Abstract
By tracking a user's eyes, an indicia scanning system can make educated guesses as to what the user is interested in. This insight could be useful in dynamically configuring a camera system, configuring an indicia decoding process or even as a method to select data that the user is interested in.
Claims21
A portable computer for reading indicia comprising:
- a processor coupled to:
- a first imaging system for capturing an image within the field of view of the first imaging system, and showing the image on visual display;
- and
- a second imaging system for detecting a gaze of a user;
- the processor configured to:
- determine a gaze coordinate location that the user is viewing on the visual display having the image;
- and
- use the gaze coordinate location to start decoding a region of interest within the image;
- wherein the processor is further configured to monitor a gaze zone coordinate to determine whether the user's gaze is stationary on a point on the visual display for a predetermined time period n, and to re-calculate the gaze zone coordinate if at least one indicia is not found while decoding the region of interest.

A method for reading indicia comprising:
- displaying an image of at least one indicia captured by a first imaging system on a visual display of a portable computer;
- determining a gaze coordinate location that the user is viewing on the visual display having the image from a second imaging system;
- and
- using the gaze coordinate location to start decoding a region of interest within the image;
- monitoring a gaze zone coordinate to determine whether the user's gaze is stationary on a point on the visual display for a predetermined time period n;
- and
- re-calculating the gaze zone coordinate if at least one indicia is not found while decoding the region of interest.
