US 2020/0272240 A1 · Motion and Gesture Input from a Wearable Device

Abstract

This relates to a device that detects a user's motion and gesture input through the movement of one or more of the user's hand, arm, wrist, and fingers, for example, to provide commands to the device or to other devices. The device can include a plurality of myoelectric sensors configured to detect one or more electrical signals from a body part of a user indicative of one or more movements. A plurality of signals indicative of the detected one or more electrical signals may be generated. The device may also include a wireless communication transmitter configured to communicate with a peripheral device and a processor. The processor may be configured to receive the plurality of signals from the plurality of myoelectric sensors, use the plurality of signals together to determine a gesture, and communicate one or more of: the plurality of signals and the gesture to the peripheral device.

Dependent claims

An optical sensing device, comprising:

a housing;
and
a display disposed within the housing;
a set of light emitters included in the housing of the optical sensing device, wherein a first light emitter of the set of light emitters is configured to emit a first wavelength of light toward a user's body part and a second light emitter of the set of light emitters is configured to emit a second wavelength of light, different than the first wavelength of light, toward the user's body part;
a set of optical sensors included in the housing of the optical sensing device, configured to detect reflections of the first and second wavelengths of light from the user's body part;
and
a processor configured to determine a difference between the detected reflections of the first and second wavelengths of light, and to identify motion artifacts using the determined difference between the detected reflections of the first and second wavelengths of light.
