Abstract
A multi-mode ring scanner (MMRS) has a ring unit for wearing on a finger. The MMRS optionally has a wrist unit coupled to the ring unit, such as via a cable. The MMRS optionally communicates wirelessly with a computing device. The ring unit has one or more scanners (such as an optical scanner or an RFID tag reader). The ring unit optionally has two paddle switches for activation by inward pressure from fingers adjacent to the finger. The two switches enable specifying operation of the MMRS in a plurality of modes and/or to communicate a plurality of information codes to the computing device. The computing device is optionally enabled to assign a function to each combination of activation of the two switches. A scanning system including the MMRS optionally provides feedback to a user based on feedback from a host processor.
