摘要： Head pose information may be determined using information describing a fixed gaze and image data corresponding to a user's eyes. The head pose information may be determined in a manner that is disregards facial features with the exception of the user's eyes. The head pose information may be usable to interact with a user device.

摘要： According to the invention, an image sensor is disclosed. The image sensor may include a plurality of pixels. Each pixel of a first portion of the plurality of pixels may include a near-infrared filter configured to block red, green, and blue light; and pass near-infrared light. Each pixel of a second portion of the plurality of pixels may be configured to receive at least one of red, green, or blue light; and receive near-infrared light.

摘要： According to the invention a system for authenticating a user of a device is disclosed. The system may include a first image sensor, a determination unit, and an authentication unit. The first image sensor may be for capturing at least one image of at least part of a user. The determination unit may be for determining information relating to the user's eye based at least in part on at least one image captured by the first image sensor. The authentication unit may be for authenticating the user using the information relating to the user's eye.

摘要： A method and system for assisting a user when interacting with a graphical user interface combines gaze based input with gesture based user commands. A user of a computer system without a traditional touch-screen can interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. A solution for touch-screen like interaction uses gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen. Combined gaze and gesture based interaction with graphical user interfaces can be used to achieve a touchscreen like environment in computer systems without a traditional touchscreen or in computer systems having a touchscreen arranged ergonomically unfavorable for the user or a touchscreen arranged such that it is more comfortable for the user to use gesture and gaze for the interaction than the touchscreen.

摘要： A system for determining a gaze direction of a user of a wearable device is disclosed. The system may include a primary lens, an illuminator, an image sensor, and an interface. The illuminator may include a light guide, may be disposed at least partially on or in the primary lens, and may be configured to illuminate at least one eye of a user. The image sensor may be disposed on or in the primary lens, and may be configured to detect light reflected by the at least one eye of the user. The interface may be configured to provide data from the image sensor to a processor for determining a gaze direction of the user based at least in part on light detected by the image sensor.

摘要： A computer system can be controlled with non-contact inputs, such as eye-tracking devices. A computer can enlarge a portion of a display adjacent a first gaze target in response to detecting a first action (e.g., pressing a touchpad). The computer can then allow a user to position a second gaze target in the enlarged portion (e.g., by looking at the desired location) and perform a second action in order to perform a computer function at that location. The enlarging can allow a user to identify a desired location for a computer function (e.g., selecting an icon) with greater precision.

摘要： According to the invention, a system for converting sound to electrical signals is disclosed. The system may include a gaze tracking device and a microphone. The gaze tracking device may determine a gaze direction of a user. The microphone may be more sensitive in a selected direction than at least one other direction and alter the selected direction based at least in part on the gaze direction determined by the gaze tracking device.

摘要： Methods and systems are disclosed for assisting a user using a system including an eye tracker and a device, the device being configured to be worn on a limb of the user or held in the hands of the user. The methods and uses of systems disclosed include the steps of (1) tracking the user's gaze direction in a real world environment and determining a real world object, subject, or item the user is currently focusing on based on the user's gaze direction; and (2) providing information and/or an option to adjust at least one parameter, preferably via the device, based on the identified real world object, subject or item.

摘要： A gaze tracking system, leaving a low power mode in response to an activation signal, captures an initial burst of eye pictures in short time by restricting the image area of a sensor, with the purpose of enabling an increased frame rate. Subsequent eye pictures are captured at normal frame rate. The first gaze point value is computed memorylessly based on the initial burst of eye pictures and no additional imagery, while subsequent values may be computed recursively by taking into account previous gaze point values or information from previous eye pictures. The restriction of the image area may be guided by a preliminary overview picture captured using the same or a different sensor. From the gaze point values, the system may derive a control signal to be supplied to a computer device with a visual display.
