A Study on the Effect of Displays for the Performance in Digital Tracking Task

An experimental study was made to compare digital display with analogue-digital display during a digital pursuit tracking task under the preview information. The effect of preview on performance during the tracking task was analyzed for the different preview spans and the different characteristics of the information input. The data from ten subjects revealed that the RMS error performance was improved substantially in the case of one preview point than in that of no preview. It was obtained from the result of the experiments that the improvement ratio of analogue digital to digital display increased to 48%.
