Every year we are asked to do an interactive project for Kids Day. This year our theme was “Pirates”. My contribution was a Unity3D and HTC Vive mixed reality showcase featuring “Walk the Plank” , “Cannon Blast” and “Knife Throwing”. Walk the Plank was set atop the mast of a pirate ship giving the user a sense of height, approximately 300 feet above the deck. The user walked on a physical wooden plank calibrated to its VR counterpart. Cannon Blast lets you test your aiming skills by firing cannon balls at a competing pirate ship that you were able to eventually sink. Knife Throwing was another favorite that lets the user test their skills in virtual knife throwing.
