Pico Movement Trackers are an adjunct you put on so as to add leg monitoring to Pico 4 Extremely, Pico 4, and Pico Neo 3.
Like Sony’s Mocopi, every Pico Movement Tracker options an inertial measurement unit (IMU) containing a tiny accelerometer and gyroscope. However not like different IMU trackers, Pico Movement Trackers additionally function 12 infrared LEDs every, that are tracked by the headset for 2 functions.
The primary is speedy preliminary calibration. You merely stand nonetheless and look down, and the bottom place of your legs is measured. From then on, they’re used to supply true 6DoF positional monitoring at any time when a tracker is inside view of one of many headset’s monitoring cameras.
After they’re not in view of a digital camera, the IMU knowledge is fed right into a skeletal mannequin to supply believable (however imperfect) estimated leg poses. This hybrid mannequin is an fascinating method we’ve not seen used for leg monitoring earlier than. It ought to present a better high quality output than pure IMU trackers at a considerably decrease price than Vive Trackers.
ByteDance claims an “common place error of 5 cm, a mean angle error of as little as 6°, and an accuracy of not lower than 98% for stepping motion judgment and restoration” with a latency of lower than 20 milliseconds.
Every tracker weighs simply 27 grams, affords a claimed 25 hours of energetic use, and is charged by way of commonplace USB-C.
