This is the most simple, straight-forward and workable solution. Trying to teach elderly people involved usage of technology will be frustrating to them and everybody else. All they really need are social connections/emotional support and little bit of entertainment (source: living with and taking care of my Mother for the last decade of her life). Teach them simple things/phrases and have them use it on auto-pilot without too much thought. Automating the calling of people (Audio/Video) is the number one need/requirement. For further safety having a cctv-like setup so somebody can always check on them/interact with them remotely is also best.
