It is difficult to design and test location-enhancedapplications. A large part of this difficulty is due to the added complexity of supporting location. Wizard of Oz (WOz) has become an effective technique for the early stage design of location-enhanced applications because it allows designers to test an application prototype bysimulating nonexistent components such as location sensing. However, existing WOz tools 1) require nontrivial effort from designers to specify how a prototype should behave before it can be tested with end users, and 2)support only limited control over application behavior during a test. BrickRoad is a WOz tool for spontaneousdesign of location-enhanced applications. It lowers the threshold to acquiring user feedback and exploring a design space. With BrickRoad, a designer does not need to specify any interaction logic and can experiment on-the-fly with different designs during testing. BrickRoad is a valuable complement to existing tool support for the early stage design of location-enhanced applications.
