According to Øystein Wiggen, a physiologist and research scientist at SINTEF, “The average worker may be so determined to get the job done that his fingers become cold and lose their dexterity, with the result that screws are not fitted correctly, leading to increased risk level some time in the future. We may well have to use a sort of traffic-light system in such situations, in which green means ‘OK’, yellow means ‘take care’ and red indicates that ‘there is danger afoot.’” Sounds like it is worth an investment, and we do hope to see commercial availability of this project in due time.
