Table 1 Physical properties of the three images that were projected on the large display

	Vertical image	Horizontal image	Gray image
L (cd/m²)^a	11.4 ± 0.4	11.6 ± 0.4	11.1 ± 0.4
Ev (lx)^b	5.2	5.2	5.2

L luminance of the display, Ev illuminance at eye level for the participants
^aL was measured at five points at equal intervals in the vertical and horizontal directions using a color meter (CS-100A; Konica Minolta, Tokyo, Japan) and the mean and standard deviation were calculated (mean ± SD)
^bEv was measured three times at eye level for the participants using an illuminance spectrophotometer (CL-500A; Konica Minolta, Tokyo Japan) and the average value was calculated. The variation in Ev values was very low (from 5.21 lx to 5.26 lx)
