| Abstract | Whisper is a new wrist-worn handset, which is used by insertingthe fingertip into the ear canal. A received signal is conveyedfrom a wrist-mounted actuator to the ear canal via the hand and afinger by bone conduction. The users voice is captured by amicrophone mounted on the inside of the wrist. All components ofWhisper can be mounted on the wrist, and usability does not de-crease if the size of components is miniaturized. So, bothwearability and usability can be achieved together. The way Whisperis operated is similar to that of an ordinary telephone handset.Thus, onlookers may not look upon Whispers operation as talking tooneself, even if the associated PDA is controlled by voicecommands. Whis- per is especially effective in a noisy environment.Signals received via bone conduction can be heard clearly in thepresence of noise without raising the volume (-12 dB at noise = 90dB(A) in comparison to cellular phone hand- set). Whisper is alsoeffective in avoiding the annoying problem of the users voice beingraised in a noisy situa- tion. Feedback of the users utterance isboosted by bone conduction when covering the ear canal with afingertip, then the users voice does not need to raised in thepres- ence of noise (-6 dB at noise = 90 dB(A) in comparison tocellular phone handset). Whisper is useful as a voice interface fora wrist-worn PDA and cellular phone. |

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.
