Haptic feedback is a technology that provides tactile sensations to users, enhancing their interaction with devices. It uses vibrations or motions to simulate the feel of physical objects or actions, making digital experiences more immersive. For example, when you play a video game, the controller may vibrate to mimic the impact of a collision. This technology is commonly found in smartphones, gaming controllers, and virtual reality systems. By using haptic feedback, users can receive alerts or notifications through touch, improving their overall experience. Devices like the iPhone and PlayStation controllers utilize this feature to engage users more effectively.
