3D Time of Flight Imaging Solutions

Texas Instruments' 3D Time of Flight (ToF) sensing chipset delivers improved performance over competing 3D imaging technologies. TI's ToF chipset includes a 3D sensor that employs SoftKinetic's DepthSense® pixel technology, delivering higher sensitivity and better motion tracking to enable precise finger, hand, and body tracking.

TI's 3D ToF chipset is inside the 3D cameras that control a laptop or a smart TV to access and navigate movies, games, and other content with a simple hand gesture. For the first time, this technology is coming to the mass market, changing the way we interact with our everyday devices.

Key Features and Benefits

  • Improved responsiveness vs other technologies – less latency
  • Improved IR sensitivity vs competing solutions – reliable gesture recognition
  • More reliable gesture recognition – higher sensitivity
  • More accurate picture – higher frame rates
  • Less expensive and easier to design in to solutions
  • Supported by leading full-body and close interaction iisu® middleware from SoftKinetic
