What type of control method provides a graphic display with items that look like parts of a robot or special symbols?

• A. Text
• B. Visual
• C. Speech
• D. Remote

Answer: (B)

Visual control methods use graphic displays with icons or diagrams that resemble robot parts or use special symbols. This approach lets an operator quickly understand the robot’s status and commands by recognizing shapes and arrangements rather than reading words or listening to audio. The prompt’s description—graphics showing robot-like parts or symbols—fits this appearance and interaction style perfectly. Text-based control would rely on words, which slows recognition; speech-based control uses audio cues; remote refers to the device used rather than how information is displayed.
