Abstract: One variation of a method for quantifying user engagement includes: serving a digital advertisement to a mobile device; recording a first proportion of pixels of the digital advertisement rendered on a display of the mobile device during a first sampling period; recording a second proportion of pixels of the digital advertisement rendered on the display of the mobile device during a second sampling period offset in time from the first sampling period; calculating a cumulative pixel exposure of the digital advertisement at the mobile device based on a combination of a first product of the first proportion of pixels and a duration of the first sampling period and a second product of the second proportion of pixels and a duration of the second sampling period; and storing the cumulative pixel exposure as an engagement metric for a user consuming the digital advertisement at the mobile device.

Abstract: One variation of a method for serving interactive ad content includes, in response to a pause event that pauses playback of a digital video, viewed on a display of a streaming device accessed by a user: overlaying the digital video with a home screen including an image player and a set of icons linked to a set of video advertisements; in response to a first user input proximal an icon, in the set of icons, corresponding to a video advertisement, in the set of video advertisements, reconfiguring the image player and initiating playback of the video advertisement within the image player; during playback of the video advertisement, in response to a second user input proximal the icon, expanding the image player and activating an audio stream of the video advertisement; and, in response to a user input that resumes playback of the digital video, pausing playback of the video advertisement.

Abstract: One variation of a method for serving interactive content to a user includes, at a visual element inserted into a document accessed by a computing device: loading a first frame from a digital video; in response to a scroll-down event that moves the visual element upward from a bottom of a window rendered on the computing device toward a top of the window, seeking from the first frame through a subset of frames in the digital video in a first direction at a rate corresponding to a scroll rate of the scroll-down event, the subset of frames spanning a duration of the digital video corresponding to a length of the scroll-down event; and, in response to termination of the scroll-down event with the visual element remaining in view within the window, playing the digital video forward from a last frame in the subset of frames in the digital video.

Abstract: One variation of a method for aggregating advertisement interaction data includes: receiving a ping from a visual element loaded onto a mobile device, the ping containing: a timestamp; and a value representing a proportion of the visual element visible in a viewport at the mobile device; in response to the value exceeding a threshold value, grouping the ping with a group of pings in a ping feed, the group of pings containing a unique identifier associated with the mobile device; in response to the value falling below the threshold value, concluding an advertisement view session containing the group of pings; calculating a time spent value for visibility of advertisement content in the visual element within the advertisement view session based on timestamps of pings in the group of pings; outputting an advertisement view session packet containing the unique identifier and the time spent value to a database.

Abstract: One variation of a method for serving interactive advertisement content includes, at a visual element rendered within a window of a computing device: loading an interactive advertisement, including a digital advertisement and a mask overlaid the digital advertisement, into the visual element, the mask including a base layer and an aperture defining a second opacity less than a first opacity of the base layer; in response to a scroll event that moves the visual element a first position within the window, rendering the interactive advertisement within the visual element; and, in response to a scroll event that moves the visual element to a second position within the window, transforming the mask according to a sequence of transformations at a rate proportional to a scroll rate of the scroll event, the sequence of transformations corresponding to a sequence of vertical positions of the visual element within the window.

Abstract: A variation of a method for serving interactive content includes: inserting a parent card into a visual element; inserting a set of child cards over the parent card in the visual element, each child card including advertising content related to the parent card; in response to a swipe over the visual element following insertion of the visual element into a document rendered on a display, indexing through the set of child cards rendered over the parent card; in response to selection of a child card, triggering the computing device to open an expanded window over the document; rendering expanded variants of child cards within the expanded window; in response to a swipe over the expanded window, indexing through expanded variants of the set of child cards rendered; and, in response to selection of an expanded variant of a particular child card, triggering the computing device to navigate to an external document associated with the particular child card.

Abstract: One variation of a method includes: rendering a home screen of an ad stream viewed on a display of a streaming device accessed by a user, the home screen including an image player located in a first subregion of the home screen and a set of icons selectable by the user, each icon corresponding to a video advertisement loaded within the image player; in response to detecting a first user input proximal a first icon, reconfiguring the image player to a second subregion of the home screen and triggering playback of a first video advertisement within the image player; and, during playback of the first video advertisement, in response to receiving a second user input proximal the first icon, reconfiguring the image player to a third subregion of the home screen, activating an audio stream corresponding to the first video advertisement, and continuing playback of the first video advertisement.
