The visual memories emerge from the past on the visor just in certain environmental/temporal conditions as for example just in the dark, in the silence, no movements, same day it was taken.

Reference to isophone -> less external stimuli, more attention to the visual memory

Maybe capture audio too? parts of it? only the frequencies that matter most for the emotion part of the memory and less for the understanding of it.

Use hi speed digital cameras as primary input for the visual memory, give the possibility to the user to capture a given amount of memories each memory lasting a given amount of time.

The user can pause the "recording" of the memory keeping a button pressed (rough editing capability).

How the visual memory is going to be visualized? it has to live in a physical object, better if not a flat screen, better if a projection.
