Abstract: Disclosed is a display apparatus and a method for digital manipulation of a virtual user interface in virtual environments. The display apparatus includes a light source, tracking means, and a processor configured to control the light source to project the virtual user interface, and process tracking data from the tracking means to detect the proximity of an interaction element, such as a user's hand, to an invisible segment of a virtual widget within the virtual user interface. Upon proximity detection, the light source is activated to display the virtual widget. The processor then determines if the segment has been activated and subsequently processes any positional changes of the interaction element to adjust the virtual user interface accordingly. This adjustment is performed in accordance with predefined visual effects that correspond to the activated segment, enabling intuitive and dynamic user interaction.
