Try reading a book with gloves on (or with limited dexterity) and you will understand how difficult it is to turn pages accurately.
Today’s invention is a desktop cutter which shapes the outer edge of any book into steps, just like an old-fashioned address book (but without the alphabetical labeling). It simply involves clamping the edge of the book in place and chopping out a triangular section -so as to create a thumb-able ramp in the paper.
This makes it possible to turn the pages reliably, even with limited tactile feedback.
