Why is there no Dementia TV? What is needed is an actual separate TV that can be used with a basic On/Off, Volume and Channel handset. Very simple. The set up of the stations would be similar to selecting "favourites", but rather than channels, programmes could be chosen, then all the client needs to do is flick from channel to channel like the old pre digital tvs.
There are millions of users who need this service. Sky really is missing out.
Don't clutter the screen with various icons (that could be done via app or secondary remorte). Just basic click and watch. Simple for Dementia sufferers.
