Solution Overview

Problem

AR glasses with limited battery life and high energy consumption pose challenges in providing a seamless mixed reality experience for extended reading sessions, particularly when interacting with printed codes in books and other reading materials.

Innovation Solution

Implement a reading mode that puts AR glasses into a sleep state at intervals to conserve battery life and manage code module downloads efficiently, reducing energy consumption by downloading modules in advance and using low-energy communication protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If AR glasses continuously monitor and process reading materials to provide mixed reality experience, then user experience is improved, but battery life is depleted quickly

Engineering Contradiction:
Improvemixed reality experienceVSAvoidbattery life
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The system implements periodic monitoring by capturing images at predetermined time intervals rather than continuously. The processor is activated at specific intervals to detect codes in captured images, allowing the AR glasses to maintain enhanced reading functionality while significantly reducing power consumption compared to continuous operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system pre-loads code modules into memory before they are needed for execution. By anticipating which codes may be encountered during reading and preparing their corresponding modules in advance, the system reduces real-time processing requirements and energy consumption while maintaining seamless mixed reality experience.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If AR glasses download code modules in real-time when codes are detected, then code availability is ensured, but energy consumption increases

Engineering Contradiction:
Improvecode availabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system pre-loads code modules into memory before they are needed for execution. By anticipating which codes may be encountered during reading and preparing their corresponding modules in advance, the system reduces real-time processing requirements and energy consumption while maintaining seamless mixed reality experience.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates local copies of code modules in the AR glasses' memory, eliminating the need for repeated real-time downloads during reading. This local storage approach ensures code availability while minimizing communication energy expenditure.

AI summary

Systems, methods, and computer readable media for enhanced augmented reality (AR) reading are provided, where the methods include entering a reading mode, capturing an image of a section of reading materials such as a page of a book, identifying a code within the image, and identifying a code module corresponding to the code. The methods further include executing the code module, the code module providing an augmented reality object or virtual reality object related to an object depicted on the section or page, entering a sleep mode for a sleep duration based on an estimated reading time duration of a section or page, awaking after the sleep duration, and capturing a next image. The sleep duration is adjusted based on times when identifiers of the sections of the reading materials such as numbers are captured. The user may manually wake the AR reading device using an external user interface.
