A custom Steadicam system was developed to track and display what a HoloLens device sees in real-time, requiring multiple sensors and data feeds transmitted over a single tether.
The system combines a RED Dragon camera, HoloLens optics, and an Xbox Kinect depth sensor on a single rig, with output processed and overlaid with holographic content at a half-second delay.
The transmission system requires 3G SDI video output and return signals along with optical Thunderbolt, single-mode fiber, sync signals, and power, necessitating a thick cable bundle from operator to sled.
Initial demonstrations were limited to 25 feet of tether distance due to 3G SDI bandwidth constraints, with the server processing equipment positioned nearby.
Extending range to 100 feet was achieved by converting SDI signals to multimode fiber with media converters powered by a portable USB battery pack worn by the operator.
Sled-mounted power solutions must use voltage-regulated converters to prevent disruption to sensitive onboard electronics.
The operator used a PRO/XCS Steadicam sled with Cinetronic monitor and relocated the cable harness from a shoulder tether to a shoulder-mounted configuration to reduce steering strain.
MegaFlex SDI cables and fiber optics were used to minimize bundle size while maintaining necessary signal integrity over extended distances.

The exact specifications and construction details are proprietary and confidential to Microsoft.
The operator cannot share photographs or detailed technical schematics of the system.
The setup was specifically engineered for demonstration purposes and may not be reproducible without access to the specialized components and engineering support.
These systems represent experimental technology from the early stages of HoloLens development and may not reflect current commercial implementations.
