Wow, I love this idea ! Alas, it looks a little slow. (Haven't tried to run it yet, just looked at the videos.) Here's an idea how you could perhaps make it much faster: A long time ago, I discussed with Carsten about what the Glamo could do for us. Predictably, this quickly turned into some rather extensive bashing of this ill-fated chip. On item that came up is the lack of proper support for a feature X11 calls "compositing": http://en.wikipedia.org/wiki/Compositing_window_manager The Glamo hardware has the ability to blend images, but, if I recall our discussion correctly, X11 expects the blending operation to support certain formats which the Glamo doesn't. So the conclusion was that it wouldn't be possible to accelerate full X11 compositing with the Glamo. However, perhaps what the Glamo can do is enough for your full-screen overlay. So you would put the X11 framebuffer in one (off-screen) memory area A, draw the keyboard in an area B, and whenever X11 or keyboard manager have updated their screen content, the Glamo would be told to merge screens A and B into the real frame buffer. This may also make it easy to do things like dynamically changing the respective brightness of the keyboard overlay and the background with the actual content. (*) Now, having said all this, I have to admit that making the Glamo do anything is rather hard, and I've heard that X11 isn't trivial either. But several people have started to work on even more complicated things (DRM, GL, ...), so maybe there's someone who could help making an X server with such functionality. (*) For this, you would have to have a means to "turn on" the keyboard. This could be done by tapping an area where there's no key or where there's a key that doesn't do anything unpleasant (Shift or so), by just absorbing the first tap if the keyboard is dimmed, or perhaps by distinguishing a light touch of the screen from a tap. Oh, and where are the applications ? :-) When Openmoko first announced the Linux-based GTA01, I read a lot of jokes about the kind of user interface a Linux phone would have. Usually they were of the kind "making a phone call is easy and intuitive:" # phone dial -d /dev/ttySAC0 --number=+123456789 --voice But I wonder if something that would make a call with simply # call foobar wouldn't be about as convenient to use as a GUI. Hang up with ^C, background and do something else with ^Z, etc. :-) - Werner _______________________________________________ devel mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/devel
