<div>Hello everyone I would just like to start off by saying I have enjoyed very much the conversations that go on inside this mailing list. I have learned a lot more by trying to research answers and solve problems then I ever thought I would. With that being said I have been thinking about multi-touch lately and after some things on the wiki page
<a href="http://wiki.openmoko.org/wiki/UI_Improvements">http://wiki.openmoko.org/wiki/UI_Improvements</a> I noticed that is mentioned the zoom feature of the iphone. it stated that</div>
<p>Question: </p><pre> What exactly does the touchscreen see when you touch the screen with 2 fingers at the same time,
when you move them, when you move only one of the 2, etc. I'm also interested in knowing how precise
the touchscreen is (ex: refresh rate, possible pressure indication, ...)?
<li>The output is the center of the bounding box of the touched area
<li>The touch point skips instantly on double touch
<li>Pressure has almost no effect on a single touch, but not so on a double touch. The relative pressures will cause a significant skewing effect towards the harder touch. You can easily move the pointer along the line between your two fingers by changing the relative pressure.
<div>So my question now is do we have access to the bounding box? If we can get at the coordinates of the bounding box can we not figure out if the bounding box is shrinking or growing? The iphone has a camera which makes the zoom feature more attractive as you can zoom in on pictures you have taken with the phone. But with the better screen resolution on the neo I would still like to be able to manipulate pictures I have on my neo. Also if we have access to the bounding box we could with some practice figure out when users are trying to rotate an image. This could also be very useful with web browsing. With the iphone you can view the entire website as if on a normal computer then zoom in of places you want to read. I think this would be a great feature on the neo. I wouldn't have the first clue how difficult that would really be as I am sure it would be quite encompassing but with the high resolution of the neo this should help a great deal. And even if we couldn't get multi touch working a zoom feature in the browser would still be helpful. You press the zoom button then click an area to enlarge. Just curious how difficult would this be? Any way I have just been kind of looking at the iphone and it doesn't seem to be very multi touch but as it has not come out I could be wrong. It seems to only be able to accept 2 simultaneous inputs. If we had access to the bounding boxes created when two fingers touch the touch screen the I believe we could simulate multi-touch. I don't know how responsive this would be to the user either maybe someone could answer that? So I am just curious if this is possible in some degree or not?
