Saw the trailer for this a few weeks back and started to cry, but haven't been in the mindset yet to sit down and watch it since it came out.
As an educator who worked with technology, this story is all too familiar. We had a student who used an Eye Gaze device to communicate. His various disabilities left him with the inability to control any of his bodily functions, but he could use his eyes. He ended up living until about 22, but mentally he never moved beyond the toddler stage. He was able to learn how to use the Eye Gaze device to communicate basic needs and wants and he would have been a great "greeter" at a place like Walmart.
His parents refused to let him use the Eve Gaze device at home. He would essentially sit/lay there all summer without the ability to communicate. Infuriating.
