Publication number: 20240064277Abstract: A method for controlling the video display of a virtual 3D object or scene on a 2D display device is provided. A virtual video camera, controlled by a virtual-video-camera state variable consisting of camera control and location parameters, generates the 2D video of the object or scene. A target virtual camera state, representing an optimal view of a given surface point, is generated for each model surface point. A 2D coordinate of the image display is received from a user, either by looking at a point or selecting it with a mouse click. A corresponding 3D designated object point on the surface of the object is calculated from the received 2D display coordinate. The virtual camera is controlled to move its view toward the 3D designated object point with dynamics that allow the user to easily follow the motion of the designated object point as he watches the video.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Inventors: Dixon Cleveland, Preethi Vaidyanathan

Patent number: 10894577Abstract: 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.Type: GrantFiled: March 26, 2019Date of Patent: January 19, 2021Inventors: Jason Smith, Morten Opprud Jakobsen, Greg Andrew Vanderbeek, Simon Elnicki Hafner, Hanxiong Yang, Alexander Jacobson Rosenberry, Steven Andrew Simkins, Chase Dixon Cleveland, Eric Stefan Perkey

Publication number: 20190384387Abstract: 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.Type: ApplicationFiled: June 7, 2019Publication date: December 19, 2019Inventors: Dixon Cleveland, Peter L. Norloff, Matthew Norloff

Publication number: 20180160035Abstract: 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.Type: ApplicationFiled: February 5, 2018Publication date: June 7, 2018Inventor: Dixon Cleveland

Patent number: 9986138Abstract: 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.Type: GrantFiled: April 21, 2017Date of Patent: May 29, 2018Assignee: LC Technologies, Inc.Inventors: Dixon Cleveland, Jonathan Alexandar West

Patent number: 9760772Abstract: 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.Type: GrantFiled: March 20, 2015Date of Patent: September 12, 2017Assignee: LC Technologies, Inc.Inventors: William Maher, Dixon Cleveland

Patent number: 9642523Abstract: 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.Type: GrantFiled: December 20, 2016Date of Patent: May 9, 2017Assignee: LC Technologies, Inc.Inventor: Dixon Cleveland

Publication number: 20170099433Abstract: 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.Type: ApplicationFiled: December 19, 2016Publication date: April 6, 2017Inventor: Dixon Cleveland

Patent number: 9386921Abstract: 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.Type: GrantFiled: February 28, 2015Date of Patent: July 12, 2016Assignee: LC Technologies, Inc.Inventor: Dixon Cleveland
