V3.1 (Feb 1, 2018)

Jump key ("J") tap (press and release):

  • The magnet jumps to it's reflected position on the other side of the bisecting vertical axis (see image 4 below).

Jump key ("J") press and hold (not needed for prototype):

  • As long as the jump key is pressed, a placeholder (aka. "Ghost") appears where the magnet will jump to.
  • Upon releasing jump key, the jump begins.

Jump speed keys (press and release):

  • Number 1 key - jump moves in slow speed
  • Number 2 key - jump moves in moderate speed (default)
  • Number 3 key - jump moves in fast speed

V3.0 (Jan 23, 2018)

Keyboard similar to moving the ruler in Coulomb's Law sim with the addition of a jump key.

With the above cursor key control scheme above, additional keyboard interaction may be needed to facilitate the quick experimentation and discovery. In particular learners who tire easily or have dexterity preferences may find it challenging to repeatedly tap or press cursor keys. In this V3 sketch, the idea is to add a way for someone to quickly "jump" the magnet across the playing area and enable quick experimentation which hopefully leads them to uncovering the intended learning outcomes.
