Exploring Relationships Between Interaction Attributes and Experience
Leave a reply
Eva Lenz, Sarah Diefenbach and Marc Hassenzahl proposed the Interaction Vocabulary, obtained after evaluating different interactions through the why-, what- and how- framework (a simplistic form of Goal Oriented Analysis).
|Esteem, focus on the interaction itself, significance of the present moment, relaxing, calming, accuracy, care, appreciation of interaction/product||slow||fast||Animating, stimulating, activating, efficiency, focus on instrumental goal of interaction, expression of willpower.|
|Ritualization, every step is meaningful, rewarding, emphasis on progress and advance of the process, approaching a goal step by step, clear structure, being guided through the process||stepwise||fluent||Autonomy, continuous influence, power and right to change what’s happening at anytime of the process, no barriers, fluent integration in running process, spurring instead of interrupting|
|Instant feedback makes own effect experiential, competence, feeling of own impact creates a feeling of security, you see what you do, makes immediate correction possible, nothing in between, you experience what you do, increase of competence, the instant feedback creates a feeling of recognition.||instant||delayed||Emphasizing the moment of interaction, creating awareness. Centering on the interaction itself rather than its instrumental effect.|
|Influence by intuition, control||uniform||diverging||Unusual, unnatural, amplified, grasping for attention|
|Creates feeling of security||constant||inconstant||Liveliness, suspense, you can’t adapt yourself to it, unreliable, chance as an idea generator|
|Uncertainty, ambiguity, magic, handing over the responsibility (the interaction happens somewhere else), you don’t put much of yourself in it m||mediated||direct||Significance of your own doing, face-to-face contact, experiencing affinity, self-made, close relation to the product, feeling of constant control|
|not feeling as a part of it, feeling of distance||spatial separation||spatial proximity||Personal contact, feeling of relatedness, safety (you know exactly what you did), being a part of it, intensive examination of details|
|Deeper analysis is needed, room for variation = room for competence, room for new ideas, exploration||approximate||precise||Safety, no changes = room to concentrate on something else/competence in other fields, exact idea of result, always exact the same|
|Carefulness, awareness, appreciation, making a relationship with the thing (being gentle with it), being a part of it, revaluation of the action, raises the quality, allows to perform a loving gesture||gentle||powerful||Archaic interaction, sign of strength, power, effectiveness|
|Low challenge, no room to experience competence, no room for improvement, becomes side issue, doesn’t matter||incidental||targeted||Appreciation, significance of interaction, worthy of attention, high challenge, high concentration, room for competence|
|Conscious of the significance of your own doing, assurance, security, goal-mode, seeing what is going on, expressive, very easy||apparent||covered||magic, excitement, exploration, action-mode, witchcraft, deeply impress somebody|

Proportionality Design Method
The principle of Data Quality from the Fair Information Practices insinuates that the information that is obtained from the users should be applied to their benefit:
|“Personal data should be relevant to the purposes for which they are to be used, and, to the extent necessary for those purposes, should be accurate, complete and kept up-to-date.”|
Giovanni Iachello and Gregory D. Abowd use this as a starting point and elaborate the principle of proportionality:
|“Any application, system, tool or process should balance its utility with the rights to privacy (personal, informational, etc.) of the involved individuals”|
Based on this principle, they propose the Proportionality design method:
During the whole development cycle of the application, the different parts need to verify the legitimacy, appropriateness and adequacy of the application:
- Legitimacy: Verify that the application is useful to the user. What is the function that the application cover?
- Appropriateness:Analyse if the alternative implementations with the different technologies satisfy the goal of the application without supposing a risk for the privacy of the users?
- Adequacy: Analyse if the different alternative technologies are correctly implemented.
