@stephengduke, I reached out to our resource center for persons with disabilities, here are the responses:
“Our talking map is an X-Y tablet that speaks the location of your finger when pressing on a 2D surface. A tactile map is usually placed on the surface and the user is able to feel buildings or roads and hear them described when pressed.

Another area of virtualization uses Haptics. On a touch screen, for example, controlled vibrations are used to simulate the presence of objects.

A robotic pen can restrict movement to simulate the feel of a 3D object. https://www.3dsystems.com/haptics-devices/touch

Many different haptic devices are being used to guide users as they travel.”

Does this help? Thanks.
