Compact Interactive Tabletop with Projection-Vision

A method implemented at least partially by a processor, the method comprising:

• illuminating an interactive surface using an infrared source;
• detecting a finger over the interactive surface being illuminated with the infrared source;
• observing a shadow of the finger appearing on the interactive surface based on the finger being detected;
• reflecting infrared by the interactive surface based on the shadow of the finger;
• and
• enabling touch detection by determining whether the finger is hovering or touching the interactive surface based on an analysis of the shadow of the finger.

A method implemented at least partially by a processor, the method comprising:

• detecting a presence of at least one page;
• capturing the at least one page as an image;
• and
• subsequently projecting the image as a virtual representation onto a projection surface.

A projection-vision system that facilitates sensing and projecting objects as images comprising:

• a memory;
• a processing unit coupled to the memory;
• a camera-projection component executed by processing unit and configured to capture an input image using a projector and at least one camera attached to an illuminant;
• and
• an image processor component executed by processing unit and configured to process the input image to yield a display image that is projected onto a projection surface upon which the system is placed.
