Over 5% of the world’s population – or 466 million people – have disabling hearing loss. It is estimated that by 2050 over 900 million people – or one in every ten people – will have disabling hearing loss (WHO). Communication among the deaf community is predominantly through the medium of sign language. One of the key challenges on the community is to have independent access to information. Individuals with profound hearing loss or deafness are predominantly reliant on sign language and text/visual based communication methods of interaction. This use case focuses on developing an innovative solution to alert individuals with profound hearing loss or deafness about relevant information during emergency situations while commuting in public transport systems.
