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, making digital experiences more immersive. For example, when you play a video game on a controller, haptic feedback can create vibrations that mimic the feeling of explosions or collisions. This technology is commonly found in smartphones, gaming consoles, and virtual reality systems. By using haptic feedback, developers can create a more engaging experience, allowing users to feel actions and responses in real-time. This can improve usability and enjoyment in various applications, from gaming to mobile notifications.
