19. Evaluation

20. Evaluation – Usability Study
Study in 2 phases:
Self-guided exploration, discoverability tested
Functionality demonstrated, understanding tested
6 participants

21. Phase 1: Discoverability
Participant told only about how to use touchtable
Asked to explore system for 10 minutes
Measured which functions discovered without help
Results:
Basic functionality discovered by all participants
Display connectivity consistently discovered
Telepointers not noticed

22. Phase 2: Usability
After discoverability tested, explained functionality

23. Phase 2: Usability
After discoverability tested, explained functionality
Users performed each basic task once

24. Phase 2: Usability
After discoverability tested, explained functionality
Users performed each basic task once
Results: all participants able to complete all tasks

25. After discoverability tested, explained functionality
Phase 2: Usability
After discoverability tested, explained functionality
Users performed each basic task once
Results: all participants able to complete all tasks
Users then asked to do sorting task:
Playing cards randomly scattered on 3 vertical screens & table
Each of screens & table labeled with suit
Instructed to move cards to corresponding screen
Place in correct order on display

26. After discoverability tested, explained functionality
Phase 2: Usability

Users performed each basic task once
Results: all participants able to complete all tasks
Users then asked to do sorting task:
Playing cards randomly scattered on 3 vertical screens & table
Each of screens & table labeled with suit
Instructed to move cards to corresponding screen
Place in correct order on display
Results: participants able to complete task quickly
