Using Ergonomics in Adjustable Switch Panel Design.

In the field of ergonomics, compatibility is defined as the level of consistency between human expectations and the reality of the relationship between a controller and the controlled component. Therefore, compatibility enhancement is a critical factor that must be considered when designing a system. Researchers have confirmed that when the controller and controlled component are physically similar, their performance (i.e., response time, error rate, and information leakage) is optimal. The objective of this study is to enhance compatibility by applying an adjustable switch panel for decreasing the error rate during operations. An adjustable switch panel combines the switch buttons of the electric light, fan, and other commonly used electric appliances in the same switch panel. The switch buttons are fixed on the switch panel, which is assembled according to the position of the appliances, and a blank button indicates that there is no corresponding appliance. The switch panel can be freely matched and assembled. It can also be arranged according to the available space; moreover, illustrations of the electric light, fan, and appliances atop the switch button enable users to instantly identify the switch buttons. This design also enables several users to use the pane list down the advantages and disadvantages, which can serve as a reference for further design revisions.
