Abstract
A control system includes a control device and a display device. The control device includes plural keys in a specified arrangement. The plural keys are marked with plural first-layer options. Each first-layer option extends plural second-layer options. The display device is in communication with the control device. A display image of the display device includes plural display blocks. An arrangement of the plural display blocks is identical to the arrangement of the plural keys. When one of the plural keys is triggered by a user, the second-layer options extended from the first-layer option corresponding to the triggered key are shown on the display image, and the second-layer options are included in the corresponding display blocks, respectively. A specified option of the second-layer options is selected by the user when the key on the control device and at a position corresponding to the specified option is triggered.
