...but probably not for the general public.
Some of these little, strange variations on a theme can be very useful for people with certain types of brain related processing issues.
An example: We have a document reader at the library. It was provided, along with magnifying readers and software, by the Lions Club for visually impaired clients. It scans a page or paper and reads the text out loud (we require headphones) using an electronic voice simulator, to provide access to text that doesn't have an available audiotape or CD equivalent. Those with visual impairment are using the magnifiers, and the large print books, and the audiobooks, but not the reader. Who's using the reader? Dyslexics. Mostly for text books.
Innovations will find their market, if people know they exist.
