    They say "It makes gaming better." But how would that work?

    It opens up options for future games.

    Think of it like the Wii Motion Plus and what that accessory adds to the Wii.

    A gyroscope gives greater accuracy than an accelerometer.

    Basically we're looking at a Nintendo Wii controller with a touchscreen.

    So the gyroscope covers pitch, roll, and yaw. The accelerometer covers vertical and horizontal movement.

    Correct?

    Yes and no. The accelerometers cover "tilt." Together you get the ultimate controller.

    No thats not how it works, its like this. First you are gaming, then you go to the local Greek deli and get a Gyro then you go back to gaming only now that you have a Gyro its way better. Duh:rolleyes:

    You get more sensors of motion. In other words, the iPhone will know the nature of your/its movements.

    I'm having a hard time wrapping my hand around the differences between the gyroscope and the accelerometer. I've used a lot of games and applications that use the accelerometer and I can't think of a limitation of the accelerometer that would be remedied by a gyroscope.

    Does the gyroscope measure forward, backward, and sideways movements? While the accelerometer only measures tilt?

    So apple is really is focused in turning this into more of a gaming platform then.

    Think of it this way:

    Accelerometers only:

    aircraft game: (coming in for landing)
    To turn left you just tilt the device. The program will then manipulate controls in game for rudder and ailerons(left/right tilt of AC).

    Gyrp and Accelerometers:
    same game: (coming in for landing)
    You control the rudder by rotating the device on the x-axis. i.e. imagine the device sitting on it's side in landscape on a table, the table represents the x-axis. You simply rotate it to control your rudder. You can then tilt the device to add tilt to your wings to have greater control over your flight direction.

    Not so much, think of the virtual apps that could benefit from finer movement controls, more so than just the accelerometers or the compass. To start out with you will see games taking advantage of this tech, yes! Others will follow with non-games that take advantage of gyros.

    It's going to be AWESOME for pilots as a backup attitude indicator/EFIS display. For reference, the FAA approved, all singing all dancing version of the iPhone's sensor package (called an ADHARS in aviation speak) costs somewhere between $10-250K. The $10K end of it is by recent upstarts who are "shaking things up" in aviation (Aspen Avionics). This will of course not compete with certified panel mount avionics but a $200 phone with a $100 program in your pocket that backs up your $100K avionics is a pretty sweet deal for any pilot. I can't wait to get mine.

    A gyro?

    So...there's going to be a motor constantly running inside this thing?

    At least, that's how I remember it working on that old V2 we pulled apart to reverse engineer.

    Anybody care to explain specifically how this gyroscope functions?

    Also, it offers a MAJOR advantage over the accelerometer! It works in zero gravity!!

    It's not really a mechanical gyro. Solid state electronics have supplanted the mechanical gyros of yesteryear (not an unusual evolution). But the term gyro is still used to describe today's modern, no moving parts, angular accelerometers.

    The advantages are much smaller, much more reliable (fewer moving parts), much smaller and no precession - a winner all around. But traditionally this hardware has been expensive and has used complex laser courses, to get it down to consumer grade pricing as a secondary function to a PHONE is amazing!

    It was worth it to prove that you did NOT, in fact, ignore me as you said you had.

    I guess I just have a little too much respect for people, as I'm always curious what they have to say. At least I'm not delusional enough to believe there would be a motor spinning in my iPhone. :p

    However, I do regret reading anything you post, so hopefully this will be the last time I do.

    Too much respect to ignore somebody, but not enough to not say "hey, I'm ignoring you, ******."

    XD

    Oh, and if you took that part of the post seriously, then ask for pics of the V2 while you're at it.

    So they brought up the Gyro*....:cool:
