    FK braintrust help...(accelerometers)

    Im in need of the collective brain trust here at FK..

    Im looking for toys/products...etc that made use of an accelerometer.. PRE-1999

    If you dont know what an accelerometer is.. its a chip that uses voltage/gravity to detect the force/angle/speed/motion of itself..

    the Wii makes use an accelerometer in fact..

    anything you got..thanks

    is that the Nintendo powerglove?

    just looking for the right stuff to google, since no linky!

    BAH... debunked:

    the Power Glove did not use accelerometers. It used ultrasound to triangulate the position of the glove relative to the tv. Two ultrasound transmitters in the glove communicated with 2 sensors in an "L-bar" on top of the TV to locate the glove in 3D space

    I'd almost swear that the Sega VR headset - never produced - did. It was around '93 or so.

    Having the accelerometer chip pre-1999?
    Maybe some trowing your laptop away and hope that the hardrive locks before it hits the grown type of game?

    Maybe small controlled airplanes had accelerometer for better handling?

    The Slam Man might have one, but I'm not sure if it's pre-1999. Sporting equipment is your best bet. Like punching bags, etc.

    A lot of the toys that you think use an accelerometer are nothing more that a steel ball that moves inside a box with contacts on the side opposite of the desired direction (that or a hinged contact). So, it's just a momentary switch that gives no real information other than "on" or "off." A good example is some earlier video game fishing rods.

    Actually, some electronic handheld fishing games might contain an accelerometer for accuracy.

    There is a mention of the Sega fishing controller using an accelerometer here...

    I opened my Sega controller up and there's something rattling around, so I don't think it's the really accurate spring type (just the contact type I mentioned above).

    If you don't mind me asking, are you looking for an accelerometer for a specific application project or just doing general research on them? In either case, I can take a picture of it if you need it. I'll try to check it with a meter to see if it is indeed just a contact switch.

    I doubt the MEMS technology required for modern accelerometers were cheap enough to be integrated into games in the 90's. It's only recently that the manufacturing process has become widespread and easy enough for the prices to drop. I can't seem to find any data to back this up though. Also, if you just need to measure if something is stationary or not, a metal spring inside a metal cylinder could be enough, and would be cheap enough to mass produce. But this wouldn't allow wii-like control.
