We study a version of a modular functor for Turaev's homotopy quantum ΓΏeld theories using 2-categories of surfaces. We deΓΏne the homotopy surface 2-category of a space X and deΓΏne an SX -structure to be a monoidal 2-functor from this to the 2-category of idempotent-complete additive k-linear categor
