2. Stepped interaction: Major issue: Navigation Movement in physical spaces When moving in an unstructured, unfamiliar and extensive physical space, attempting to reach a goal which may not be wholly formulated, a user will continually ask: Where am I ? Where can I go from here? How do I get there? What lies beyond ? Where can I usefully go ? Where have I been ? I want to go back
3. Two important features of movement in information space: “Where can I go from here?” is about a movement “How do I get there?” is about an interaction Sensitivity S = SM , SI
4. Examples of sensitivity Physical Space Information Space Label ‘Café’ is the SM cue The labels (Rail, Britain, etc.) are the SM cues Flat panel is the SI cue (SI is an affordance) Grey areas with inscribed text are the SI cues
10. At the end Conduct user studies (Focus group, interview, etc) Prototype evaluation (Between or Within groups) Hopefully, SPSS tells us what significant is End
