I've build a dedicated PC for use in Dental Clinic, but I found out that it's very difficult to setup the computer "idiot-proof" enough. It has to do 2 simple things:
show live preview from intra-oral camera fullscreen
– no snapping pictures or recording videos needed, just show live output fullscreen
– the camera has standard USB interface like any common webcam
ability to play selected short instruction video on demand
– video player with non-desktop look&feel and simple UI = XBMC is great for this.
And there must be the ability to switch between the two with simple keypress.
I'd like to use no mouse at all. The connected mini-keyboard has very poor touchpad anyway...
My temporal solution
I already use a combination of Windows 7 + Cyberlink YouCam + XBMC + AutoHotkey, but this setup has a few major flaws:
something goes wrong every moment, it's not a "press this for camera, and press this for video section"
YouCam quits fullscreen mode every time it pops up some kind of message (connection lost) and after waking from sleep. I have to use touchpad to click OK and then click Fullsceen button again.
Win 7 is overkill for my needs, if I used for example OpenELEC, I wouldn't even need any hard drive. Second, I don't need OS with a desktop here.
Is there any reliable solution? OpenELEC or XBMCbuntu could be nice, but how to setup the system to perform this way?
