REDMOND, Wash. | Microsoft has taken the wraps off a new version of Windows — and a new wearable 3D gadget it calls the HoloLens.

The HoloLens is worn over the eyes like virtual reality headsets. While it’s unclear when it might be available for sale, a Microsoft engineer showed how it could be used to view and edit three-dimensional renderings of people, machines or other objects.

The new gadget runs on the newest version of Microsoft’s flagship operating system, Windows 10, which the company says is designed to provide a more familiar experience as users shift back and forth between personal computers to tablets, smartphones and other devices, including gaming consoles.

Microsoft says Windows 10 will come with a new web browser and bring its voice-activated digital assistant, Cortana, to personal computers.
