My application (mathematic drills for children) offers a single
window interface where the contents of that windows changes to
present 'screens'. The UI is completely custom.
When the contents represent the 'drill screen' (where users answer
math problems), input is primarily done via the keyboard (users can
enter digits '0' through '9', use delete/clear to clear the current
answer, and return/enter to move on to the next problem.
Speech recognition and Ink can also be used as input methods.
I also recently added a preference to show an on-screen numeric
keypad (basically buttons representing each of the keys outlined
above). Initially, I marked those buttons as not to receive keyboard
focus and also not be included in the accessibility hierarchy. After
all, I thought that the buttons would only be useful in kiosk
stations where no keyboard is present. Users would thus touch the
buttons via a touch-screen.
However, I'm now thinking that such buttons may be useful by
assistive devices as well. For users of assistive devices, this
would allow them to interact with drills either by simulating
keypresses or interacting with the buttons. Is one type of
interaction more common among users of such devices?
Finally, because this is a custom UI, my button objects don't yet
know about keyboard equivalents. Not sure if that would have an
impact or not.
Thanks,
