Menu selection experiment that presents a two-zone and a four-zone interface with a menu hierarchy and performance data logging functionality.
The application is based on the accelerometer+gyroscope (with Android's game rotation vector virtual sensor).
- Android SDK 23 (Recommended 25)
- Android Build Tools 25.0.2
- Android Support Repo
- JSON Library (org.simple.json)
- Using gradle build tools, you can either side-load the apk file into a phone from the
apk/folder or import the project in Android Studio and build - Configure the experiment by choosing the various options in the main screen and tap
START EXPERIMENT - The interface will then be presented with the menu to navigate to and the task number/order
- Once all the tasks are complete, the app will display a stats window with a summary of the performance data
- You can tap on the screen at any time to re-calibrate the sensors to use current orientation as a frame of reference
The code is meant to be highly modular and extensible for additional sensors. The Launcher MainActivity.java saves the configuration data (ExperimentConfig.java) to start the experiment. ExperimentActivity.java drives the experiment by doing the following operations (in order):
- registering as a listener to raw sensor values (
SensorListener.java) - piping it to the interpreter (
SensorInterpreter.java) - drawing and updating the view (
ExperimentView.java), the menu items, the pointer, and task information - listening for menu selection events (
ExperimentView.java) - logging data and information related to user accuracy and performance (
ExperimentStats.java) - handing off the the stats to a view object at the end of the experiment (
StatsActivity.java)
