 Opening this ticket as a more permanent reminder of the results of
 investigations in Gci2012, covers multiple components, Sugargames, Paint,
 Physics, Abacus, Chat, Ruler*, Jukebox, Maze.

 *this functionality is now in Level Tool

 "How to integrate into Sugar Wrapper for PyGames:
 The android subset of PyGames includes accelerometer reading. For
 constancy, the same style should be used. The existing Android subset has
 a method accelerometer_reading() that returns the tuple of floats
 corresponding the XYZ coordinate system. This is for a best practice, to
 be consistent between different versions of PyGames. The Android
 subset/project may or may not be official, but consistency is important
 none the less. It also would be convenient for the developers for an API
 to be included that allows returns the direction the device is moving. For
 example, when titling to the left, this method (accelerometer_direction())
 would return “left” or an integer LEFT that has a constant value.
 The backend code for this API would need to be hardware dependent, because
 I was unable to turn up any cross-platform tool that would do this
 automatically.

 Examples of how to integrate the accelerometer into existing Sugar
 activities:

 Paint: Use the accelerometer to move the brush. Have it start off in the
 middle. The brush is “up” moving but not drawing when the screen is being
 touched or the mouse is clicked.
 Physics: use the accelerometer to shift gravity. I.e. tilting to the left
 causes all objects to slide/roll/move to the left
 Abacus: shake to reset back to zero
 Chat: tilt left or right to change the chat window. This is not a super-
 important feature to add.
 Ruler: Measure the tilt from normal (straight up and down) in both degrees
 and radians. Maybe include something about the sine and cosine at the
 given angle. Default to degrees but include an option for radians
 Jukebox: Tilt to alter the speed (away and towards the user). Left and
 right alters the location in the song
 Maze: Control the ball through the accelerometer.
 Any activity that is not included here was evaluated, but there was
 nothing to be gained by adding in accelerometer functionality, in my
 opinion; if there is nothing to be gained, there is no sense in adding it
 into the engine.  "
