open device
if its a tablet based aac u can do anything but it has to be able to do it
in the usa this is called having an open device.
with an open device you can go from the aac software to the computer desktop.
and run programs like u would on a regular windows computer.
closed device
means that you device can only use the aac software and the device needs unlocking to access windows ( in the usa but not uk)
windows
current version of windows is supplied on the tobii i 12 + and i 15+
older windows device will come with xp or windows 7 etc
dynavox t 10 , t7 , t15
all have android operating system . for example the t10 has android 4.04 operating system
and can not use any windows software
t10 can be a lock or unlocked device
and u can even password lock it.
it is non upgradable , by this i mean u cant up grade from android 4.04 os to the current.
you might be able to but this isnt easy .
pointing / accessing your device
this can be done by
touch - using ur finger or stylus
mouse - using a computer mouse ( not android devices)
head mouse - aqhu giro scopic mouse ( windows and android) works with hand , foot head , if u can move it left , right up and down
then this will work
head pointer stick - u wear it on ur head and the pointer is usually at chin hight
chin switch - it basically a switch you press with ur chin
presure sensertive hand switch - can be altered to suit ur hand puresure
big mac , spec switch etc a button thats medeum to big that u press
progamsble message button - record a message and press to hear it one message per button
puff blow switch - relise on puffing and blowing via a strew
eyegaze
avalible on most windows systems and a few others too
very easy to use when u cant use a mouse or switch
hope this helps
