The paper presents new interaction techniques for large touch tables and large-wall projected screens. The extended projected screen is integrated as an extension to the touch table where the user can grab the menu items on the projected screen from the touch table or by interacting directly with the projected screen using hand gestures. The system proposes multi-touch controls and hand gestures that aim to minimize the user effort and body movements while interacting with the large touch table and the extended projected large-wall display. We implemented three touch interaction techniques for large display touch surfaces and two hand gestures techniques for interacting with the large-wall projected display. The proposed touch techniques are the “Dynamic Pie Magnifier”, “Poly-Fingers Grab”, “Five Fingers Shadow Grab” and another hand gestures for interacting directly with the large-wall projected display. We studied different techniques for interacting with large displays and our results showed that the proposed techniques are better in terms of time and accuracy.
