InterSense Head-tracking Technology added to AuSIM Audio
Simulation Systems for Research and Development

The Inclusion of Trackers Creates Fully Turnkey Simulation

Mountain View, California – November 27, 2002

AuSIM announced today the enhancement of its family of GoldSeries^tm audio simulation systems with the addition of head-orientation trackers from InterSense.  AuSIM selected InterSense as its standard provider of head-orientation trackers based on the quality and innovation of the products and their applicability to a wide variety of customer requirements.

AuSIM’s audio servers synthesize a sound space in a completely natural and realistic way, using physical modeling and empirical data.  Trackers are instruments that sense the motion and orientation of the user’s head.  Motion tracking facilitates the interaction between the listener and the simulated audio environment by controlling the relative position of sound in the listener’s headphones.

"Head-motion is a principal method for listeners to naturally discriminate sound.  InterSense's products provide our systems with stable, sourceless, and real-time orientation data," according to William L. Chapin, President of AuSIM.  "This data is critical for our AuSIM3D™ engine, which is optimized to react to listener movement.  The inclusion of the tracker makes our GoldSeries servers truly 'turn-key' solutions."

InterSense’s InertiaCube2 tracker, which provides three degrees of freedom tracking (3-DOF) will become part of AuSIM's GoldMiner^tm and RollingNugget^tm development systems.  InterSense's InterTrax2 will round out the reCREate^tm system, a direct replacement for older Crystal River Engineering Acoustetron II systems.

"AuSIM has integrated InterSense’s standard tracker libraries into their 3D Audio product offering, providing native support for our full tracking product line," states Dean Wormell, Manager of Strategic Partnerships for InterSense.  "The joint product offering from AuSIM is initially bundled with our 3-DOF products, but can also configured to work with our 6-DOF product line for additional applications in simulation, training and mobile field operations."

Demonstrations of AuSIM’s portable RollingNugget system will be shown in the InterSense booth (# 984) at the Interservice/Industry Training, Simulation and Education Conference in the Orlando County Convention Center, Orlando, Florida, from December 2-5, 2002.
