The optical touch device includes a panel, a left-side sensor and a right-side sensor. The operation method includes the steps of: sensing a sensing waveform on the panel; determining the number of peaks of the sensing waveform to control the optical touch device to be switched to a gesture mode or a touch mode; estimating a first variance according to a first sensing waveform sensed by the left-side sensor and a second variance according to a second sensing waveform sensed by the right-side sensor when the optical touch device is operating in the gesture mode; and determining the gesture made by the user according to the first variance and the second variance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical touch devices and operation method thereof","description":"An embodiment of the disclosure provides an operation method for an optical touch device.
