+
+IHear: Mobile Application for Hearing Impaired children to facilitate their hearing and speech capabilities.
+Main Objective - The primary objective of this research is to develop a user-friendly and engaging learning application that empowers speech and hearing-impaired children aged 6-10 years. 
+
+Main Research Questions-How to help hearing impaired children in knowledge gathering?
+
+IT20149758 -Koralage H.C
+
+Individual Research Question - How to facilitate hearing - impaired students ability to identify sounds?
+Individual Research Objective - To develop a sound classification function that helps children aged 6-10 identify noises around them and incorperating the learning aspect to it.​ 
+
+IT20075712 -G.N.J.Liyanage
+
+Individual Research Question -How to develop a game for hearing screening ?
+Individual Research Objective -Develop a effective  hearing screening method for Identifying hearing stages of children. 
+
+IT20468460 - M.H.M.I.D.Mapa
+
+Individual Research Question - How can sound amplification help for hearing impaired persons for the user?
+Individual Research Objective - It would allow customizing amplification of verbal soundtrack and live transcription option with saving and downloading the transcription.
+
+IT20024604  - Senanayake S.V.M
+
+Individual Research Question -.How do hearing-impaired children interact with video games, and what are their preferences and needs in terms of accessibility features?
+Individual Research Objective - To investigate the impact of incorporating accessibility features in video games on the gaming experience, cognitive and verbal development, and social inclusion of hearing-impaired children.
