Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In extended reality (XR) systems with video pass-through electronic devices, users may lose direct view of their physical setting due to low battery or system failures, particularly when the device blocks the user's line of sight.

Innovation Solution

Implementing structured-shutdown-mode versions of the video view, which reduce power consumption and processing resources, allowing the device to continue providing a view of the physical setting even in low power or failure states. This includes transformations such as projecting the video feed onto a predefined surface and discontinuing warping or filling operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the device processes video feed with full warping and filling operations to provide a complete video view, then the video view quality is maintained, but the power consumption rate increases

Engineering Contradiction:

Improvevideo view qualityVSAvoidpower consumption rate

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by implementing structured shutdown modes that selectively maintain only essential video feed processing functions while suspending non-essential operations like warping and filling. This allows the system to provide a basic video view at reduced power consumption during low battery states, rather than maintaining full processing quality.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system dynamically changes processing parameters based on battery state, transitioning from full processing mode to structured shutdown modes. This involves adjusting the level of video feed processing (from complete warping/filling to basic display only) according to available power, thereby optimizing the balance between video view quality and power consumption rate.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the device continues full video processing in low power state, then the video view quality is maintained, but the device may fail completely sooner

Engineering Contradiction:

Improvedevice operational continuityVSAvoidpower consumption rate

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements beforehand cushioning by preparing structured shutdown modes in advance that can be activated when battery levels drop. These pre-configured fallback processing modes ensure that the video feed functionality continues with reduced processing, cushioning against complete device failure and maintaining operational reliability during low power states.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system dynamically adjusts video processing operations based on real-time battery state. It transitions from static full processing mode to dynamic structured shutdown modes that adapt processing intensity to available power, thereby extending operational continuity and improving reliability during low power conditions.

Inventive Principle:

Principle #15Dynamics

3Measurement precision

If the device performs complete video feed processing including warping and filling, then the video view accuracy is maintained, but the processing resource consumption increases

Engineering Contradiction:

Improvevideo view accuracyVSAvoidprocessing resource consumption

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent applies partial action by selectively maintaining only the essential video feed display function while suspending computationally intensive operations like warping and filling during structured shutdown modes. This reduces processing resource consumption while preserving the core functionality of providing a video view of the physical setting.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The subject technology provides structured-shutdown-mode versions of a video view of a physical setting of an electronic device. An electronic device may provide, at a first power consumption rate, a video view of a portion of the physical setting, the portion being physically blocked from being directly viewed by a user of the device, by the electronic device itself. Structured-shutdown-mode versions of a video view may be provided, at a second power consumption rate lower than the first power consumption rate, to a display of an electronic device when the device determines that it is in a low power or failure state. In this way, the electronic device can reduce the functionality and power consumption of the display in a structured manner, to continue to provide a version of the video view to the user in the low power or failure mode state.
