You remember that person you danced with and thought was wonderful, and then you met them the next day and your opinion was less favorable? That’s what people call beer goggles. Alcohol impairs judgment. It makes people chattier and improves their self confidence, but also makes them think others are more physically attractive and more interesting too. That’s why people get drunk apparently, because it upgrades otherwise dull people into tolerable company, breaking the ice and making people sociable and fun.
Augmented reality visors could double as alcohol-free beer goggles. When you look at someone while wearing the visor, you wouldn’t have to see them warts and all. You could filter the warts. You could overlay their face with an upgraded version, or indeed replace it with someone else’s face. They wouldn’t even have to know.
The arms of the visor could house circuits to generate high intensity oscillating magnetic fields – trans-cranial magnetic stimulation. This has been demonstrated as a means of temporarily switching off certain areas of the brain, or at least reducing their effects. Among areas concerned are those involved in inhibitions. Alcohol does that normally, but you can’t drink tonight, so your visor can achieve the same effect for you.
So the nominated driver could be more included in drunken behavior on nights out. The visor could make people more attractive and reduce your inhibitions, basically replicating at least some of what alcohol does. I am not suggesting for a second that this is a good thing, only that it is technologically feasible. At least the wearer can set alerts so that they don’t declare their undying love to someone without at least being warned of the reality first.
