Slide Button. The following steps are necessary for successful activation: When the button is in its neutral state ($S_0$) the mouse cursor has to dwell in the button ($S_1$) until visual and acoustic feedback occurs. Then, the button has to be moved to the right along the rail ($S_2$). At the end of the rail visual and acoustic feedback is given. Next, the button has to be moved to the left along the rail ($S_3$). When the button reaches the initial position ($S_4$), it is activated and the assigned action is performed.
