Ask HN: What is the best way to get attention of VR early adopters?

We are working on VR app that we think will change the way people interact via immersive communication on-the-go. We want to genuinely build a audience that cares about the problem of immersive communication. We think our target audience is between age 15-30 yrs as they care about better communication. Since we are not competing with HMD or Magic Leap etc we don't really think HMD market should be our target market. We want to cater to people who want to have better communication capabilities. Since this is consumer, it is slightly harder to nail and segment down the target market. Any ideas on how to build a audience or gather people around the problem we are trying to solve. We are writing Blogs/content marketing, doing social media, talking to friends but we haven't yet found traction in people who would benefit the most.
