Optical reader with independent triggering and graphical user interface
First Claim
1. A system for electro-optically reading indicia having parts of different light reflectivity, comprising:
- (a) a housing having a handle for gripping by a user'"'"'s hand;
(b) scanning means within the housing for scanning an indicium to be read, and for generating an electrical signal indicative of the indicium; and
(c) control means for controlling the scanning means, and for processing the electrical signal, including a graphical user interface display on the housing and a movable positioning element accessible to the user, said control means including means for displaying icons and an indicating cursor on the display, said cursor being movable over the display as the positioning element is moved by the user to a selected one of the icons, said control means being operative for executing a function associated with the selected icon.

Abstract
A system for reading indicia such as bar code symbols having a scanner for generating a scanning light beam directed toward a symbol to be read; a first actuator manually displaceable from a first position to a second position for producing a first light beam for aiming or positioning the reader, and a second actuator manually displaceable from a first position to a second position for initiating a scanning beam pattern for reading the symbol. The actuators are independently operative of each other. A detector receives the reflected light from the symbol and produces electrical signals corresponding to data represented by the symbol. A graphical user interface with icons simplifies system control functions.

10. A method of electro-optically reading indicia having parts of different light reflectivity, comprising the steps of:
-
a) gripping a handle of a housing by a user'"'"'s hand; b) scanning an indicium to be read, and generating an electrical signal indicative of the indicium; and c) controlling the scanning step, and processing the electrical signal, including displaying a graphical user interface on the housing and providing a movable positioning element accessible to the user, said controlling step being performed by displaying, icons and an indicating cursor, and moving the cursor by moving the positioning element to a selected one of the icons and executing a function associated with the selected icon. - View Dependent Claims (11, 12)
