Saccadic Eye Motion Viewer Interest Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eye movement tracking technologies are limited in objectively measuring viewer interest in visual stimuli, such as commercials, as they primarily rely on subjective telephone surveys and cannot distinguish between levels of engagement like boredom or high stimulation, and do not provide real-time, accurate data for advertisers to optimize content effectively.
Innovation Solution
Monitoring and displaying saccadic eye motion as an indicator of viewer interest by using available eye movement tracking apparatus to measure and synchronize saccadic eye movements with visual stimuli, allowing for real-time objective analysis of viewer engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If telephone surveys are used to determine viewer interest, then subjective feedback can be collected, but the accuracy and reliability of the measurements deteriorate due to subjectivity and memory limitations
Solution Approach 1:
The patent replaces the mechanical/survey-based system of collecting subjective viewer feedback with an optical/electronic eye tracking system that objectively measures saccadic eye movements. This substitution eliminates human subjectivity and memory limitations, providing reliable real-time data on viewer engagement levels through physiological responses rather than self-reported information.
2Loss of information
If traditional eye movement tracking is used to determine where viewers look, then spatial attention data can be obtained, but the ability to measure the level of viewer interest (boredom, stimulation, engagement) deteriorates
Solution Approach 1:
The patent changes the measurement parameter from spatial location (where the eye looks) to temporal frequency characteristics (how the eye moves). By analyzing saccadic movement patterns, velocities, and inter-saccadic intervals, the system derives engagement level information that traditional spatial tracking cannot provide, thereby recovering the lost information about viewer interest intensity.
Solution Approach 2:
The patent introduces saccadic eye movement patterns as an intermediary between visual stimulus and viewer interest measurement. Rather than directly measuring interest (which is internal and unobservable), the system uses saccadic characteristics as a measurable intermediary that correlates with engagement levels, enabling indirect but objective assessment of viewer interest.
3Loss of time
If eye movement tracking apparatus is used to monitor viewer attention, then real-time data collection is enabled, but the ability to distinguish between different levels of viewer interest (boredom, engagement, stimulation) deteriorates
Solution Approach 1:
The patent segments the continuous eye movement signal into discrete saccadic events, each characterized by specific parameters (amplitude, velocity, duration, inter-saccadic interval). This segmentation allows the system to analyze individual saccadic patterns and differentiate between various engagement states, thereby recovering the information about interest level differentiation that would be lost in continuous analysis.

AI summary
Technique for providing an indication of viewer interest in response to visual stimuli. A viewer is exposed to visual stimuli. The viewer's saccadic eye motion occurring while the viewer is being exposed to the visual stimuli are measured. The visual stimuli are displayed together with the measured saccadic eye motion that occurred while the viewer was being exposed to the visual stimuli as an indication of the viewer's interest in such visual stimuli.
