Do the characters behave in a normal way?
User−centered Interest−centered User or Interest Random
Figure 7.3: Graphical results to the assessment of character normality.
Table 7.1 gives an overview of the mean results obtained for the various questions.
Concerning the first question we asked, about the normality of the character behaviors,
we obtained very similar average results for the four modes. This is depicted in Figure 7.3.
For our second question, which evaluated to what extent the characters were looking at
the user, we have a clear preference for the user-centered and the user or interest modes,
which is in line with our expectations. This is depicted in Figure 7.4. In the user-centered
mode, all characters look at the user when possible. In the user or interest mode, they all
either look at the user or at what the user is looking at. However, the character the user
is looking at looks back at the user. The participant can thus have the impression of being
looked at a lot in this mode as well. In the interest-centered mode, most characters look at
