The main benefit of using haptic feedback in devices is to enhance the user experience by providing tactile feedback. This technology simulates the sense of touch, allowing users to feel vibrations or motions that correspond to actions on the screen, such as clicking a button or receiving notifications. Haptic feedback improves engagement and usability in smartphones, gaming controllers, and wearables. It can also aid in accessibility, allowing users with visual impairments to interact more intuitively with devices.
