| Abstract | Today, smart phones with touchscreens and sensors are the predominant, fastest growing class of consumer computing devices. However, because these devices are used in diverse situations, and have unique capabilities and form factors, they also raise new user interface challenges, and at the same time, offer great opportunities for impactful HCI research. In this talk, I will focus on gesture-based interaction, an important interaction behavior enabled by touchscreens and built-in sensors, which sets mobile interaction apart from traditional graphical user interfaces. I will first talk about gesture shortcuts in the context of Gesture Search [1], a tool that allows users to quickly access applications and data on the phone by simply drawing a few gestures (http://www.google.com/mobile/gesture-search). Gesture Search flattens mobile phones' UI hierarchy by alleviating the need for navigating the interface. Gesture Search has been released and is invoked hundreds of thousands of times per day by a large user population. I will then cover several related projects that furthered our investigation into gesture shortcuts, including using gestures for target acquisition [3], crowd sourcing-based gesture recognition [5] and our early exploration on motion gestures [4, 6, 7]. Finally, I will turn to discuss multi-touch gestures for direct manipulation of an interface, the dominant class of gesture-based interaction on existing commercial devices. Multi-touch gestures are intuitive and efficient to use, but can be difficult to implement. I will discuss tools to support developers, allowing them to more easily create multi-touch interaction behaviors by demonstration [2]. These projects investigated various aspects of gesture-based interaction on mobile devices. They help open a new dimension for mobile interaction. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
