Features		Representative quotes
Main barriers to use
	Cost-efficient	Context: the burden of out-of-pocket expenses for therapy beyond the number of funded rehabilitation treatments they can receive.
		Adult participant: …for people without money I don’t think that’s fair
	Assurance of therapeutic improvement	Context: how busy lives make it challenging to commit to a home-based rehabilitation program.
		Adult participant: We don’t have time, but if you said this is going to help you then we would do it…so you have to say I’m going to do this every day for fifteen minutes, say, or whatever. And if it works and someone like me, you see a difference, well it spurs you on, right?
Main enablers to therapy
	Distinct exercises from those practiced in the clinic	Context: technology as motivation for rehabilitation by offering alternative exercises to those performed in the clinic.
		Adult participant: …it’s so boring to sit there and roll a towel up.
	Game-based therapy to generate results	Context: importance of repetition of exercises in stroke rehabilitation.
		Adult participant: In my exercises I’ve got a basketball I just play with myself in the garage just trying to use my left hand [the affected limb] back and forth and just, like, do it over and over again…as long as I can tolerate it.
	Simplicity of set-up and operation	Context: suggestions for developers of game-based rehabilitation tools.
		Adult participant: Just to make it simple
		Adult participant: …we need things that are very plain, very simple because computers I mean he [his son] had it from kindergarten on. It’s so different for all of us right?
