<human>:  I have a question about haptic feedback. Why do we feel vibrations when we touch a phone?
<bot>: Haptic feedback is a way of providing a sense of touch to a user. It’s a way of allowing a user to feel what’s happening on the screen of a device without actually touching it. For example, when you touch a phone, you feel a vibration. This is a way of providing haptic feedback to the user.
