2 Introduction
Thank you for purchasing PNI Sensor Corporation‟s SpacePoint Scout motion-tracking module,
pn 13317. We‟re certain you‟ll be impressed with its performance.
The SpacePoint Scout outputs precise data regarding the module‟s orientation. This can be used
for a variety of motion-tracking applications, most notably for motion-based controllers for TV
and set-top box navigation, and for video gaming. The impressive performance of the
SpacePoint Scout allows a manufacturer to competitively differentiate their products by easily
incorporating intuitive, accurate, and low-latency motion control into their systems.

Today‟s controllers are becoming more intuitive with the addition of gyros and accelerometers,
but these sensors alone result in drift and inaccurate pointing. As shown in Figure 2-2, the
SpacePoint Scout incorporates PNI‟s Geomagnetic Sensor Suite with a 3-axis gyroscope and 3-
axis accelerometer, resulting in accurate motion tracking with no gyro drift. The system outputs
are internally processed using PNI‟s SpacePoint algorithm to provide calculated orientation data
in the form of quaternions, and horizontal and vertical cursor positions.
