Using a Steerable Projector and a Camera to Transform Surfaces into Interactive Displays

The multi-surface interactive display projector (MSIDP) is a steerable projection system that transforms non-tethered surfaces into interactive displays. In an MSIDP, the display image is directed onto a surface by a rotating mirror. Oblique projection distortions are removed by a computergraphics reverse-distortion process and user interaction (pointing and clicking) is achieved by detecting hand movements with a video camera. The MSIDP is a generic input/output device to be used in applications that require computer access from different locations of a space or computer action in the real world (such as locating objects). In particular, it can also be used to provide computer access in public spaces and to people with locomotive disabilities

Location linked information

Thesis (S.M.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2003.Pages 98 and 99 blank.Includes bibliographical references (p. 75-81).This work builds an infrastructure called Location Linked Information that offers a means to associate digital information with public, physical places. This connection creates a hybrid virtual/physical space, called glean space, that is owned, managed, and rated by the public, for the benefit of the populace. Initially embodied by an interactive, dynamic map viewed on a handheld computer, the system provides two functions for its urban users: 1) the retrieval of information about their surroundings, and 2) the optional annotation of location for communal benefit. Having the ability to link physical location with arbitrary information is an essential function to building immersive information environments and the smart city. Public computing systems such as Location Linked Information will enhance the urban experience, just as access to transportation dramatically altered the sensation and form of the city.by Matthew William David Mankins.S.M

Human-Computer Interaction

In this book the reader will find a collection of 31 papers presenting different facets of Human Computer Interaction, the result of research projects and experiments as well as new approaches to design user interfaces. The book is organized according to the following main topics in a sequential order: new interaction paradigms, multimodality, usability studies on several interaction mechanisms, human factors, universal design and development methodologies and tools
