Analysis & Post-Processing

Gaze data is time-series data comprising scene camera video and gaze position information.

Analysis contents

Supports full or segment-based gaze analysis (standard feature)

Gaze Mapping Function: ViewTracker F (Optional)/ViewTracker G (Standard)

Maps fixation points onto a single reference image, compensating for head movement. Unlike standard analysis (camera coordinates), fixations are displayed in absolute image coordinates for clearer interpretation.

Movizer

Workflow Analysis Software made by DITECT (optional)

Data can be imported into Movizer to compare gaze behaviour between experts and beginners, and to create video-based manuals for visual inspection tasks.

Also compatible with third-party analysis software.

Use cases

Skill Transfer, Visualisation, and Video Sharing for Manufacturing

Gaze Data Visualisation of Skilled Workers
Sharing of Reference Work Procedures
Expert-Novice Comparison, Beginner Training, and Skill Evaluation
Standard Procedure Video Manual

In many manufacturing processes, quality heavily relies on individual human skill. Passing the expertise of seasoned veterans down to less experienced novices is a critical challenge for continuous quality improvement.

Visual and appearance inspections, where "how to use one's eyes" is paramount, have traditionally been difficult to train due to the challenges of verbalizing intuitive know-how. With limited options for quality enhancement, our Eye-Tracking System offers a breakthrough solution. By generating "Gaze Videos" with overlaid visual pointers, this system transforms intuitive looking habits into clear, clear-cut shared assets.

The order in which they look

Sharing objective gaze data provides a clear visual roadmap for beginner training. By comparing their own gaze paths with those of seasoned experts, trainees can easily recognize hidden areas for improvement.

Furthermore, by establishing the correlation between peripheral vision and specific gaze patterns, this approach can evolve from a hypothesis into a proven standard-opening new possibilities for technical skill grading and assessment. Our technology already has a proven track record across manufacturing, plant maintenance, facility management, and vehicle inspection.

Enhancing Driving Safety Training for Bus & Transport Operations

Utilizing driver gaze for training and instruction
Enhancing driver self-awareness during post-drive reviews
Sharing model driving gaze videos for training
Supports both training system integration and standalone operation

In the transit and transportation industry, achieving zero accidents is one of the highest priorities. While companies make continuous efforts daily, a key pillar of this commitment is the training and education used to improve and maintain driver skill standards. Instructors provide a wide range of guidance on driver skills, and "gaze tracking" has becomes one of the most critical elements in this process.

Visualizing driving gaze patterns with View Tracker allows instructors and trainees to share objective facts. Feedback indicates that this approach makes training significantly more effective.

An increasing number of bus companies are replacing their current equipment with our system, as it successfully eliminates common frustrations found in competitor products. Key advantages include quick and automatic calibration, no requirement for dedicated cap, reliable tracking under any weather conditions, and unobstructed field of view, and highly clear digital video output.

The following sections highlight specific examples of how these features are utilized.
