Jared developed this tool for people who frequently gave demonstrations of HoloLens at hackathons and conferences. It served two purposes:
- Replicate the opening screen of the Calibration app, which helps users make sure they’ve positioned the device correctly.
- Allow the IPD to be set quickly using a voice command instead of needing a companion PC or the Device Portal.
While no longer necessary for HoloLens 2, this project still demonstrates how to “loop back” to the device portal from a Unity app running on the device. (Source)
