Abstract | A key to optimize a user's entertainment or learning experience when playing interactive games is to understand his emotional responses. Current methods mostly exploit intrusive physiological signals to detect a player's emotions. In this study, we proposed a method to detect a player's emotions based on heart beat (HR) signals and facial expressions (FE). In this work, a continuous recognition of HR and FE through videos captured by Kinect2.0 is conducted considering the continuous perception of the human emotion. Bidirectional long and short term memory (Bi-LSTM) network is used to learn the HR features, and convolutional neural network (CNN) is trained to learn the FE features. To further meet the demands for real-time, the SOM-BP network is employed to fuse the HR and FE features, which can perfectly recognize the player's emotion. Experimental results demonstrate our model has high accuracy and low computation time for four emotions of “excitement”, “anger”, “sadness” and “calmness” in different games. Moreover, the emotion's intensity can be estimated by the HR value. |

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.
