hayesk said:Just touching it is not tactile feedback. That would be like saying a piece of paper provides feedback if you touch it. Feedback means a signal is sent back to the user to acknowledge the the pressing of the control. The 3G iPod buttons gave an audio click - that is aural feedback. They also showed things on the screen - that is visual feedback. But they didn't spring, or have a physical barrier that you push through, so there was no tactile feedback (i.e. nothing that can be physically felt) to let you know that you pressed the button.
tactile |?taktl; ?tak?t?l|
adjective
of or connected with the sense of touch
perceptible by touch or apparently so; tangible
designed to be perceived by touch
Tactile means that you touch it! If you touch something you get a tactile feedback from it, unless your finger is numb. Thus, if you're waving you hand over control, you get no tactile feedback. Whereas, even if the control doesn't push in, the simple act of touching a control does give tactile feedback. (Perhaps less tactile feedback than a control that does push in, but it still gives tactile feedback.)
hayesk said:When you press a button on a dead iPod, it does nothing, and it feels exactly the same as pressing a button on a working iPod - no tactile feedback.
Irrelevant. If you push a key on the keyboard of a dead computer it behaves the same as pressing the key on the keyboard of a working computer. So, by your logic, these keys that press down give no tactile feedback.
hayesk said:Who said it was revolutionary? And it could consitute a none-touch interface. It depends on if the patent is describing the control or the entire iPod. If there is a cover, you are not touching the control (the screen underneath), but the cover over it - hence none-touch.
My point was not to say that your suggestion was not possible, just that it was a small step above what already exists, as opposed to a revolutionary leap forward based on the description in the patent. Of course, for anyone who knows a little bit about patent writing and patent law, what's written in the patent is probably the broadest possible applications that Apple can think of to include in their patent.
hayesk said:A better (i.e. more scratch-proof) cover would be better. Who cares about fingerprints? You can clean those off. I don't want to hover my finger over something to control it - I'd always have to be careful not to touch the screen (unless it was durable). Not very good when on a bus, train etc., where the vehicle is shaking.
And if a better material were easily available, don't you think they'd be using it?
