<div dir="ltr">Darius,<br><br>You say you work with lots of groups, have you ever actually done any
coding for maemo and obtained actual coordinates of the distinct
multitouch hotspots as you touch it?<br>I would love to see examples of your code because multitouch would be a nice feature to have.<br><br>You will find I am actively involved in making the most out of these nokia devices and have investigated a great number of options and directions for the input and output side of these devices and multitouch is something I have put quite a bit of brainpower towards.<br>
<br>The effect you see when sideways scrolling is exactly what I specified in my earlier mail, but saying it is multitouch is flat out wrong, it is simply the sideeffect of changing the centre of gravity.<br><br>With a true multitouch surface the running application obtains multiple distinct hotspots, that is each finger produces its own hotspot at a specific location, the surface can track multiple hotspots. <br>
The event subsystem must be geared to handle these hotspots and the applications themselves need to know what to do with them.<br>
<br>The "multi touch" effect you are seeing is the averaging of your distinct fingertips into a single cursor location. Applications for maemo expect and obtain a single cursor location and know nothing about multiple hotspots (the touchscreen simulates events to move a single virtual mouse pointer)<br>
<br>There is no native multi touch on these devices.<br><br>That does not say that it is impossible to obtain lower resolution multiple contact points and an expanding/contracting zone from this averaged data - it is something I have actively investigated and tested in code on the device (thank you x-fade, i've not forgotten).<br>

My dear friend,<br>
<br>
I welcome your comments on multitouch howto.<br>
I work in my spare time with one multitouch group in Japan, another in UK, one again in Sweden, not to say New York, MIT , UoT.<br>
So multitouch in maemo works as it works.<br>
I can use 2 fingers to move web page horizontally ( it works for semantic pages).<br>
And once again.<br>
It works without stylus with 2 fingers only.<br>
Just have a try not guess.<br>
<br>
This is just the reason for a subject line in my thread.<br>
maemo by Nokia was very very close to multitouch interfacing<br>
and still is.<br>
<br>
I was really surprised to hear , some maemo developers try to close the multitouch thread not to let us sing one day<br>
We are the Champions.<br>
<br>
Multitouch is exactly about maemo development.<br>
<br>
Darius<br>

</div>I am always impressed with intelligent high-tech gizmos, solutions, technologies.<br>
Making maemo multitouch is still an open choice.<br>
patent claims make set no special restrictions to development of<br>
other multitouch solutions - interfaces.<br>
<br>
We are the leaders. Aren't we ?<br>
Visit my multitouch Microsoft surface computing Semantic Magazine to learn more about other multitouch technologies.<br>
