File this under speculation but recent information about a 'Surface Dial' and patents were revealed this morning in addition to Surface Studio. While the latter makes sense for an all-in-one Surface PC, many heads are scratching on what 'Surface Dial' could be.

A few weeks ago, Leon Zandman found references in the Windows 10 code for a radial controller that "can be paired and has haptics" for feedback. Twitter user WalkingCat posted some of the references as well speculating RadialController could be the software for Surface Dial.

Interestingly, back in June, Christian Jolicoeur tweeted an image of his Windows 10 Settings following an Insider update. The image references settings for 'Wheel' under Devices that are usually paired with a PC e.g. Mouse, Printers, Bluetooth, etc. The description of the app says:

Use the wheel with your left hand and the pen with your right hand

There is also a toggle for Vibrate i.e. the haptic feedback references noted above.

Could this be the Surface Dial?

Christian goes on to speculate that maybe this device is similar to Wacom's Express Key Remote, which has "17 customizable buttons" and a "Touch Ring" that "allows for instant one-touch access to timesaving shortcuts in all your favorite creative applications." That device is primarily aimed at graphics professionals and acts like a handheld shortcut for frequently used features.

Putting all those clues together and it seems as if Surface Dial is a handheld device for an artist to streamline their actions. The Wacom express Key Remote retails for $99, and that seems in line with what Microsoft would charge for a similar feature for its Surface line, including that new Studio-centric PC.

This information also meshes with the Surface Mouse and two Surface Keyboard desktop accessories already discovered.

Of course, with just two days lefts all should be made clear very soon.
