| Abstract | Abstract : The amount of delay between activation of a cursor control device and the actual cursor movement on a display device can affect an operator's of cursor positioning tasks. An experiment was performed to investigate time-to- target performance under various processing delays from 75 to 400 ms and several cursor-to-target directions and distances. Subjective assessments by the subjects of the delay's characteristics were also recorded. Results showed large and highly significant effects of both delay and distance. There were smaller effects due to direction. Optimum performance was found to be less than or equal to 75 ms. A Delay Perceptibility Threshold, the point at which half of the subjects perceived the delay, was found at 120 ms, and a Threshold of Annoyance, at which half of the subjects were annoyed by the delay, was found at 212 ms. Keywords: Reaction time, Feedback loop. |
