31

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.

3434

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

In Summary

Predict your destinations–Plan once, travel many

Real-time transit data– Just what you need

Destination focused trip planning–Finding a way to get you there

Coming soon to you–Putting all the pieces together
