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.
