Google Glass - the next step - where sensory integration goes next?

Google Glass

As this sort of wearable computing takes off, it's likely that hearing systems will become and integrated part of the wearable computer.

All we need to see is a receiver wire port on the underneath of that Google Glass arm and your hearing system becomes integrated with your mobile computing and comms. There's already a mic system built in and the front of the frame will allow a decent mic array to beam-form at full head-width away from obstruction.

The fact that Google is putting it's name on the hardware is great as it means the output is likely to be largely open source which allows anybody to develop it. The blurring of the line between comms/computing and hearing aids is going to cause the FDA and the hearing aid manufacturers a few problems too.

Loud noises compared......


A great comparison of the loudest sounds on earth.

I wonder how these compare with the Russian Meteor explosion today.

Apologies for the swearing if you speak Russian.

Video - Sonic boom at 27 secs.

New BAA impression taking guidelines.


Personally I'm not keen on the bracing hand position used in the gun technique as it won't prevent the tip being pushed forward if the trigger 'jogs' on the ratchet mechanism. The problem is that the bracing hand sits against the fist of the trigger hand - exacerbating the issue while not preventing the force from the palm of the trigger hand pushing the gun forward as the unloaded/skipping trigger collapses backwards.

I can't see why clamping the actual nozzle between thumb and forefinger while using either the back or front of the hand and remaining fingers to support and steer the nozzle isn't preferable.
