4 Motivation Page 4 If we were to follow Norman's prescription, our design would all be usable but they would also be ugly I argue that the emotional side of design may be more critical to product's success than its practical elements. Emotions in HCI

19 Affect Control Theory Page 19 Emotions in HCI

20 Emotions and Affect Affect is the general term for the judgemental system, whether conscious or sub-conscious Emotion is a conscious experience of affect; emotion is a quick cognitive assessment The uneasy feeling one might experience, without knowing why, is affect Page 20 Emotions in HCI

40 Principal Components Page 40 Emotions in HCI

41 The Dimensionality of Meaning (Osgood et al. 1957) On average, 50% of variation in semantic differential ratings can be explained by three principal components: good, nice....bad, awful strong, powerful weak, powerless active, excited passive, calm This finding was confirmed in hundreds, if not thousands of studies in at least 40 different languages and cultures. Page 41 Emotions in HCI

42 The Dimensionality of Meaning (Osgood et al. 1957) Page 42 Emotions in HCI

43 Affective Meaning (Osgood 1962) Re-interpretation: affective as opposed to denotative meaning. EPA: Evaluation, Potency, Activity as fundamental and universal dimensions of affective meaning good, nice....bad, awful strong, powerful weak, powerless active, excited passive, calm Emotions and language are strongly related Page 43 Emotions in HCI

44 Affective Meaning (Osgood 1962) Re-interpretation: affective as opposed to denotative meaning. EPA: Evaluation, Potency, Activity as fundamental and universal dimensions of affective meaning good, nice....bad, awful Evaluation strong, powerful weak, powerless active, excited passive, calm Emotions and language are strongly related Activity Page 44 Emotions in HCI Potency

45 Primary Emotions in the Affective Space Page 45 Emotions in HCI

46 The World of Emotions evaluation, potency, activity are not simply dimensions of words, but they are the hidden language, the affective Rosetta stone that allows the mind and the body to communicate... (Clore & Pappas, 2007) Page 46 Emotions in HCI

61 Deflections and Control The basic idea of affect control theory can be stated in terms of deflections Page 61 Emotions in HCI

62 Deflections and Control The basic idea of affect control theory can be stated in terms of deflections An individual selects a behaviour that produces the minimum deflections for concepts involved in the action Page 62 Emotions in HCI

63 Deflections and Control The basic idea of affect control theory can be stated in terms of deflections An individual selects a behaviour that produces the minimum deflections for concepts involved in the action Minimization of deflections is described by equations derived with calculus from empirical impression-formation equations Page 63 Emotions in HCI
