Motion detection refers to the technology that identifies movement within a specified area and triggers an action in response. When applied to digital signage, motion sensors are embedded within the displays or in the surrounding area. These sensors detect when a person enters a defined space or interacts with the signage, prompting the screen to change content, show an advertisement, or even adjust the brightness.
For example, a display could show general content until someone approaches, at which point it switches to a targeted message or product promotion specifically designed for that audience.
How Does Motion Detection Work?
The technology behind motion detection usually relies on infrared sensors, cameras, or ultrasonic technology to detect changes in movement. Here’s a breakdown of how these elements work:
Cameras: Cameras use image recognition and artificial intelligence (AI) to detect movement and identify the type of interaction. This can include distinguishing between multiple people or identifying gestures.
