Windows 10 update and Surface Studio PC unveiled
New 3D creation and editing tools are being added to the next edition of the Windows 10 operating system, including a revamped version of Paint.
The firm also revealed a range of new virtual reality headsets to encourage users to interact with their creations.
One expert said the moves would help prepare consumers for more radical augmented reality features, which are still under development.
Microsoft also unveiled its first all-in-one desktop, the Surface Studio.
It features what is said to be the thinnest ever LCD touchscreen and has an accompanying dial controller, which can be placed directly on the display or used at its side.
An on-stage demonstration of the 3D Paint application showed how a stylus could be used to draw 2D-graphics that were automatically given depth by the software. Photographic elements could also be added to the design, and parts could be animated.
To create 3D models of real-world objects, Microsoft said it was developing a smartphone app that works by waving the handset around the desired item.
The finished creation can be added to Powerpoint presentations, shared on Facebook and other online sites or placed within a virtual reality environment.
"VR is hot with consumers at the moment, and Microsoft is making sure it is not missing the boat from an ecosystem perspective and leaving it all to Google," said Carolina Milanesi, a consumer tech analyst at Creative Strategies.
"3D also resonates with consumers. Focusing on creating content and sharing that content is a good way to have them start to think about mixed-reality, preparing them for the HoloLens headset."
Microsoft revealed Acer, Asus, Dell, HP and Lenovo will manufacture new Windows 10-compatible virtual reality headsets, which fill the wearer's view with computer-powered images.
It said the lowest-cost model would be $299 (£245). That is several times cheaper than the video games-focused Oculus Rift and HTC Vive headsets already on sale.
They offer a staging post until the firm launches a consumer edition of its HoloLens headset. The kit superimposes graphics over real-world views, moving them in turn with the wearer's head movements so that they appear to be part of the environment.
Versions of the HoloLens are already on sale, but cost between £2,719 and £4,529, and are currently targeted at developers.
The Creators Edition of Windows 10 is due for release early next year and will be provided as a free upgrade for computers already running the software.
Its other new features include:
- a bar of icons showing the user's closest friends, family and other acquaintances, which brings together chats, emails and other communications in a single place
- a way to make emojis and user-generated 3D objects pop up on friends' desktops
- the ability to receive SMS text messages on the PC if the user owns an Android phone
- the chance to set up and host customised video games tournaments featuring other players on Windows 10 and Xbox
Microsoft began the final stretch of its New York event by unveiling a new laptop, the Surface Book i7, which it said offered twice the graphics power of the last model and up to 16 hours of battery life.
But it dedicated most of the section to the new Surface Studio desktop computer.
The machine features a touchscreen held to a box below by two adjustable chrome arms.
Microsoft claims the display is "best in class".
Its 192 pixel-per-inch resolution is slightly lower than that of the top-end iMac. But it compensates for this by being an inch larger than Apple's model, as well as appearing to be substantially thinner thanks to most of the machine's guts being placed at its base.
The PC is sold with a wireless mouse, keyboard and stylus, but is distinguished by a fourth peripheral: the Surface Dial.
This can be spun to carry out functions such as skimming through colours, adjusting the volume or flipping through pages.
It provides vibration-based feedback as it is used. And when placed on the screen, it brings up a graphical interface within compatible software, providing the user with a new way to select from commands.
"Surface Studio won't be the highest-performance all-in-one system," commented Patrick Moorhead, an analyst at Moor Insights & Strategy.
"Microsoft played it safe with sixth-generation Intel processors, mobile graphics and USB 3 ports.
"But it should meet the needs of most creative experts - the intended target market - and is priced for [users] who want something very cool and unique."
Surface Studio will cost between $2,999 and $4,199 (£2,452 and £3,433) when it goes on sale in the US on 15 December.
Although Microsoft has had some success with its earlier Surface line-up, wider sales of PCs and tablet computers are experiencing their second consecutive year of decline.
The consultancy Gartner has forecast that after an 8.7% fall this year, sales will see a smaller dip in 2017, and then return to growth again in 2018.
