1. P.R.E.S.E.N.T.i. Presenting Really Enthralling Slides with an Entirely New Tool Interactively Allen Chew, Charles Essien, Brian Giang, Simon Ma Faculty Advisor: Prof. Lixin Gao Overview What is our project? The problem The Solution Our Inspiration With the rise of the Internet, there is no need to present to a single room at a time. More and more presentations are being recorded and uploaded online for others to view remotely. However, these recorded presentations have many flaws associated with them. Most of the time only the presenter or the slides is visible; leading to confusion, or loss of quality, or expression for the viewers. With new innovations in technologies, there are many new opening doors for opportunity. The Kinect, our innovation of choice, quickly became popular and widely adopted in many research and applicable fields. We created Praser because we wanted to design an application that could compete against the capabilities of the SmartBoard, an provide a feasible solution for enhanced classroom presentations. With our software and the Kinect, one can be recorded simultaneously with the presentation. Praser superimposes a video feed from the Kinect of the presenter on top of a slideshow presentation. Through the use of gestures, the presenter can navigate, annotate and manipulate slides. Praser is a portable presentation solution aimed at creating and capturing a more intuitive, interactive & immersive classroom presentation experience. The application combines the articulation of the presenter’s body language with high-quality, annotation-enhanced slides and delivers the same experience to both in-the-classroom and online viewers. Features Gestures By utilizing the Kinect's motion tracking features, users have the ability to use body poses and hand gestures to do an infinite amount of things. To start tracking the hand, the user must push their hand toward the Kinect or wave to it. Basic hand gestures that this project utilizes are the wave, push, circle, and swipe gestures. The system is not limited to these basic gestures and is definitely capable of creating custom gestures and poses. Team Mosaic Coverflow Prof. Lixin Gao Allen Chew – CSE ‘12 Annotations • An interactive mode to quickly browse and change slides. With a quick spiral motion of the hand, the screen dims and populates the window with a beautiful array of slides. Users are able to spiral through the slides and quickly jump to any selected slides. Brian Giang – EE ‘12 Prospectives Charles Essien – CSE ‘12 Deployment via Browser Sometimes presenters want to add new materials to their slides, or write on them as they do with tablets. By simply bringing the hand close to the screen, a user will begin to write onto the slides, writing in a motion following the hand. Multiple Kinects Recording and Compositing Simon Ma– CSE ‘12 Handwriting Recognition The ability to record the lecture with a high-definition slides and images is a must. By compositing the presenter into the slide, we can retain the image quality as well as bring focus back to the person. No more losing focus of what point the presenter is on. The presenter is able to be on-screen along with the slides to draw attention to specific points on the slides.
