Solution Overview

Problem

AR glasses used for enhanced reading have limited battery life and require frequent activation, consuming significant power and being burdensome for users.

Innovation Solution

Implement a reading mode that puts AR glasses into a sleep state intermittently to conserve battery life, downloads code modules when signal is strong, and uses low-energy communication protocols to extend battery life and reduce power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If AR glasses are activated frequently to provide virtual media content, then user interaction capability is improved, but battery life deteriorates

Engineering Contradiction:

Improveuser interaction capabilityVSAvoidbattery life

Core Design Contradiction:

Adaptability or versatilityVSDuration of action of moving object

Solution Approach 1:

The system implements periodic scanning of reading materials at predetermined intervals rather than continuous operation. The processor scans for codes embedded in reading materials periodically, allowing the device to enter low-power states between scans while still maintaining the ability to detect and respond to virtual media content when available

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system pre-loads virtual media content and code modules into memory before they are needed. By determining availability of virtual media content in advance and pre-loading it, the system reduces the need for frequent activations and intensive processing during actual reading sessions, thereby extending battery life

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If code modules are downloaded frequently to provide enhanced reading features, then functionality is improved, but energy consumption increases

Engineering Contradiction:

ImprovefunctionalityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system determines availability of code modules in advance and downloads them to memory before they are needed for reading. This preliminary action allows the device to operate in a low-power state during reading sessions while having all necessary code modules already available locally, eliminating the need for energy-intensive real-time downloads

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Once code modules are downloaded to memory, they remain available for continuous use throughout reading sessions. The system maintains these code modules in memory across multiple reading sessions, eliminating repeated downloads and associated energy consumption while preserving full functionality

Inventive Principle:

Principle #20Continuity of useful action

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.
