Wow! Can it run acme? I'm wondering because "treats the touchscreen like a one-button mouse" If so, how is the right and middle click used? Anyway utterly cool stuff!

I don't know how well it can run acme, but the acme in plan9port works with touch gestures quite well. Maybe the same gestures could be implemented in Inferno as well.

Hi, I worked on this project, so let me jump in on this. It can run acme, but at this time we don't have a way to do right and middle clicks. I didn't make it a priority, because the accuracy you can get in selecting text on these capacitive screens is just not very good--I don't think Acme would be a very pleasant experience. It worked fine on my old iPaq, but that had a resistive screen and a stylus.

Indeed. I was just thinking I could try it on the device my neighbor has: A very cheap android 2.2 tablet with a resistive screen and pen, no multitouch. Never mind, it can hardly run android apps.

The [Octopus project](http://lsub.org/ls/octopus.html) has an interesting take on gestures. When right-clicking, it pops up a circular menu where the direction one goes in determines the action. See http://lockerz.com/s/139588614 That might be something for touch tablets.

I daily use AcmeSAC on Mac & Win7 with a trackpad (and MagicPrefs for three finger middle click) and with a Wacom tablet and pen. Very nice for editing without RSI problems.

Well, if you can get accurate-enough touch events, you could always go into emu/Android/screen.c and hack around with the pointer event handling code, make it check the state of some of the physical buttons--thus, if you're holding (say) the Home button when you click, it does a left click. Since you have a pen, you should be able to hit the regular window control widgets to minimize/close, rather than relying on our physical button shortcuts.
