Leo: A Braille Display Calculator from Sensory Tools

The people at the Sensory Tools division of Robotron have developed a new type of miniature Mechanotronic Braille Cell that is small enough to make the creation of a Braille display scientific calculator a reality instead of a dream. Unlike a talking calculator, this product allows the visually impaired user to work mathematical calculations quietly. This gives Leo a clear use in classroom, office, library and other settings where noise can be disruptive.

Besides standard arithmetic functions, Leo can perform square root, sine, cosine, tangent, and logarithm operations and their respective inverse functions, conversions, financial functions and more. The display area has 8 cells and can accurately display to 10 significant digits.

The unit is 4.75 by 3.75 by 0.8 inches, and weighs about 10 ounces, including batteries. Rechargeable Nickel-Metal Hydride batteries and a charger are included.
