HCI Mini-Presentation M.A.C.S. Project Human Computer Interaction By Jeremy Cooperstock McGill University

M.A.C.S. Team Members: Steve Ingold Maryse Medawar Daniel Sud

M.A.C.S. “The purpose of the project is to gain experience in applying some of the concepts and techniques from the class to a real-world problem” -Jeremy Cooperstock

M.A.C.S. Features electronic calendar alarm whiteboard digital art gallery

Using M.A.C.S user centered design intended user population –average adult –little or no computer literacy –basic reading skills

M.A.C.S. Usage Senarios calendar –add an event –check for an event calendar + alarm –check next day’s events –set alarm accordingly

M.A.C.S. Usage Senarios whiteboard –write a quick note for yourself digital art gallery –display images –add new images –turn it off at night

Prototype Design Evolution ?

Why MACS? Calendars Reminders +

Design Stages Approach paper design storyboard html prototype initial prototype (visual basic) final prototype (visual basic) feedback and re-evaluation of criteria

Paper Design drawing

Driving Concepts visibility feedback clear conceptual model

Storyboard user testing

Initial Prototype (VB) example of design evolution

Final Prototype example of how it involved:

Feedback Provided by the Evaluation Team buttons lacks affordances. whiteboard mode lacks feedback and conceptual model. calendar cannot set the date, touchpad keyboard is a slow input device. photo mode lacks options, and are ambiguous to set. clock has ambiguous enable disable button. Weaknesses

Feedback Provided by the Evaluation Team There is instantaneous and appropriate feedback. The photo settings mode, is a good step by step process. Entering information into the calendar is easy. The system is simple to use for most tasks. Strengths

Evolution of the Interface Buttons |sleep||home| |alarm| |cal| |photo| |board| |help| |sleep||photo| |alarm| |cal| |set pic| |board| |help|

Evolution of the Interface white board: conceptual model created with addition of “Note to Self” and “Written on”. calendar: No touchpad keyboard, other: -addition of time and date viewable in all modes -term shuffle changed to cycle

M.A.C.S. Evaluation Criteria speed of use visibility feedback good conceptual model

HCI Concepts Applied user centered design iterative design
