John Travoltage PhET Scenery Integration

Integrate HTML demo with Scenery Model10dJO

  • Added sliders for the arm and leg
  • Linked the sliders to the model
  • Adjusted the arm so the centre position pointed at the doorknob
  • Added value-text to sliders
  • Added discharge alert
  • Alert works in most browser/platform combinations

Issues:

  • VoiceOver is reading the "aria-valuetext" twice
  • Can we not clip the accessible content so that it is discoverable by dragging over the screen in VoiceOver on iOS?
    • need to still be invisible so that they won't interfere with the sim
  • VoiceOver on iOS prevents sound effects. Will play after VoiceOver is disabled.
  • can scene descriptions be dynamic?
Figure out how to calculate the closest position of the arm to the doorknob. Currently we are using a hard-coded number.   
Figure out how to transition the foot between points if jump keys are pressed (Pgup/Dn, Home/End)   
Figure out how to transition the hand between points if jump keys are pressed (Pgup/Dn, Home/End)

John Travoltage Text and Controls Options
