Abstract
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.
Claims21
A heartrate monitor device comprising:
- a neckband;
- an eyewear device communicatively coupled with the neckband, wherein at least one of the neckband and the eyewear device measures an electrical signal associated with a user's heart activity;
- a light source optically coupled to a light detector, wherein the light source and the light detector are located on at least one of the neckband and the eyewear device, and measure an optical signal associated with the user's heart activity;
- and
- a controller configured to determine a heartrate of the user based at least in part on the electrical signal and the optical signal.
A heartrate monitor device comprising:
- a neckband;
- a light source located on the neckband;
- a light detector located on the neckband and optically coupled to the light source, wherein light is transmitted through a portion of the user's neck tissue and the light detector is configured to measure an optical signal;
- a first electrode and a second electrode located on the neckband, wherein the first electrode and the second electrode are secured to the user's neck and configured to measure an electrical signal;
- and
- a controller configured to determine a heartrate of the user based at least in part on the electrical signal and the optical signal.
A heartrate monitor device comprising:
- a neckband;
- an eyewear device communicatively coupled with the neckband and configured to provide an adjusted reality environment to a user, wherein at least one of the neckband and the eyewear device measures a signal associated with the user's heart activity;
- and
- a controller configured to determine a heartrate of the user based at least in part on the signal.
