👁️ Seeing Is Not Enough, You Have To See Correctly: Angular Vision and Eye Tracking in Conference Halls
No matter how strong the technology investment is in conference, seminar or training halls, if the audience cannot easily see the content on the stage from any point of the hall, that investment is inefficient. Visual accessibility is directly related not only to the "visibility of the screen" but also to biomechanical details such as the viewer's eye level, head position, viewing angle and focus time. It carries Is it important?
Angular view refers to the angle from which the audience watches the screen or projection screen on the stage. The human eye naturally tends to look forward. If the viewing angle deviates excessively up, down or to the side, this creates stress on both the eye muscles and the neck muscles. by:
Vertical viewing angle: +15° above eye level / -30° down
Horizontal viewing angle: ±30° from image center right/left
Angles outside these limits mean discomfort, distraction and fatigue for the viewer. Therefore, in the hall design, each seat must be positioned according to these boundaries. and Focus Constancy
The concept of "eye tracking", which is frequently used in modern ergonomics, examines the movement of the viewer's gaze on the screen and the focusing time. Particularly for viewers looking from upright or oblique angles: What it does
maintains its focus It was determined that he experienced fatigue as the viewing time increased. Taking these data into consideration, Nish Global makes seating planning based not only on visuality but also on visual comfort. Because a well-designed hall appeals not only to the eye but also to human physiology.

🧮 How is the viewing distance? How is it calculated?
Another critical element is the viewing distance between the seat and the screen. This distance is calculated based on the height of the screen with the following formula:
📏 Minimum Distance = Screen height x 2
📏 Maximum Distance = Screen height x 6
So if a 2 meter high projection screen is used, the farthest seat should not exceed 12 meters. Otherwise, the viewer may miss the details or have to squint constantly. Inclination
In halls with flat floors, the audience often has problems seeing the curtain from behind due to the head of the person in front of them or the lower level of the curtain. For this reason:
12–15% slope in halls with 12–15 rows and above recommended
In non-sloping halls, the curtain should be at least 90–100 cm above the floor. seat(s) should start (should be blocked) Planning
Nish Global prioritizes engineering based on human physiology, not just screen size or device resolution, in halls where projection is used. In each project:
📍 Eye level in the living room scan
🔍 Seat based angular view analysis
🧪 Eye tracking simulations
🛑 Halls that offer not only traceable but also sustainable comfort by controlling light reflection and curtain positioning produces.

🧭 Conclusion
Projection is not just a matter of the screen; If not planned correctly, it can be a critical event that affects the entire salon experience. is the component. Every seat in your hall should be able to see the stage from the most natural perspective, and the audience should not experience physical strain while looking at the stage.
Remember: Everyone has the right to see, but seeing correctly is engineering. wants.
