A Method for User-Location Estimation for Intuitive Input System on Very Large Display Space

Ultra high resolution display environments have highly efficiency for displaying high definition multimedia content. Tiled display wall (TDW) wall environment is a typical ultra high definition display environment, they use a traditional mouse in order to interact with user of application on display space, and this might to be caused of interaction burden for the user. We developed an intuitive input method considered display space scale independent design using video game input device until now, this system requires exact user-location in front of display space. In this paper, we consider a user-location estimation method in front of display space, applicable to our intuitive input interaction device system. This estimating method uses some depth sensors device in addition to infrared beacon illuminating device and beacon analyzing process in current input method.
