Secondary touch contextual sub-menu navigation for touch screen interface
First Claim
1. A touch sensitive user interface system including:
- a display screen (20) for displaying a plurality of primary and secondary images (86,92) representative of primary and secondary selectable options;
touch sensitive means (56) for detecting the concurrent presence of at least one of a first probe (84) and a second probe (88) in contact with the display screen (20); and
,control logic (38), responsive to the touch sensitive means (56), fordetermining the first probe contact position,defining for each primary image representative of a primary selectable option, a first probe contact area of predetermined size, over which contact with the first probe selects the primary option,displaying a secondary menu (90) including a plurality of secondary images representative of secondary selectable options, anddefining for each secondary image representative of a secondary selectable option, a second contact area of predetermined size, over which contact with the second probe selects the secondary option.

Abstract
A touch sensitive user interface of the type having a display screen for displaying images representative of menus and selectable list objects, for example; control logic responsive to the touch sensitive user interface for determining the contact position of a first probe and a second probe, such as two separate fingers, thereon, displaying menus including list objects representing primary and secondary features or functions respectively, so that a user may touch a selection on the primary menu with the first probe and subsequently touch an area on the display screen where a contextually related secondary menu is displayed for selection of contextually related features or functions.

8. A touch sensitive user interface system, operated in a xerographic environment, including:
-
a display screen for displaying a plurality of primary and secondary images representative of primary and secondary selectable options; said display screen having associated closely therewith a plurality of light source and light detector pairs arranged with respect to the display screen and defining an array of detection cells thereover, said light sources and light detector pairs arranged to detect concurrent impingement of at least one of a first probe and a second probe at one or more of said detection cells defined thereby, and produce at least one of a first detection signal and a second detection signal indicative of impingement and the location thereof respectively; and
,control logic for providing correspondence between one or more detection cells and the primary selectable options, defining for each primary image representative of a primary selectable option a primary group of cells at which contact with the first probe selects the primary option, displaying a secondary menu including a plurality of secondary images representative of secondary selectable options, and defining for each secondary image representative of a secondary selectable option, a secondary group of cells, over which contact with the second probe selects the secondary option. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for secondary touch navigation comprising:
-
displaying a plurality of primary and secondary images representative of primary and secondary selectable options on a display screen; detecting the presence of at least one of a first probe and a second probe in contact with the display screen; determining the first probe contact position, defining for each primary image representative of a primary selectable option, a first probe contact area of predetermined size, over which contact with the first probe selects the primary option, selecting a primary option by contact with the first probe; displaying a secondary menu including a plurality of secondary images representative of secondary selectable options upon simultaneous contact of the second probe, and defining for each secondary image representative of a secondary selectable option, a second contact area of predetermined size, over which contact with the second probe selects the secondary option. - View Dependent Claims (16, 17, 18, 19, 20)
