Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing digital imaging systems face limitations in accurately associating metadata with images, as users may forget important details or be reluctant to provide metadata, and current methods require manual selection and entry, which can be cumbersome and inefficient.

Innovation Solution

Integration of an eye-tracking system in digital imaging devices that tracks the user's gaze and allows for voice or text input of comments, automatically associating them with the viewed scene locations, enabling more intuitive and precise metadata capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If manual cursor navigation and text entry methods are used for metadata input, then metadata can be associated with image elements, but the process becomes cumbersome and time-consuming

Engineering Contradiction:

Improvecompleteness of metadataVSAvoidtime required for metadata entry

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent replaces manual cursor navigation and text entry (mechanical interaction) with eye-tracking technology that detects gaze direction optically. The system automatically associates metadata with image elements based on where the user is looking, eliminating the need for manual positioning and typing while preserving complete metadata association.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs automatic metadata association based on user gaze patterns without requiring active user input for positioning. The eye-tracking system and processor work autonomously to link comments with corresponding scene locations, making the metadata capture process self-service and significantly reducing time investment from the user.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If users are required to carefully select terms and provide detailed metadata, then more precise image description is achieved, but user burden increases

Engineering Contradiction:

Improveprecision of image descriptionVSAvoidease of metadata provision

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the complex mechanical process of careful term selection and text entry with simple gaze-based interaction. Users naturally look at elements they want to describe, and the system automatically captures this intent, maintaining precise image description while dramatically simplifying the operation required from users.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs preliminary action by automatically preparing and associating metadata based on gaze detection before the user needs to provide detailed descriptions. This preliminary gaze-based selection eliminates the burden of careful term selection while preserving precision, as the system has already identified the target elements through eye tracking.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If users provide metadata after image capture, then reflection and additional information can be added, but important details are forgotten

Engineering Contradiction:

Improveretention of scene detailsVSAvoidtime delay between capture and metadata entry

Core Design Contradiction:

Loss of informationVSDuration of action of moving object

Solution Approach 1:

The patent enables preliminary metadata capture by detecting user gaze and collecting comments during the image capture moment itself. This preliminary action ensures that scene details are recorded while fresh in the user's memory, eliminating information loss that would occur with delayed metadata entry.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuity of useful action by allowing metadata collection to occur continuously during the natural viewing and capture process. Users can provide comments naturally as they look at different scene elements, creating an uninterrupted flow that preserves temporal context and prevents forgetting important details.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A method for providing user comments relating to a scene captured by an image capture device and a digital imaging device configured to implement the method are described. In one aspect, a scene to be captured is displayed to a user through a display device of the image capture device. The image capture device uses an eye-tracking system to track where the user is gazing as the user views the scene, and detects and collects a user input that comprises user comments. While the user views the scene, a processor in the image capture device associates the user input with a location in the scene corresponding to an area where the user is gazing.
