Others use the augmented reality (AR) to generate the illusion of a real projection on flat surfaces.
Depending on the type of application used, you may need a stable Wi-Fi connection or compatible devices to ensure smooth, uninterrupted streaming. These solutions are very useful for both entertainment and professional and educational environments, as they allow for efficient content sharing without the need for additional cables or physical projectors.
