A computing system includes a display surface that displays an electronic program guide. A sensor is used to sense the presence of an object adjacent to the display surface. Based on the data from the sensor about the object adjacent to the display surface interacting with the electronic program guide, the system determines which gesture of a set of possible gestures the object is performing. For example, the system may determine that a hand is sliding across the display surface or rotating an icon on the display surface. The system will perform a function related to the electronic program guide based on the determined gesture.
