A tutorial video called "Steam Frame Welcome Tour" was recently exposed on Reddit, showing the software interface of Valve's upcoming VR headset to the outside world for the first time. Although the source of the video is unclear, the community generally believes that the material is highly credible.

The video, purportedly recorded using Valve Index, appears to be the initial boot process users will see when setting up a Steam Frame headset for the first time.

The video exposed this time provides the most detailed preview of the Steam Frame software interface to date. The overall interface is obviously built on the experience of SteamOS and Steam Deck, and is very similar to Steam's familiar "big screen mode". The video shows part of the process of setting up the controller, as well as instructions on how to call out and close the interface. One noteworthy detail is that a prompt pops up in the system asking "Do you want to connect the VR headset to the PC?" This further confirms previous speculation: Steam Frame will support stand-alone running mode without the need to always be connected to a computer.

Interestingly, in parts of the tutorial's interface, Steam Frame still uses its old codename "Deckard" - a name that has been floating around in various leaks and data mines for years. Additionally, placeholder text and unfinished UI elements can be seen in the video, indicating that the software is still under development.
While the video doesn't reveal any major new information, it provides the first visual look at the software for Valve's new VR headset. Valve has previously confirmed that both Steam Machine and Steam Frame are scheduled to be officially released this summer.
