  1. Alarm Clocks • Jake Graham | Leighton Makoto Ige | Sarah Leavitt • Human Factors and Interface Design • Franklin W. Olin College of Engineering • May 2, 2005

  2. Design Process to Date • Project Selection-Primary User Groups • Conducted Interviews • Developed Personas, Scenarios, and Lexicon • Formulated Initial Design Ideas • Created Low-Fidelity Prototype • Conducted Interactive Interviews • Created First Interactive Prototype • Heuristic Evaluation • Created Second Interactive Prototype • Conducted Pilot Usability Study • Making Revisions to Second Interactive Prototype

  3. Project Selection • Hardware-Software Integration • Manageable Sized Project • Meaningful Design • Ability to Implement our Results • Alarm Clock! • Insufficient & Inefficient Design • Brainstorming Session • Personal Experience with Alarm Clocks

  4. Interview Highlights • Analog vs. Digital Users • Multiple Alarms / Alarm Clocks • Irregular Sleeping Patterns • Outrageous Ideas about Waking Up • Seriousness of Problem

  5. Personas • Jackie Lee • College Student • Melvin Jefferson • CPA • Doris Jefferson • Librarian Archivist • Richard Sterling • .com Millionaire

  6. Scenarios • Set and Arm Alarm • Wake Up and Turn Off Alarm • Use Radio

  7. Modality • Learning applies to all modes • Simple visual feedback • Color • Flashing • Display

  8. Scroll Wheel • Analog Analogue • Reduces number of buttons • Allows one-handed control • Forward/backward scrolling • CW/CCW motion parallels analog clock

  9. Random Chase • Verifies user’s consciousness • Unpredictable • Deactivation process takes time • Does not allow for incomplete deactivation

  10. Reduction Snooze • Snooze Time Decreases • Set Starting Snooze Time • Finite Amount of Snooze

  11. Low-Fidelity Prototype

  12. Interaction Flows

  13. Changes from Low-Fito First Interactive • Menu System • Menu Options vs. Multiple Presses • Hardware to Software • Limitations due to time • Radio Functionality • Color / Lights

  14. Heuristic Evaluation • Problem Highlights: • Functionality • Prevent Errors • Speak the Users’ Language • Majority of problems already known • Majority of problems mitigated by physical prototype

  15. Interactive Prototype-Take Two • All Severity 3+ Fixed • Fixed Implementation Errors • Functional (radio) • Preventive (radio) • Few minor problems postponed

  16. Pilot Usability Study • Gave users no background information • Went through tasks one at a time • Most took <25 seconds • Hints given when users got stuck • Error-prone tasks • Setting alarm • Using radio • Overall, very positive • Good Feedback

  17. Interactive Prototype

  18. Live Demo • http://fsweb.olin.edu/courses/engr3220/sa2004/engr3220-violet/phase5/violet_phase5.html

  19. To-Do List • More 3D looking Flash Prototype • Iron out few remaining bugs • Radio preset functionality • Colors/schemes of buttons • Discuss toggle interface

  20. Lessons Learned • Users want controlled defeat-ability. • Good design is not necessarily innovative. • Paper prototyping works well. • Say what you mean. • Formal Usability Study we designed would have been very beneficial.
