At the same time, when combined with even small amounts of alcohol there is a significant impairment. Further, the test isn't really testing reaction times that are relevant in realistic driving situations. The issue with cannabis impairment is delayed reaction to surprising stimuli. So, for example, the kid chasing his ball into the street. Nobody would expect significant motor impairment.

At about 17 seconds you can see the elephant lifting the croc out of the water, presumably with his tusk. I'm guessing that smarted, but you're right, it isn't entirely clear.

Smells like Grace Hopper.

It's time to get the funky bunch back together.

Not to be a cynic, but they all seem like actors.

Yup. People that don't graduate high school often surround themselves with people that will believe whatever the fuck. Your point marker guy?

If it's that hard for pedestrians to see the car, how hard is it for the car to see pedestrians?

I don't like soccer because it's boring. The diving just makes it pitiful too. Sprinkle in a dash of settling games with penalty shootouts to really bring out that cheesy flavor.

I agree with you in general. I think it will be a successful product potentially. I just think people are going to find themselves disappointed given all the hype. I just don't think the technology is satisfactory even on the cutting edge. It would be like all (even the best) portable mp3 players sounded like finger nails on chalk boards. Apple came along and made an affordable "finger nails on chalk board sounding portable mp3 player" and we all expected everyone was going to be jumping to buy one rather than simply continuing to listen to their nice home stereo instead.

Just as a first order critique. Do you really think gamers are going to settle for 640x800 screens that subtend even wider visual angles? With 800 pixels over 90 degrees you're talking about a nyquist frequency of 5ish cycles per degree. That ain't exactly a retina display. That's like a tenth the resolution of a retina display on a linear dimension, or one one-hundredth the number of total pixels.

I think this thing will have a highly anticipated launch and peter out as people find themselves preferring to game with their traditional interfaces instead.

Sorry, I was referring to the latency papers that @ChaosEngine posted. He mentions that their head-tracking sensor is capable of 2ms samples. That is indeed impressive for consumer level tracking. However he goes on to say that they use this "density of samples" to integrate a more accurate measure of position. In other words, they average over multiple temporal samples in order to achieve a more accurate spatial measure. However, if you do that, the samples you are using to produce a head position instantaneously is at least partially influenced by spatial information collected more than 2ms ago. When you do this too much you'll get sluggish head tracking which lags the head, and can often make people sick. However so can the alternative of low-latency though spatially noisy head tracking. That will just look jerky and spastic instead of sluggish. It's a balance, but his suggestion that they chose to average suggests that they needed to due to noise in their custom sensor. I have no doubt these guys have done a better job than previous attempts at low cost HMD systems. I just don't think they've done anything ground breaking, and even the cutting-edge technology I find unsatisfying.

Honestly, I'm pessimistic. I work with Virtual Reality for a living and I find head mount displays (even premiere research quality head mounts with top notch head/body tracking) to be a shitty experience. I'd rather nvidia glasses done well. My main complaint is with the very short optical distance between your eyes and the display.

Even with the latency thing, he kind of sets up and breaks down his own argument. He says, 2ms samples, so latency should be great! Then he says that they integrate over those samples to get an accurate measure... well... there goes your low latency.

I love precision machining. Huge up vote.

How do they get the zamboni out there?

Dude, you aren't supposed to use your hands.

Are you implying I drive a Harley? Otherwise I'd prefer you call me queer, son. Virginia Tech was the most deadly shooting in US history. He used pistols with standard clip sizes. There are also these things called bombs, should we ban fertilizer?

Please define tragedy. Statistically speaking, tragedies of these sorts are prevented by doing absolutely nothing at all. Statistically speaking... they don't happen. It's a couple of sad things that happened and everything, but it doesn't compare to actual problems, you know... like accidents.
