Abstract
An encoded information reading (EIR) terminal can include a microprocessor, a memory, an EIR device including a two-dimensional imager, and a micro-projector including a light source and a light manipulation sub-system. The EIR device can be configured to output raw message data containing an encoded message and/or output a decoded message corresponding to an encoded message. The EIR terminal can be configured to acquire an image of a target object in a field of view (FOV) of the two-dimensional imager. The EIR terminal can be further configured, responsive to successfully locating decodable indicia within the image, to produce a decoded message by decoding the decodable indicia. The EIR terminal can be further configured, responsive to successfully decoding the decodable indicia, to generate a projectable image and to project the projectable image onto a surface the target object using the micro-projector.
