Binocular interface: Interaction techniques considering binocular parallax for a large display

There have been many studies on intuitive user interfaces for large displays by using pointing movements. However, if a user cannot reach a display, object manipulations on the display are difficult because the user will see duplicate fingers due to binocular parallax. We propose Binocular Interface, which enables interactions with an object by using two pseudo fingers. In a prototype, pointing positions on the display are estimated on the basis of the positions of eyes and a finger detected by an RGB-D camera. We implemented three basic operations (select, move, and resize) using duplicate fingers and evaluated each operation.
