Content object layering for user interfaces

A computing device comprising:

• a processor;
• and
• memory comprising processor-executable instructions that when executed by the processor cause performance of operations, the operations comprising:
• defining a z-axis for a user interface;
• defining a set of layers along the z-axis;
• ranking a set of content objects, wherein the ranking comprises ranking a first content object higher than a second content object based upon the first content object being designated a transient content object and the second content object being designated a permanent content object;
• assigning one or more content objects of the set of content objects to layers of the set of layers based upon the ranking;
• rendering the user interface on a display of the computing device, wherein content objects within layers below a current layer are not displayed;
• in response to receiving user input for a content object within the current layer, modifying the user interface to display the first content object within a first layer positioned below the current layer along the z-axis;
• defining a bottom layer along the z-axis below the set of layers;
• in response to receiving second user input comprising a swipe gesture in a first direction across at least some of a third content object, within a second layer, displayed in the user interface, modifying the user interface to transition from displaying the third content object to displaying a fourth content object within the bottom layer;
• in response to receiving third user input comprising a swipe gesture in the same first direction across at least some of the fourth content object within the bottom layer, modifying the user interface to transition from displaying the fourth content object to displaying the third content object within the second layer;
• and
• in response to receiving fourth user input comprising a swipe gesture in the same first direction across at least some of the third content object within the second layer, modifying the user interface to transition from displaying the third content object to displaying another content object within another layer positioned above the second layer along the z-axis.

A non-transitory machine readable medium having stored thereon processor-executable instructions that when executed cause performance of operations, the operations comprising:

• defining a z-axis for a user interface;
• determining a number of layers based upon a network bandwidth associated with the user interface;
• defining a set of layers, with the number of layers, along the z-axis;
• determining a set of content objects based upon at least one of a current location of a first device, a time of day, or a determination that the set of content objects have representations in a first interface;
• ranking the set of content objects based upon display criteria defining an ordering for which content objects are to be displayed, wherein the ranking comprises one of:
• ranking a first content object higher than a second content object based upon the first content object more closely matching a search performed using the user interface than the second content object;
• or
• ranking the first content object higher than the second content object based upon the first content object being designated a transient content object and the second content object being designated a permanent content object;
• assigning one or more content objects of the set of content objects to layers of the set of layers based upon the ranking;
• rendering the user interface on a display of a computing device, wherein content objects within layers below a current layer are not displayed;
• in response to receiving a first user input for a content object within the current layer, modifying the user interface to display the first content object within a first layer positioned below the current layer along the z-axis;
• and
• in response to receiving a second user input for the first content object, modifying the user interface to display a flip animation of the first content object from a front side of the first content object to a back side of the first content object.
