HEARTRATE MONITOR FOR AR WEARABLES

A heartrate monitor distributed adjusted reality system for producing rendered environments includes an eyewear device and a neckband formed from a first arm, second arm, and computation compartment. Optical, electrical and visual sensors are distributed across the neckband and eyewear device at points of contact with a user's tissue. Machine learning modules combine optical, electrical and visual measurements produced by the optical, electrical and visual sensors to determine a user's heartrate and/or other vitals. The neckband and eyewear device may be capable of adapting an adjusted reality environment in response to a determine user heartrate or other vitals.
