The AttrakDiff questionnaire is typically used to measure the userexperience: it contained 28 items rated on 7-point Likert-like scales scored from -3 to +3 as suggested by Hassenzahl: 7 pragmatic quality items, 14 hedonic quality items and 7 appealingness quality items. Immersion was measured using 18 items from the Immersion Tendencies Questionnaire and presence was measured using 19 items from the Presence Questionnaire inspired from Witmer and Singer (1998). Once the participants have answered the pre-game questionnaires, a professor (Prof. Alejandro A. Franco) explained the aims and presented the peripherals to be used and the actions to be undertaken in order to accomplish our serious game goal.
