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) { } };

Hardware + Emulator

Network

  • server
  • client
  • socket issues

ARToolkit

  • detect marker
  • pose

Android

OpenCover

  • display marker
  • display dataset

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

Other possibilities

  • Corona Sdk [[1]]
  • HTML5 DeviceMotionEvent [[2]]
  • PhoneGap [[3]]
