Comment HTML5 + Javascript (Score 1) 194
With the exception of that compatibility with third party stuff that is likely not usable by alz patients, I would think a javascript dev could come up with a simple browser application that leverages HTML5's streaming audio and video capabilities to implement a simple video conf tool using touch screen computers. Perhaps a simple opening split screen that has thumbnail pictures of people the user knows in a sidebar, and a main screen that shows the realtime video.
Push on a face, and it 'dials' that person or whatever, it 'rings' the other end showing the caller's thumbnail pic large, they click the pic to 'answer'. And can do the same with other thumbnails at the same time to bring several people together. A small hangup button at the bottom left of each active video.
I had to make an MP3 player and 'internet radio' app for a technophobic senior, and went this route. Took some time to make the web app full screen properly for the browser + hardware used (a lenovo tablet running Android), but it worked.. all javascript + html5. No other libs or ui toolkits needed.
