3D Data Acquisition Platform for Human Activity
Understanding
Implementing motion capture devices, 3D vision sensors, and EMG sensors to cross validate multimodality
data acquisition and address fundamental research problems involving the representation
and invariant description of 3D data, human motion modeling and applications of human activity
analysis, and computational optimization of large-scale 3D data.

eliable online recognition and prediction
of human actions and activities
in temporal sequences has many potential
applications in a wide range of
Army-relevant fields, ranging from video
surveillance, warfighter assistance,
human computer interface, intelligent
humanoid robots, and unmanned and
autonomous vehicles, to diagnosis, assessment
and treatment of musculoskeletal
disorders, etc. A computational approach
for action prediction can extend
these findings to machines and also promote
further research in human prediction
and intention sensing.
Apparently, a practical prediction system
must output a rapid response for
partial observations. This brings up a
new challenge to the computational
models and motivates machine learning
researchers to make more progress.
Moreover, action prediction will need
to model temporal structures and may
raise an important advance for action
recognition. The underlying basic goal
is to enhance the DoD's capabilities of
visual intelligence for leveraging automatic
human activity understanding
using 3D data acquisition platforms.
Using 2D visual information captured
by single or multiple cameras for
human activity recognition has been
extensively studied and applied to realworld
systems in the past decade. However,
a remaining open problem is how
to generalize existing models and
frameworks to robust and viewpoint-independent
recognition and even prediction
of diverse human actions and activInnovative
