Abstract: A method for a device to prompt seat selection is provided. The method includes: receiving a viewing site identification (ID); determining a seat ID associated with the viewing site ID and one or more seat parameters corresponding to the seat ID based on a database; calculating an angle between a line segment and a plane of a viewed area based on the seat parameters, wherein the line segment connects a seat corresponding to the seat ID to a preset position of the viewed area; selecting the seat ID as a target seat ID if the calculated angle is in a preset range; and outputting the target seat ID.
