Interactive projectors are devices that allow users to project images or videos onto a surface while also enabling interaction with the projected content. They use special technology to detect touch or gestures, allowing users to manipulate the display as if it were a touchscreen. This makes them useful in classrooms, meetings, and presentations, where collaboration and engagement are essential. These projectors can turn any flat surface, like a wall or table, into an interactive workspace. They often come with software that supports various applications, making them versatile tools for education and business. Popular brands include Epson and BenQ, which offer different models to suit various needs.
