ENCODED INFORMATION READING TERMINAL WITH MICRO-PROJECTOR
First Claim
1. An encoded information reading (EIR) terminal comprising:
- a microprocessor;
a memory;
an EIR device including a two-dimensional imager, said EIR device configured to perform one of;
outputting raw message data containing an encoded message, outputting a decoded message corresponding to an encoded message;
a micro-projector including a light source and a light manipulation sub-system;
wherein said EIR terminal is configured to acquire an image of a target object in a field of view (FOV) of said two-dimensional imager;
wherein said EIR terminal is further configured, responsive to successfully locating decodable indicia within said image, to produce a decoded message by decoding said decodable indicia;
wherein said EIR terminal is further configured, responsive to successfully decoding said decodable indicia, to repeatedly perform the following steps;
(i) generating a projectable image;
(ii) projecting said projectable image onto a surface of said target object using said micro-projector, so that said projectable image provides a visual reference to said decodable indicia on said surface of said target object;
(iii) acquiring an image of an object in said FOV;
(iv) locating said decodable indicia within said acquired image; and
(v) looping back to step (i) unless a pre-defined condition of termination is satisfied.

Abstract
An encoded information reading (EIR) terminal can comprise 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 of the target object using the micro-projector. The projectable image can include a text string comprising at least part of the decoded message and/or a text string derived from the decoded message. The EIR terminal can be further configured to compensate for terminal movements when projecting the projectable image.
