The encyclopedia explains the major technical terms used to describe the technologies for the future markets of today, tomorrow and beyond. From A as in app to M as in MEMS right through to Z as in ZigBee.


Technique for calculating or measuring distance

Time-of-Flight (ToF)

A measurement method that captures the time taken to travel a distance to determine the distance, speed or properties of the medium.


Time-of-Flight (ToF) sensors emit a light pulse which is reflected back from the viewed object and received by a detector. For each pixel, the sensor measures the time the light pulse took to get to the object and back again, and calculates the distance from it. A ToF camera thus indicates the range of the object captured by it for each pixel.


Touch-sensitive user interface with which software, for example, can be controlled by touch.
