Table 1. Subjective ratings of the two interfaces by novice participants.

Statement	Nomon	The Grid 2
	mean (sd)	mean (sd)
I liked writing using X.	5.6 (1.4)	3.9 (1.5)
It was easy to select word completions (the, and, cat, …).	6.1 (0.7)	4.8 (1.3)
It was easy to correct errors.	4.5 (1.8)	3.9 (1.7)

Each response to the lefthand statements was on a scale from 1 (strongly disagree) to 7 (strongly agree). In the questionnaires, the interface name was substituted for X. Mean responses are shown with standard deviations in parentheses. Boldface is used to highlight the means corresponding to a more positive user experience.
