If HMDs are the external symbol of virtual reality applications,
tracking systems are the real engine between all successful
interactive environments.
Motion tracking measures and reports an object's position
and orientation as it changes in time. When you move your
computer mouse and your cursor mirrors that movement,
you are tracking motion in a very simple way. Precision
motion tracking technology allows you to track objects
in 3-dimensional space - X, Y, Z, yaw, pitch, and roll
- or 6 degrees-of-freedom (6DOF).
Motion tracking facilitates the interaction between people
and computers. Historically, the lack of smooth and rapid
tracking of the user's motion has blocked commercial acceptance
of immersive 3D computer graphics. To be successful, the
perspective of the virtual image seen by the computer
must be an accurate representation of what we see in the
real world. As the user's head or camera moves, turns,
or tilts, the computer-generated environment must change
accordingly with no noticeable lag, jitter or distortion. |

| InterSense, a leader in precision motion tracking,
utilizes patented, inertial-based technology to
deliver fast, accurate, driftless motion tracking
solutions free of the lag and jitter common to traditional
technologies. InterSense's software and hardware
technologies, originally developed and patented
at MIT, have set a new standard in motion tracking
by significantly improving upon the precision, performance
and price of magnetic, optical and mechanical trackers. |

InertiaCube2 |
 |
|
The InertiaCube2 is the World's smallest
inertial orientation reference system. Connecting directly
to the PC's RS-232 serial connector, the tracker's 180
Hz update rate eliminates tracker induced lag. Controllable
filters, adjustable rotational sensitivity and settable
motion prediction provides fine-tuning of the InertiaCube2
for your specific application.
The InertiaCube2 comes with a software developers kit
(SDK) which includes IServer control & connectivity
software, dynamic link and shared object libraries (.dll
and .so), making it ideal for your Windows, Linux and
IRIX applications.

IS-300 Pro |
 |
|
The IS-300 Pro supports the industry's
fastest update rate (up to 500Hz) and provides the world's
lowest latency tracking device. It is completely sourceless,
meaning no setup, no line-of-sight constraints and virtually
unlimited operating range.
The IS-300 Pro predicts motion up to 50 ms in the future,
compensating for graphics rendering delays and eliminating
simulator lag. InterSense is the only company to employ
the proven benefits of inertial angular rate and acceleration
sensors to provide accurate feed-forward motion prediction.

IS-900 Wireless Modules |
 |
|
Designed to augment the current IS-900
systems, the new Wireless Modules provide freedom from
wires connected to the IS-900 Processor. The Wireless
Receiver and Transmitter pairs are plug compatible with
IS-900 VET, VWT and SimTracker systems.
InterSense designed its' wireless technology with field
proven 2.4 GHz spread spectrum technology. The current
MiniTrax devices plug into a small, belt clip module containing
a rechargeable battery and transceiver circuitry. As with
the original MiniTrax devices, the new wireless implementation
is ergonomically designed for use with data gloves and
stereo glasses.
IS-900 Wireless Modules Features:
Advanced Radio Technology - Spread spectrum 2.4
GHz frequency hopping communications for interference
free operation.
Smart Battery Power - The rechargeable lithium
ion battery provides 6 to 8 hours of continuous operation.
Auto sleep circuitry detects periods of non-use to conserve
battery power. Auto connect circuitry reestablishes
tracking communication to IS-900 Processor without system
reset.
Lightweight Compact Packaging - Belt clip Wireless
Transmitter Module is 5.9 cm x 9.5 cm x 2.5 cm and weighs
126 grams. Wireless Receiver Module is 6.1 cm x 9.4
cm x 2.5 cm and plugs into IS-900 Processor.

MiniTrax Devices |
 |
|
Designed to augment the current IS-900 systems, the
new MiniTrax devices provide the same performance as
the Wand and Stylus Trackers with reduced weight &
size. InterSense has employed new advanced ultrasonic
& inertial technology to reduce the size & weight
by 75% without sacrificing the IS-900 performance. The
devices are ergonomically designed for use with data
gloves and stereo glasses.
IS-900 MiniTrax Features:
Reduced Size - The worlds most precise, real-time
6DOF position and orientation tracking system, now with
75% smaller, lightweight sensors.
Advanced Inertial Technology - Advanced MEMS components
are integrated in the inertial core of the MiniTrax
stations to provide lower sensor noise and overall tracking
performance improvements.
Miniature Ultrasonic Microphones - The new 2
mm diameter microphones used in the MiniTrax device
provide a 180¡Æ reception cone angle for the acoustic
pulses from the IS-900's ultrasonic transmitters (SoniStrips).
This improves overall tracking performance and reduces
the number of microphones needed on the tracked device.
Serial Protocol Communication - The new devices
communicate to the IS-900 processor via an in-line converter
that changes the InterSense station protocol communication
interface to a serial data stream. The serial protocol
allows for greater cable lengths and a simplified design
approach for future wireless implementation.
