Abstract

A scanning display apparatus includes a display operable to receive driver signals and generate corresponding visual information for presentation on the display, to sense radiation received at the display and generating corresponding sensing signals corresponding to a region proximate to the display. The apparatus also includes computer hardware coupled to the display for generating driver signals for the display and for receiving the sensing signals from the display. The computer hardware is operable to provide an interactive user interface at the display.

4. The apparatus according to claim 1, wherein the computer hardware is operable to execute a first coarser scan to determine spatial location of the one or more objects on or in proximity of the display, and then execute a second finer scan to assimilate finer details of the one or more objects.

5. The apparatus according to claim 4, wherein the computer hardware is operable to present a representation of the one or more objects in a region of the display in which the one or more objects were placed during scanning as confirmation of successfully completed scanning.

6. The apparatus according to claim 1, arranged to present the user interface in squeezed format when the unobscured parts of the display is insufficiently large to include all of the user interface.

7. The apparatus according to claim 6, wherein the user interface includes a scrolling feature for use in accessing squeezed parts of the user interface presented on the display.

8. The apparatus according to claim 1, wherein a minimum display size limit for the user interface is defined in the computer hardware, such that obscuring more of the display than defined by the display size limit causes the computer hardware to present at least part of the user interface in a squeezed format.

10. The apparatus according to claim 1, wherein the computer hardware in conjunction with the display is operable to identify the one or more objects in proximity to or in contact with the display and invoke one or more corresponding software applications for executing in the computer hardware in response to placement of the one or more objects.

11. The apparatus according to claim 10, wherein the one or more software applications are operable to generate one or more animated icons on the display which appear in surrounding spatial proximity to the one or more objects placed on the display, thereby providing a visual acknowledgement that the computer hardware has identified presence of the one or more objects.

12. The apparatus according to claim 1, wherein the display comprises one or more pixel devices capable of both:

(a) generating or transmitting illumination; and

(b) sensing illuminating incident thereupon, the one or more pixel devices being fabricated using one or more of;

(c) liquid crystal display devices with associated thin-film-transistors configured to function as a light sensor; and

(d) polyLED technology.

13. The apparatus according to claim 1 adapted for use in one or more of the following applications:

(a) a contact type scanner;

(b) webtables;

(c) interactive tables;

(d) automatic vending machines control panels;

(e) security access panels;

(f) interactive control panels in vehicles;

(g) electronic design drawing boards;

(h) interactive advertisement or information displays;

(i) childrens'"'"' interactive toys and games;

(j) teaching aids;

(k) television monitors; and

(l) computer monitors.

16. The scanning display apparatus of claim 1, wherein the visual information is adapted so that all the at least part of the visual information moved from the obscured parts are displayed on the unobscured parts.

17. The scanning display apparatus of claim 1, wherein the computer hardware is configured to form a halo surrounding a footprint of the one or more objects to provide an indication of sensing the one or more objects, and wherein the computer hardware is configured to remove the halo upon removal of the one or more objects from the proximity of the display.

18. The scanning display apparatus of claim 1, wherein the computer hardware is configured to perform a coarse scan using ambient illumination to identify positions of the one or more objects and to perform a fine scan, which is finer than the coarse scan, to identify details of the one or more objects using illumination generated by the display.

19. The scanning display apparatus of claim 1, wherein the computer hardware is configured to determine an identity of a user from detection of the one or more objects, and to present preferred visual information preferred by the user.

20. The apparatus of claim 19, wherein the computer hardware is further configured to present the preferred visual information preferred by the user for a duration the one or more objects is in proximity of the display.

21. The apparatus of claim 19, wherein the computer hardware is further configured to determine an orientation of the one or more objects and to orient the preferred visual information based on the orientation of the one or more objects.
