  We present predictions and projections for hadron-in-jet measurements and
electron-jet azimuthal correlations at the future Electron-Ion Collider (EIC).
These observables directly probe the three-dimensional (3D) structure of
hadrons, in particular, the quark transversity and Sivers parton distributions
and the Collins fragmentation functions. We explore the feasibility of these
experimental measurements by detector simulations and discuss detector
requirements. We conclude that jet observables have the potential to enhance
the 3D imaging EIC program.
