Measuring the Arrangement of Multiple Information Devices by Observing Their User's Face

We propose to measure the 3D arrangement of multiple portable information devices operated by a single user from his/her facial images captured by the cameras installed on those devices. Since it becomes quite usual for us to use multiple information devices at the same time, previous works have proposed various styles of cooperation among the devices for data transmission and so on. Other previous works propose to coordinate the screens so that they share the role of displaying contents larger than each screen. Those previous works obtain the 2D tiled arrangement of the screens by detecting their contacts with each other using sensing hardware equipped on their edges. Our method estimates the arrangement among the devices in various 3D positions and orientations in relation to the user’s face from its appearance in the image captured by the camera on each device.
