2. -1- Methods-Project 4Pathfinder Contents Prototypes Norman’s Principles Conclusion Q&A

3. -2- Methods-Project 4Pathfinder Prototypes (1) UED: Verify X-DB format –Search by address –Verification by search result Characteristic of this prototype –Intuitive search order 시 / 도  구 / 군  읍 / 면 / 동 –Button active: Not “in your face” but “in your finger” Easy and fast access for Navigation user –Inconvenient for users whose interest is always 2 nd page

4. -3- Methods-Project 4Pathfinder Prototypes (2) UED: Verify X-DB format –Search by address –Verification by search result Characteristic of this prototype –Very visual to the user Utilize the map –Good feedback to the user –Too detail  Hard to choose

5. -4- Methods-Project 4Pathfinder Prototypes (3) UED: Convert POI to X-DB –Open POI file –Convert to X-DB file –Store errors, if occurs –Generate the final report Characteristic of this prototype –Easy to use for novice user (Button)

6. -5- Methods-Project 4Pathfinder Prototypes (4) UED: Convert POI to X-DB –Open POI file –Convert to X-DB file –Store errors, if occurs –Generate the final report Characteristic of this prototype –Difficult to the novice user –Similar environment as the existing one Currently, working on Unix console

7. -6- Methods-Project 4Pathfinder Norman’s Principle UED: Verify X-DB format TypeProsCons Button typeEasy access by button Frequently used type in navigation (Cultural constraint) Inconvenient: 2 nd page access  Reachability Map typeGood natural mapping Easy to know (Affordability) Good conceptual model by given map Inefficient for fast access user (e.g. begin from 읍 / 면 / 동 검색 ) Difficult to select the small region (selective attention) Difficult to find due to lack of order (selective attention)

8. -7- Methods-Project 4Pathfinder Norman’s Principle UED: Convert POI to X-DB TypeProsCons GUI typeAdequate for novice user Progress bar (Feedback) Command line interface Adequate for the experienced user Conventional in customer user group (used to console system, cultural constraint) Lack of affordability

9. -8- Methods-Project 4Pathfinder Conclusion Not GUI oriented project –Not many GUI interface and not complex Viewer/verifier would be adequate for GUI Index editor would be one of good candidates –But, this strongly depends on the data structure –Yet, the design is not finished
