The touch device includes a display unit, first infrared receivers, first infrared emitters, second infrared receivers, second infrared emitters, a storage unit, and motors. The first infrared receivers and the first infrared emitters are arranged on a first side of the display unit, and the second infrared receivers and the second infrared emitters are arranged on a second side of the display unit. The storage unit stores a table recording a relationship between identification and set of coordinates of the infrared receivers. The method includes: controlling motors to drive infrared emitters and infrared receivers to rotate; determining whether electrical signals comprising the identification of one first infrared receiver and one second infrared receiver are simultaneously received; if yes, determining the set of coordinates of the touch spot; determining an icon and determining the corresponding function corresponding to the touch spot."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch device and touch method","description":"A touch method is applied in a touch device.
