SensoMotoric Instruments (SMI) was a German provider of dedicated computer vision applications focusing on eye-tracking technology. SMI was founded in 1991 as a spin-off from academic and medical research at the Free University of Berlin. The company has its headquarters in Teltow near Berlin, Germany, with additional offices in Boston, Massachusetts, and San Francisco, California, in the United States, and a worldwide distributor and partner network.
SMI provided eye tracking systems for scientific research, professional services, and OEM applications. These eye trackers could be combined with motion tracking systems, EEG, and other biometric data. They can be integrated into virtual reality CAVEs, head-mounted displays – such as Google Glass or Oculus Rift, simulators, cars, or computers as a measurement or interaction modality.
