Gyroscope Gives CellPhones 'Tilt Control' 213

Paul Stamatiou writes "You can now control cellphone activities by simply tilting it. "If you have a game involving keeping a car on the road, you do that by tilting," says company spokesman Jan Ahrenbring. The tilting technique can also be used to sweep large virtual pages across the phone's screen, which acts as window on the information."

    How about 3 day battery life with 6 hours talk time?

    How about good, clear calls?

    How about not magically losing signal when I walk in to another room?

    • Perhaps you're living in the wrong country. My Nokia GSM has more than 6 hours' talk time, the battery runs for ten days or so, and reception is crystal clear everywhere I go.

      All it is really missing is motion control. That way I can answer the phone simply by picking it up, hold a call by putting the phone down, and scroll through my address list by shaking the phone like a lunatic instead of clicking those damn arrow keys.

      My guess is: if the rocker control is cheap and easy to hook up to the UI, it will be a natural and useful extension to the way we use phones.

          For some reason you Americans (though eminently logical in most areas) persist in believing that you live in a free market. A free market is one where government does not choose the winners but defines the rules and allows any player to compete. The USA just does not work like this: most significant industries are incredibly regulated, and telecoms is one of these. Energy is another.
          The USA's "free market" is anything but. For a really free market in telecoms, you have to look to countries where there is no anti-competitive parastate monopoly.

            2. is it reasonably reliable?

        • The batteries are generally the same for the equivalent US and GSM models of phones. The main difference is the amount of power the radio takes.
          • Straight GSM doesn't use much power. Maybe that's related to the population density argument that Rasta Prefect brings up, or that the radio parameters were designed for it, and some of it is the protocol design for keeping track of where users are.

    the technology used in this case might be more advanced (gyroscope), but the idea of tilting the phone to activate a function or control something isn't new. i had a casio watch many years back that would automatically turn on the backlight for a few seconds if you lifted up your wrist to look at it. i'm not sure this is a good thing though...just one more thing to keep drivers who shouldn't be on the road in the first place distracted.
    • Old stuff indeed, the Microsoft Freestyle Pro gamepad is five years old and has a very similar feature, but instead of a gyro, it uses an acceleration sensor (ADXL202) to sense the angle of the controller relative to the earth's gravitational field. A gyro is actually not a good idea for this kind of control because it can only sense relative rotation angles (i.e. you have no zero point).
    • I've never seen that. Wouldn't the sensor turn on the backlight during the day too? Also, wouldn't it randomly turn it on as you moved around? I would think that such a feature would run the battery down pretty quickly.

    Is is only me, but I'm surpised every time some company comes up with some new feature for a cellphone, and they demonstrate it by saying it might come in handy when playing a game? Every new phone is marketeered by saying how much games it has, how much ringtones, how easily you can change the cover,...

    I can't think of a good thing I can do with a phone with a gyroscope in it right now. I assume that anyone can come up with some basic telephone feature that is still missing. One I can come up with is "if busy, present a callback function (Call back in 30 seconds? Yes/No)". Another one is "answer and delete message".

    Oh boy, if only I would design phones...
    • "if busy, present a callback function (Call back in 30 seconds? Yes/No)"

      Don't most phones already do this? My old Ericsson did it automatically, and on a Nokia I think it's under Call settings - Automatic redial

    • The "callback" you refer to is present on any Ericsson phone i've had. When the phone is busy it asks you "User busy. Retry?" and keeps on retrying until it gets a normal signal. It then rings to notify you that a call is being made..

      As for the Gyro.. well it would make a nice McGyver episode, where McGyver uses the cellphone's gyroscope to navigate a broken airplane thus saving hundreds of lives...

    They keep trying to use this "tilt" technology somewhere. I first saw it at PC Expo several years ago (but before it became "techxNY" or whatever) - It was a SD card add on for a palm V. They were making a big deal out of scrolling maps with it. I demoed it, and tried to be polite about it, but the fact is that it is useless.

    There is much less control in tilting a palm while trying to watch the screen scroll, and then tilting it to level again to read the map - and once you tilt it level, you have to switch the toggle to stop it scrolling if you tilt it up to look at it.

    It reminds me of those games where you have a marble and have to make it fall in the hole in the middle of a big plate - you always overshoot the hole and end up on the other end.

    It's a dumb way to solve a problem that has already been solved via scroll bars and/or buttons.

      Seriously, I don't see why they suggested the car driving game - the marble game simulator is clearly a better example.

        Well done. Course, at least in the real world marble game you can see the ball and the hole at the same time. In the Cell Phone virtual one, you can use the large "virtual screen" to see a high resolution recreation of the play area... the fact that you dont know where the hole is half the time only adds to the challenge. :)
    • Microsoft did this years ago with the Sidewinder Freestyle Gamepad. They bundled it with Motocross Madness, probably because it was the only game that played decently with a tilt controller.

    Could this perhaps be used as a pseudo GPS system? Rather than determining your position by a GPS signal, could have data on gradients of an area and have the PDA in your car in some sort of cradle to hold it flat. Then the PDA would detect when you were going up a hill (the software would have to discount speed bumps) and update your shown position. Provided you kept to the roads, by checking your car's angle it could determine your exact position, at worst it could be used to show were on a contour map you were.
