Testing Nvidia Broadcast's Eye Contact Effect

Nvidia Broadcast's eye contact effect has generated quite a bit of buzz online, and I wanted to put it to the test. In this article, we will explore the capabilities and limitations of this new feature, version 1.4.0.29. I have set up a video layout that includes the original footage, footage from Nvidia Broadcast, and a screen capture. Let's dive into the different scenarios I tested and how well the eye contact effect held up.

Tiling the Videos

In the upper left corner of the video layout, we have the original footage captured with OBS. Using a green screen, I created the illusion of being in a movie theater. On the upper right HAND, we have the footage generated by Nvidia Broadcast. It successfully replaced the background seats but retained the fake seat I am sitting in. In the bottom, we have a screen capture to observe how well the eye contact effect retains focus.

Dragging the Window

To test how well Nvidia Broadcast retains eye contact when the window is moved, I dragged the window around while monitoring my eyes. Initially, the eye contact effect successfully locked onto the camera, even when my gaze shifted towards the window. However, when I moved the window to the furthest corners of my monitor, I observed a blind spot where the eye contact effect struggled. This blind spot seemed to occur at around the three-quarter mark of my monitor.

Widen and Close Eyes

I wanted to see how well the eye contact effect adjusted to eye movements. When I widened my eyes, Nvidia Broadcast did a pretty good job of tracking them. However, when I tried to close one eye or both eyes, the eye contact effect was less effective. It had difficulty maintaining the illusion of eye contact in these scenarios.

Speaking to the Webcam

Keeping your head forward while speaking to the camera can enhance the naturalness of the eye contact effect. When I looked to the side while speaking, Nvidia Broadcast managed to keep my eyes centered. This technique proved useful in creating a more engaging and realistic eye contact effect.

Occlusions and Rubbing Eyes

I tested how well Nvidia Broadcast handled occlusions, such as rubbing my eyes. Surprisingly, the eye contact effect held up relatively well in these situations. Even when I covered one eye or both eyes with my hands, the eye contact effect continued to track and adjust accordingly.

Shifting and Rotating Eyes

To assess the eye contact effect's ability to handle eye movements, I shifted and rotated my eyes in different directions. The tracker successfully kept my eyes centered when I moved them up, down, left, and right. I also performed clockwise rotations and wide rotations, and the eye contact effect consistently maintained focus.

Squinting and Rapid Blinking

Squinting proved to be an effective way to manipulate the eye contact effect. When I squinted, the eye contact effect adjusted accordingly and continued to maintain eye contact. Rapid blinking, however, appeared to challenge the eye contact effect, causing it to intermittently lose focus and attempt to reestablish eye contact.

Eyebrow Movements

I experimented with various eyebrow movements to see how well Nvidia Broadcast responded. Although eyebrow movements do not directly affect eye contact, they are an essential component of face-to-face interactions. The eye contact effect remained stable during eyebrow movements, further enhancing the overall realism.

Close-ups and Eye Color Changes

I performed close-ups by moving closer to the camera while maintaining eye contact. In these scenarios, Nvidia Broadcast still managed to track my eyes and maintain the illusion of eye contact. However, I noticed that when I looked slightly off-center, it appeared to alter the color of my eyes, which may be a consideration for individuals using this feature.

Pros:

• Nvidia Broadcast's eye contact effect successfully creates the illusion of eye contact with the camera.
• It adapts well to head movements, occlusions, and eye shifts.
• The eye contact effect remains stable during eyebrow movements and close-ups.
• Squinting proves to be an effective way to control the eye contact effect.

Cons:

• The eye contact effect struggles with extreme eye movements, such as rapid blinking.
• Closing one eye or both eyes challenges the eye contact effect's ability to maintain focus.
• Looking too far to the sides or corners of the monitor may result in a blind spot for the eye contact effect.

Based on my testing, the eye contact effect in Nvidia Broadcast has the potential to enhance presentations and webinars, creating a more engaging and interactive experience for viewers. It is important to keep in mind the limitations and adjust your positioning and movements accordingly to maximize the effectiveness of the eye contact effect.

In conclusion, Nvidia Broadcast's eye contact effect is a promising feature that can revolutionize the way we engage with our audience virtually. While it may have some limitations under certain circumstances, it has the potential to enhance the authenticity and impact of online presentations and webinars. Give it a try and let me know what you think!

Highlights:

• Nvidia Broadcast's eye contact effect retains focus on the camera, even when the window is moved.
• The eye contact effect struggles with extreme eye movements and closing one or both eyes.
• Squinting and head-forward positioning enhance the naturalness of the eye contact effect.
• Occlusions, such as rubbing the eyes, do not significantly affect the eye contact effect.
• Eyebrow movements and close-ups are effectively tracked by the eye contact effect.

FAQ:

Q: Can Nvidia Broadcast's eye contact effect maintain focus while I move around? A: Yes, as long as your head remains within a reasonable range and you don't move too far to the sides or corners of the monitor.

Q: How does the eye contact effect handle extreme eye movements like rapid blinking? A: Rapid blinking may cause intermittent loss of focus as the eye contact effect attempts to regain eye contact.

Q: What happens if I close one eye or both eyes while using the eye contact effect? A: Closing one or both eyes challenges the eye contact effect's ability to maintain focus and eye contact.

Q: Can I use the eye contact effect with a green screen setup? A: Yes, the eye contact effect works effectively with a green screen setup.

Q: How does the eye contact effect handle occlusions, such as rubbing my eyes? A: The eye contact effect adjusts well to occlusions and continues to maintain eye contact even when momentarily covered.
