This if a mechanism for a touchscreen device that
delivers
mechanical gestures to the screen.
The purpose would be to allow people who use screen
readers (many of whom are blind) to deliver reliable
consistent touch screen gestures to run a screen reader.
A frequent complaint of screen
reader users is that it is
too
easy to execute a wrong gesture on a touch screen
device.
This mechanical gesture deliverer could be something
that
fits over the face of the touch screen device and has one
mechanical button that delivers a touch gesture to the
screen, one button that delivers a double tap, and one
button each that delivers a swipe left, right, up and
down.
The software on the device could be built accessible so
that everything could be run just with these gestures.
This would also allow drivers to operate a device like an
iPhone eyes-free while driving (oops, shot myself in the
foot)
