    Prescription lenses built for Eye_Tracker

    Co-developed with professional opticians

    These are not generic lens inserts. They are shaped around where Eye_Tracker's cameras sit inside the headset.

    The goal is simple: correct your vision while keeping eye tracking reliable and your view clear.

    A better fit for VR users who need prescription support without giving up stable eye tracking.

    Lens compatibility note

    During development, we found that standard VR prescription inserts cannot clear the eye-tracking camera position. Using them would force a compromise in camera placement and viewing angle, reducing recognition accuracy and tracking range.

    Eye_Tracker prescription lenses use a customized edge shape matched to the camera view and imaging needs, so the camera can stay in a better position while the lenses remain comfortable.

    Existing VR prescription inserts and third-party lenses are physically incompatible with Eye_Tracker and cannot be installed. This is a structure and lens-shape issue, not software. If you need vision correction, use Eye_Tracker lenses from this store or contact lenses. Standard framed glasses are also not recommended.

    Use the headset's own Wi-Fi path

    Paper_Tracker sends tracking data through the headset's Wi-Fi connection instead of being locked to a separate 2.4 GHz receiver. It follows what your headset and router support: Wi-Fi 6 on headsets such as PICO 4, Wi-Fi 6E on Quest 3 / Quest 3S, and Wi-Fi 7 on PICO 4 Ultra where available.

    That lets tracking data use the cleaner high-bandwidth Wi-Fi path already used by modern standalone VR, helping avoid the crowded 2.4 GHz ecosystem shared by many body trackers and peripherals. Actual latency and stability still depend on headset model, router, band, distance, PC/network load, and local interference.

    The Paper_Tracker App is available from the Meta Store and Pico Store.

    Dual cameras for detailed eye movement data

    Two eye-facing cameras with controlled IR illumination capture gaze origin and direction, pupil size, pupil position, and eye openness.

    The IR illumination system has been evaluated by an independent laboratory under GB/T 20145-2006, aligned with IEC 62471:2006 / CIE S 009/E:2002, and classified as RG0, Exempt Group.

    Unlike many DIY eye-tracking builds, Paper_Tracker uses a tested illumination design intended for long sessions near the eyes.

    Model tuned for expressive VRChat tracking

    Uses GPU acceleration to process face and eye tracking data

    Outputs avatar expression data in real time

    Typical CPU usage ≤3% under supported configurations

    Tuned for smoother, more natural expression changes.

    We keep improving the model and usually ship updates on a weekly cadence.

    Lightweight hardware with a cleaner finish

    Injection-molded parts are paired with industrial MJF components to keep the kit light, durable, and precise where alignment matters.

    Shaped from scans of real headset shells

    Structured-light and laser scans help the mounts follow the headset contour closely, with tool-free installation and stable alignment.

    Power your headset without messy wiring

    PowerHub

    The custom PowerHub supports up to 27W USB-C PD fast charging, helping keep the headset powered while keeping the tracking setup compact and tidy.

    If you use a battery head strap such as the BOBOVR S3 Pro Super Strap, the extension cable is recommended for cleaner routing and better fit.

    Buy extension cable

    More comfortable when resting on your side

    Custom right-angle USB-C cable

    The right-angle cable reduces the bulge on the side of the headset, so it is less likely to press into your face when you lie down during VR rest or sleep sessions.

    Handle cables and connectors carefully. Avoid excessive pressure, sharp bending, or pulling.

    Add SteamVR trackers when your setup needs them

    With the optional magnetic quick-release mounting base, it supports HTC Vive Tracker, Tundra Tracker, and other SteamVR-compatible trackers.

    The magnetic quick-release base is an optional accessory and is sold separately.

    Notes & disclaimers

    The eye-tracking module uses 940 nm near-infrared LEDs, a non-laser light source. A professional laboratory evaluated the infrared illumination system under GB/T 20145-2006, aligned with IEC 62471:2006 / CIE S 009:2002, and classified it as RG0 (Exempt Group). In normal use, the infrared light is usually invisible or only faintly visible.

    Wireless connectivity depends on your headset, router and locally permitted bands. Stay close to your router or access point and use 5 GHz or 6 GHz where supported. Tracking and latency also depend on your PC, network load, interference, lighting and software version.

    Charging while playing requires a headset, charger and cable that all support USB-C PD. Power delivery is up to 27W; the actual power depends on these devices and their PD negotiation.

    Framed glasses may affect eye tracking. If you need vision correction, consider contact lenses or prescription lenses designed for Paper_Tracker Eye_Tracker.

    Appearance, accessories and compatibility can vary by headset model and Kit configuration. Please check the details for your selected configuration. Product images are illustrative.

