, and identify physiological changes that signal affective shifts
relevant to human-computer interaction (HCI). A large number of
biological signal sensors will be integrated for the purpose of
developing HCI with the ability to respond to the state of the user's
autonomic nervous system (including user emotion and affect, and states
related to exercise and health). Affective computing implies that a
computer system should be able to assess the emotional state of the
subject, i.e., perform affective sensing based on real-time monitoring of
the physiological expression of the user's affective state.
Non-invasive/unobtrusive measurements in this monitoring process
ultimately yield enhancements in HCI. Physiological manifestations of
sympathetic activation associated with affective shifts in a highly
integrated sensory platform may reveal inconspicuous but relevant
features that could be overlooked when the signals are observed in
isolation. The work involves five sets of experiments: -DSP for
affective sensing, -Real-time measurement of eye gaze tracking,
-Analysis of the relationship between exercise and blood volume, -EEG
as a way to assess the quality of HCI, and -Autonomic nervous system
monitoring as a way to assess HCI. Broader Impact: This affective
sensing system can be used as an evaluation platform toward the design
of the next generation of human computer interfaces that would improve
access and functional capabilities of persons with disabilities. The
development of the instrument will impact the training and motivation
of future professionals and researchers. This work contributes in the
creation of new initiatives to engage students in an institution
serving a large number of minority students; thus strengthening the
student pipeline towards graduate degrees.
