Bare-hand-based augmented reality interface on mobile phone

This paper proposes an augmented reality interface that provides natural hand-based interaction with virtual objects on mobile phones. Assume that one holds a mobile phone in a hand and sees the other hand through mobile phone's camera. Then, a virtual object is rendered on his/her palm and reacts to hand and finger movements. Since the proposed interface does not require any additional sensors or markers, one freely interacts with the virtual object anytime and anywhere. The proposed interface worked at 5 fps on a mobile phone (Galaxy S2 having a dual-core processor).
