With an evaluation device, a sleep level of a person being measured is discriminated based on a signal input from a body motion sensor. With the evaluation device, when a go-to-bed button is operated at time T, time Tis stored as the go-to-bed time. When a good-night button is operated at time T, discrimination of sleep level is started. Thereafter, when the good-night button again is operated at time T, the discrimination of sleep level ends.

Sleep evaluation device and sleep evaluation method

A measurement device is provided with a sensor for detecting body motion of a subject and a CPU for executing processing for generating display data. The CPU includes a first discrimination unit for discriminating a sleeping state of the subject for each unit period, based on a sensor signal output from the sensor, a second discrimination unit for discriminating a level of the sleeping state of a predetermined period consisting of a predetermined number of continuous unit periods, based on the sleeping state for each unit period, a decision unit for deciding a display mode for each predetermined period, according to the level of the sleeping state of the predetermined period, and a generation unit for generating display data for displaying the level of the sleeping state of the subject in the predetermined period on a display device with a graph along the time axis.
