The mind-reading cycle helmet - does it get a green light from you, or a red flag?

I'll wear one - if all cars are fitted with them and if my red lights are arranged to spell F*~# OFF

Wire it into a cutout circuit in a cars ignition system and we'll talk.

I would only be interested if it fired rear-facing weapons when you thought in Russian.

Will driverless cars be able to see the flashing lights?

To be fair, she isn't studying engineering...

What colour does it show to indicate extreme anger, verging on genocidal hatred of motorists?

I think the little book of calm should be on my Christmas list.

Years ago I read a not very good Sci Fi story in which news laws were introduced, requiring people to have indicators installed on their foreheads. The first was a mood indicator, which glowed if someone was attracted to someone else they were speaking to. The other glowed if the person lied.

There was some sort of political point being made rather clumsily by the writer. It wasn't a great book and I only read it because there was nothing else to hand to read at the time.

I spent years growing up learning through many a hard lesson the need to and how to hide my thoughts and feelings from all but those I trusted, now you want me to advertise them to any passing person. So from now on I'm going to have to learn how to fool a helmet as well? Although I suspect that even if I was to wear such a thing it would persistently flush amber for constantly confused.

More seriously, it is stretching the innovative imagination beyond it's limits to think that this is a practical and helpful. For a start are thoughts, feelings and mood really so singular and linear?

Interesting technology, duff application.

Surely the most obviously useful application in this space would be to have a motor vehicle detect a driver in a non-alert state or who has had a sudden rise in alertness (eg looking up after fishing for a CD to realise that they're heading towards something) and sound some sort of horn - ideally different from the manually activated one - to warn other road users in the vicinity that there's a muppet falling asleep and heading towards them. Add flashing lights for easy identification in heavy traffic.

Basically it looks like they've had to work from an EEG which is physically in contact with the head and thought "who wears a helmet?" rather than think about how the technology could actually solve a problem (rather than create one). This is just existing technology in a plastic cover, it's not a progressive prototype of thinking the technology into a future application where a non-contact EEG could provide real benefit.

When I was doing my engineering masters on any project like this we'd be expected to identify a market need and this doesn't seem to have any market whatsoever. Completely pointless, I'm out!

Ok, we know what it does. But what's it for?

I don't really see the point. If a motorists gives a cyclist 3 feet then everything is fine; less and it could cause an accident. That is pretty simple yet appears to confuse car drivers just think what would happen if cyclists attempted to educate them on the meaning of the flashing lights on a helmet.

Very Quaint - what we really need is for Arlene Ducaoto to design a car that converts poor driver eye road scanning behaviour into automatic speed limitation - the more aggressive, scatter brained or distracted the driver the slower the vehicles maximum speed and acceleration rate becomes - Simples!

"Let’s imagine it did become widely used among cyclists, and motorists were aware of how it worked – it’s sadly not too much of a stretch to think that some drivers, seeing the green lights lit up, might see how quickly they could get them to turn through solid red to flashing red."

My thoughts exactly. Cupid stunts would see this as a game.

"With our thinking caps on, we can see it having more of an application among the military or emergency services – imagine a police commander in a riot control situation, able to pinpoint where his officers on the front line are under most stress."

Again, rioters would simply concentrate on the flashing red helmets.

At the same time, when a large vehicle is just inches from your back wheel, wouldn’t it be good to have a way of letting the driver know just how you feel about the situation?

I would have thought a being able to activate a very bright rear light angled up towards driver height would be more effective.

I'm out.
