Visual input is the primary means we humans consume information. We use while driving and reading and for everything else. Clenching to the data structures and information storage/encoding probably not the way forward.
in the terms of intelligence, it's just one of 6 senses. MEMS sensors, signal filters, and coding schemes (compression) are going strong, too. Touch is still problematic I understand.
In that regard, flexible LED screens could be interesting, using the photoeffect in the diodes like a camera, lighting the area at the same time and maybe integrate a resistive touch grid matrix, too.
