    • An eye movement tracking device that can be mounted to standard eyeglasses as disclosed. The device comprises an illumination source, a time-of-flight (TOF) camera and a processor. The source transmits energy within a frequency band from a location proximate to an eye of a person, such that at least a first portion of the transmitted energy is reflected off a lens of eyewear worn by the person to subsequently reflect off the eye, and such that at least a second portion of the transmitted energy is transmitted through the lens to reflect off objects in the person's environment. The TOF camera detects reflections of at least the first portion of the transmitted energy, and distinguishes them from other energy detected by the TOF camera in said frequency band, based on TOF principles. The processor uses the detected reflections of the first portion of the transmitted energy to determine eye position.
    • 如所公开的,可以安装到标准眼镜上的眼睛运动跟踪装置。 该装置包括照明源,飞行时间(TOF)照相机和处理器。 源从位于人眼附近的位置的频带内传送能量,使得所传送的能量的至少第一部分被人的眼镜的镜片反射,以随后反射出眼睛。 透射能量的至少第二部分透过透镜以反射人的环境中的物体。 TOF摄像机根据TOF原理检测至少第一部分发射能量的反射,并将它们与TOF相机在所述频带中检测到的其他能量进行区分。 处理器使用检测到的透射能量的第一部分的反射来确定眼睛位置。
