Abstract
Techniques and methods for evaluating an instance of a pre-defined task being performed by a user with a handheld tool. In an embodiment, measurement information is stored to a log based on sensor data generated during motion of the handheld tool. Based on a definition of a task and the logged measurement information, a determination is made as to whether the sensed motion corresponds to a performance of at least some action of the defined task. In another embodiment, the definition of the task includes or otherwise corresponds to criteria information. The performance of the task is evaluated based on the criteria information to detect bradykinesia or some other unintentional muscle performance of the user.
