At the end of the day, you are asking someone to put something on their face that is still very different ergonomically than glasses (and I’m not sure even glasses would overcome enough friction). The ROI has to overcome the business (or personal) friction of buying the hardware, the friction of the form factor plus any friction from changed workflows.
Now put that in an operational workflow instead of training and the risks go up. Most are still skeptical of device reliability (not to say there aren’t suitable devices for operational roles but the perception is still a hurdle, and the applicability is often device-specific). Now add on to that limited experience with devices (many decision makers have never put one on), added security complications, specialized software development skills, limited content libraries and very real accessibility concerns and a lot of enterprises can never get past an “innovation center demo.”
For many industries the value proposition just isn’t there yet. But that said, I’d recommend digging a little deeper as there’s a lot of existing use-cases and deployments, both failed and successful, outside of IVAS.
