Method of and system for displaying product related information at POS-based retail checkout systems
First Claim
1. A bi-optical symbol reading system for installation at a point of sale (POS) station, comprising:
- a system housing having a vertical housing section with a vertical scanning window and a horizontal housing section with a horizontal scanning window adjacent said vertical scanning window;
a laser scanning subsystem disposed in said system housing, for generating and projecting a plurality of laser scanning planes through said vertical and horizontal scanning windows, which intersect within a 3D scanning volume defined between said vertical and horizontal scanning windows and provide a laser scanning pattern within said 3D scanning volume, for scanning each product within said 3D scanning volume and producing scan data for decode processing;
a scan data processor for processing said scan data produced by said laser scanning subsystem in effort to read a symbol on each product passed through said 3D scanning volume, and generate symbol character data representative of each said read symbol;
a digital imaging subsystem, disposed within said vertical section of said system housing, for automatically projecting a field of view (FOV) into said 3D scanning volume, and capturing and processing one or more digital images of each product present in said FOV;
a digital heads-up display (HUD) image projection subsystem, disposed within said vertical section of said system housing, and supporting the projection of a heads-up display (HUD) for each product, on a portion of said vertical scanning window, wherein each said HUD contains price and other information of each product identified during checkout operations at said POS station; and
a system controller for automatically controlling the operation of said laser scanning subsystem during said system operation.

Abstract
A bi-optical code symbol reading system including a system housing having a vertical housing section with a vertical window and a horizontal housing section with a horizontal window adjacent the vertical scanning window; and a digital video display subsystem, disposed within the vertical section of the system housing, and supporting the display of digital images in substantially the same plane as the vertical window during system operation. The digital images displayed by digital video display subsystem can be video images captured by an integrated digital imaging code symbol reading subsystem, to assist the operator in aligning code symbols during scanning operations. The digital images can also be product and price information captured during product scanning operations.

8. A bi-optical symbol reading system comprising:
-
a system housing having a vertical housing section with a vertical scanning window and a horizontal housing section with a horizontal scanning window adjacent said vertical scanning window; a digital imaging subsystem, disposed within said system housing, supporting the capture of digital video of each product presented within a field of view (FOV) of said digital imaging subsystem projected through said vertical scanning window; and a digital video display subsystem, disposed within the vertical section of said system housing, and supporting the display of digital video frames on said vertical scanning window during digital-imaging based symbol reading operations, so as to provide visual feedback and improve symbol and FOV alignment during symbol reading operations. - View Dependent Claims (9, 10, 11)
