Title: Processing system for interactive, personal and idiosyncratic control of images and devices
Inventor: MACRI VINCENT J
IPC: G09B19/00
Filed: 2000-05-02
Granted: 2012-06-19
Abstract: A processing system apparatus is arranged to receive user inputs differentiated from other users' inputs and to provide variable outputs which are individualized to each user. The processing system apparatus receives and processes inputs and displays images whose simulated physical movements are interactively controlled by each user's individual, personal, idiosyncratic inputs. The apparatus accepts such user-specific inputs into an "open" knowledge base and processes such inputs to produce user-specific, idiosyncratic outputs. In effect, the knowledge base learns from the user and the user learns from the feedback produced by the processing system apparatus. The processing system apparatus is further arranged so that as each user's successively transmitted inputs are received, its knowledge base stores and integrates such inputs so that outputs, in the form of simulated movements by user controllable images represent processed, idiosyncratic, updated and on-going inputs.
