Rationale for Task Changes
When the scope of the program changed, so did the tasks– Tagging proved to be a confusing
idea for users.
Why our three final tasks?– They represent the final and most
important three features of the program.
32
Design Evolution
The Home Screen tells users where they are and what trips they might want to take.– Trips are based on their habits at said
time.
MyTransTracker “Home” screenTake Me There “Main” Screen
Design Evolution Cont.
MyTransTracker focused on multimodal transportation.
Didn’t take into account time well in planning screens.

Take Me there asks users in plain English what they’re looking to do.
Ease of use was priority in new trip planning, tends to be overcomplicated.
35
Usability Testing
Web-Based Usability Study– 23 completed testing– 80% used the same routes most of the
time
Emulator-based Usability STudy– Median age = 22
• 3 males, 2 females– All used web-based transit
applications• 3 of 5 used mobile applications
– Users used busses on average 6.8 times/week
36
Usability Results
Users were generally impressed with real-world applications.
Confused by terminology– Tabs were changed from “Home,” “New,”
“Saved” to “Main,” “Plan Trip,” “My Places.”
Confused by icons and labels– Clear separation of buttons vs. text was
implemented.
37
What parts do we need?
Static Location Data– Jim’s house, work
Current Location Information– GPS Information– Map and Direction Information
Transit Information– Bus Status– Trip Planning
Destination Classifiers– Track and learn users travel patterns
38
Future & Related Work
Google maps mobile• Location information• Trip planning• Map content• Detailed trip information
One Bus Away (.org)• UW CSE, Go Dawgs!• Explore your neighborhood• Back end ready to go now• Starting to build a mobile app
