  1. Unit 2: interaction design

  2. 2.1 Models of Interaction

  3. Models of Interaction • Why • To identify the likely root of difficulties • As a framework to compare different interaction styles • Terms of interaction 關於iBon, 以下問題可以分為幾類? Amanda發現iBon的螢幕反光很嚴重 Bob想要訂NBA熱身賽門票卻找不到選項位置 Carol列印收據時找不到收據

  10. Poor Mapping In Articulation • Coverage (input/task) • Relative ease of translation

  11. Different Articulation Effects of the Same Input Language Good mappingfor moving files Not-So-Good mapping for re-naming file extension in batch The framework can be used only for assessing a particular task

  12. Poor Mapping in Performance Disappeared shutdown? • Coverage (input language/core language) • Relative ease of translation

  13. Class Discussion: Poor Mapping in Performance? Cannot shutdown remote PC Press Alt+F4

  14. Poor Mapping in Observation What time is it? HTML editing in Notepad The positive points of the Interaction Framework over Norman’s model: + the ‘language’ concepts + the ‘mapping’ concepts • Coverage (output/task) • Relative ease of translation
