The most contentious aspect of the Decision Review System - the ball-tracker - is being put to the test by the ICC at the Cambridge University to establish the accuracy of the two rival tracker systems accredited by the ICC for the DRS.
The ball-tracking technologies currently in use for the DRS - the Hawk-Eye and the Virtual Eye - are being tested by a company called Computer Vision Consulting Limited. The results of the test should be available to the ICC's cricket committee in time for its next meeting in May this year.
Dave Richardson, the ICC's general manager of cricket, told ESPNcricinfo in an interview that the company had been asked to review "the level of accuracy and reliability of the two ball-tracking companies ... In terms of accuracy we want to know whether their virtual depictions of where the ball has pitched and where the ball has impacted the batsman accord with the reality, and whether their predictions as to where the ball would have hit the stumps are correct."
