A Few Notes On Multitouch

[agdaniels]

Just a few things I've noticed with the Droids multitouch implementation, what you'll need,

Simply Draw (multitouch drawing app)
MultiTouch Visualizer (self explanatory)
Smart Keyboard (multitouch keyboard)
Default Android Keyboard


First with simply draw, try and put both fingers very close together and draw, it misses the second touch until you space it apart. Bummer.

Now with multitouch visualizer, put one finger down and touch the other nearby, it only registers the second touch at a certain distance.

With Smart Keyboard, notice how the multitouch implementation works great across the board (test this by holding one key and pressing another), but with letters right next to each other, it drops the first touch.

Finally (and heres some proof that the default android keyboard is actually multitouch), do the same test as you did on smart keyboard. It doesn't visualize the second touch, but it does indeed register a second touch when holding a key. Until that is, you go to keys in close proximity, where it just thinks you slid your finger rather then pressed twice.

Now if this is the reason multitouch isn't fully utilized in the stock US version, I don't know. I don't even really miss it that much, its just a little surprising to me that other phones can do it relatively easily, but the droid struggles. I'd be curious to see how other android phones preformed in similar tests, maybe its something we can tweak or improve within the kernel

The default Droid keyboard already supports multitouch for rapid character input.

You just wrote 4 paragraphs about nothing. I don't even know what your point is. If you try to do a multitouch gesture too close it thinks you're moving the first finger that's all. I haven't seen any other touchscreen phones do it any differently.

MultiTouch keyboard on the iphone... the point I'm making is that you can't fully implement a multitouch keyboard or gestures that rely on close touches due to this limitation.

It does have one of the best onscreen keyboards out there, the multitouch implementation plays a part in that.

That being said, I love my droid and mostly use the physical keyboard anyway, but I think this poses an interesting question as to why the multitouch is the way it is on our phones.

My droid eris has multitouch on PDF's that I open natively? Why not every thing?
