I know.


I think "double tap and hold + linear gesture" is superior to the current spiral model.

The x-axis should be used for going back/forward in the browser.
Or user configurable. But yeah, back/forward would be the common choice.

He is not referring to n900:

what i dont get is this:
how come that app worked multitouch on 5800 and not n900
arent both the screens?

The same game design would work on the N900. The video makes clear that the on-screen controls have been arranged in such a way that it's always a straight forward task to identify which two controls must be the ones currently being pressed.

Again, it's a technique that does work, but one that is restricted by many limitations. For a game with limited controls such as the one in the video, pseudo-multitouch on a resistive screen can be used. That doesn't mean the technique can work for general, system-wide gestures as on a multitouch capacitive (or true multitouch resistive) device.

For me it woudn't.

It really doesn't matter that people would need to learn constraints in order to use the feature, after all, we are n900 users. We can't say that we are willing to put up with the limitations of the device because we like its hackerish qualities and then reject ideas because they are too hacky.

We are here to have fun with it.

My point exactly!!
come on guys, you never know how much you can advance until you Make it. people can dish in ideas to cover up the limitations!!

Based on the limitations discussed above, there would be quite a few conventions that the user has to understand and follow...

1. You can't tap the screen together with both fingers. There has to be a clear leading finger (A), followed by the other point (C).
2. You can't move the leading finger while doing the gestures.
3. After the following the restrictions, you're only getting variable zoom.
4. Rotation is possible, as long as you move (C) a litlte before doing the rotating motion. Which in itself is a weird and bothersome rule. And after that it still wouldn't be intuitive because the axis of your rotation will always be (A), which is most likely the user's thumb and positioned off-center from the intended axis.

The scheme is too complex and convoluted, I'm not seeing anything worthwhile out of it.
ans 1) im pritty sure most of us cant really make our fingers touch the screen at the EXACT same time, unless we try really hard atleast. plus its not such a bad thing about one finger being the clear leader.i really dont mind.

ans 2) you can either move the leading finger or the other finger. We can make the phone just recognize ONE finger movement. (i e (A) or (C).) And change gestures accordingly. or if you REALLY want both A and C to be recognized..then you can adapt the gestures according to point (B). ( the center point if you remember.)
the angle of that can be directly attached for rotation etc.

ans 3)come on man, this is just an idea..BABY steps :P

ans4) i think i fixed that in answer 2.

but correct me if Im wrong.
im just dishing out ideas to fix the problem.

im pritty sure this is quite possible.
and i would love if you could tell us more cons..
we do not know exactly how resistive touch works either.
BTW, did u know our screens are pressure sensitive?
sooo..light touch = rotate and normal touch = zoom?
hey im just saying ! :P

#2 once both fingers are in contact with the screen, the screen only knows of the single point (I assume right between the fingers). If you move both fingers apart at the same pace and distance, I assume the derived point does not move. And in this state, if you rotate your fingers in that exact same axis, the point doesn't move either.

See what I'm getting at? It throws away all the advantage of multitouch. (3) If you want to emulate the gesture, it comes with all this baggage (restrictions) and all you're getting is just the gesture... (thus my double tap-hold suggestion, which I think is superior for non multitouch implementation)

ps: the screen will not know which finger you're moving, once both fingers are in touch with the screen. Thus the rules I've written.

#4 See point #2 above.

Making use of pressure sensitivity (Yeah, I know it's there on my N800 too) is interesting, but I don't think it's intuitive and prone to mistakes.

What's wrong with this ysss?

I'd be perfectly happy with only moving one finger if it meant we could use multitouch gestures in UIs.

Beside all the cons already mentioned in the thread? Nothing I guess

Just that the UI instruction will come with a few simple rules:

1. You must start the multitouch gesture one finger at a time.
2. The first one to touch the screen must not be moved.

Hmm OR.. to make it even simpler, maybe we can assume that the thumb will always be on the bottom; so the rule can be simpler if this can be guaranteed:

1. You must not move the thumb.
