This morning, I posted up a video demonstrating auto-rotation on the OQO. It works pretty good and is nice little utility to have on the OQO. Read more about it on OQOTalk.com and download the application here. Source code is also available here.
It is worth noting that rotation ( automatic and FN Rotate ) breaks on the OQO if you download and install the latest S3 video drivers from Windows Update. If you like rotation on your OQO, stick with the S3 drivers that came with your OQO or available through the drivers site on OQO.
Check it out in this short video demonstrating the automatic rotation application written by Terran.
Ken Hinckley, who works in Microsoft Research, noticed it and posted some really insightful thoughts, and links to video demos, on the use of accelerometers and auto-rotation, and how they have experimented with it over the years.
One interesting use of the accelerometer Microsoft came up with, is the ability to use the accelerometer to sense when two or more tablets were bumped up against each other. This enabled the the displays to join together to make one big display. Fascinating stuff. Watch the videos below - they are hyperlinked.
