Ascension Launches
Improved Motion Capture Technology
for Best Data Quality
BURLINGTON, VERMONT; March
5, 2004: Ascension
Technology has released
an improved version of the
award-winning MotionStar Wireless®
tracker. With Ascension’s
new Advanced DC Tracking Technology™,
MotionStar Wireless 2
now produces greatly improved
dynamic accuracy. Animators
will find MotionStar outputs
are almost jitter free – minimizing
the need to post process data.
MotionStar Wireless 2 captures
the motions of up to five
individuals in real time without
occlusion or perceptible lag.
No other tracker in the world
captures as many performers’
motions in real time. MotionStar
Wireless 2 lets users jump,
spin, kick and interact with
total freedom of movement
-- free of trailing cables.
It also delivers the most
data per sensor of all motion-capture
trackers. Each sensor measures
a full six degrees-of-freedom
(X, Y, Z, Yaw, Pitch, Roll)
solution. In a 13-sensor system,
this equates to 78 dedicated
data points instantly streaming
onto the performer’s character
for fully articulated and
smooth tracking of each data
point.
For MotionStar Wireless 2,
Ascension developed new backpack
electronics and improved algorithms.
This results in improved vertical
motion accuracy as a performer
moves towards and away from
the system’s magnetic field
generator. It also eliminates
small jumps in data when a
sensor is rotated about its
axis. Upgrade kits are available
for all existing MotionStar
Wireless trackers in the field.
As an added feature to help
animators produce hassle-free
motion capture sessions, MotionStar
Wireless 2 now comes with
free use of Ascension’s Environmental
Analyzer. This tool lets animators
find sources of metal and
noise in their workspace --
the two biggest factors that
previously compromised magnetic
motion capture -- and take
steps to eliminate them.
Richard Hince, head of motion
capture at Artem Studios (West
London, England) recently
evaluated the new MotionStar
Wireless 2 and states, "We
are very excited about the
improvements… As the operators
of one of the largest MotionStar
installations in the world,
we are always pushing the
boundaries of what is achievable.
The data quality increases
with MotionStar Wireless 2
are great and will allow us
to push these boundaries even
further.”
MotionStar Wireless is used
extensively worldwide for
3D animation, biomechanical
analysis, real-time visualization
and interactive gaming. The
tracker’s extensive list of
credentials in the animation
and entertainment field include
The Getaway, Star Wars prequels,
Funky Cops, Starship Troopers
and Radio Shack’s Battery
Man.
Ascension Technology Corporation
develops magnetic, optical
and inertial motion-tracking
solutions for 3D computer-graphics
applications in military targeting
systems, simulation, virtual
reality, biomechanics, animation
and medicine. For more information,
