Abstract: Systems, devices, and methods relate to generation of augmented images using virtual content that is part of an augmented reality presentation and images of a scene captured via an image sensor. A wearable heads-up display (WHUD) may present an augmented reality presentation with virtual content projected into a field of view of a scene, while an image sensor captures images of the scene. The image sensor may be part of the WHUD or part of a separate device, for instance part of a smartphone. A wearer may view a scene via the WHUD and capture an image of all or a portion of the scene, for instance via a camera of either the WHUD or a separate device. An application monitors the virtual content and can generate an augmented image, which can be transmitted/printed, replicating the augmented reality experience and/or adding customized messages to the resulting augmented image.

Abstract: Systems, articles, and methods for improved capacitive electromyography (“EMG”) sensors are described. The improved capacitive EMG sensors include one or more sensor electrode(s) that is/are coated with a protective barrier formed of a material that has a relative permittivity εr of about 10 or more. The protective barrier shields the sensor electrode(s) from moisture, sweat, skin oils, etc. while advantageously contributing to a large capacitance between the sensor electrode(s) and the user's body. In this way, the improved capacitive EMG sensors provide enhanced robustness against variations in skin and/or environmental conditions. Such improved capacitive EMG sensors are particularly well-suited for use in wearable EMG devices that may be worn by a user for an extended period of time and/or under a variety of skin and/or environmental conditions. A wearable EMG device that provides a component of a human-electronics interface and incorporates such improved capacitive EMG sensors is described.

Abstract: Systems, devices, and methods are disclosed for enabling private communication between head-mounted displays. A first user dons a first head-mounted display. The first head-mounted display authenticates that the first user is authorized to view information displayed by the first head-mounted display. In response to positive authentication, the first head-mounted display displays the information to the first user. The first user inputs a selection command via an input interface, such as, for example, gazing at particular information, to select some of the displayed information. The first head-mounted display generates a message based on the user selection, which may be encrypted by the first head-mounted display prior to transmission. The first head-mounted display transmits the message to a second head-mounted display, such that the second head-mounted display displays the message to an eye of a second user wearing the second head-mounted display.

Abstract: Wearable electronic devices having a selfie camera are described herein. The wearable electronic devices include a body defining an aperture that is sized and shaped to receive a finger of a user. The wearable electronic device also includes a processor housed in the body, an input device arranged on an outer surface of the body and communicatively coupled to the processor to receive an input from a second finger of the user, an optical sensor to capture an image in response to the input from the second finger of the user, a transmitter communicatively coupled to the processor to transmit the image to an external electronic device, and optionally a power source communicatively coupled to the processor and the transmitter to provide power to at least the processor and the transmitter.

Abstract: Systems, articles, and methods for surface electromyography (“EMG”) sensors that combine elements from traditional capacitive and resistive EMG sensors are described. For example, capacitive EMG sensors that are adapted to resistively couple to a user's skin are described. Resistive coupling between a sensor electrode and the user's skin is galvanically isolated from the sensor circuitry by a discrete component capacitor included downstream from the sensor electrode. The combination of a resistively coupled electrode and a discrete component capacitor provides the respective benefits of traditional resistive and capacitive (respectively) EMG sensor designs while mitigating respective drawbacks of each approach. A wearable EMG device that provides a component of a human-electronics interface and incorporates such capacitive EMG sensors is also described.

Abstract: Systems, devices, and methods for wearable computer systems are described. A wearable heads-up display (“WHUD”) is implemented as a peripheral to a wearable electronic band worn on a limb of the user. The majority (or all) of the application storage and processing is performed on the band instead of on the WHUD, and therefore the WHUD does not include all of the hardware infrastructure necessary for application storage and processing. This significantly reduces the bulk of the WHUD and enables more aesthetically pleasing WHUD designs. Graphics processing is also performed on the band instead of on the WHUD. In some implementations, rasterized display data is wirelessly transmitted from the band to the WHUD using an ultra-wideband wireless communication scheme. Gesture-based control of content displayed by the WHUD is enabled by sensors on-board the band itself or by a third wearable component in communication with the band.

Abstract: Systems, devices, and methods that implement state machine models in wearable electronic devices are described. A wearable electronic device stores processor-executable gesture identification instructions that, when executed by an on-board processor, enable the wearable electronic device to identify one or more gesture(s) performed by a user. The wearable electronic device also stores processor-executable state determination instructions that, when executed by the processor, cause the wearable electronic device to enter into and transition between various operational states depending on signals detected by on-board sensors. The state machine models described herein enable the wearable electronic devices to identify and automatically recover from operational errors, malfunctions, or crashes with minimal intervention from the user.
