Gaze-Based Digital Object Navigation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in interacting with digital objects, such as pictures and videos, on devices like digital TVs and wall displays, as they cannot input commands using traditional methods like keyboards or remote controllers, and struggle to navigate through numerous channels for information like EPG, news, weather, and traffic updates.
Innovation Solution
A digital object navigation apparatus that collects gaze and gesture information from users to determine navigation, zoom rates, rendering quality, annotation intensity, and 3D location information, allowing for intuitive interaction and improved immersion without separate input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input methods (keyboard, mouse, remote controller) are used to interact with digital objects on wall displays, then command input capability is maintained, but user interaction becomes difficult and cumbersome
Solution Approach 1:
The patent replaces mechanical input devices (keyboard, mouse, remote controller) with gaze-based interaction. The system uses eye tracking to detect where the user is looking on the display and interprets this gaze information as selection or navigation commands, eliminating the need for physical input hardware while maintaining interaction capability.
Solution Approach 2:
The system enables users to interact with digital objects using their natural gaze behavior without requiring separate input devices. The display itself serves dual purposes: showing content and receiving input commands through gaze detection, making the system self-sufficient and eliminating dependency on external input hardware.
2Productivity
If users navigate through numerous channels using remote controllers, then information access capability is maintained, but operation becomes difficult and time-consuming
Solution Approach 1:
The system continuously monitors user gaze position and uses this feedback to automatically determine which digital object or channel the user intends to access. The gaze tracking provides real-time information about user intent, allowing the system to dynamically navigate to the selected content without requiring manual channel-by-channel browsing through remote controls.
Solution Approach 2:
The system performs preliminary navigation actions based on predicted user intent from gaze patterns. By analyzing where the user is looking and how their gaze moves, the system can proactively select and transition to the intended digital object before the user completes their gaze fixation, reducing navigation time and improving access speed.
3Manufacturing precision
If digital objects are displayed with high quality rendering, then visual quality is improved, but processing load increases
Solution Approach 1:
The patent applies different rendering qualities to different regions of the display based on where the user is gazing. High rendering quality is applied only to the local area where the user's attention is focused, while lower rendering quality is applied to surrounding areas. This selective rendering approach maintains visual quality where it matters most while significantly reducing overall processing load and energy consumption.
Data Source
AI summary
A digital object navigation apparatus and method using gaze information of a user is provided. The digital object navigation apparatus may collect gaze information and gesture information of the user, may determine navigation information with respect to a digital object including a zoom rate, a rendering quality, or an intensity of an annotation, and may navigate in the digital object. The user may navigate in the digital object by only gazing without separate manipulation.
