Text selection using HMD head-tracker and voice-command
A joint head tracker and voice command in a headset computer enables hands-free user text selection. The method and system enables an end-user to select sections of text without requiring use of a mouse cursor control input device. Embodiments include a headset computer, including a processor, configured to display text in a screen view. The computer further configured to place a first point within the displayed text according to one or more of first head tracking information, first voice commands and first gestures, and place a second point within the displayed text according to second head tracking information, second voice commands and second gestures. The computer further configured to select a text section between the first point and the second point in response to one or more of third head tracking information, third voice commands and third gestures, and display the selected text section as a highlighted text section.
1. A computer-based method of selecting text, comprising:
with a headset computer, including a processor, the headset computer displaying text in a screen view:
placing a first point, characterized by a first symbol, within the displayed text according to one or more of first head tracking information, first voice commands and first gestures, the first symbol periodically appearing and disappearing for a predetermined duration after being placed;
placing a second point, characterized by a second symbol, within the displayed text according to second head tracking information, second voice commands and second gestures, the second symbol periodically appearing and disappearing for a predetermined duration after being placed;
selecting a text section between the first point and the second point in response to one or more of third head tracking information, third voice commands and third gestures; and
displaying the selected text section as a highlighted text section.
2. The method of claim 1 , further including making the highlighted text section available for a common operation.
3. The method of claim 2 , wherein the common operation includes one or more of copy, paste, cut, move, email and forward.
4. The method of claim 2 , wherein the common operation is selectable by one or more of (i) a pop-up option window and (ii) a drop down menu.
5. The method of claim 1 , wherein placing the first point or placing the second point further includes manipulating a pointer within the screen view until the pointer reaches a desired location, and using one or more of a particular voice command or a particular gesture to instantiate the first point or second point.
6. The method of claim 5 , wherein the pointer includes an associated symbol that provides one or more of (i) a text magnifier and (ii) a text delineator.
7. The method of claim 1 , wherein the first symbol is a bracket and the second symbol is a bracket.
8. The method of claim 1 , wherein the highlighted text section is characterized by a colored background.
9. A system for facilitating hands-free text selection, comprising:
a headset computer, including a processor, configured to:
display text in a screen view;
place a first point, characterized by a first symbol, within the displayed text according to one or more of first head tracking information, first voice commands and first gestures, the first symbol periodically appearing and disappearing for a predetermined duration after being placed;
place a second point, characterized by a second symbol, within the displayed text according to second head tracking information, second voice commands and second gestures, the second symbol periodically appearing and disappearing for a predetermined duration after being placed;
select a text section between the first point and the second point in response to one or more of third head tracking information, third voice commands and third gestures; and
display the selected text section as a highlighted text section.
10. The system of claim 9 , wherein the headset computer is further configured to make the highlighted text section available for a common operation.
11. The system of claim 10 , wherein the common operation includes one or more of copy, paste, cut, move, email and forward.
12. The system of claim 10 , wherein the common operation is selectable by one or more of (i) a pop-up option window and (ii) a drop down menu.
13. The system of claim 9 , wherein placing the first point or placing the second point further includes manipulating a pointer within the screen view until the pointer reaches a desired location, and using one or more of a particular voice command or a particular gesture to instantiate the first point or second point.
14. The system of claim 13 , wherein the pointer includes an associated symbol that provides one or more of (i) a text magnifier and (ii) a text delineator.
15. The system of claim 9 , wherein the first symbol is a bracket and the second symbol is a bracket.
16. The system of claim 9 , wherein the highlighted text section is characterized by a colored background.
