Sleep Stage Classification Technology: Monitor Your Sleep Patterns: A tablet displaying an application for sleep stage classification. The screen is dark, with blue and pink hues, and features various graphs and charts related to sleep patterns. A red button labeled 'Disconnect' is visible at the bottom left of the screen, while a small icon resembling a bed or pillow is situated in the top-right corner. In the background, several lit candles are arranged on a table or shelf, with one partially obscured by a plant's leaves. The overall impression suggests that this image may be used as an advertisement for sleep monitoring technology.
