    With reaction time for triggering a predetermined behavior (clicking a button, starting to run, catching a falling object, etc) in response to a predetermined stimulus, latency will be lowest with tactile stimulus.

    I meant extending vision into UV/IR, or just improving color vision.

    Pupil size adjustment acts like "dynamic contrast" on LCDs, it's not real dynamic range, and it's definitely too slow. Right now imitating the eye with a camera aperture is probably the best option, but maybe in the future something like Ferro Liquid Display could give completely dazzle free dynamic range adjustment with no mechanical parts.

    The brain can adapt for better signal selection with enough training. Play some Battle Garegga until the "invisible bullets" stop being a problem for a demonstration. Additionally, brain power would be freed up by not having to compensate for all the retinal blood vessels and the blind spot obscuring our vision.

    Tactile reaction time is faster than visual reaction time. If the resolution is high enough and the switching time fast enough, could this system be advantageous where fast reactions are needed (eg. games, sport, driving, combat, etc.). Could it be combined with normal vision for a kind of minor precognition?

    How about using it for extended vision with more frequency channels, wider or narrower field of vision, faster automatic brightness control, etc? Touch has multiple channels but how many are high enough resolution to be useful?

    As anyone who's used psychedelic drugs will know, the human visual system is bottlenecked by the eyes. The brain can certainly handle more powerful sensors so we should be working on making them.

    No, it's not. Scoring the headshot requires prediction and deception of your opponent as well as timing. Rhythm games only require timing. Rhythm games have zero tactical depth, so they shouldn't really be called games. They have even less depth than tricks like juggling or riding a unicycle, which at least require real time decision making because they involve unstable systems. Guitar Hero is a perfectly stable system, and you can get a perfect score with no thought at all. The only rhythm game with any value is DDR double (8 switch) mode, played without the bar (or other similar games). Here the unstable system is your own body. In Guitar System you are only making minor hand movements so momentum and balance are not an issue.

    I faced the public school system (state school system in UK terminology), which is boot camp on easy mode, so I'm certain that if I ever somehow ended up in real boot camp it would be a corpse producing situation.

    Ok, so what does "civilized justice" even mean, and how would you have used it to defeat Nazi Germany, Imperial Japan and North Korea?

    "Civilized justice" means the civilian legal system with all its checks and balances.

    No, I'm pretty sure instructors are bound by laws and regulations.

    But those laws and regulations allow for conscription and infliction of immense psychological harm on innocent victims (although not in my country). Military people often claim it's not like that anymore, but every military person has strong incentive to lie about it (as each new recruit lowers their chance of death), and I've read many reports that "sock parties" and the like are still standard practice.

    And?

    Therefore a drill instructor is morally equivalent to a terrorist. Torturing recruits is not necessary for a functional armed forces. You could just as easily prepare recruits by a program of gradual desensitization, eg. having them attack cardboard cutouts, then realistic 3D dummies, then live animals, then realistic animatronic dummies. This could be combined with biofeedback training to train reduced stress response. A similar program could be used for reducing stress response to danger. Typical "boot camp" scenario is such that suicide is indeed the logical response for anybody not of the bullying personality, and in that case it seems sensible to take any action that would reduce the chances of others having to suffer in the same way.

    Or possibly several corpses. The military is based on the principle that some evil people are beyond the reach of civilized justice so the morally correct thing to do is to kill them. In boot camp, you're faced with an abusive psychopath who also happens to be beyond the reach of civilized justice. He probably believes what he is doing is right, but then so do the "enemy combatants". By any logical standpoint, the fat guy in Full Metal Jacket was the real hero.

    Nothing to do with flicker irritating the eye, it's true of both CRTs and LCDs. 60Hz is not fast enough to give perfect mouse control. You can easily tell the difference if you compare a 60Hz display with a true 120Hz display side by side.

    Faster frame rate also reduces latency by decreasing the frame transmission time, and many other delays are an integer multiple of the frame time so they're improved too.

  22. Re:Is it time yet... on DARPA Builds Smarter Version of Microsoft's Clippy · · Score: 2, Interesting

    This is true, and it's the reason why low interface latency is so important. No real world hand tool acts with a delay, especially not with an inconsistent delay. Every time there's a perceptible delay in the interface it breaks the fast brain link.

    This is one reason why 60Hz refresh displays are unacceptable even for general desktop use. A faster display gives you a tighter feedback loop, making it easier to perceive the computer as part of your own body. This is very noticeable with mouse control, and I suspect most people who complain about the inadequacies of mouse control have never used a mouse with both fast input and fast output sampling rates. It's also the reason why any kind of graphics buffering to trade latency for throughput or image quality is unacceptable.

    A good interface isn't something you see, it's the feeling of transparency.

    Smart interfaces are a bad idea, because you can never be sure how they will respond. Dumb interfaces are predictable tools so they require less brain power to use than the two-way dialog of smart interfaces. With dumb interfaces I can fire off a long string of commands without having to stop and think between each one. This improves productivity more than any supposedly intelligent interface will.
