Abstract
A virtual user interface is provided which may be used in conjunction with furniture such as shelves, tables, carts, and so forth. The furniture itself may have no active input/output mechanisms such as processors or onboard sensors. Visual output for the user interface may be projected from an overhead projector onto a plurality of projection surfaces on the furniture. Input, such as a user gesturing towards or touching the projected location of a control element, may be detected remotely.
