It depends on what you mean by a tactile display. Braille displays, which of course are text-only devices at this point, can show an accessible description as though it is an alert message. Specifically, the information is displayed only for a brief period of time, after which the display returns to the item in focus. The duration of the message is normally configurable by the user.

I don’t know whether this method has been applied to tooltips at all.

Haptic devices could use speech to present such information. At the moment, I think this is more of a theoretical than a practical possibility; I am not aware of any implementations.

Then there are the more experimental tactile displays to consider, which have been under development as research projects over a number of years, but none of which has yet resulted in a widely available product. Conventions for using these displays are yet to evolve. Much also depends on their capabilities, for example whether they can detect the position of the user’s fingers, or whether there is a mouse-like pointing deice available (as in the tactile display developed by Metec and the University of Stuttgart).
