Google promises that Glass, its new augmented reality eyepiece, will open up a new world of hands-free computing — a way to search, translate, record video, and take photographs without having to press buttons or rummage through pockets to retrieve a smartphone or tablet.

There are lots of potential applications. To start things off, Google lists cooking, cycling, skiing, golf, and firefighting — physical activities where holding a device is impractical if not impossible. But really, it was only a matter of time before people began using it for sex.

The first attempt, an app called Tits and Glass, allowed Glass users to stream pornographic images to their headset. The app was promptly banned from Google's app store, but was recently reinstated.

Now a new app for Glass developed by Lebanese product design student Sherif Maktabi and called Sex with Google Glass lets couples use the wearable technology to record their intimate activities, and — if both partners are wearing a headset — even see sex through their partner's eyes by streaming the view from their respective devices.

The app is controlled through groan-worthy voice commands. For example, saying "Ok Glass, it's time" begins the recording process. Once sex is over, recording is ended by the voice command "Ok Glass, pull out." Video can be replayed for up to five hours before being automatically deleted from the app.

Frankly, I think the idea of having sex while watching a stream from the perspective of your partner sounds narcissistic at best, and mildly disturbing at worst, so I highly doubt that this feature will become immensely popular. And putting a barrier of technology between partners may prove a turnoff and intimacy killer for many.

But Glass as a tool to easily record or stream homemade porn? There is probably a big market for this kind of thing.

Concerns about morals or privacy aside, it's important to remember that porn is a big driver of technology adoption. The adult film industry has been at the forefront of technology for years, at least since it picked VHS over Betamax. Technological innovations pioneered by the porn industry include online payment systems, streaming video and video chat, DVD, and HD video formats.

It's hard to say at this point if augmented reality computing will usurp smartphones, tablets, and laptops, or if it will remain a niche activity. But if augmented reality computing like Google Glass is really going to take off and become a market leader, it should be expected that sex and porn will be a key driver of adoption. The fact that some people are already using Google Glass for sex paints a rosy picture for the technology in the longer term.
