Machine segmentation of sensor measurements and derivatives in virtual motor exams

A computer-readable medium comprising processor-executable instructions that, when executed by one or more processors of a wearable device, cause the wearable device to perform operations comprising:

• accessing, by the wearable user device, exam information identifying:
• (i) a first timing indicator associated with a first time, (ii) a second timing indicator associated with a second time, and (iii) a virtual motor exam type of a virtual motor exam;
• accessing, by the wearable user device, signal data obtained by the wearable user device during a time period bounded by the first time and the second time;
• determining, by the wearable user device and based on the virtual motor exam type, a first signal data type for segmenting the signal data, the first signal data of the first signal data type being output by a first sensor of the wearable user device during the time period;
• determining, by the wearable user device, a context window within the time period by at least:
• selecting a historical signal profile of the first signal data type, the historical signal profile derived from previous occurrences of the virtual motor exam;
• and
• comparing the first signal data to the historical signal profile to identify a third time corresponding to a beginning of the context window and a fourth time corresponding to an end of the context window of the context window;
• segmenting, by the wearable user device, a portion of the signal data received during the context window;
• and
• generating, by the wearable user device, a virtual motor exam data package based on the portion of the signal data and the exam information.

A computer-implemented method, comprising:

• receiving, at an input device of a wearable user device, a first user input identifying a beginning of a first time period in which a virtual motor exam is conducted;
• receiving, at the input device of the wearable user device, a second user input identifying an end of the first time period;
• accessing, by the wearable user device and based on the virtual motor exam, first signal data output by a first sensor of the wearable user device during the first time period;
• determining, by the wearable user device, a context window within the first time period based on the first signal data and a virtual motor exam type associated with the virtual motor exam, the context window defining a second time period that is within the first time period;
• determining, by the wearable user device, second signal data output by a second sensor of the wearable user device during the second time period;
• and
• associating, by the wearable user device, the second signal data with the virtual motor exam.
