I was thinking about the beautiful red trumpet story I read as a child. It reminded me that, as an artist, I am always fascinated by the fact that when I ask, "What color is this?" one person's eyes might see aqua, one blue, and still another green!
As we are all uniquely composed, it follows that, we see differently in what I call our mind's eye. Therefore, to give a blind person the experience of the color red is not out of the realm of possibilities.
Who can define the mind's eye? The neurologist? The scientist? The psychologist? The artist? I believe it's the same sensory a sighted person uses when they close their eyes to try to recall a memory, The blind could be stimulated to use this and, given free reign and imagination without boundaries, it might be even more vivid and clearer than what a sighted person might "see." This is because the sighted person has the boundaries of past recollections and the information they have intellectually gathered in their lifetime. It's the same principal when we talk of going on faith and trusting that it is so, even though we cannot physically see it in the flesh. It is a feeling we internalize.

I have read, with some delay, your message in IEEE MultiMedia, April—June 2003, (vol. 10, no. 2), regarding "Computational Biometrics, Multimedia Analysis, and Security," and I'd like to send you some comments on it.
I fully agree with your opinion, in the sense that a good portion of the multimedia community is more focused on digital contents, whilst the biometrics community is focused on secure personal authentication. Nevertheless, these two fields—as you well now—are getting nearer and nearer. There are lots of examples, such as DRMs, content-on-demand, or multimedia security. This means that we will have to work together in research activities and in the development of applications for the multimedia market.
Following this, I have two proposals for IEEE Multimedia:
