Abstract: User biometric information based authentication techniques are provided for a wearer of a near-eye display device in engagement with multimedia content and/or access to restricted data. Biological and/or behavioral biometric information associated with the user may be captured through sensors and similar devices integrated or communicatively coupled to the near-eye display device. The biological biometric information may include data associated with a user's face, fingerprint, palmprint, iris, retina, cardio-electrical signals, etc. The behavioral biometric information may include data associated with a user's movement, gait, gesture(s), voice, etc. An authentication technique may be automatically select one based on environmental conditions (e.g., noise or light levels). Near-eye display device may detect continuous wearing by the user and refresh or continue authentication following a period of non-use or between two different authenticated sessions.

Abstract: Systems and methods are provided for using sensor data from a wrist-wearable device to monitor image-capture trigger conditions for determining when to capture images using an imaging device of a head-wearable device. One example method includes receiving, from a wrist-wearable device communicatively coupled to a head-wearable device, sensor data; and determining, based on the sensor data received from the wrist-wearable device, whether an image-capture trigger condition for the head-wearable device is satisfied. The method further includes in accordance with a determination that the image-capture trigger condition for the head-wearable device is satisfied, instructing an imaging device of the head-wearable device to capture image data.

Abstract: Methods and systems of coordinating display of biometric data at a head-worn wearable device based on sensor data from a wrist-wearable device are disclosed. A method includes receiving an indication that a user of a head-worn wearable device is performing a physical activity. The head-worn wearable device includes a light-emitting diode visible to the user while wearing the head-worn wearable device and is in communication with a wrist-wearable device worn by the user. The wrist-wearable device is configured to sense biometric data for the user during the physical activity. The method includes, after receiving the indication and while the user is performing the activity, in accordance with a determination that the biometric data satisfies a physiological-based threshold indicating that information about the biometric data would assist the user in performing the physical activity, causing the head-worn wearable device to present, via the light-emitting diode, the information about the biometric data.

Abstract: Systems and methods are provided for determining when to cease capturing video via a head-worn wearable device. The method includes capturing, via a head-worn wearable device that includes a camera, video data. The method further includes, while capturing the video data, monitoring sensor data indicating one or both of (i) a position of the head-worn wearable device and (ii) a position of a wrist-wearable device that is communicatively coupled with the head-worn device to determine when to cease capturing the video data. The method further includes, in accordance with a determination that at least some of the sensor data indicates that one or both of (i) a video-capturing precondition is not present at the head-worn wearable device and (ii) a video-viewing precondition is present at the wrist-wearable device, ceasing to capture the video data and causing the video data to be displayed on a display of the wrist-wearable device.

Abstract: Systems and methods are provided for coordinated video streaming and messaging using a wrist-wearable device and a head-worn wearable device. The method includes receiving an instruction to use a camera of a head-worn wearable device to capture video data. The method further includes, after receiving the instruction to use the camera of the head-worn wearable device to capture the video data, receiving, at a wrist-wearable device that is in communication with the head-worn wearable device, electronic messages from a viewer of the video stream and monitoring sensor data indicating one or both of a position of the head-worn wearable device and (ii) a position of the wrist-wearable device to determine when to display the electronic messages. The method also includes, in accordance with a determination that the sensor data indicates that a message-viewing precondition is present, displaying the electronic messages from the viewer of the video stream.

Abstract: A device is provided, including a frame, providing mechanical support to at least two eyepieces, a capacitive sensor mounted on the frame, an inertial measurement sensor mounted on the frame, and a flexible circuit component inside the frame and electrically coupling the capacitive sensor and the inertial measurement sensor with a processor circuit and a memory circuit inside the frame.
