V3.0 (Jan 23, 2018)
Keyboard navigation similar to moving the ruler in Coulomb's Law sim with the addition of a jump key.
Cursor key tap (press and release)
- moves the magnet 1 step
- with modifier 1: moves the magnet 1 large step
- with modifier 2: moves the magnet 1 small step
Cursor key pressed and held:
- moves the magnet continuously in a direction after an initial delay.
- with modifier 1: moves the magnet quickly continuously in a direction after an initial delay.
- with modifier 2: moves the magnet slowly continuously in a direction after an initial delay.
In addition to the above, the J key will jump the magnet horizontally to the opposite side.
Evolving Idea (November 30, 2017)
Unlike the v2.0 sketch below, this evolving design idea uses the direction keys to control just the direction - making it simpler to understand and control. Speed is mapped to another set of keys making it easier to just focus on movement once you have a speed you like.
V2.0 (November 17, 2017)
The following is a sketch depicting a possible keyboard interaction for the Faraday's Law simulation (link to Faraday's Law Simulation at PhET). Understanding speed of magnet movement as it relates to flux is an important learning outcome, and this sketch aims to minimize the dexterity / motor function required to successfully gain the learning outcomes.
