Ultrasound is the only reason they're similar!!!!

And it's such a weak similarity it makes the remote completely trivial!

Do you know what ultrasound is? If you did, you probably wouldn't use it as the reason for why they're similar.

if you know, it was not just a small part in it's function's it was a big part. do not disreguard one of it's core part's just because hey "it only used ultrasound" like it's nothing when it used burst signal's to transmit. without doing that the powerglove would not have worked the same way.

as a matter of fact the ultrasound technology they used was a big part think about this for a sec. just like sonar or radar of a bat with sonar location.

notice:

Zimmerman built the first prototype that demonstrated finger flex measurement and hand position tracking using a pair of ultrasonic transmitters

The ultrasonic speakers take turns transmitting a short burst (a few pulses) of 40 kHz sound and the system measures the time it takes for the sound to reach the microphones. A triangulation calculation is performed to determine the X, Y, Z location of each of the two speakers, which specifies the yaw and roll of the hand. The only dimension it can't calculate is the pitch of the hand, since the hand can pitch without moving the location of the two ultrasonic speakers.

with out it certain game's would not have been able to determine certain thing's about your postion because just like a Bat used sonar to tel it certain thing's this is doing thing's like that.

like i said please do not disreguard something that's a core because you think is somehow just a trivial function

Do you even know how the remote you mentioned worked?

Let's say I have a lightbulb. When I clap, it turns on and off. Basically how that remote worked, except it used certain sounds for each button and the TV reacted accordingly.

The prototype you speak of makes short bursts of sound whenever the hand is moved (I believe). Then, according to the time the sound takes to get to the speaker, its position is calculated.

So tell me, without hiding behind big words you probably don't even know, explain how they're similar. IN YOUR OWN WORDS.
