| Abstract | Daily use of electroencephalogram (EEG) could increase the effectiveness for medical applications. However, current brain monitoring technologies lack one or more characteristics necessary for daily use, such as portability, responsiveness or versatility. In this study we developed a portable prototype for high resolution real-time EEG monitoring fully integrated system. The prototype is composed of 112 custom made hybrid capacitive-resistive electrodes and up to 7 reference electrodes. The electrodes are connected together by using a flexible, elastic grid which is attached to an adjustable, link based mechanical headgear. Real time processing was performed using a mobile Compute Unified Device Architecture (CUDA) platform for massive parallel processing of the data. Experiments to test the capabilities of the prototype were performed. The first experiment consisted of monitoring the frontal lobe when applying visual stimulus using a lamp. When the lamp was turned on weak alpha waves were detected, while when the lamp was turned off alpha waves were detected. The second experiment consisted of monitoring the entire motor cortex while moving the right hand. At rest, strong mu-rhythm signals were detected over the entire scalp above the motor cortex whereas when moving the right hand mu-rhythm signals above the left motor cortex area were weakened. Both experiment results matched known brain activity phenomena demonstrating basic monitoring capabilities of the prototype. Furthermore we showed that our system has high portability, usability and capable of high responsiveness on high resolution conditions. The concepts introduced in this paper can not only improve EEG monitoring technologies but also contribute to other areas of wearable computing. |

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.
