		Age group			Computer experience
	All	<= 70	> 70	p-value	Yes	No	p-value
	(n = 99)	(n = 50)	(n = 49)	p-value	(n = 19)	(n = 80)	p-value
Feeling touch-screen mode was easy to use.	91.9%	96.0%	87.0%	0.159^a	100.0%	90.0%	0.347^a
Feeling user-interface of touch-screen mode was user-friendly.	97.0%	100.0%	93.9%	0.117^a	100.0%	96.3%	0.999^a
Expressing they liked touch-screen mode.	91.9%	96.0%	87.8%	0.159^a	100.0%	90.0%	0.347^a
Which version did you like?
Neither	2.0%	0.0%	4.1%	0.117^b	5.3%	1.3%	0.639^b
Paper and pencil mode	30.3%	24.0%	36.7%		31.6%	30.0%

Both	1.0%	2.0%	0.0%		0.0%	1.3%

^ap-value was evaluated by Fisher’s exact test.
^bp-value was evaluated by Chi-square test to compare two groups: touch-screen mode and the others (three versions combined).
