...

  • The design was to only fire alerts when certain thresholds were passed, not with every action as it appears to be.
  • Users not waiting to listen to whole alert - just hear "magnet at center of play area"
  • For #603 lots of alerts being fired around center during exploration around coil (approx. 2:00)
    • (?JH) The design was to only fire alerts when certain thresholds were passed, not with every action as it appears to be.

    • (question) We can either attempt to fix this so less alerts, or go with grab/release

  • For #603 at 2:50-2:54 Suddenly a different text alert appears “4 loop coil to the right”, but little context. Sudden alert makes it seem exceptional.
    • Something with this implementation doesn’t seem right, not sure why it was triggered here and not earlier.

    • The original intention of this alert is to help users “set up” their magnet so they know when the coil is to the left or right.

    • (question) Perhaps this alert is not needed (user seemed to have figured it out without the alert anyway).

  • Moving magnet around - AT was reporting only play area location alerts

    • (?JH) There were supposed to be coil proximity information too. Unclear what happened to those.

Sonification When sonification and text alert are mismatched

  • For #603  at 2:25, magnet inside coil and hit the top of coil. "bong" sound heard, but text alert says: "magnet at center of play area".
    • Text alert creating confusion because it's not describing what the "bong" sound means
    • Example
      • 6:26 - #603 wonders why there's a different sound.
      • 6:50 - explanation was given
    • Conversely, the example of the edge bump is good because the text alert explains the sound.
  • Text alerts should prioritize coil proximity first (as mentioned by TS in Github issue comments), then magnet location.

Sonification When sonification and text alert are complimentary

  • "Magnet at middle-right edge of play area" alert seemed good. User immediately reversed directions (#603)
    • (warning) Simplify this to just say: "At edge" or "At edge of play area", or remove all together (edge bump may be sufficient).
  • (question) For grab/release interaction, consider adding text alerts for just the exceptional events (coil bump, edge bump).

Missing orientation description of coil relative to play areaAdd coil location to scene summary and circuit description

  • Scene summary currently lacks any information to establish the location of the coil in the play area.
  • Motivation: much of the text descriptions and alerts describe magnet and coil, and yet the coil is not mentioned at all in the scene summary.
WhatCurrentlyProposed
Scene summary"Faraday's Law‬ is an interactive sim. It changes as you play with it.

The play area has a light bulb circuit, and a moveable bar magnet. There are controls that change what is connected to the circuit, flip the bar magnet, and reset the sim.

Move the magnet to play using arrow keys, W A S D, or 1 2 3 keys.

If needed, check out keyboard shortcuts under Sim Resources."

At the centre of the play area is a coil* connected to a light bulb circuit. There is a also moveable bar magnet.

*Change "is a coil" to "are two different coils" if both coils are showing.

Circuit PDOM description (1 coil)"In circuit are a light bulb, a 4 loop coil, and a voltmeter. The coil is sideways, with openings on the left and right.""Connected to the circuit are a 4 loop coil, light bulb, and a voltmeter. The coil is at the centre of the play area. The coil is sideways, with openings on the left and right."
Circuit PDOM description (2 coils)"In a circuit are a:
  • Light bulb
  • 4 loop coil
  • 2 loop coil
  • Voltmeter

The coils are sideways, with openings on the left and right."

"Connected to the circuit are a:
  • light bulb
  • 4 loop coil
  • 2 loop coil
  • volt meter

The coils are at the centre of the play area. The coils are sideways, both with openings on the left and right."

Descriptiveness of text alerts

  • "In 4 loop coil." ... #603 had some confusion about what that meant. (7:40)
