Integrated Biometric Sensing and Display Device
First Claim
1. An apparatus for measuring biometric data of a user on a device secured to a user, the apparatus comprising:
- a galvanic skin response sensor measuring a state of the user associated with physical activity, emotional arousal or other conductivity changing event;
an ambient temperature sensor measuring ambient temperature associated with surroundings of the user, the ambient temperature providing contextual data about biometric measurements of the user;
a skin temperature sensor measuring temperature of the user, the measured temperature used to measure the biometric data of the user;
a motion sensor measuring motion of the user, the motion sensor including a multi-axis accelerometer measuring a magnitude and direction of acceleration of the motion;
a light emitter transmitting light to body of the user, the emitted light of a particular wavelength, geometry, intensity and mode;
an optical sensor receiving light passed by the wavelength selection filter and converting the received light to data; and
a processor receiving data from the galvanic skin response sensor, the ambient temperature sensor, the skin temperature sensor, the motion sensor and the optical sensor and computing the biometric data of the user, the biometric data including an offset for motion experienced by at least one sensor, an offset for skin pigmentation of the user, the skin pigmentation effecting light received by the optical sensor and accounting for other sources of personal variance in light reflectance characteristics, an offset for geometry of the light emitter.

Abstract
A biometric device configured to be attached to a portion of a body of a user measures biometric data of the user. The device includes an optical emitter, a wavelength filter, an optical sensor and a processor, for sending a light to the body of a user, receiving light received from the user, filtering and processing it to measure biometric data of the user, including for example, heart rate and blood flow rate. In addition, the biometric device may include other sensors, such as a galvanic skin response sensor, an ambient temperature sensor, skin temperature, motion sensor, etc., to enable the biometric device to measure arousal or conductivity changing events, ambient temperature, user temperature and motion associated with the user. Additionally, information from each sensor may be used to further filter noise in one or more signals received by the sensors to provide biometric data to the user.
