Abstract
A scratching detection system includes a sensor and processor. The sensor is configured to detect acceleration corresponding to movement of a person's hand and is configured to output a first signal including a detected value corresponding to the acceleration in a first cycle. The processor is configured to acquire the first signal and to detect a scratching behavior of the person in a second cycle based on a plurality of parameters. The second cycle includes a plurality of the first cycles. The plurality of parameters includes a first occurrence count and a first consecutive count. The first occurrence count is a number of times an absolute value of the detected value exceeds a threshold value in the second cycle. The first consecutive count is a maximum value of a number of times that the absolute value of the detected value consecutively exceeds the threshold value in the second cycle.
