John, do you think then there is a problem with using the word 'interface'? I can see a similarity between program language being converted to on off bits at an interface, and the EM radiation profile being converted to electric nerve impulse or signal in a device. But I have been considering the sensory system or device 'workings' to be an interface that converts the externally originating input into the internal product, which is a much broader concept. Perhaps I need to talk about the 'sensory interface' component of the larger 'reality interface'.
Re. Boston Dynamics 'spot': What is particularly interesting to me is the map of the obstacles generated from the cameras inputs ( generated using input of EM to the cameras.) Clearly the map is not the external reality. Nonessential information has been minimized and only where can and can't be safely stepped on is included, which is most important for locomotion of the robot. (Shown as two colour differentiation in a visual display product.)
