Seeing Machines designs integrated software and digital camera technology that tracks human movement and facial reactions. Australia-based Seeing Machines began life in July 2000 when it was spun out of the Australian National University – which is still a shareholder. The university had been researching software and digital camera technology for tracking movement and human facial reactions since 1997. It collaborated with Volvo on this research and the Swedish truck maker is also a shareholder in Seeing Machines. Seeing Machines joined Aim in December 2005, when it raised £1.65m at 3p a share. The company has developed four main pieces of technology – faceLAB, Driver State Sensor, TrueField Analyser and faceAPI. The original product was faceLAB, which uses a video-based sensor to track the head, face, eye, eyelid and gaze of a person. This three dimensional product is mainly used as a prototyping tool by research and development organisations. Driver State Sensor technology is used to indicate driver fatigue and distraction and assist drivers in their driving. It can also be used by employers to ensure that vehicles are being driven properly and to help reduce accidents. TrueField Analyser is designed to detect glaucoma and other eye diseases. It is based on a combination of Seeing Machines' own technology and separate technology from the Australian National University. The FDA granted marketing clearance in the US in August 2007. The software library of the group's technologies is known as faceAPI. Seeing Machines receives a licence fee if other companies incorporate the technology in their own products. This could take the technology into new areas, such as computer gaming.
