Exploring the Innovative Quest 3 Eye Tracking Addon by a Japanese Engineer

The Exciting Development in Quest 3 Eye Tracking

A Japanese engineer known as “Nami” is generating buzz with plans to create a revolutionary Quest 3 eye tracking addon tailored for the Meta Quest 3 headset. This project has ignited both excitement and skepticism among VR enthusiasts, highlighting the transformative potential of eye tracking technology in virtual reality.

Unveiling Vlugin and the EF Tracker Project

Nami, who brings expertise in computer vision and currently works in the automotive sector in Japan, established a group called Vlugin. He has teamed up with a well-known VRChat user, bbbbb_himiko, to enhance the visibility of the device on social media platforms.

The future product, termed the EF Tracker, aims to elevate the Meta Quest 3 experience by integrating cutting-edge eye tracking and face tracking features through a combination of three cameras and several infrared LEDs. However, this ambitious project has raised significant concerns that deserve careful consideration.

The Formation Journey of Vlugin

Founded in 2023, Vlugin initially sought to collaborate with diVRse, a Japanese startup recognized for its innovation with a product called VRsatile—a prescription lens insert compatible with various headsets. The original vision included developing a variant named VRsatile Eye C, which would feature integrated eye tracking capabilities. However, it was recently announced that this partnership has been terminated due to conflicting expectations.

DiVRse Inc. acknowledged differing visions from both parties, leading to the decision to dissolve the collaboration.

With Vlugin being composed of just one engineer, questions arise regarding the feasibility of this project. Presently, the team is displaying concept renders instead of a fully functional prototype.

Concerns Surrounding the EF Tracker’s Development

There are also accusations that Vlugin has utilized open-source eye tracking software without appropriate licensing or acknowledgment. On their website, they claim to “develop hardware and software,” yet recent actions have sparked inquiries.

The lead developer of EyeTrackVR, a reputable open-source project, discovered similar tracking visualizations in the EF Tracker’s only demonstration video, suggesting possible copying from EyeTrackVR. Following social media scrutiny, Vlugin reportedly deleted the controversial post, escalating suspicions further.

In addition to concerns about their eye tracking software, it is believed that Vlugin has also incorporated elements from the open-source face tracking initiative Project Babble. This project recently amended its GitHub page, clearly stating that commercial use without a license is not allowed.

Safety Protocols and Hardware Concerns

When examining the EF Tracker’s hardware, the implications grow more alarming. Experts have observed that the camera sensors employed by Vlugin appear unusually large compared to standard industry practices for Quest 3 eye tracking. Prohurtz, the EyeTrackVR lead developer, commented that these sensors resemble off-the-shelf components intended for DIY projects, rather than optimized eye tracking solutions.

The infrared emitters used for illuminating the eyes reportedly exceed safety standards. This situation could lead to discomfort, eye strain, and long-term risks like cataracts. Prohurtz’s experience with similar hardware has pointed to adverse effects, including immediate dryness and discomfort. The EyeTrackVR community continues to explore safety protocols regarding infrared emitters, emphasizing the significance of eye health.

Competition in the Quest 3 Eye Tracking Market

Vlugin is not the sole entity developing an eye tracking solution for the Meta Quest 3. A competing startup, Inseye, recently launched a $160 eye tracking addon named Lumi. This device promotes the use of economical photosensors instead of cameras, promising lower computational needs, reduced energy consumption, and overall cost-efficiency. However, information regarding Inseye’s advancements has been sparse since September.

It’s also worth noting that an official eye tracking addon from Meta appears unlikely, as the company’s CTO recently dismissed the concept as unrealistic. Additionally, Meta’s predictions related to face tracking suggest low feasibility.

Nonetheless, HTC has successfully rolled out eye tracking and face tracking addons for its Vive Focus 3, which implies that meaningful advancements could be realized if Meta chose to pursue this direction seriously.

The Road Ahead for the EF Tracker

Currently, Vlugin has not initiated preorders for the EF Tracker and has yet to reveal pricing or a launch date. Given the numerous concerns surrounding the project’s integrity and feasibility, it is wise to exercise caution when contemplating any future investment in this addon.

Vlugin’s Official Response to Criticisms

On January 16, Vlugin responded formally to the concerns raised. They admitted to utilizing components from EyeTrackVR and Project Babble, and pledged to rectify this by providing appropriate credits and licenses upon the software’s official release. They clarified that their team operates on a voluntary basis, aiming to advance face tracking technologies.

Once the EF Tracker is completed, Vlugin plans to share the manufacturing details openly, aligning with the DIY ethos cherished within tech communities. They have also acknowledged safety concerns and are committed to implementing improvements in response to ongoing developments.

The future of the EF Tracker remains uncertain, but the discussions it sparks underscore a growing interest and the hurdles faced in advancing eye and face tracking technologies for immersive virtual reality experiences. Enthusiasts and professionals alike are likely to closely monitor the evolution of this technology. 🌟
