2. Overview Jonathan McKay |CSE 440 Fall 2008 Problem- Parking can suck See ex. on the right How do we make an easy to use application to solve the problem? Contextual Inquiry Experience Sampling method Tasks and Sketches

3. Problem - Solution Jonathan McKay |CSE 440 Fall 2008 30% of traffic congestion is from difficulties in parking Frustrating No advance information Application that can inform drivers about parking availibility Take guessing out of the equation Go straight to your spot

4. Contextual Inquiry- What we Did Jonathan McKay |CSE 440 Fall 2008 3 Contextual Interviews in the Master-Apprentice model Alis, Windy and Justin- All were UW students Differing levels of driving experience Tried Parking in different neighborhoods of Seattle

Based on drivers’ current strategies for finding parking. Also a way to find a lost car. Some drivers have a choice as to whether they should take public transit or drive Finding available parking is useless if the driver does not know how to get there
