Pico Movement Trackers Add Leg Monitoring And Use A Intelligent Calibration Approach

Pico Movement Trackers 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 like Mocopi, Pico Movement Trackers additionally characteristic 12 infrared LEDs every, that are tracked by the headset for 2 functions.

Firstly, they’re used to allow speedy preliminary calibration, the place you merely stand nonetheless and look down. 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 is fed right into a skeletal mannequin to provide believable (however imperfect) estimated leg poses primarily based on the relative rotations & forces of every tracker. It is an attention-grabbing hybrid method we’ve not seen used for leg monitoring earlier than. It ought to present the next 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, presents a claimed 25 hours of battery life, and are charged by way of commonplace USB-C.

Pico Movement Trackers can be found to preorder in China for ¥400 for a pair, which equates to simply beneath $60. Delivery is ready to start on September 2, the identical day as the brand new Pico 4 Extremely headset.

ByteDance says the trackers will probably be supported in PC VR apps resembling VRChat by way of the Pico Join PC VR streaming app, in addition to over 20 standalone VR video games on the Chinese language Pico Retailer.
