Subtitle data is included in most movies, but cinemas in New Zealand rarely use it, so cinematic options for the hearing-impaired are extremely limited.
One of the changes was finding a way to make the subtitles stay in place when people turned their heads, to talk to their neighbour, for instance.
The subtitles would follow the user, which can be annoying and distracting.
While their current prototype involved customising off-the-shelf headsets, they plan to build headsets from scratch, make them more aesthetically pleasing and lighter.
