Abstract: A user interface apparatus is provided that includes a computer arrangement coupled to a data memory arrangement for processing, accessing and storing data, and a display arrangement for receiving graphics data from the computer arrangement to present as graphical images to a user. The computer arrangement, when in operation, instructs the display arrangement to present at least one tesseract with overlayed icons onto facets or layers of the at least one tesseract that represent a menu of executable options that can be invoked by the user. The user interface apparatus is beneficially capable, when in operation, of displaying text, images, presentations. Moreover, the user interface apparatus is capable, when in operation, of supporting personalized interactivity through using machine learning (ML) or artificial intelligence (AI) algorithms executed on the computer arrangement, wherein the personalized interactivity is adapted to take into account personal characteristics and nuances of the user.
