Technique
A digital video camera is mounted on a tripod. The moving object of interest is filmed doing a motion with a scale in clear view on the camera. Using video motion analysis software, the image on screen can be calibrated to the size of the scale enabling measurement of real world values. The software also takes note of the time between frames to give a movement versus time data set. This is useful in calculating gravity for instance from a dropping ball.
Sophisticated sport analysis systems such as those by Verusco Technologies in New Zealand use other methods such as direct feeds from satellite television to provide realtime analysis to coaches over the internet and more detailed post game analysis after the game has ended.

Famous quotes containing the word technique:
“The mere mechanical technique of acting can be taught, but the spirit that is to give life to lifeless forms must be born in a man. No dramatic college can teach its pupils to think or to feel. It is Nature who makes our artists for us, though it may be Art who taught them their right mode of expression.”
—Oscar Wilde (1854–1900)
“Every notable advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when it’s more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.”
—Aldous Huxley (1894–1963)
“In love as in art, good technique helps.”
—Mason Cooley (b. 1927)
