Solution Overview

Problem

Conventional electronic devices often require user authorization without ensuring that the user has read or viewed associated textual information, leading to potential data loss, frustration, and resource wastage due to inadvertent actions.

Innovation Solution

Implementing gaze-based control systems that use eye-tracking data to determine if a user has viewed and read textual information before allowing authorization for device actions, such as deleting data or installing software, and dynamically modifying user interfaces based on gaze patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user authorization is required before device actions, then data loss and errors are reduced, but user frustration and operation complexity increase

Engineering Contradiction:
Improveuser authorizationVSAvoiduser operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system monitors user gaze patterns automatically to determine whether the user has read the warning message, eliminating the need for manual acknowledgment. The eye-tracking system self-services the verification process by detecting fixation duration and saccade patterns, allowing authorization to proceed without additional user interaction once reading is confirmed.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual confirmation mechanisms (clicking buttons, pressing keys) with an optical detection system. The eye-tracking technology uses cameras and image processing to detect gaze patterns, substituting the mechanical interaction model with an optical field-based detection system that automatically verifies user attention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If eye-tracking systems are implemented to verify reading, then user errors are reduced, but device complexity increases

Engineering Contradiction:
Improvereading verificationVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The eye-tracking system leverages the existing front-facing camera and processor of the portable device, making the hardware serve multiple functions (photography, video calls, and now eye-tracking for authorization). This universal approach avoids adding dedicated eye-tracking hardware, reducing the complexity increase while maintaining reading verification capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the existing camera infrastructure to capture eye images, creating a visual copy of the user's gaze pattern. This copied visual information is then processed through image analysis algorithms to determine reading status, avoiding the need for specialized sensing hardware while achieving the verification function.

Inventive Principle:
Principle #26Copying

3Reliability

If gaze-based control is used to ensure informed actions, then user errors are reduced, but processing time increases

Engineering Contradiction:
Improveinformed user actionVSAvoidauthorization time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of gaze patterns as the user naturally views the warning message during the normal authorization flow. By monitoring fixation duration and saccade patterns in real-time as the user reads, the system verifies comprehension before the authorization button becomes active, eliminating the need for separate verification steps and reducing overall time loss.

Inventive Principle:
Principle #10Preliminary action

AI summary

Aspects of the subject technology relate to gaze-based control of an electronic device. The gaze-based control can include enabling an option to provide user authorization when it is determined that the user has viewed and/or read text associated with a request for the user authorization. The gaze-based control can also include modifying a user interface or a user interface element based on user views and/or reads. The gaze-based control can be based on determining whether a user has viewed and/or read an electronic document and/or a physical document.
