Solution Overview

Problem

Existing screensavers are static and do not dynamically adapt to user preferences or provide personalized and interactive content.

Innovation Solution

A system and method for dynamically modifying screensavers by injecting personalized and interactive content using an object injection engine that replaces off-screen portions of the screensaver with new objects, which are selected based on user information and preferences, and can include interactive elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screensavers are made static and simple, then device complexity is reduced, but adaptability and personalization capability deteriorate

Engineering Contradiction:
Improvepersonalization capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The screensaver is divided into multiple panels that can be independently modified. Each panel can contain different objects that are separately replaceable, allowing personalized content to be injected into specific regions without affecting the entire screensaver structure. This segmentation enables gradual personalization while maintaining system manageability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Replacement objects are prepared and injected into off-screen panels before they are displayed. The object injection engine pre-loads personalized content into the panel buffer during periods when those panels are not visible, so that when panels rotate into view, the personalized content is already in place. This preliminary action enables dynamic personalization without causing display interruptions or noticeable delays.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If screensavers are made dynamic with frequent updates, then personalization and user engagement improve, but loss of time for content loading and processing increases

Engineering Contradiction:
Improvedynamic content update capabilityVSAvoidcontent loading time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary injection of replacement objects into off-screen panels during periods when those panels are not displayed. By preparing personalized content in advance during idle periods or when panels are hidden, the system eliminates loading delays during active display, maintaining both dynamic content updates and smooth user experience.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The screensaver employs rotating panels that periodically bring different content into view. This periodic display pattern creates natural opportunities to inject and update content in panels that are currently off-screen, allowing the system to refresh personalized content at regular intervals without interrupting the user experience during active display periods.

Inventive Principle:
Principle #19Periodic action

3Adaptability or versatility

If replacement objects are injected during active display, then real-time personalization is achieved, but display stability and visual quality deteriorate

Engineering Contradiction:
Improvereal-time update capabilityVSAvoiddisplay stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

All replacement object injections are completed in advance during off-screen periods before panels are brought into view. This preliminary preparation ensures that when personalized content is displayed, it is already fully loaded and rendered, eliminating any potential display instability, flickering, or visual artifacts that would occur during active content replacement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The off-screen panel buffer serves as an intermediary between the content injection system and the display output. Personalized objects are injected into this intermediate buffer zone where they can be prepared and validated without affecting the active display. Once ready, the entire panel (including injected objects) is atomically swapped into view, ensuring display stability and preventing partial or corrupted rendering.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If more panels are used in the screensaver, then personalization coverage and content variety improve, but device complexity and processing requirements increase

Engineering Contradiction:
Improvecontent coverageVSAvoidpanel management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The screensaver is divided into multiple independent panels, each capable of containing and displaying personalized objects. This segmentation allows the system to distribute personalized content across multiple regions, increasing overall personalization coverage without requiring complex full-screen rendering. Each panel can be independently managed, injected, and updated.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The object injection engine implements a universal interface for injecting replacement objects into any panel. The same injection mechanism and object management system handles all panels uniformly, regardless of their position or content type. This universal approach enables scalable panel management where adding more panels does not proportionally increase system complexity, as the injection logic remains constant and reusable across all panels.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for dynamically adjusting a screensaver on a display device. An example embodiment operates by a media device detecting the initiation of a screensaver and requesting replacement objects to be injected into the screensaver while the screensaver is displayed on a display device. The media device may receive the replacement objects, select which replacement objects to be injected into the screensaver, and injecting the selected replacement objects into an off-screen portion of the screensaver prior to the off-screen portion being displayed on the displayed device.
