Isaac (camera phone)

Isaac was a personal digital assistant (PDA) for people with intellectual disabilities which enabled them to communicate using pictures. It is believed to be the earliest camera phone and wireless photo system, since it was used to capture and transfer digital photos to an image server at a support center beginning in 1994. Isaac combined a personal digital assistant, a digital camera, a Global Positioning System (GPS) receiver, and mobile phone modems for voice and data. Named in honor of Isaac Newton, the system was conceived by Professor Bodil Jönsson in 1993 and constructed in 1994 by Jönsson, Lars Philipson, Arne Svensk, and their colleagues in the Center for Rehabilitation Engineering (Certec) at Lund University in Sweden. By the end of 1994, Certec had built and deployed 25 Isaac units, which transmitted digital photos over standard cellular networks to an image server at a support center.
