Descripción: 

In this project, a computer vision based interactive multi-touch tabletop
system called HumanTop is introduced. HumanTop implements a stereo camera
vision subsystem which allows not only an accurate fingertip tracking algorithm but
also a precise touch-over-the-working surface detection method. Based on a pair of
visible spectra cameras, a novel synchronization circuit makes the camera caption
and the image projection independent from each other, providing the minimum basis
for the development of computer vision analysis based on visible spectrum cameras
without any interference coming from the projector. The assembly of both cameras
and the synchronization circuit is not only capable of performing an ad-hoc version of
a depth camera, but it also introduces the recognition and tracking of textured planar
objects, even when contents are projected over them. On the other hand HumanTop
supports the tracking of sheets of paper and ID-code markers. This set of features
makes the HumanTop a comprehensive, intuitive and versatile augmented tabletop
that provides multitouch interaction with projective augmented reality on any flat
surface. As an example to exploit all the capabilities of HumanTop, an educational
application has been developed using an augmented book as a launcher to different
didactic contents. A pilot study in which 28 fifth graders participated is presented.
Results about efficiency, usability/satisfaction and motivation are provided. These
results suggest that HumanTop is an interesting platform for the development of
educational contents.
