Devices that activate spooky sounds, lights, or movements when someone approaches are increasingly popular during the Halloween season. An example includes a prop skeleton that begins to cackle and wave its arms when a person walks by on Halloween night. This functionality relies on detecting movement within a specified range.
The incorporation of this technology into seasonal ornamentation significantly enhances the user experience by providing an element of surprise and interaction. Historically, manually triggered or static displays were the norm, but the automated nature of movement-activated props offers a more dynamic and engaging form of decoration. This also serves as a deterrent to unwanted trespassers or vandals during the holiday period.
