Valve’s Lighthouse as USB: Anything More than a Bunch of Spin?
This is the third article in a series on the Valve/HTC Vive Ecosystem. If you you need additional context, please begin with the first article in the series.
Introduction
A famous quote from Gabe Newell is about a lesson that Valve learned early-on when dealing with the Internet. You can find it in Episode 306 of the Nerdist Podcast at 00:12:14.
Don’t ever, ever try to lie to the Internet because they will catch you. They will deconstruct your spin. The will remember everything you ever say for eternity. -Gabe Newell
At this year’s Game Developers Conference where Valve announced their Virtual Reality partnership with HTC, and at that time, Gabe made an incredible claim about the Lighthouse tracking technology:
So we’re gonna just give that away. What we want is for that to be like USB. It’s not some special secret sauce. It’s like everybody in the PC community will benefit if there’s this useful technology out there. -Gabe Newell (Valve)
The story which accompanies the interview describes Lighthouse as a way of providing infinite input solutions into Virtual Reality. “As long as tracking is there, anything can be brought into VR, like how USB ports enable you to plug (virtually) anything into your computer.”
What the Technology Brings
In the previous two articles, we’ve dug into the technology itself, and it supports what we’ve been told. Spend perhaps $100-150 for two of Valve’s Lighthouse units and mount them in opposite corners of the room. At that point, you can almost forget about them. But any enabled device that you bring into the room can take advantage of:
- Rock-solid positional data with high precision and resolution
- Rock-solid orientation data with high precision and resolution
- Very low additional power use (passive sensors, undemanding electronics)
The Future of Vehicular Safety Communications Systems
This article is going to stray a little off-topic. Before the end, I’m going to bring it back to the topic of augmented reality and virtual reality. I hope you find it interesting.
As mentioned in my previous article, I’m taking some graduate level computer security courses as part of my continuing education. Right now, I’m taking a quick break from my project which investigates security vulnerabilities in next generation vehicular safety systems. These systems, under development today, have been given the green light by the National Highway Traffic Safety Administration.
If things go as plan, your vehicle will send and receive reports on position, speed, heading (and more) to surrounding vehicles. The road may transmit information to you such as posted warning signs (curve ahead), weather conditions, or upcoming road hazards. Read More…
