Well, this just goes to show not all elderly are the same. My relatives would love more remotes and hate more strange non physical interfaces. Controlling lights with voice commands vs a (eventually on a remote) button, button wins 100% of the time.<p>The biggest hurdle seems to be discoverability. A physical remote makes sense, and doesn't change. Buttons have a singular function and context doesn't matter. Apps are different beasts, navigate up/down/forward/backward (thus context (what did you do before, now doing x does y, but otherwise z)) is just met with glazy eyes. Going back and front just makes no sense, why sometimes you need to go to a menu and other times it's a shortcut button, makes no sense, especially when summoning the menu needs special navigation. To add insult to injury, every now and then apps get an overhaul, and suddenly navigation and buttons changed/looked different.<p>Now when i say apps, i do mean apps on phones/tvs. The windows UI works for them because the basics are the same for all programs, using word or outlook, menu items have text like "send" "save" and while it takes time, functionality is discoverable. But for tv apps the logic is "click up or down until the icon you want has a different hue, then press a button on the remote to do stuff, but only when the screen shows x,not when it shows z". It's too much functionality condensed in too little UI. I'm constantly baffled by design choices for apps that are supposed to be used by everyone, I'm sure it looks nice to designers and devs, but have they even tried showing their brand new TV interface (these are the worst offenders) to an elderly and gave them simple tasks?
