The latest preview build for Microsoft HoloLens is packed with new sharing features including support for the Miracast protocol.
In the Insider Preview RS5 for the Windows 10 April 2018 update, Miracast allows mirroring their view of a nearby Surface device or TVs and monitors with a Microsoft display adapter. To enable the feature, users can select "Connect" from the "Start" menu and then select the target device.
Sharing is a recurrent theme with the bleeding release. In addition to Miracast support, the release includes the Windows Share Sharing feature, which lets you send photos, videos, and other sharable content to other Windows devices. By integrating a Share button in Microsoft Edge, HoloLens users can share Web content.
The rest of the new features that HoloLens provides via Insider Preview fall into the UI category. The release includes a new notification interface similar to the PC format that allows users to view and respond to alerts. The preview also includes a load indicator for the boot process so that users can see the progress.
Users can also find it easier to control video capture by holding the Pause Video command to the Start menu and Add Quick Actions menus next to the Start Video button. Finally, the HoloLens get new visual overlays, such as keyboard, dialogs and file selection in immersive apps, as well as indicators for volume changes.
The update also adds a few new developer toys, including support for the Camera Capture UI API, which enables camera functionality within an app, and Mixed Reality Capture enhancements. The preview build also brings an improvement in the quality of life for commercial and international users.
With a new HoloLens reportedly coming out next year, Microsoft was surprisingly active with HoloLens updates after the end of 2017 without a single update. Microsoft has now released its second update for 2018, having arrived with RS4 in March. If the new HoloLens actually arrives in the first quarter of 2019, this could be the last HoloLens update to date.
