Abstract: An activity assistance system includes a video camera arranged to acquire video of a person performing an activity, an output device configured to output human-perceptible prompts, and an electronic processor programmed to execute an activity script. The script comprises a sequence of steps choreographing the activity. The execution of each step includes presenting a prompt via the output device and detecting an event or sequence of events subsequent to the presenting of the prompt. Each event is detected by performing object detection on the video to detect one or more objects depicted in the video and applying one or more object-oriented image analysis functions to detect a spatial or temporal arrangement of one or more of the detected objects. Each event detection triggers an action comprising at least one of presenting a prompt via the output device and and/or going to another step of the activity script.

Abstract: Aiming assistance is provided for assisting a user in aiming a ranged weapon at a target. The aiming assistance includes receiving telemetry information from one or more sensors, and determining an aim error based on the telemetry information. The aim error indicates of an error between a trajectory of the ranged weapon and an on target trajectory from the ranged weapon to the target. A somatosensation is provided to the user which is indicative of the aim error. This is done by operating haptic devices of a garment worn on an arm or wrist of the user to apply haptic sensation to skin of the arm or wrist. The haptic devices may be electrodes and the applied haptic sensation comprises transcutaneous electrical neurostimulation (TENS), or the haptic devices may be vibrators.

Abstract: A stimulation system may include a sensor configured to detect a physiological signal of a user, the physiological signal having a biomarker therein associated with a disorder of the user; a stimulator configured to deliver electrical stimulation to the user; and a hub device configured to receive the physiological signal from the sensor and to output a control signal to the stimulator. The control signal may cause the stimulator to deliver electrical stimulation to the user according to a stimulation protocol, the stimulation protocol treating the disorder. The hub device may be configured to output the control signal based on the biomarker of the received physiological signal. The hub device may be configured to generate another control signal for treating another disorder based on a biomarker not included in the physiological signal received from the sensor.
