I'm wondering whether a machine exists that can convert English sentences into a sequence of taps or vibrations that a person can feel with their hands. The user would learn the tapping patterns—similar to Morse code—and interpret the message through touch instead of sound or sight.

Braille devices are probably the closest established technology, especially for communicating text through touch. Refreshable Braille displays use moving pins that form characters, while wearable haptic devices can use vibration patterns more like a tactile version of Morse code.
Yes, this is generally done with haptic or tactile communication devices. They use small motors or actuators to create vibrations and taps, and the user learns what different patterns mean. It would work best for short messages unless the person becomes very familiar with the code.
