Which interaction method is described as more intuitive and quicker to use, but may require specialist hardware?

• A. Speech
• B. Gesture
• C. Touch
• D. VR

Answer: (B)

Gesture input uses natural body movements to control a system, which people often find intuitive and can use quickly because you’re not hunting for keys or buttons. The catch is that recognizing those movements usually requires specialized hardware—things like depth-sensing cameras, motion controllers, or wearable sensors—to accurately track what you’re doing. That combination of being easy and fast to use, but needing extra gear, is what makes gesture the best fit for this description. Speech can be quick and intuitive but depends on reliable recognition and environment noise; touch is fast and uses common hardware; VR relies on headset and sensors and isn’t always the quickest for everyday tasks.
