Abstract

System and method for controlling the presentation of information, such as dynamically displayed text, includes a computer with a display device and one or more sets of electrode plates and capacitive field sensors arranged facing each other on a substantially flat and substantially stationary surface, such as a table top. The method includes forming capacitive fields between the electrodes and sensors by electrically charging the electrode plates. The sensors monitor for gestural movements made by a user'"'"'s hands within the fields by detecting changes in voltage levels of the fields. In response to detected gestural movements, the computer adjusts the manner in which the information is presented in the display device, such as the display rate, information source, font size and contrast control.

Claims

1. A system comprising:

an information database for storing information;

a free hand motion sensor system, comprising;

at least one pair of conductive plates configured to face one another;

a capacitive region defined between the pair of conductive plates; and

at least one sensor coupled to the pair of conductive plates to detect at least one of a presence, movement, and position of a user'"'"'s appendage within the capacitive region;

an information display device to display the information associated with at least one lane of information selected from a plurality of lanes of information based upon the movement of the user'"'"'s appendage, wherein each lane of information is associated with different sources of information comprising one or more of textual, web page, newsfeed, electronic mail, and streaming video feed information, wherein the information display device is configured to dynamically display at least one portion of the information sequentially in a fixed location of a display portion; and

a processing system configured to adjust at least one display characteristic comprising one or more of contrast level, display format and display rate of the information in the display portion of the information display device based upon signals from the presence, movement, and position of the user'"'"'s appendage in the capacitive region.

2. The system as set forth in claim 1 wherein the user'"'"'s appendage is one or more hands.

3. The system as set forth in claim 1, wherein controls for the contrast level, the display format and the display rate are presented for display.

4. The system as set forth in claim 1, further comprising:

a further capacitive region defined between a further pair of conductive plates, wherein the capacitive region and the further capacitive region do not interfere with each other.

5. A method comprising:

maintaining a free hand motion sensor system comprising at least one pair of conductive plates configured to face one another, a capacitive region defined between the pair of conductive plates, and at least one sensor coupled to the pair of conductive plates;

monitoring the capacitive region defined between the pair of conductive plates;

detecting at least one of a presence, movement, and position of a user'"'"'s appendage within the capacitive region;

displaying information associated with at least one lane of information selected from a plurality of lanes of information based upon the movement of the user'"'"'s appendage, wherein each lane of information is associated with different sources of information comprising one or more of textual, web page, newsfeed, electronic mail, and streaming video feed information;

dynamically displaying at least one portion of the information sequentially in a fixed location of a display portion of an information display device; and

adjusting at least one display characteristic comprising one or more of contrast level, display format and display rate of the information displayed based upon signals from the presence, movement, and position of the user'"'"'s appendage in the capacitive region.

6. The method as set forth in claim 5, wherein the user'"'"'s appendage is one or more hands.

7. The method as set forth in claim 5, wherein controls for the contrast level, the display format and the display rate are presented for display.

8. The method as set forth in claim 5, further comprising:

monitoring a further capacitive region defined between a further pair of conductive plates, wherein the capacitive region and the further capacitive region do not interfere with each other.

9. A computer-readable medium having stored thereon instructions, which when executed by at least one processor, causes the processor to perform:

maintaining a free hand motion sensor system comprising at least one pair of conductive plates configured to face one another, a capacitive region defined between the pair of conductive plates, and at least one sensor coupled to the pair of conductive plates;

monitoring the capacitive region defined between the pair of conductive plates;

detecting at least one of a presence, movement, and position of a user'"'"'s appendage within the capacitive region;

displaying information associated with at least one lane of information selected from a plurality of lanes of information based upon the movement of the user'"'"'s appendage, wherein each lane of information is associated with different sources of information comprising one or more of textual, web page, newsfeed, electronic mail, and streaming video feed information;

dynamically displaying at least one portion of the information sequentially in a fixed location of a display portion of an information display device; and

adjusting at least one display characteristic comprising one or more of contrast level, display format and display rate of the information displayed based upon signals from the presence, movement, and position of the user'"'"'s appendage in the capacitive region.

10. The computer-readable medium as set forth in claim 9, wherein the user'"'"'s appendage is one or more hands.

11. The computer-readable medium as set forth in claim 9, wherein controls for the contrast level, the display format and the display rate are presented for display.

12. The computer readable medium in claim 9, further comprising:

monitoring a further capacitive region defined between a further pair of conductive plates, wherein the capacitive region and the further capacitive region do not interfere with each other.
