Abstract
A method for positioning a sensor configured to receive biometric signals includes receiving a biometric signal using a biometric sensor at a first position, the biometric signal comprising a set of raw biometric signal data. In some implementations, signal analysis is used to determine whether at least one signal criteria is met and to determine whether the biometric sensor is moved from the first position to a second position.
Claims20
A head-mounted display device, comprising:
- a display unit;
- a sensor configured to receive a biometric signal, the biometric signal comprising one or more sets of biometric signal data, each set of biometric signal data corresponding to a different position of the sensor;
- a housing configured to enable the sensor to retract into the housing along a first axis of motion;
- a motion track disposed on the housing, wherein the motion track is configured to guide movement of the sensor along a second axis of motion and a third axis of motion;
- a motor configured to move the sensor along the first axis of motion, the second axis of motion, and the third axis of motion as provided by the housing and the motion track;
- and
- a processor communicatively coupled to the sensor and the motor and configured to:
- compute a noise component for each of the one or more sets of biometric signal data;
- compute a set of signal-to-noise ratios (SNRs) for each of the one or more sets of raw biometric signal data;
- and
- determine, based on computing the set of SNRs, a position for the sensor, the position corresponding to a greater or maximum SNR from the set of SNRs.

A method for positioning a sensor configured to receive biometric signals, comprising:
- receiving a biometric signal using a biometric sensor at a first position, the biometric signal comprising a set of raw biometric signal data;
- computing a noise component of the biometric signal;
- performing signal analysis on the biometric signal;
- determining, based on the signal analysis, that no criteria are met;
- in response to determining that no signal criteria are met:
- retracting, via a motor, the biometric sensor to a retracted position, wherein the biometric sensor is disposed in a housing;
- moving, via the motor, the biometric sensor from the first position to a second position in a first direction along a motion track configured to guide movement of the biometric sensor, wherein the biometric sensor is in the retracted position during movement;
- receiving a second biometric signal using the biometric sensor at the second position;
- performing a second signal analysis on the second biometric signal;
- determining, based on the second signal analysis, that at least one signal criteria is met;
- and
- in response to determining that the at least one signal criteria is met, moving, via the motor, the biometric sensor to a third position, wherein the biometric sensor is moved in a second direction.
