questions like “Who was I discussing the facial recognition system with last week? ” and the system would offer a list of possible matches. I can replay the conversations in a picture-in-picture type display whilst continuing a conversation with someone else.’
Chris walked back to the desk and picked up the three pairs of glasses. They looked like ordinary glasses, two with clear lenses and one with dark lenses like sunglasses. ‘I suppose you’d like to have a play?’ he said. He handed the glasses to his guests and they put them on. Maynard spent some time examining the frame first.
‘I’ve read the specifications,’ said Maynard, ‘but I can’t see how you can fit so much into these frames. You’ve done a remarkable job. They look to be completely sealed, how do you charge them?’
‘You’re right,’ said Chris. ‘They’re totally waterproof, and weigh only slightly more than a regular pair of glasses. The camera lenses are almost undetectable except under bright light. To answer your question, they use inductive charging. I place them on this surface here and an induction coil creates an alternating electromagnetic field which is converted to an electric current by a second coil in the headset. I’ve made some refinements to reduce the heating effect and energy loss, but basically it works like your electric toothbrush.’
Joshua had already put his glasses on and he was waving his hand in front of his face.
‘What kind of coverage are you getting?’ said Maynard.
‘Do you mean how far can we stray from the campus?’ asked Chris, Maynard nodded. ‘The glasses transmit to a repeater that is about the size of a cell phone.’ Chris held up his phone and it looked quite unremarkable. ‘It uses technology similar to Bluetooth, although I’ve made some modifications to that too, I got rid of the lag, upped the speed and made it less power hungry. The repeater can transmit to base stations within the tolerances of a usual cellular network, say one mile in the city, about twenty miles in the open. It depends on a lot of factors: interference, obstacles, that kind of thing. In fact, this system now piggybacks the existing infrastructure using regular 3G and 4G networks where available. I use multiple antennas to increase the bandwidth.’
Joshua looked to Maynard who was nodding approvingly and examining the repeater. Joshua was looking confused. ‘Sorry,’ said Chris, ‘by bandwidth, I mean the amount of data I can transmit in a given period of time.’
Joshua waved the explanation away. ‘Don’t try to explain these things to me Chris,’ he said. ‘That’s why I brought Maynard with me. Why don’t I go and fetch coffees?’
‘Great,’ said Chris, ‘you can do some field testing for me on your way.’ He sat at a computer terminal and tapped a few keys.
Joshua stopped and held his hands out in front of him. ‘Er, Chris,’ he said. ‘I’ve got a problem, my headset has gone blank. I can’t see a thing.’
‘I know,’ said Chris. ‘I’d like you to try out something I think has real commercial potential. I call it blind-man mode . The computer system will guide you to your destination. I’ve told it you want to go to the cafeteria, just follow the instructions you hear and you should get there in one piece.’
Joshua set off slowly towards the doorway, his hands held in front of him.
‘Have faith,’ said Chris. ‘I won’t let you walk into any walls.’
He turned to Maynard and said, ‘The technology is a little overwhelming, but you’re going to love the experience.’ He carried on explaining about data transmission rates, error correction, cell-shifting, and anything else he could think of. He didn’t pull any punches but Maynard seemed to take it all in his stride. What did he expect from an ex-NSA and MIT graduate? After twenty minutes of answering deep and probing questions, Joshua returned with three Styrofoam cups and a gait that suggested he had made it
