System and method for providing gesture suggestions to enhance interpretation of user input
View Patent ↗A touch system comprises a touch panel having a touch surface and a projector presenting images onto the touch surface. A computer executing an applications program is coupled to the touch panel and the projector. The computer is responsive to contact output generated by the touch panel in response to proximity of a pointer to the touch surface and updates image data conveyed to the projector so that images presented on the touch surface reflect pointer activity. The computer executes a gesture suggestion and writing recognition routine. The gesture suggestion and writing recognition routine performs recognition to convert ink on the touch surface into another object based on a selected interpretation.
1. A method of recognizing ink displayed on a touch panel comprising the steps of:
interpreting displayed ink;
presenting different selectable contextual interpretations for the ink based on the interpreting, each contextual interpretation being a different representation of the same thing, said contextual interpretations comprising at least one text interpretation and at least one graphic interpretation for the ink; and
upon selection of an interpretation for said ink, recognizing and displaying the ink in a manner consistent with the context of the selected interpretation, whereby selection of a text interpretation for the ink results in a representation of the ink being displayed in a text format and selection of a graphic interpretation for the ink results in a representation of the ink being displayed in a graphical format.
2. The method of claim 1 wherein said interpretations are displayed on said touch panel as gesture suggestion icons.
3. A system for recognizing ink displayed on a touch panel comprising:
means for interpreting displayed ink;
means for presenting different selectable contextual interpretations for the ink based on the interpreting, each contextual interpretation being a different representation of the same thing, said contextual interpretations comprising at least one text interpretation and at least one graphic interpretation for the ink; and
means for recognizing and displaying the ink in a manner consistent with the context of a selected interpretation for said ink, whereby selection of a text interpretation for the ink results in a representation of the ink being displayed in a text format and selection of a graphic interpretation for the ink results in a representation of the ink being displayed in a graphical format.
4. A computer readable medium embodying a computer program for recognizing ink displayed on a touch panel embodied thereon, said computer program including:
computer program code for interpreting displayed ink;
computer program code for presenting different selectable contextual interpretations for the ink based on the interpreting, each contextual interpretation being a different representation of the same thing, said contextual interpretations comprising at least one text interpretation and at least one graphic interpretation for the ink; and
computer program code for recognizing and displaying the ink in a manner consistent with the context of a selected interpretation for said ink, whereby selection of a text interpretation for the ink results in a representation of the ink being displayed in a text format and selection of a graphic interpretation for the ink results in a representation of the ink being displayed in a graphical format.
5. The method of claim 1 wherein said at least one graphic interpretation comprises multiple graphic interpretations.
6. The method of claim 5 wherein upon selection of one of the graphic interpretations, the ink is replaced with a graphic object representing the ink.
7. The method of claim 5 wherein upon selection of the text interpretation, the ink is replaced with alphanumeric characters representing the ink.
8. A method of recognizing ink displayed on a touch panel comprising the steps of:
interpreting ink displayed on said touch panel;
presenting icons representing different contextual interpretations for the ink on said touch panel with each contextual interpretation being a different representation of the same thing, said contextual interpretations comprising at least one text interpretation and at least one graphic representation for the ink; and
upon selection of an icon, recognizing and displaying the ink in a manner consistent with the context of the interpretation associated with the selected icon, whereby selection of an icon representing a text interpretation for the ink results in a representation of the ink being displayed in a text format and selection of an icon representing a graphic interpretation for the ink results in a representation of the ink being displayed in a graphical format.
9. The method of claim 8 wherein said different contextual interpretations represent at least text and icons representing multiple graphic interpretations for the ink are presented.
10. The method of claim 9 wherein upon selection of one of the icons representing a graphic interpretation, the ink is replaced with a graphic object representing the ink.
11. The method of claim 9 wherein upon selection of an icon representing a text interpretation, the ink is replaced with alphanumeric characters representing the ink.
12. A method of recognizing ink displayed on a touch panel comprising the steps of:
interpreting freehand handwriting displayed on said touch panel;
presenting a plurality of selectable icons on said touch panel, each icon representing a different type of object consistent with the handwriting such that each object is a different representation of the same thing, said contextual interpretations comprising at least one text interpretation and at least one graphic interpretation for the handwriting; and
upon selection of an icon, replacing the handwriting with the object associated with the selected icon, whereby selection of an icon representing a text interpretation for the handwriting results in the handwriting being displayed in a text format and selection of an icon representing a graphic interpretation for the handwriting results in a representation of the handwriting being displayed in a graphical format.
13. The method of claim 12 wherein selection of the icon representing the graphic representation for the handwriting results in the display of a picture consistent with the handwriting.
14. The method of claim 12 wherein selection of the icon representing the graphic representation for the handwriting results in the display of an ideographic character consistent with the handwriting.
