Solution Overview

Problem

Existing augmented reality (AR) devices face challenges in efficiently translating sign language due to resource management limitations, particularly in processing power and computational load, which can lead to inefficiencies and increased power consumption.

Innovation Solution

A collaborative system of AR devices, where one device captures hand gestures and another performs computational-intensive tasks like hand tracking and gesture recognition, distributing processes to optimize resource utilization and reduce power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a single AR device performs all sign language translation processes locally, then translation speed is improved, but power consumption and computational load increase

Engineering Contradiction:
Improvetranslation speedVSAvoidpower consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent divides the sign language translation system into multiple functional segments distributed across different AR devices. One device captures hand gestures while another performs computational-intensive tasks like hand tracking and gesture recognition. This segmentation allows each device to perform only its designated function, reducing overall power consumption while maintaining translation speed through coordinated operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a collaborative framework where AR devices act as intermediaries to each other. Instead of one device bearing the entire computational burden, devices coordinate by capturing, sharing, and processing visual data together. This intermediary collaboration distributes the computational load and reduces individual device power consumption while achieving real-time translation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If computational-intensive tasks are performed on a single device, then translation accuracy is improved, but device complexity and resource requirements increase

Engineering Contradiction:
Improvetranslation accuracyVSAvoidcomputational resources
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments complex computational tasks across multiple devices. Hand tracking is performed by one device while gesture recognition and translation are handled by another. This division maintains translation accuracy by ensuring each device focuses on its specialized function rather than attempting to perform all processing locally, thereby reducing individual device complexity requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges the capabilities of multiple AR devices into a unified collaborative system. By combining the computational resources of multiple devices working together, the system achieves translation accuracy that would require excessive resources on a single device, while distributing the actual computational burden across the network.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of time

If all processing is done locally on the AR device, then response time is reduced, but energy efficiency deteriorates

Engineering Contradiction:
Improveresponse timeVSAvoidenergy efficiency
Core Design Contradiction:
Loss of timeVSLoss of energy

Solution Approach 1:

The patent segments processing tasks and assigns them to different devices based on their capabilities and current workload. Simple tasks like hand gesture capture are performed locally with minimal processing, while energy-intensive tasks are offloaded to collaborating devices. This segmentation maintains fast response times through coordinated processing while significantly improving overall energy efficiency by avoiding redundant computations on a single device.

Inventive Principle:
Principle #1Segmentation

AI summary

A method for recognizing sign language using collaborative augmented reality devices is described. In one aspect, a method includes accessing a first image generated by a first augmented reality device and a second image generated by a second augmented reality device, the first image and the second image depicting a hand gesture of a user of the first augmented reality device, synchronizing the first augmented reality device with the second augmented reality device, in response to the synchronizing, distributing one or more processes of a sign language recognition system between the first and second augmented reality devices, collecting results from the one or more processes from the first and second augmented reality devices, and displaying, in near real-time in a first display of the first augmented reality device, text indicating a sign language translation of the hand gesture based on the results.
