In order for the user to be authenticated, an image is captured of the user while the user is within an interaction zone, which is an area that is within both a field of view of the camera and a suitable distance range from the camera. If the user is not within the suitable distance range from the camera, then feedback is provided indicating that the user is not within the suitable distance range from the camera. Various feedback can be provided, such as one or a combination of audio, visual, and haptic feedback. The feedback notifies the user that an adjustment is to be made to the location of the user and/or the camera in order for the user to be within the interaction zone.

  • Patent number: 9405364
    Abstract: A method of filtering glints by processing an image of a user's cornea to obtain coordinates of desired glints from a configuration of light sources, comprising processing an image, in a first image space, of a user's cornea to determine coordinates of respective multiple positions of glints; and iteratively: selecting from the coordinates a first and a second set of coordinates; computing from the first set of coordinates a transformation that transforms the first set of coordinates into first coordinates of a predetermined spatial configuration; and testing whether the transformation transforms also the second set into positions that match second positions of the predetermined configuration. The coordinates of the desired glints are selected as those first and second sets which are transformed into coordinates that match the first and second coordinates of the predetermined configuration. The method is based on a geometrical homography and is expedient for robust gaze estimation in connection with e.g.

  • Patent number: 9367127
    Abstract: A control system enables a user to control an electronic device by moving parts of the face, including the eyes. Optical emitters and optical detectors are used to reflect light from the relevant parts of the user's face. Pattern matching or approximation of a pointing location are used to define the control input to the electronic device based on the user's motions. Visual feedback is optionally provided to the user during the controller's actions. Additional sensor elements are optionally provided to improve performance of the system. Hardware and software elements are combined to provide for the specified control actions.

  • Patent number: 9367740
    Abstract: A mobile system for identifying behavior of being physical attracted towards an individual includes a portable computing device carried by a user having at least one camera. For this system, interested individuals are those that exhibit behavioral indications of physical attraction, referred to here as a “check out”. The software includes an individual detector technique, such as infrared, that detects the presence of individuals in the proximity of the device's camera. The software further includes a body position identifier that determines whether an individual detected by the individual detector is facing the portable device. The software further includes a behavior analyzer that analyzes the body and eye movements of an individual detected to determine if the individual has checked out at the user. The computer further includes a recorder that records and counts instances of individuals checking out the user.

  • Patent number: 9361854
    Abstract: A method for stabilization for use in a display system is provided. The method is performed in a first electronic device comprising a first display and a gaze tracking unit configured to track a gaze of a user of the first device. The first device is arranged to send an image signal to the second device. The second device comprises a second display. The method comprises sending the image signal from the first device to the second device, controlling the image signal by the first device, depending on the tracked gaze of the user, displaying the controlled image signal on the second display such that, when the user focuses on an object of a view of the first display, the object of the view on the second display is cropped and stabilized.

  • Patent number: 9329683
    Abstract: A gaze point detection device 1 has four cameras 2a, 2b, 2c, 2d, light sources 3a, 3b, 3c, 3d, control circuits 4, 5, 6, and an image processor 7. The image processor 7 calculates vectors r, each of which is from a corneal reflection point to the center of a pupil, on a plane that is vertical to base lines. The image processor 7 also calculates angles ? of the line of sight on the basis of the vectors r and by using a function f including M parameters. Moreover, the image processor 7 determines the M parameters based on the angles ?, and detects a point of gaze Q based on the line of sight direction calculated using the determined parameters. The number of cameras is set at M×½ or higher.
