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 in contrast to different IMU trackers, Pico Movement Trackers additionally function 12 infrared LEDs every, that are tracked by the headset for 2 functions.
They’re firstly used to allow fast 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 offer true 6DoF positional monitoring at any time when a tracker is inside view of one of many headset’s monitoring cameras.
Once 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 attention-grabbing strategy we have 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 value than Vive Trackers.
ByteDance claims an “common place error of 5 cm, a median 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, presents a claimed 25 hours of energetic use, and is charged through customary USB-C.
