User interfaces for automatic mode and semiautomatic mode. The CVAR-BCW is developed for indoor environments. The color of the BCW options and the color of stimuli should be different from most objects in indoor environments to reduce visual interference. In indoor environments, there are relatively few red, purple, and orange objects. Therefore, we set the target option, the non-target options, and the stimuli of our BCW to red, purple, and orange, respectively. The orange stimuli were set to be translucent so that users could simultaneously see stimuli and the environment. At the top of the user interfaces, the system automatically displayed the current target (after the text "Target"), the current decoding result (after the text "Result"), and the current BCW mode (after the text "Mode")
