  • Publication number: 20190384387
    Abstract: In video eyetracking, precise measurement of the camera-to-eye distance is critical to the accurate calculation of the user's gazepoint and/or gaze line in space. In various embodiments, a narrow-beam time-of-flight (TOF) range finder device is used to measure the camera-to-eye distance in a video eyetracker. The narrow beam of light, electronically directed toward the eye, provides a consistent measurement to the eye itself, despite varying head positions and orientations as the user moves around freely within the eyetracker camera's field of view. The direction controls that keep the narrow light beam pointed at the eye are obtained from the eyetracker's eye-detection functions that process the eye images captured by the eyetracker's video camera.

  • Publication number: 20190300116
    Abstract: A bicycle drive system includes a front face gear, a rear face gear, a drive shaft, and a front roller-toothed gear assembly coupled to the first end of the drive shaft, and a rear roller-toothed gear assembly coupled to the second end of the drive shaft. Both the front roller-toothed gear assembly and the rear roller-toothed gear assembly include one or more roller elements. The roller-toothed gear assemblies are advantageous in ensuring the bicycle drive system is highly efficient, and is only minimally or not at all affected by dirt, water, contaminants, or other foreign matter typically experienced in un-clean riding conditions.

  • Publication number: 20180160035
    Abstract: A robot system controls a robot in a tele-operation. The system includes a robot and a remote gaze-controlled camera (GCC) system. The robot includes one or more manipulators and a vision system that provides a remote operator a close up view of a work area of the robot from the robot's perspective. The robot and the one or more manipulators are remotely controlled by the hands of the operator. The GCC system remotely controls the vision system of the robot. The GCC system relieves the operator of additional manual control of the video camera and the cognitive workload of manual control of the video camera. The GCC system includes a video display for remotely displaying video from the vision system to the operator, an eyetracker for determining an eye/head activity variable of the operator's eye, and a processor that remotely controls the video camera based on the eye/head activity variable.

  • Patent number: 9986138
    Abstract: A device for performing eyetracking on a handheld device includes and eyetracking camera and an eyetracking camera boom mount. The eyetracking camera boom mount physically and electrically connects a handheld device and the eyetracking camera. The eyetracking camera boom mount includes an extension boom that positions the eyetracking camera behind the user's hands. The extension boom provides the eyetracking camera with a view of the user's eyes that is unobstructed by the user's hands. The device can further include an operating scene camera for monitoring a person's hand operations on the handheld device. The operating scene camera can be mounted on the same extension boom as the eyetracking camera or on a separate extension boom.

  • Patent number: 9760772
    Abstract: A system and method are disclosed for using a camera image of a user's eye as a visual stimulus for the calibration point in an eyetracking calibration system. A camera image of a user's eye is generated on a user display using an eyetracker. The camera image of the user's eye is used as a visual stimulus of a calibration point. In an embodiment, the center of the pupil of the camera image of the user's eye represents the coordinates of the calibration point on the user display. In another embodiment, the center of the corneal reflection of the camera image of the user's eye represents the coordinates of the calibration point on the user display.

  • Patent number: 9642523
    Abstract: An asymmetric aperture device for a camera is provided that improves light gathering properties by increasing both the light gathering opening of the aperture and the number of light producing light sources placed on the aperture. An asymmetric aperture design is provided that utilizes a significantly larger portion of the camera lens. The tradeoff between the competing objectives of maximizing camera depth of field and maximizing the production of useful focus-condition information within the camera image is optimized. More illumination is provided without significantly increasing the lateral size of the illuminator pattern.

  • Publication number: 20170099433
    Abstract: A setting of a video camera is remotely controlled. Video from a video camera is displayed to a user using a video display. At least one eye of the user is imaged as the user is observing the video display, a change in an image of at least one eye of the user is measured over time, and an eye/head activity variable is calculated from the measured change in the image using an eyetracker. The eye/head activity variable is translated into a camera control setting, and an actuator connected to the video camera is instructed to apply the camera control setting to the video camera using a processor.

  • Patent number: 9386921
    Abstract: A miniature eye tracking system is disclosed that includes a camera, a microelectromechanical (MEMS) device, and a processor. The camera images an eye. The MEMS device controls the view-direction of the camera. The processor receives an image of the eye from the camera, determines the location of the eye within the camera image, and controls the MEMS to keep the camera pointed at the eye. In another embodiment, the MEMS device controls an adjustable focus of the camera. The processor determines the focus condition of the eye image, and controls the MEMS device to maintain a desired focus condition of the camera on the eye. In another embodiment, the MEMS device controls an adjustable camera zoom. The processor determines the size of the eye image within the overall camera image, and controls the MEMS to maintain a desired size of the eye image within the overall camera image.

  • Patent number: 9244528
    Abstract: Effective patient-centered care in a hospital relies heavily on the ability of patients to communicate their physical needs to care givers. If a patient is unable to speak, he has limited means of communicating at a time when he needs it the most. The embodiments presented here, generally referred to as EyeVoice, include unobtrusive eye-operated communication systems for locked-in hospital patients who cannot speak or gesture. EyeVoice provides an alternate means of communication, allowing hospital patients to communicate with their care givers using their eyes in place of their voices. Simply by looking at images and cells displayed on a computer screen placed in front of them, patients are able to: answer questions posed by caregivers; specify locations, types and degrees of pain and discomfort; request specific forms of assistance; ask or answer care related questions, and help direct his own care.
