The Evidence


Upwards of 75% of people diagnosed with ALS will
ultimately lose their ability to speak
(Hicks & Corcoran, 1993; Saunders et.
al., 1981)



Loss of speech function is common, loss of language
and cognition are not
(Ball,
Beukelman

& Bardach, 2007)



Because ALS is an acquired condition in adults (mean
age of onset 56
-
63), most
pALS

had intact language at
the time of disease onset.


Techno
-
connectedness (use of technology to retain
social contacts, reduce isolation, and normalize
communication) is one of 5 recurring themes
important to pALS
(Fried
-
Oken

&
Bardach
, 2005)



One of the most significant developments in access
technology for individuals with severe physical and
communication impairments has been advances in eye
tracking technology
(
Fager
, Bardach, Russell, & Higginbotham, 2011)



Eye gaze is a promising method of accessing
communication, especially for individuals who were
previously unable to use direct access methods
(Ball,
Nordness
,
Fager
,
Kersch
,
Pattee
, &
Beukelman
, 2010)



Adults with ALS with intact cognition and functional
eye motor control have reported the ability to become
proficient with eye gaze technology in a very short
period of time
(Ball,
Nordness
,
Fager
,
Kersch
,
Pattee
, &
Beukelman
, 2010)



Direct access is typically preferable to indirect access



Premise


pALS had intact language at onset



pALS have different communication needs than the
other populations we typically evaluate



pALS have large overall skill set relative to other media



pALS are into techno

connectedness

Going to be interviewed by my speech
path

Comment to audience: “I like to communicate online
or by text because there isn’t that awkward silence
while I type.”



“I chose this one because of the options on it”



“Remote, camera, the layout and the portability”

“ALS is
kicking my ass, but I'm still fighting. Pretty
much fully paralyzed now, the eye gaze keeps me
connected to the world
.”



“I
would definitely recommend this as early as possible
for people in similar situations. Communication is
everything. Been emailing back and forth with friends
going back 20 plus years
.”
