How do we know the difference between hot, cold, pain, pressure, and vibration? The skin contains a variety of specialized sensory endings that detect specific stimuli. Together with the brain, these sensory endings comprise the sense of touch. Expose a patch of skin to different sensations and and see which special cells are activated.
