The LeapPad was a popular interactive educational device aimed at children and launched by LeapFrog in 1999.
Cartridges were sold with a book that was placed on the device and allowed children to touch areas of the book with a special stylus to hear words or information about the picture. The device used a sensor to measure current flowing between the stylus and the pad and sense the location of the stylus.
The original LeapPad was replaced in 2008 by the Tag Reading System, and since then other products under the LeapPad name have included the LeapPad Explorer, a tablet-style device, and the handheld Leapster device.
