Improving the performance of input interfaces through scaling and human motor models

摘要

The performance of interfaces is affected by human factors, which vary from one person\udto another, and by the inherent characteristics of the various devices involved. A set of\udtechniques has been studied in order to improve the efficiency and efficacy of input\udinterface devices. These techniques are based on the modification of the motor scaling\udfactor, a transformation similar to the known Control-Display ratio (CD ratio).\udOperation time, the accuracy of the task and user workload are the indicators used in\udthis work. By means of models based on the various human motor behaviors, the\udimprovement of such indicators has been demonstrated. Using some common input\udinterface devices, a number of experiments have been carried out to evaluate the\udpresented methodology. The results show that the overall performance of input\udinterfaces is significantly improved by applying such methodology.