    Tracking models, compatibility and software features will continue to be updated. The content and timing of updates depend on the actual release.

    Third-party accessories, modified parts or unsupported setups may affect fit, charging or tracking. Model performance figures on this page use an October 9, 2025 dataset snapshot, tested on an AMD Radeon RX 6800 + Ryzen 5 7500F. Results may differ with other system configurations and software versions.

    Using an HTC Vive Tracker, Tundra Tracker or other SteamVR tracker requires the optional magnetic quick-release mount. Both the tracker and mount are sold separately.

    Fantastic kit! Software is well developed, super easy to set up and get going right off the bat. Even though my unit was one of the earlier units, it did not feel like a early prototype.

    Getting up and going was fairly painless and connection to PC is seamless without any hiccups. Just works. Can tell developer(s) really put a lot of work into this project.

    とりあえず2回使用しました。別の製作者様によるFTアドオンを2種類使い、サンプルアバターを含む複数のアバターでテストしております。デフォルトの未調整の状態では、どちらのアドオンでも目が動きすぎてしまい、ほぼ白目のように上を向いてしまう現象が起きました。ヘルプを確認したところ中国語のみで日本語ページに遷移できなかったため、翻訳を頼りにフェイスクッションの高さを3段階のうち最も高い（目から離れる）設定に変更したところ、症状が改善されました。目の可動域などを調整する機能は見当たらないため、こちらはアバター側で調整を試みる予定です。また、中心を注視するものや光を追うものなど、キャリブレーションを何度も試みましたが効果に変化はありませんでした。口元に関しては、カメラの範囲の影響かすぐに口をへの字に結んだような表情になってしまい、調整を重ねてもその部分だけは少し微妙な印象です。眉毛は反応しなかったため、よく分からず現在はオフにしています。目の見開き機能については現時点で全く機能しておらず、キャリブレーション自体が上手くいかないためこちらもオフに設定しました。これほど調整が必要であれば、フェイスクッションなどは最初から別売りで販売してほしいと感じます（もし公式の日本語説明書が既にあったのであれば、見つけられず申し訳ありません）。今週末にアバター側での微調整を行う予定ですが、この価格でこれだけの機能が得られるのであれば、正直コストパフォーマンスは非常に高いと感じております。現時点で購入したことを後悔はしていません。素晴らしい商品をありがとうございました。

    詳しいフィードバックをありがとうございます。
    まず説明書についてですが、以下のページをご確認ください。
    https://docs.papertracker.top/
    ページ右上の言語切り替えから日本語を選択していただくと、完全な日本語版の説明書をご覧いただけます。日本語の説明ページが分かりにくく、すぐに見つけられなかった点については申し訳ありません。
    目の動きが大きすぎて、ほぼ白目のように上を向いてしまう症状については、こちらでは基本的に Avatar 側の設定が原因である可能性が高いと判断しています。特に、Avatar 側の中心点オフセット補正パラメータが未調整であることが影響している可能性もあります。この症状は、単純にアイトラッキング側のキャリブレーションだけで解決するものではなく、Avatar 側の目の可動範囲、視線の中心点、オフセット設定などを合わせて調整する必要がある場合があります。
    口元についても、カメラの角度や認識範囲の調整方法がまだ正しく伝わっておらず、撮影されている画像の角度が適切でないことが原因で、口元の認識に影響が出ている可能性があります。
    可能でしたら、私たちの Discord の support チャンネルからチケットを作成していただけますでしょうか。実際の装着状態、カメラ映像、Avatar 側の設定を確認しながら、より具体的な調整方法をご案内いたします。

    Thank you very much for your detailed feedback.
    First, regarding the documentation, please check the following page:
    https://docs.papertracker.top/
    You can switch the language from the top-right corner of the page. After switching to Japanese, you should be able to view the full Japanese manual. We apologize that the Japanese documentation was not easy to find.
    Regarding the issue where the eyes move too much and almost look like they are rolling upward, we believe this is most likely caused by the Avatar-side settings. It may also be related to the fact that the Avatar’s eye center offset calibration parameters have not been adjusted at all. This kind of issue usually cannot be solved only through eye-tracking calibration. In many cases, the Avatar-side eye movement range, gaze center point, offset settings, and related parameters also need to be adjusted.
    As for the mouth tracking, it may be because the camera angle and recognition range have not been adjusted correctly, causing the captured image angle to be incorrect and affecting the mouth recognition result.
    If possible, please create a ticket in the support channel on our Discord server. We can then check your actual wearing position, camera image, and Avatar settings, and provide more specific guidance for adjustment.
