@mdouglasbibbey's answer describes a situation where it was impossible to "hear" = feel important information while working on Hubble during an EVA, including haptic feedback when a quick disconnect fitting "clicks" when locked or unlocked, or as diagnostics to determine which of two pumps was running and which not.
It goes on to say:
Working with United Technologies Research Center, to solve this problem, we found a piezoelectic polymer film which could be inserted into the glove, and act as a contact microphone. This film, was then connected to a mini amplifier and speakers, which meant that the astronaut could 'hear' through their hands [gloves]....whatever they were touching, they could hear.
Has the ability to hear, feel, or otherwise sense information through augmentation of a space suit glove ever been used or at least tested in space? Are there at least any plans to do so at some point?
These are not directly related to space or to gloves, but highlight the concept of augmenting tactile feedback to gain more information:
