You could video them now for no extra cost using smartphones, as people already have done as is evident from this thread, but going forward it would seem a natural evolution to incorporate a camera into the digital clock design though I agree there could be an extra cost to bear.Stewart Reuben wrote:Chris Rice >Would arbiters welcome the idea to make it standard that all digital clocks be fitted with a camera?<
Wouldn't that be costly? Having more arbiters might be cheaper. The video camera might well not record what happened because somebody's hand might get in the way. Incidents are rare in chess. That is why they are remembered when they occur. Avoiding them is the trick.
Electronic boards also help. They are particularly useful for the U8 and U9.
I suppose there could be a sensor in each piece that indicated when it was touched.
Where an incident is not clear then an arbiter can ask for the play to continue, you get that in various incidents in cricket where the batsman is given the benefit of the doubt, but regardless the percentage increase in getting decisions right should increase significantly.
I guess the stats on how many incidents occur have never been collected but when the incidents do occur then you can get huge explosions where players feel they have been cheated. It reminds me of John McEnroe who used to go mental over faulty line calls but since Hawkeye was brought in these hardly ever happen anymore and players accept this arbitration as standard these days.
Finally extra arbiters may not necessarily solve the problem as the example Roger gives indicates and besides wouldn't be a good argument in economic terms as they rack up huge food bills.
