Each capsule unit measures 1.2 meters by 1.2 meters and is around 2.1 meters deep. An infrared camera and a directional microphone have been installed above the heads of the prone guests. A sensor beneath the bed sheet detects body movements. The devices are designed to record sleeping hours, the number of rolls and apneas, snoring volume and other details of the slumbers. Guests can receive reports about their sleep afterwards. The anonymous data will be sold to companies with the guests' consent. Bedclothes and food items designed to promote sound sleep are sold at the hotel, along with freebies. Guests who try these items can provide feedback to the manufacturers. "We hope that the analysis results will be used to verify the products' effectiveness and to develop new goods," said a project representative. The hotel, operated by Nine Hours, is housed in an NTT Data commercial complex.
