Logical constraints “use reasoning to determine the alternatives. Thus, if we ask the
user to click on five locations and only four are immediately visible, the person knows,
logically, that there is one location off the screen” (Ibid., p. 40). And finally, the cul-

action is arbitrary: there is nothing inherent in the devices or design that requires the
system to act in this way” (Ibid., p. 41). Only the cultural constraints require a higher
level of interpretation and a broader context, which makes them self-explicative.
By exploiting the user's learned cultural background, on the other hand, we can
propose a much richer (and even more effective) interaction. In order to do so, it
is important to be able to analyze the HCI/UI from a cultural perspective. Towards
this end we shall compare two methods for UI annotation and analysis to show their
possible benefits in this process.
