Study on interface for screen operation to reduce tiredness at practical training using ICT in elementary and secondary education

In the practical training using ICT to learn the basics of industry in elementary and secondary education, it is difficult to operate the screen of the computer while working with both hands using the conventional interface device which operates while holding it in one hand. In response to these problems, we have designed and implemented a prototype of the interface for screen operation which is possible to wear on the back of the hand in our existing study. However, we have found out the problem which is accompanied by the feeling of physical and mental tiredness by becoming conscious of the conventional interface. In this paper, to solve these problems, we proposed and designed the new interface for screen operation that wears one hand and reduces the tiredness despite the use for a long time. Moreover, we conducted comparative evaluation with other interface devices on the reduction of tiredness to use the proposed interface for screen operation by the teachers of industrial education in high school. From the evaluation results, we showed that the proposed interface for screen operation has a high possibility of reducing tiredness in the practical training including work such as the manufacturing compared to other interface devices.
