We have made the simple design interface; our inspiration is the interface developed by Pebble smart watch. In Figure 1, we show the development and interface levels in Figure 2 we show the steps to turn off the bedroom light. We want to emphasize that this interface is currently running on the screen of the RPI, and the left button corresponds to the motor imagery event left and enter the motor imagery event right button. besides us, we should highlight pending usability evaluation of this interface. An intermediate design is shown in Figure 3. and design we have now interface in Video.
