Kinect Augmented Reality

We need to setup an augmented reality experience using Kinect. The setup - A TV on the wall shows user on screen, the user stand at a designated area, then icons pop up (augmented) in front of the user, he/she can then click/touch the icons to start (AR) game. There will be 5 scenarios build in to it, for eg. A box with different types of sports balls, like football , tennis ball, cricket ball. 1 ball jumps out of the box and hovers near the users head, the user can then use his hand to hit the ball. Similarly we need to build in Swipe Gesture, Touch Gesture, for a total of 5 different scenarios. Once the user has experience 1 scene, he/she can then move on to the next scene. We need to know the total cost of developing something like this & the time it will take. Can you provide us with some demo videos of earlier work? Is it possible for you to develop a small working demo for our application? Let me know if you need more information. Thanks & Regards, Prashant
