Problems solved by technology

In another example, it can be difficult to press small buttons or use touchscreen functions when the user's hands are otherwise occupied or unavailable (e.g., while wearing gloves, holding objects, holding a child's hand, driving, etc.)
In other examples, device interaction may be restricted in a variety of other ways

Embodiment Construction

[0021] In the following description of the examples, reference is made to the accompanying drawings, in which are shown by way of illustrations specific examples that may be practiced. It is to be understood that other examples may be utilized and structural changes may be made without departing from the scope of the respective examples.

[0022] This involves wearable devices with optical sensors that can be used to recognize gestures of the user wearing the device. In one example, one or more light sources may be positioned on the back or skin-facing side of a wearable device such as a watch, wristband, armband, legband, chestband, headband, or the like. Optical sensors can be positioned near one or more light sources on the same side of the wearable device. During operation, light may be emitted from one or more light sources and sensed using optical sensors. Changes in sensed light caused by movement of a user wearing the device can be used to recognize user gestures. F...

Abstract

A wearable device with an optical sensor is disclosed that can be used to recognize gestures of a user wearing the device. Light sources can be positioned on the back or skin-facing side of a wearable device, and an optical sensor can be positioned near the light sources. During operation, light can be emitted from the light sources and sensed using the optical sensor. Changes in the sensed light can be used to recognize user gestures. For example, light emitted from a light source can reflect off a wearer's skin, and the reflected light can be sensed using the optical sensor. When the wearer gestures in a particular way, the reflected light can change perceptibly due to muscle contraction, device shifting, skin stretching, or the distance changing between the optical sensor and the wearer's skin. Recognized gestures can be interpreted as commands for interacting with the wearable device.

Description

technical field [0001] The present invention relates generally to optical sensors, and more particularly to the use of optical sensors in wearable devices to recognize gestures of the wearer. Background technique [0002] Optical sensors have been incorporated into various user devices to provide enhanced functionality and new opportunities for user interaction. Optical sensors for detecting light, detecting proximity, taking pictures, etc. have been incorporated into mobile phones (e.g., smartphones), tablet computers, wearable devices (e.g., watches, glasses, etc.), and other computing devices, allowing Software developers create engaging software applications ("apps") for entertainment, productivity, wellness, and the like. In some cases, optical sensors work in conjunction with various other input mechanisms for interacting with devices (eg, touch screens, buttons, microphones for voice commands, etc.). [0003] However, many devices may have limited device interaction...
