Hi, I believe they are talking about an electrode array which gives you feedback with leectrical impulses instead of pin mounted refreshable display. That is the one allusion or addendum to what the iphone already has through sound cues.
I find it interesting as it would allow, given the right resolution, to figure the street display not only in hotspots and points of interest but also in the actual topology of the place. There is a technology which uses the same principle whereas the rgb values, displayed in monochrome, allows the user to feel intensities on their fingertips. So the lighter the tone, the more intense the current. Now there are obvious battery hurdles in this mechanism, but when considering an lcd or the iphone screen, to be more precise, there is already a current going through. So if one used a conductive material which is also transparent, and robust, the solution could be well within current technology means. best --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
