Computers Understand Hand-Waving Descriptions
New Scientist (07/20/11) Nic Fleming
A new gesture-based interface developed by the Hasso Plattner Institute's
Christian Holz and Microsoft Research's Andy Wilson does not require users
to memorize a specific set of movements. With Data Miming, users trace the
key components of objects such as a chair or table with their hands and
maintain the proportions throughout the mime. "Starting from the observation
that humans can effortlessly understand which objects are being described
when hand motions are used, we asked why computers can't do the same thing,"
Holz says. The system uses a Microsoft Kinect motion-capture camera to
create a three-dimensional representation of hand movements. Users activate
voxels, or pixels in three dimensions, when they pass their hands through
space. Data Miming understands when enclosed space should be included in
representations, which it compares with a database of objects in the form of
voxels and selects the closest match. The system correctly recognized 75
percent of mimes in tests, and the intended object was among the top three
matches in its database 98 percent of the time.
