Table 2.

Participants’ concerns with dashboard usability.

Usability element and unique concern type			Illustrative quote
Design
	Font size	It’s very clear to me but I would definitely want to enlarge the size of the font.
	Patient status indicator	I don’t know what [the indicator] is supposed to be. Still I want to figure it out. The person’s goal would be about 6.2 and the actual would be 7.5. Is that correct?
	Reminder functionality	That’s a reminder, oh! That’s a clock symbol. Gotcha. It could be clearer [laughs].
	Patients like me indicator	Not clear that this [icon] is for individual. This [icon] is for group. Up to here [group icon], just add one more figure so that will show more people.
	Star rating	There’s a star over here, on this side, but does it indicate the same thing as the star rating over here? By rating, is that telling me that I’m doing poor, good, with my goals?
	Hover over functionality	No I wouldn’t have known [I could hover over]. Once you clicked, then I realized.
	Goal setting functionality	The end date [for the goal], you’re talking about the last day of your, I don’t get that. The end date [for the goal]. Help me.
Efficiency of use
	Redundancy	I mean those two things [my medical concerns drop down menu] and the message subject [free text; are the same].
Content and terminology
	Historical values	I’d actually like to see what my last three [HbA1c] were.
	Medical jargon	I don’t even know what [microalbumin] is. I’ve never heard of that.
	Diet information	If you could just do something about diet. I don’t see that on there anywhere. I mean, because that’s like a big part of it, like what can I eat, what should I eat.
	Online community	You’re not going to be able to communicate with other patients and talk about the key things they do for support. That might be something you would add.
