Naoki Higashida is an amiable and thoughtful young man in his early twenties who lives with his family in Chiba, a prefecture adjacent to Tokyo. Naoki has autism of a type labelled severe and non-verbal, so a free-flowing conversation of the kind that facilitates the lives of most of us is impossible for him. By dint of training and patience, however, he has learned to communicate by “typing out” sentences on an alphabet grid – a keyboard layout drawn on card with an added “YES”, “NO” and “FINISHED”. Naoki voices the phonetic characters of the Japanese hiragana alphabet as he touches the corresponding Roman letters and builds up sentences, which a transcriber takes down. (Nobody else’s hand is near Naoki’s during this process.)
If this sounds like an arduous way to get your meaning across, you’re right, it is; in addition, Naoki’s autism bombards him with distractions and prompts him to get up mid-sentence, pace the room and gaze out of the window. He is easily ejected from his train of thought and forced to begin the sentence again. I’ve watched Naoki produce a complex sentence within 60 seconds, but I’ve also seen him take 20 minutes to complete a line of just a few words. By writing on a laptop Naoki can dispense with the human transcriber, but the screen and the text-converter (the drop-down menus required for writing Japanese) add a new layer of distraction.
