[oats-sig] New project idea!

Hiya,

this is a new possiblity for the PP team, or anyone here who wants a quick
(?!) project that might be helpful:

Problem:  people who use a touchscreen-keyguard communication aid and have
poor dexterity, but can put their finger into the keyguard holes to select
cells, struggle to access the computer using the same method (since they can
not select an area smaller than the keyguard. 

Also, other people with dexterity problems might have difficulty clicking
exactly on a button, but might be able to reliably click on an area of say
20x20pixels.

Further - people using mouse keys might want another method of selecting on
the screen.

Solution(?): ZoomClick software - every time you click the mouse, the
software blows up a square of the screen every time you click. It then
allows a second click on the 'blown up' area. You can change the zoom
factor.  This is similar to what is used on some eye-gaze systems if you
have seen them

Extension - grid the zoomed area and number each grid so that a) it can be
used with a touch screen-keyguard and b) someone can use a numberpad
keyguard to progressively segment the screen into 9 and click this way.

----

I realise this might not make that much sense, but I've decided to send
ideas into the ether when I have them rather than forget them!!!  Ask/Crit
away!

Cheers,
