Definition: Portalless refers to a system or process that is designed to eliminate or minimize the need for external inputs, such as input devices or software, in order to perform tasks. This can be achieved by using sensors, cameras, and other digital technologies to capture data directly from the environment without requiring any human intervention. In simpler terms, a portalless system would rely on sensors and other digital equipment to gather information about the surroundings, rather than relying solely on external inputs such as physical objects or manual actions.
