A wearable device includes an analog-to-digital converter (ADC) configured to digitize biopotential signals received from biopotential-signal-sensing channels. The wearable device also includes a supplementary processor that samples the digital biopotential signals from the ADC. The supplementary processor sends the digital biopotential signals to a buffer until a determination is made that a particular number of the digital biopotential signals is stored in the buffer. Additionally, the supplementary processor transmits an indication to a primary processor that the particular number of the digital biopotential signals is stored in the buffer. In addition to the ADC and the supplementary processor, the wearable device includes the aforementioned primary processor. The primary processor is configured to operate in a low-power mode before receiving the indication and, after receiving the indication, process the particular number of digital biopotential signals from the buffer to detect in-air hand gestures performed by a user of the wearable device.

Coprocessor for biopotential signal pipeline, and systems and methods of use thereof

The various implementations described herein include methods and systems for providing a force dimension to interface elements. In one aspect, a method includes (i) communicatively coupling a wearable device that includes electromyography (EMG) sensors with an activatable device that includes a mechanical user interface element; (ii) in accordance with an activation of the user interface element, obtaining data from the EMG sensors that corresponds to the activation; (iii) determining, based on the data from the EMG sensors, whether the activation includes an activation force that meets predefined criteria; (iv) in accordance with a determination that the activation force meets the predefined criteria, causing execution of a first function corresponding to the user interface element; and (v) in accordance with a determination that the activation force meets the predefined criteria, causing execution of a second function corresponding to the user interface element.
