the spaceship's wings. In addition, to calculate
the angular accelerations and decelerations, the
forces and torques of the spaceship's motors can
be explored. To recognize the learner's knowledge
of this domain, the cognitive student model in
Figure 7 was derived.
PlayPhysics ' multimodal output adaptation
will be determined by the chosen pedagogical
actions. The research by Stone & Lester (1996)
will be employed as a basis for sequencing and
synchronizing diverse, encouraging and praising
behaviors of non-player characters. Sounds and
visuals will be applied to create a feeling of im-
mersion, create narrative progression and set an
emotional state. Colors will be employed to em-
phasize or influence an emotional state. As a result,
colors were mapped to the emotions defined by
Pekrun et al. (2007) using as a basis the work of
Kaya et al. (2004). If the emotion is favorable for
learning, the color corresponding to this emotion
will be displayed on the player-character's suit.
Otherwise a color corresponding to the opposite
