tactile

This word describes a physical interaction that triggers a sensory response through the skin. It suggests a tangible, hands-on experience where the texture, temperature, or weight of an object is the primary source of information. In modern design and technology, it refers to the physical feedback a user feels, such as the click of a mechanical keyboard or the vibration of a phone. This distinguishes a physical sensation from a visual or auditory one, emphasizing the intimacy of touch.
