Millions of people have reading difficulties or poor eyesight, so they can’t
read medicine labels properly and risk taking the wrong drug. To overcome this
problem, En-Vision America of Normal, Illinois, has created talking medicine
bottles. The company has developed a printer which embeds a microchip in the
label as it is printed. The patient later points a hand-held voice synthesiser
at the label, which uses a beam of radio waves to scan the microchip and read
its message out loud.
