A Glimpse Into A Similar Project

I have been researching the internet about how exactly I am going to pull off getting Denise projected onto my wall.  This concept has been done before however not with Denise to my knowledge.  The idea is to get Denise to be available to appear at any given part of the home to assist me as need be.  If I need her to wake me up, I want her to appear on my bedroom wall telling me to get up. If I need a recipe in the kitchen, I want her to appear on the kitchen wall to give it to me, etc.  I was thinking I was going to need a chain or Microsoft Kinects and projectors setup throughout the house.  However that is jumping the gun at the moment.  First, I  have to get her projected onto the wall before I worry about how I will do this in every room.

I came across a YouTube video of a man who projected his assistant (in this case The Terminator) onto the wall.  He then interacts with the assistant by asking it questions.

This video is very similar to what I tend to accomplish.  I plan on getting Denise projected onto the wall and being fully interactive.  I knew that this small project was something that had been done before, however I could not escape how extremely cool it is.  I knew I had to do this.  Soon.
