Midair Gestural Techniques for Translation Tasks in Large-Display Interaction

Table 7

Participants’ comments about the use of interaction techniques.

Interaction technique	Original comments from participants
Palm	“Was easy and quick”; “felt very fluid and natural”; “the most pleasant technique, it was organized in such a way that I did not get distracted by technical problems.”
Fist	“Was the easiest to hit, but it did not recognise my palm so well”; “was so natural to do, for example, when I grab something, and that is why it is so pleasant.”
Pinch	“Getting the pinch was often really hard”; “it was more difficult to perform the task, because it was hard to pose my hand in a way that is visible for the camera”; “it seemed that the camera kept losing track of my hand that was frustrating”; “I did not like this because of the fatigue it caused many times.”
Sideways	“Was slow, and moving left was difficult, I also needed to move a lot and it was hard to hit the target”; “touching edges was hard to learn and hard to use on the left”; “was easy since I did not have to move my hand just take it down when I needed to stop.”
