Designers of handheld controllers used in virtual reality and gaming applications know all too well the frustrations of trying to accurately track head and hand movements with consumer-grade inertial sensors. Most standard inertial sensors have latency issues. In head-mounted displays, this results in inaccurate tracking of head movement – which can leave users feeling nauseous or disoriented. Game controllers have their own challenges, as rapid controller movements can over-saturate gyroscopes, leaving users with skewed visuals and missed targets. And getting the sensors to fuse data together into usable information is often not the simple task it first appears.
PNI’s SpacePoint™ VR and SpacePoint™ CR are 3D motion-tracking systems made expressly for virtual reality game developers. SpacePoint VR is designed with the specific needs of head-mounted displays, while SpacePoint CR addresses the needs of game controllers. The easy-to-integrate SpacePoint systems combine outputs from multiple sensors, applying PNI’s sensor fusion algorithms to get military-grade accuracy.
Key features of the SpacePoint family include:
- High accuracy from the industry’s foremost experts in motion tracking;
- Latency so low it is imperceptible to the human eye;
- Gyro drift compensation that ensures that objects in the virtual world remain where you left them;
- Continuous auto-calibration technology combined with patented Kalman filter algorithms, so the output is extremely accurate in all environments;
- The firmware resides on PNI’s SENtral coprocessor, which offloads sensor management and fusion work from the main processor;
- SpacePoint handles all the motion sensor calculations, so there are no unpleasant surprises or wasted engineering time.
