How can projected imagery traverse the digital-physical divide to interact with physical objects and surfaces in the environment? HideOut explores how mobile projectors can enable new forms of interaction with digital content projected on everyday objects such as books, walls, game boards, tables, and many others.
We enable seamless interaction between the digital and physical world using specially formulated infrared-absorbing markers – hidden from the human eye, but visible to a camera embedded in a compact mobile projection device. Digital imagery directly augments and responds to the physical objects it is projected on, such as an animated character interacting with printed graphics in a storybook.
HideOut further extends our work towards a new ‘game projector’ paradigm where the real world becomes a digital playground.
Story books are enhanced with interactive content in a lightweight and exploratory way.
Board game pieces are brought to life with interactive projected imagery.
Our prototype device consists of a mobile projector, a camera, an infrared illumination source, and a button.
Hidden markers in the environment are used as targets in a shooting game.
Scrolling through photos that are dynamically aligned to the environment.
Hidden markers embedded in an interactive storybook.
Hidden markers are tracked in the infrared spectrum to identify board pieces.
A projected character responds to board game pieces to teleport over a wall that stands in its way.
Projected characters can be registered so they appear to ‘pop up’ from the environment.
Markers printed with infrared-absorbing ink are hidden to the eye and can be overprinted with graphics.
