EyeSeeCam

EyeSeeCam

The 2008 version of the gaze-driven camera "EyeSeeCam". The eye movement is tracked by cameras attached on both sides using infrared reflecting hot mirrors. The gaze-driven camera follows saccades, smooth pursuit, and stabilization movements, caused by the vestibulo-ocular reflex.

EyeSeeCam is a unique and award-winning camera system that is controlled with the eyes. It is the only system that can record what the eyes of its user really see. Unrestricted user mobility and field of view as well as the utilization of biological image stabilization reflexes are main benefits of EyeSeeCam. Imagine to see through the eyes of:

  • a surgeon who uses EyeSeeCam to film an operation for documentation and teaching purposes
  • a scientist who uses EyeSeeCam to examine human natural visual exploration in the wild

EyeSeeCam combines and enhances two technologies:

  1. An ultra-mobile eye tracker that measures 3D eye position at unprecedented frame rates of up to 600 Hz.
  2. A camera motion control unit with servo motors that steer a head-mounted camera to the target of gaze.

An off-the-shelf notebook records video files with resolutions of up to 752×480 pixels to hard disk. A novel picture-in-picture functionality combines the image of the gaze camera with another image from a wide-angle scene camera. Just as a magnifying lens, this “hybrid perspective” gives the impression of a sharp image at the target of gaze.

EyeSeeCam VOG

EyeSeeCam VOG setup in a lightweight design that is suited for monocular and binocular eye and head movement analysis under mobile or bedside conditions. Inertial sensors are integrated into the cameras.

Video-Oculography (VOG), also known as video-nystagmography (VNG), is commonly used for the examination of eye movement pathologies in patients with vertigo and ocular motor disorders.

EyeSeeCam VOG is unique in that it offers a combination of unprecedented functionalities in a lightweight design:

  • head impulse test
  • 3D examination of horizontal, vertical, and torsional eye movements
  • real-time data analysis with 4 ms latency
  • digital cameras with frame rates of up to 600 Hz
  • spatial resolution of down to 0.01 deg (RMS)
  • battery-powered laptop mobility
  • optional AD/DA interface for external synchronisation
  • recording of head movements by an integrated 6-DOF inertial measurement unit
  • head-centric calibration with integrated laser projector
  • WiFi remote control, e.g., by an iPod / iPhone / iPad

EyeSeeCam VOG now takes a number of objective vestibular tests from the laboratory to the bedside, such as the head impulse test, saccade metrics, and caloric irrigation test.

    The 2009 version of EyeSeeCam VOG is shown. The workflow of a sample caloric irrigation test is demonstrated togehter with other tests of ocular motility such as optokinetics, smooth pursuit, and saccade metrics. Due to dark semi-transparent glasses, subjects can see only bright visual targets (video projection, white LEDs) but no other objects in a lab with ambient illumination.
