摘要： Systems, devices, and methods that integrate eye tracking capability into scanning laser projector (“SLP”)-based wearable heads-up displays are described. At least one narrow waveband laser diode is used in an SLP to define one or more portion(s) of a visible image. At least one corresponding narrow waveband photodetector is aligned to detect reflections of the portion(s) of the image from features of the eye. A holographic optical element (“HOE”) may be used to combine the image and environmental light into the user's “field of view.” Three narrow waveband photodetectors each responsive to a respective one of three narrow wavebands output by the RGB laser diodes of an RGB SLP are aligned to detect reflections of a projected RGB image from features of the eye.

摘要： Systems, devices, and methods for eyebox expansion by exit pupil replication in scanning laser-based wearable heads-up displays (“WHUDs”) are described. The WHUDs described herein each include a scanning laser projector (“SLP”), a holographic combiner, and an optical replicator positioned in the optical path therebetween. For each light signal generated by the SLP, the optical replicator receives the light signal and redirects each one of N>1 instances of the light signal towards the holographic combiner effectively from a respective one of N spatially-separated virtual positions for the SLP. The holographic combiner converges each one of the N instances of the light signal to a respective one of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.

摘要： Systems, devices, and methods that are effected in or by an electronic device in response to establishing and/or terminating a physical communications link are described. An electronic device may be entered into deep sleep and may include a power control circuit that activates the device out of deep sleep in response to establishing a physical communications link with a source of electric power, such as another electronic device. Either in combination with or separate from this, an electronic device may establish wireless communications with another electronic device in response to establishing and terminating a physical communications link with the other electronic device. The physical communications link may be used to transfer device identity data from one device to the other and thereby bypass the cumbersome “discovery” process common to conventional wireless communication techniques. Portable electronic devices and personal computing devices that are operative to perform the above are described.

摘要： There is disclosed a muscle interface device for use with controllable connected devices. In an embodiment, the muscle interface device comprises a sensor worn on the forearm of a user, and the sensor is adapted to recognize a plurality of gestures made by a user to interact with a controllable connected device. The muscle interface device utilizes a plurality of sensors, including one or more of capacitive EMG sensors and an IMU sensor, to detect gestures made by a user. Other types of sensors including MMG sensors may also be used. The detected user gestures from the sensors are processed into a control signal for allowing the user to interact with content displayed on the controllable connected device.

摘要： Systems, devices, and methods that integrate eye tracking capability into scanning laser projector (“SLP”)-based wearable heads-up displays are described. An infrared laser diode is added to an RGB SLP and an infrared photodetector is aligned to detect reflections of the infrared light from features of the eye. A holographic optical element (“HOE”) may be used to combine visible light, infrared light, and environmental light into the user's “field of view.” The HOE may be heterogeneous and multiplexed to apply positive optical power to the visible light and zero or negative optical power to the infrared light.

摘要： Systems, methods, and computer program products for interacting with electronically displayed presentation materials are described. A display system includes, at least, a digital processor, an electronic display, and a non-transitory processor-readable storage medium into which is loaded a computer program product that includes, at least, processor-executable instructions and/or data. The processor-executable instructions and/or data, when executed by the processor, cause the display system to respond to user inputs indicative of pointer commands and magnification setting commands. In response to such commands, the display system causes; i) a dynamic cursor to display over top of content on the electronic display; and ii) a digital copy image of the content to be displayed over top of the content on the electronic display, the digital copy image displayed at a greater magnification level than the content.

摘要： Systems, articles, and methods perform gesture identification with limited computational resources. A wearable electromyography (“EMG”) device includes multiple EMG sensors, an on-board processor, and a non-transitory processor-readable memory that stores data and/or processor-executable instructions for performing gesture identification. The wearable EMG device detects and determines features of signals when a user performs a physical gesture, and processes the features by performing a decision tree analysis. The decision tree analysis invokes a decision tree stored in the memory, where storing and executing the decision tree may be managed by limited computational resources. The outcome of the decision tree analysis is a probability vector that assigns a respective probability score to each gesture in a gesture library. The accuracy of the gesture identification may be enhanced by performing multiple iterations of the decision tree analysis across multiple time windows of the EMG signal data and combining the resulting probability vectors.
