Hi @msawtell and thanks for your query. This forum is principally intended for support with the Tobii Tech range of eye trackers (4C, EyeX, Alienware laptop, etc) and the associated SDK’s (Core SDK, Stream Engine API, etc)
The Tobii Pro HMD is part of the Tobii Pro Business department so I would encourage you to reach out to their own dedicated support department @ http://www.tobiipro.com/contact/contact-support/ for an answer to your query.
I am quite sure however that there will be a real time feedback software available to view the gaze data simultaneously on another system but the team at Tobii Pro can confirm this.
Apologies for any inconvenience and best of luck in finding a resolution.
