| Abstract | A key element in caring for and treating elderly people who are exhibiting symptoms of dementia is understanding the patterns within their activities of daily living (ADL). One class of ADL of importance to both caregivers and doctors is personal hygiene activities within the bathroom, which typically cannot be observed directly for reasons of privacy. An automated bathroom activity monitoring system based on acoustics is described. The system is designed to recognize and classify different activities occurring within a bathroom based on sound. At the end of the day, it summarizes all detected activities and automatically generates a customized personal hygiene behavioral report for the benefit of caregivers and geriatric clinicians. This novel system consists of an infrared sensor which detects entry into the bathroom, a microphone sensor with its associated pre-amplifier circuitry and a laptop running our special software which detects and recognizes sound events in real-time using hidden Markov models (HMMs). Experiments were performed on an actual bathroom and preliminary results are encouraging with most sound recognition accuracy being above 87%. |

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.
