论文摘要
我们介绍了一个新的目光跟踪器，用于头部安装显示器（HMD）。我们使用发射二极管（LED）修改两个现成的HMD，以凝视着凝视。我们的关键贡献是利用LED的传感能力来为虚拟现实（VR）应用创建低功率凝视跟踪器。使用最小硬件，使用在移动设备上运行的轻量级监督高斯流程回归（GPR），可以实现一种简单的方法，以实现良好的准确性和低潜伏期。使用我们的硬件，我们表明，基于Minkowski距离测量的GPR实现优于常用的基于径向基于函数的支持向量回归（SVR），而无需精确确定免费参数。我们表明，我们的凝视估计方法不需要复杂的尺寸降低技术，特征提取或由于离轴光学路径而引起的失真校正。我们通过样品吸引人的应用展示了两个完整的HMD原型，并使用我们的原型报告了一系列主观测试。
We introduce a new gaze tracker for Head Mounted Displays (HMDs). We modify two off-the-shelf HMDs to be gaze-aware using Light Emitting Diodes (LEDs). Our key contribution is to exploit the sensing capability of LEDs to create low-power gaze tracker for virtual reality (VR) applications. This yields a simple approach using minimal hardware to achieve good accuracy and low latency using light-weight supervised Gaussian Process Regression (GPR) running on a mobile device. With our hardware, we show that Minkowski distance measure based GPR implementation outperforms the commonly used radial basis function-based support vector regression (SVR) without the need to precisely determine free parameters. We show that our gaze estimation method does not require complex dimension reduction techniques, feature extraction, or distortion corrections due to off-axis optical paths. We demonstrate two complete HMD prototypes with a sample eye-tracked application, and report on a series of subjective tests using our prototypes.
