Tactile acuity subroutine
The tactile acuity subroutine was the program within the EMH Mark I that enabled a hologram to touch objects and use them properly.

In 2372, The Doctor believed there was a malfunction in his tactile acuity subroutine when he began to experience difficulty handing objects. This was actually due to his preoccupation with Danara Pel. ()
