摘要： This document describes techniques and devices for detecting twist input with an interactive cord. An interactive cord may be constructed with one or more conductive yarns wrapped around a cable in a first direction (e.g., clockwise), and one or more conductive yarns wrapped around the cable in a second direction that is opposite the first direction (e.g., counter-clockwise). A controller measures one or more capacitance values associated with the conductive yarns. In response to detecting a change in the one or more capacitance values, the controller determines that the change in the capacitance values corresponds to twist input caused by the user twisting the interactive cord. Then, the controller initiates one or more functions based on the twist input, such as by controlling audio to a headset by increasing or decreasing the volume, scrolling through menu items, and so forth.

摘要： An electronic device includes a touch cord for inputting user commands by hand gesture. The touch cord includes a plurality of conductive sensing lines braided with a plurality of non-conductive lines such that the plurality of conductive sensing lines enable reception of touch inputs that cause a change in capacitance to one or more of the conductive sensing lines. The touch inputs including continuous hand gesture inputs, discrete motion hand gesture inputs, and discrete grasp hand gesture inputs. The electronic device is configured to obtain touch data associated with the touch cord, process the touch data according to one or more trained machine-learned models to identify gesture inputs including continuous hand gesture inputs, discrete motion gesture inputs, and discrete grasp hand gesture inputs. The electronic device can be operated according to one or more user commands associated with the hand gesture inputs.

摘要： A wearable computing device such as a head-mounted display (HMD) may be equipped with a magnetometer for detecting presence and motion of a hand-wearable magnet (HWM). The HMD may analyze magnetic field measurements of the magnetometer to determine when the HWM moves within a threshold distance of the magnetometer, and may thereafter determine one or more patterns of motion of the HWM based the magnetic field measurements. The HMD may operate in a background detection state in order to determine a background magnetic field strength and to monitor for magnetic disturbances from the HWM. Upon occurrence of a trigger event corresponding to magnetic disturbance above a threshold level, the HMD may transition to operating in a gesture detection state in which it analyzes magnetometer measurements for correspondence with known gestures. Upon recognizing a known gesture, the HMD may carry out one or more actions based on the recognized known gesture.

摘要： This document describes techniques directed to a scalable gesture sensor for wearable and soft electronic devices. The scalable gesture sensor is integrated into an object such as a wearable garment or a large-surface embedded system to provide a touch-sensitive surface for the object. The sensor includes a repeated localized crossover pattern formed by the same few sensor lines, resulting in the same two conductive lines having multiple crossover points across the touch-sensitive surface. The repeated crossover pattern enables detection of the occurrence and relative direction of a swipe gesture based at least on a repeated sequence of capacitance changes over a set of conductive lines in the repeated crossover pattern. Also, the scalable gesture sensor is computationally simple, uses low power, and is uniquely scalable to cover a large area with few electrodes.

摘要： This document describes authentication using an interactive cord. An interactive cord includes a cable, and a fabric cover that covers the cable. The fabric cover includes one or more conductive threads woven into the fabric cover to form one or more capacitive touchpoints which are configured to enable reception of touch input that causes a change in capacitance to the one or more conductive threads. The interactive cord can be used to authenticate a user. For example, rather than using a password entered into a computing device, a touch input pattern can be provided to interactive cord that is coupled to the computing device to authenticate the user.

摘要： This document describes techniques and devices for an interactive cord with resistance touchpoints. An interactive cord includes an audio wire, and a fabric cover that covers the audio wire. The fabric cover includes at least one conductive thread integrated into the fabric cover to form at least one touchpoint at which the conductive thread makes contact with the audio wire when the touchpoint is pressed. The contact of the conductive thread with the audio wire creates a resistance value that is mapped to a control. The resistance value is based on a resistance of the conductive thread and a length of the conductive thread from a base of the interactive cord to the touchpoint. The resistance value is detectable by a controller implemented at a computing device that is coupled to the interactive cord. In response to detection of the resistance value, the controller triggers the control.

摘要： This document describes an interactive cord with integrated light sources. An interactive cord includes a cable, a cover that covers the cable, and a plurality of light sources integrated into the cover. The cover includes capacitive touchpoints that enable reception of touch input that causes a change in capacitance to one or more conductive threads effective to trigger a function at a computing device. Different conductive threads can be used at different capacitive touchpoints to trigger different functions. The light sources are configured to indicate a position of a respective capacitive touchpoint on the cover.
