Solution Overview

Problem

Devices with display capabilities, such as smartphones or tablets, face challenges in optimally outputting content when a picture-in-picture user interface is used, as the secondary window may obscure important content or require capabilities beyond the device's technical limitations.

Innovation Solution

The system detects conditions such as device capabilities, user input, and gaze direction to move content from a first device to a second device with better output capabilities, ensuring optimal viewing and audio experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a picture-in-picture user interface is used to enable simultaneous consumption of multiple content, then user convenience is improved, but the secondary window may obscure important content or exceed device output capabilities

Engineering Contradiction:
Improveuser convenienceVSAvoidcontent obscuration
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent extracts the secondary content window from the first device's display and relocates it to a second device with superior output capabilities. This separation allows the primary device to maintain full visibility of important content while the secondary device handles the picture-in-picture content, eliminating the obscuration problem while preserving user convenience.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If picture-in-picture window is displayed on the first device, then continuity of content consumption is improved, but device output capabilities may be insufficient

Engineering Contradiction:
Improvecontent consumption continuityVSAvoidoutput capability sufficiency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system introduces a second device as an intermediary to handle the picture-in-picture content output. This mediator device possesses the required output capabilities (such as audio output or enhanced display capabilities) that the first device lacks, thereby enabling continuous content consumption without being constrained by the first device's limited output capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the second window overly the first window in picture-in-picture mode, then simultaneous content access is improved, but important content visibility deteriorates

Engineering Contradiction:
Improvecontent access efficiencyVSAvoidcontent visibility
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent transitions the picture-in-picture content from a two-dimensional overlay on the same display to a separate spatial dimension by moving it to a different device. This dimensional shift allows both content windows to be fully visible simultaneously - the first content on the primary device and the second content on the secondary device - eliminating the visibility loss while maintaining efficient content access.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

This specification describes an apparatus, method and computer program for output of content from a first device to a second device. The apparatus may comprise means for: outputting, on first device, a user interface comprising a first window associated with first content and a second window associated with second content, the second window at least partly overlying the first window and detecting one or more predetermined conditions associated with the user interface. Responsive to detecting the one or more predetermined conditions, the apparatus may be configured to move output of at least part of the first content or at least part of the second content from the first device to a second device which is linked to the first device.
