| Abstract | We present Portico, a portable system for enabling tangible interaction on and around tablet computers. Two cameras on small foldable arms are positioned above the display to recognize a variety of physical objects placed on or around the tablet. These cameras have a larger field-of-view than the screen, allowing Portico to extend interaction significantly beyond the tablet itself. Our prototype, which uses a 12" tablet, delivers an interaction space six times the size of the tablet screen. Portico thus allows tablets to extend both their sensing capabilities and interaction space without sacrificing portability. We describe the design of our system and present a number of applications that demonstrate Portico's unique capability to track objects. We focus on a number of fun applications that demonstrate how such a device can be used as a low-cost way to create personal surface computing experiences. Finally, we discuss the challenges in supporting tangible interaction beyond the screen and describe possible mechanisms for overcoming them. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
