Trackhat Sensor V2 / Opentrack + Hamilton filter
0This is head tracking without markers using an IR camera. Not having markers is very convenient, but it can be challenging to achieve stable settings.

The TrackHat sensor V2 uses infrared light and machine learning to accurately track the movement of your head for your favourite games and simulators.

According to the manufacturer's website, they use machine learning to accurately track the head. In reality, it functions as a regular IR camera, and the device driver is set to Microsoft's webcam. Considering it as an IR filter camera, it might be expensive. However, if machine learning is employed to ensure stability, it would be a different story.
Although the Trackhat Opentrack V3, designed specifically for the V2, can be used, I switched to Opentrack for its flexibility in adjusting settings. I recently researched the Hamilton filter but found limited information and couldn't fully grasp it, so I left it as it was. From what I've gathered, the Hamilton filter seems to smoothly follow movements and easily come to a stop when desired.
Hence, I decided to try it out. It effectively reduces common camera shaking seen in webcams and provides smooth movement.
IRカメラによるマーカーなしのヘッドトラッキングです。マーカーがないのはとても便利なのですが安定した設定を出すまでが大変です。

メーカーHPによると機械学習により正確に頭をトラッキングするとのことです。実際には普通のIRカメラとなります。デバイスドライバーもMSのWebカメラとなります。このため、IRフィルタのカメラとして考えると高額なのでは？というのが実際のところです。機械学習をして安定していくのであれば別だったのですが。
メーカーのV2専用のTrackhat Opentrack v3を使ってもよいですが、細かく設定が変更できるOpentrackに乗り換えました。最近、Hamilton filterについて調べていたのですが資料も少なくよくわからなかったのでそのままにしていました。Hamilton filterがよいとの情報をみて、実際に試してみました。
動きがあるときにはスっと動いて、止めたいときには止まりやすい傾向があるfilterのようです。
というわけで実際に試してみました。Webカメラ系でよくある揺れも抑えることができ、動きも滑らかなようです。
