An expanding attention regarding human emotion is a pressing motive towards the current research in neuroscience and artificial intelligent. People need to communicate by exchanging information through verbal or nonverbal communication via sound, visual gestures (facial expression or hand/body gestures). In today’s society, digital multimedia is one of the essential elements in daily life activities that can emphasize communication and emotions adequately. People with severe motor disabilities have difficulties in communicating and showing their emotions directly. Therefore, brain computer interface (BCI) can be a helpful tool as an alternative and assistive communication tools for sharing emotional information. This paper has conducted a review analysis to present the current trend in using digital multimedia to express the human feelings for the latest five years. Twenty-nine studies were selected from IEEEXPlore, PubMed and ScienceDirect, and classified into three major categories: methodology, multimedia type and number of emotion classes. The results show the need for more case studies and games in this area. There is also a need to increase the quality and quantity of research in emotion using the electroencephalography (EEG).
