| Abstract | We investigate the feasibility of leveraging platform-integrated ambient sensors (PISs), which are sensors being built into personal computing devices (hosts), to enhance people-centric sensing. PISs can utilize resources (e.g., energy, computation, and communication) from their hosts (e.g., cellphones and laptops). Hence, the sensors have many advantages including low manufacturing cost, ease of deployment, and battery-free operation compared to standalone sensors (e.g., Telosb [1]). PISs, however, have a constraint that they must be attached to their hosts, which may not be their sensing targets (e.g., users). Therefore, it is unclear if PISs are actually useful for sensing applications. We conducted an empirical study of platform-integrated ambient sensor data collected from various locations on a wide range of personal computing devices and locations surrounding a user, who is using the devices. We found that (i) ambient data collected from PISs are close and highly correlated to ambient conditions at the user (ii) sensor placement, host operation mode (e.g., active or power-saving), host computational load, host mobility, and user activities impact PIS readings, (iii) simple models can be developed to estimate ambient conditions at the user from PISs data accurately, (iv) the estimated ambient conditions can be useful for sensing applications such as building management system, and (v) for laptops, PISs and sensing services have negligible impacts on the host and experience of the user. |

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.
