I'm helping a startup to build entertaining content for Mobile VR. It should perfectly be adopted by airlines and hospitals for example, where people are physically isolated. Asking for more opportunities experts from other industries might see.
VR has a vast application across all the sectors in the Global market. Entertainment is a basic need of humans, therefore there is a huge spending of a common household income that goes out for entertainment. I would recommend you to target the untapped segments and get an early mover advantage.
I will be happy to brainstorm with you if needed.
