Abstract :
The use of networked light bulbs is proposed in order to modify the focus of attention, defined based on salience maps, of a video being displayed on a screen. The proposed system was evaluated by using four networked lamps positioned behind a television display. The lamps were controlled by the system according to the visual features of the video. By using a camera, the salience of the room illuminated by the smart bulbs was recorded and compared against the salience of the room when the lamps were not used. The results showed that changes in color and intensity of the environmental illumination were able to modify the shape of the salience maps of the displayed videos. Two modes of operation are proposed: salience cancellation and salience enhancement.
