Notes from Sonification Interview videos

  • FL tested with #605, 606, 607 (Early Sep)

  • FL tested with #603, 602, 608, 609 (Late Sep, early Oct)

  • These interviews are working from v1.4.0-jump.9 build of FL (currently 1.4.0-dev.54)

    • A number of changes have been made based on feedback from the Early Sep. group which has not been tested w users.

    • The fundamental issues with the experience with text alerts remain

      • These issues can be addressed with switch to explicit grab/release interaction (see “Oct (for next discussion)” below)


  • PhET io sonification wrapper 1.0.0-dev.77

  • Listened to most of DOM descriptions, and self initiated movement

  • 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.

  • Seems like a lot of location alerts are being reported (i.e. around 2:20 around coil)

    • (?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

  • At 2:50 - 2:54

    • Suddenly a different text alert appears “4 loop coil to the right”

    • (?JH) Something with this implementation doesn’t seem right, not sure why it was triggered here and not earlier. Sudden alert makes it seem exceptional.

    • (?JH) 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).

  • No labels
