Hi everyone, I have made some updates to the storyboards. The changes are:
- The audio mute checkbox has been replaced by a 2-position switch with the left side for "mute audio" and the right side "audio enabled". - The play and rewind game button is now always visible even if it is disabled. The user can tab focus these buttons and it will report its state. - Added an alternate design to the game control buttons - Play, Rewind, and Restart buttons relabelled and relocated. Refer to page 32 of the PDF. You can download the updated PDF here: http://wiki.fluidproject.org/download/attachments/42009249/Forces-and-motion-01-jh.pdf?api=v2 - Jon.
