A Mask That Can Give You Superhuman Abilities
An anonymous reader writes "The students at Royal College of Art in London have developed masks that can increase your sight and hearing senses. They allow you to choose one conversation or one visual among a cluster of sounds and visuals, then hear or see the one which you want to. There are two masks developed by them: Eidos Vision and Eidos Audio. Eidos Audio allows a wearer to hear a specific conversation in a crowd and could be developed as a hearing aid and help ADHD sufferers. Eidos Vision improves vision allowing wearer to see 'time trails' similar to a timelapse photography."
my Guy Fawkes mask and its superpowers.
With Eidos being the name, users will expect interminably long cut scenes in-between short spurts of actually being able to use the product.

Oh joy. Tech that mimics the effects of magic mushrooms......

It also can't work well due to the ongoing gain control problems with speech amplification. Digitally managed gain control has been an amazing cluster !@#$ and a complete waste of processing power. You can't twitch the gain up and down to maximize distant speech without smearing "plosive" sounds, and you can't do it well with the limited digital sampling rates available in most low power A-D conversion systems.
Of course, there is a solution to this. Simply amplify the analog signal and clip it when it's too loud. Keep the digital systems out of it, their 1-bit minimum signals throw out low level signals that matter for low frequency sounds. This approach was documented by Robert Licklider in the early 1960's. But it's not amenable to digital processing because A-D conversion throws out all the low level signals and the zero-crossing analog data that contains the actual information. And it's got prior art, over 50 years old, so there are no patents available. So instead we get these sucky, smeared A-D based overprocessed gain systems that have already thrown out most of the important information.
