| Abstract | This paper proposes a method for text input based on gestures to be used in smartwatches using geometric shapes. To make the recognition of gestures, we used the incremental recognition algorithm gestures. a template with straight curves were developed using the reduced equation of the circle. Using this template, thirty users have entered all the letters of the alphabet three times each in three groups totaling ninety inserts for each letter. Gestures entered by users have been used to train a Naive Bayes classifier that calculates the probability of insertion for each letter to from the user-entered gestures. During the development work was also carried out a study of the most frequent letters of the Portuguese language. Another partial result of the project is a prototype in which the user enters all the letters of the alphabet using the template gestures. By the time the user enters a gesture prototype automatically suggests the most frequent letters using the Naïve Bayes classifier. |

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.
