Accessibility Comments

AppleVis Editor Note: this app was submitted before Usability Ratings were introduced, so one has been chosen on the basis of the accessibility comments made by the original poster. If you have used this app, please post a comment to let us know if you agree with the Rating.

Original Comments: All information available as text is readable and all controls are clearly labeled. There are a couple of buttons for every planet that seem to be confusing, but as far as I can tell, they are for graphics. VoiceOver may have some hickups in reading the beginning of every planet entry. That's because of animation.

VoiceOver Performance

VoiceOver reads all page elements.

Button Labeling

All buttons are clearly labeled.


There are some minor accessibility issues with this app, but they are easy to deal with.
