Android Controller
Jeanne Wang
Objective
Create an intuitive and novel approach to a tablet based multi-touch and sensor-enabled controller for a real-time 3D visualization on a 2D platform. Using camera pose information relative to a 3D model displayed on a screen, we can display virtual camera shots in the 3D model space on the tablet.
Android Basics:
- Sandboxed in a linux environment, each application is actually a user
- Model View Controller setup
- Model - Content providers
- View - XML
- Controller - Activity, or Service
- UI Components
- Buttons
Button button = (Button)findViewById(R.id.button1);
button.setOnClickListener(buttonOnClick);- Sliders
SeekBar seekbar=(SeekBar)findViewById(R.id.seekBar1);
seekbar.setOnSeekBarChangeListener(sbar);- TextView
TextView seekbartxt=(TextView)findViewById(R.id.seekBarText);
CharSequence t="slider progress:"+progress;
seekbartxt.setText(t);- Listeners
- OnClickListener
private OnClickListener showCamera = new OnClickListener() {
public void onClick(View v) {
//do stuff here
}- OnSeekBarChangeListener
private SeekBar.OnSeekBarChangeListener sbar = new SeekBar.OnSeekBarChangeListener()
{
public void onStopTrackingTouch(SeekBar seekBar) {
}
public void onStartTrackingTouch(SeekBar seekBar) {
}
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
}
};- Camera

Tips
- Tip: An easy way to add import packages to your project is to press Ctrl-Shift-O (Cmd-Shift-O, on Mac). This is an Eclipse shortcut that identifies missing packages based on your code and adds them for you.
- To get cpuinfo on a particular machine look in: /proc/cpuinfo
- To get ipaddress on a particular machine call /sbin/ifconfig
