The quality of being tactual (relating to the sense of touch); that which concerns or is characterized by touch.
1858, William Robinson Pirie, An Inquiry into the Constitution, Powers, and Processes of the Human Mind, Aberdeen: A. Brown, Chapter 7, p. 398,
[…] we are just as conscious of a cause of vision as of a cause of tactual feeling, and it is not improbable that we have even a sense of tactuality, if we may so speak, in the secondary sensations.
