Byline: Per Baekgaard [pgba@dtu.dk] (a,*), Shahram Jalaliniya [shahram.jalaliniya@mah.se] (b), John Paulin Hansen [jpha@dtu.dk] (c) Keywords Assembly manual; Eye tracking; Pupil dilation Highlights * An eye tracking study comparing booklet and tablet toy construction manuals. * Subjective responses confirmed tablets were easier to use. * Booklet manual caused stronger pupil dilations when encountered first. * The least productive children had significantly different pupil dilation patterns. Abstract We conducted an empirical study of 57 children using a printed Booklet and a digital Tablet instruction for LEGO.sup.[R] construction while they wore a head-mounted gaze tracker. Booklets caused a particularly strong pupil dilation when encountered as the first media. Subjective responses confirmed the booklet to be more difficult to use. The children who were least productive and asked for assistance more often had a significantly different pupil pattern than the rest. Our findings suggest that it is possible to collect pupil size data in unconstrained work scenarios, providing insight to task effort and difficulties.
