haptic interface - Computer Definition
Communication with a computer or electronic device via sensory feedback. Examples are touchscreens and trackpads that deliver a slight buzz or vibration when tapped or pressed, simulating the depression of a physical button or keyboard key. Smartwatches, fitness bands and finger rings that vibrate or tap the wrist for notifications are also haptic devices, the most notable of which is the Apple Watch. The word haptic refers to the sense of touch. See touchscreen, haptic hologram and Apple Watch.
