Wayne Piekarski, Augmented reality Going through all the different backpacks They keep getting better lca2005 was the smallest yet, but still 12 KG. The latest he has been able to wear under his jacket, very compact. Not even a backpack, it sits on a bumbag The internals are all small and light, the battery packs weight more than the rest (nimh) topics of the talk today arenot about hte hardware (he just wanted to show off the cool hardware) embedded motherboards do not have good 3d support, instead he chopped up a laptop motherboard Had to go for good cpu and video, thus put up with proprietry bluetooth and wifi, however usb allows plugging those items in Mobile computing needs to have a different input method The headmounted display is S-Video out only so you do not see the system starting up. Audio is enabled during bootup when hotplug starts, thus he was able to install festival and have the audio output in speech with some diagnostics Knoppix has no upgrade path without reinstalling, debian stable is far too out of date Debian testing breaks too often, packages different, debian unstable goes without saying. Ubuntu is good as they have all the firmware and recent sort of software in there. he keeps all his extra softwAre in a basic apt repositry and has all important config in cvs so he can have a new system up and running on a new machine in a few hours, without needing to sit in front of the computer while it happens. Wayne is happy bluetooth actually works now days RFCOMM (like tcp code over bluetooth, eaier/beter than standard seriel) Gotchas, have to connecto devices in serial so scan for active devices and only connect to active devices All he slides and notes are going to on the web See his slides for links with references to other places and his own stuff
