3SPACE FASTRAK
|
|
|
The perfect solution for the position/orientation measuring
requirements of applications
and environments.
(New 2008 housing design.)

|
The 3SPACE FASTRAK accurately computes the position and orientation of a tiny receiver as it moves through space. This device virtually eliminates the problem of latency as it provides dynamic, real time six degree-of-freedom measurement of position (X, Y, and Z Cartesian coordinates) and orientation (azimuth, elevation, and roll), and it is the most accurate electromagnetic tracking system available.
FASTRAK is the perfect solution for interfacing with Virtual Reality environments and controlling simulator projectors or other applications where real time response is critical. It is also ideal for measuring range of motion or limb rotation in biomedical research.It is a fast, accurate, easy to use, and effective method of capturing motion data on any non-conductive object.
The FASTRAK system utilizes a single transmitter and can accept data from up to four receivers. The use of advanced digital signal processing (DSP) technology provides an update rate of 120 Hz (with a single receiver) and a remarkable 4ms latency. The data are then transmitted over a high speed RS-232 interface at up to 115.2K baud. If your application requires using the system in close proximity to a CRT, FASTRAK has special circuitry to allow you to synchronize with it for improved performance.
And because FASTRAK uses patented low-frequency magnetic transducing technology, there's no need to worry about maintaining a clear line-of-sight between receiver and transmitter. Polhemus has eliminated the problem of signal blocking and interference that distorts sonic or laser devices.
In short; the Ideal solution for head tracking, hand tracking, instrument tracking, biomechanical analysis, graphic and cursor control, stereotaxic localization, telerobotics, digitizing and pointing.

Components |
|
|
The 3SPACE FASTRAK system includes a System Electronics Unit (SEU), a power supply, one receiver and one transmitter. You can expand the system's capabilities simply by adding up to three additional receivers. FASTRAK is also available as a board-level product for OEM/VARs.
System Electronics Unit: Contains the hardware and software necessary to generate and sense the magnetic fields, compute position and orientation, and interface with the host computer via an RS-232.
Transmitter: The transmitter is a triad of electromagnetic coils, enclosed in a plastic shell, that emits the magnetic fields. The transmitter is the system's reference frame for receiver measurements.
Receiver: The receiver is a small triad of electromagnetic coils, enclosed in a plastic shell, that detects the magnetic fields emitted by the transmitter. The receiver is a lightweight cube whose position and orientation are precisely measured as it is moved. The receiver is completely passive and highly reliable.
Stylus (Optional): The stylus is a pencil-like device that contains a triad of electromagnetic coils, and is used for digitizing objects, drawing in three-dimensional space, or collecting contours of objects. The stylus is available in 3" or 8" lengths, with either a sharp or round nib.
3BALL (Optional): A triad of electromagnetic coils are housed in a billiard ball for use as a mouse to literally rotate the captured database, act as a light source for shading, or become the eye for perspective views.

Features |
|
|
Real Time: Virtually no latency. Digital Signal Processing (DSP) technology provides 4ms latency updated at 120 Hz. And data is transmitted to the host at up to 100K bytes/sec.
Improved Accuracy and Resolution: Accuracy of 0.03" RMS with a resolution of 0.0002 in./in. makes this the most precise device of its kind.
Range: Standard range is up to 10 feet. Coverage of up to 30 feet is possible with the optional LONG RANGER transmitter.
Multiple Receiver Operation: Permits measurement of up to 4 receivers on a single system and up to 16 receivers at a time, utilizing four multiplexed systems.
Reliable: From the pioneer in 3D position/orientation measuring devices, in business since 1970. Factory calibrated, never needs adjustment.
Multiple Output Formats: Position in Cartesian coordinates (inches or centimeters); orientation in direction cosines, Euler angles or Quaternions

Applications |
|
|
Virtual Reality: From the beginning, Polhemus 3SPACE systems have been the systems of choice for VR head and body tracking applications. Now FASTRAK takes you to the next generation with real time tracking.
Head-Mounted Displays: FASTRAK is the consummate solution for head-mounted displays utilized in military, VR, or simulator applications. FASTRAK virtually eliminates latency (lag).
Biomechanical Analysis: Mount up to 32 receivers on parts of the anatomy and collect real time relative movement data for gait and limb analysis. Perfect for leg, knee, joint, spinal or shoulder rotational measurement.
Graphics: The natural way to manipulate graphics for animation or simulation. The receiver mounted in mouse, stylus, or other hand held device is the ideal way to gain real time control over the placement of cameras, light sources, projectors, or any movable image.
Stereotaxic Localization: The receiver can be mounted on any non-conductive object (such as a robotic prosthesis) to determine its position and orientation.
CAD Database: Develop databases of complex non-metallic objects for CAD, CAE, computer graphic models or simulation.
Dimensional Archiving: Collect actual dimensions of objects such as artifacts, archaeological items, museum sculptures, and other items.
Anatomical Measurements: Collect databases of anatomical features, body volumes, joint relationships and body contours.
