We present zPatch: an eTextile patch for hover, touch, and
pressure input, using both resistive and capacitive sensing.
zPatches are made by layering a piezo-resistive material
between silver-plated ripstop, and embedding it in nonconductive fabric to form a patch. zPatches can be easily
ironed onto most fabrics, in any location, enabling easy
prototyping or ad hoc modifications of existing garments.
We provide open-source resources for building and programming zPatches and present measures of the achievable
sensing resolution of a zPatch. A pressure based targeting
task demonstrated users could reliably hit pressure targets at
up to 13 levels, given appropriate feedback. We demonstrate that the hybrid sensing approach reduces false activations and helps distinguish between gestures. Finally, we
present example applications in which we use zPatches for
controlling a music player, text entry and gaming input
