1. Instron Team Windows ’95 Ben Hayden, Abbey Swank, Vito Ruiz

2. Goals Efficiency Intuitiveness Simplicity Prettiness Introduce Standard Conventions

4. Scenarios Basic Routine –Horatio just wants the data and the pretty graph. –set test parameters –run test –save data Advanced Multi-Test Procedure –A simple test must be run several times in a row [perhaps with different samples]. –set basic parameters –set advanced parameters –run test –save data –if not done:goto 3 Badness10000 –Something goes wrong and the test must be interrupted. –set test parameters –start test –sees something wong –hits HUGE STOP BUTTON OF DOOM! –abandons data, restarts test –rinse and repeat

5. Design Evolution From original software to paper prototype –Two frames as opposed to many –All settings organized and in one place –Frequently used options immediately visible –Removed tons of unnecessary features From paper prototype to heuristic evaluation –Moved ‘number of cycles’ into ‘cyclic parameters’ hidden window –‘Notes’ became one text box –Units button changed to radio buttons –Graph and Chart are now resizable

6. Design Evolution Cont. From Heuristic Evaluation to Penultimate Form –Removed implicit Google conversions –Added unit conversion utility –Labeled units outside of text entry –Added numbers to multi-test pages –Red star to mark required fields –Cyclic graphic –‘New material’ function –Instron Machine Status text –More geometry figures From Penultimate Form to Ultimate Form –Added help status bar –Window stays the same size

7. Interactive Prototype Demonstration

8. What’s your favorite? Heuristic Evaluation –Gave the most and most useful feedback –Evaluators could invoke specific design heuristics –Formal report revealed exactly what the evaluators were thinking in full detail
