A gesture sensing device includes a single light source and a multiple segmented single photo sensor, or an array of photo sensors, collectively referred to herein as segmented photo sensors. A light modifying structure relays reflected light from the light source onto different segments of the segmented photo sensors. The light modifying structure can be an optical lens structure or a mechanical structure. The different segments of the photo sensor sense reflected light and output corresponding sensed voltage signals. A control circuit receives and processes the sensed voltage signals to determine target motion relative to the segmented photo sensor.

A gesture sensing device includes a multiple segmented photo sensor and a control circuit for processing sensed voltages output from the sensor. The control circuit processes the sensed voltage signals to determine target motion relative to the segmented photo sensor. The control circuit includes an algorithm configured to calculate one of more differential analog signals using the sensed voltage signals output from the segmented photo sensors. A vector is determined according to the calculated differential analog signals, the vector is used to determine a direction and/or velocity of the target motion.

A gesture sensing device having a single illumination source is disclosed. In one or more implementations, the gesture sensing device includes a single illumination source configured to emit light and a light sensor assembly configured to detect the light reflected from an object and to output time dependent signals in response thereto. The gesture sensing device also includes a processing circuit coupled to the light sensor assembly and configured to analyze the time dependent signals received from the light sensor assembly to determine object directional movement proximate to the light sensor assembly.

A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.

A portable electronic device include one or more electrodes for calculating distances and rotational angles between the device and the user is disclosed. Based on the calculated distances and rotational angles, a physical activity of the user can be determined. Additionally, the calculated distances and rotational angles can be used for compensation of optical artifacts in one or more signals detected by the device. User movement or physical activity can introduce optical artifacts, which can lead to erroneous determination of the one or more characteristics. The calculated distances and rotational angles can be used to reduce or remove the optical artifacts, leading to a more accurate determination of the one or more characteristics of the user.
