Mix View was supposed to go hand-in-hand with Nokia's McLaren smartphone . That phone had a 3D Touch interface letting users hover their finger over the display. The virtual push gesture would cause certain tiles to then 'explode' into smaller tiles with more user information. Some of the design influence came from the Zune era of design but combined with some very advanced gesture detecting hardware.

The feature was later to be called Mix View, and it just got published with the United States Patent and Trademark Office. Interestingly, the application was filed just a few months before our report in August 2014, and the filing was just published today.

In December 2014, we reported that Microsoft was working to bring an 'exploding tile' paradigm to the Windows 10 operating system. The user interface feature would make a Live Tile explode into small tiles with information provided from the app.

McLaren was cancelled in July 2014 due to hardware issues and other project failures. This decision at the time sealed the fate for the high-end Lumia portfolio as that phone was the next flagship.

In today's publishing patent filing we can see some of the ideas behind the design as well as possible implementations. The filing is full of technical jargon as expected:

"The user interface includes a concurrent display of a plurality of representations of applications that are selectable by a user to launch respective applications. Gesture-based techniques can be used to interact with an application representation to cause one or more visible targets to appear adjacent the representation. The individual targets are individually associated with some type of application functionality, e.g., a quick action or a deep link into content associated with the application. An individual target can then be selected, e.g., touch-selected, by a user to initiate the associated functionality."

Regarding hardware usage:

"In one or more implementations, a computing device includes one or more modules implemented at least partially in hardware. The one or more modules are configured to output a user interface for display. The user interface includes a concurrent display of a plurality of representations of applications that are selectable by a user to launch respective applications."

And a more concrete example of the idea in action:

"For example, the representation may be configured as a tile that includes a plurality of targets (e.g., sub-tiles) that are user-selectable. The user-selectable targets are configured such that selection by a user causes access to corresponding functionality of the application and in this way may provide a "deep link" to various functionality of the application. The tile, for instance, may include a user-selectable target to navigate to a root level (e.g., welcome screen) of the application, e.g., a start screen of a weather application. Other user-selectable targets may be utilized to access other application functionality, such as weather at different geographic locations. In this way, a user may directly access different parts of an application directly from the representation of the application that launches the application. A variety of other examples are also contemplated, further discussion of which may be found in relation to the following sections."

This filing accurately matches our description of Mix View from our December 2014 report. In fact, there was even a Nokia SDK for developers that let them design and test such implementations for Windows Phone. However, the SDK and project were presumably scrapped with Nokia's McLaren.
