Abstract: A gaze tracking system, leaving a low power mode in response to an activation signal, initial burst of eye pictures in short time by restricting the image area of a sensor, purpose of enabling an increased frame rate. Subsequent eye pictures are captured at le rate. The first gaze point value is computed memorylessly based on the initial burst res and no additional imagery, while subsequent values may be computed recursively to 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 different sensor. From the gaze point values, the system may derive a control signal to a computer device with a visual display.

An example method to distribute a media stream over a distribution network to a number of devices may include determining, by one or more computer processors coupled to memory, a common master-client shared time reference Tref. Example methods may include determining a mean intermediate arrival time for first packets of a first type of the media stream, determining respective first playout times for the first packets based on the mean intermediate arrival time and the time reference Tref, associating the first packets with the respective first playout times, and distributing the media stream to the plurality of devices.

Abstract: 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.

Abstract: The present invention relates to control of a computer system, which includes a data processing unit, a display and an eye tracker adapted to register a user's gaze point with respect to the display. The data processing unit is adapted to present graphical information on the display, which includes feedback data reflecting the user's commands entered into the unit. The data processing unit is adapted to present the feedback data such that during an initial phase, the feedback data is generated based on an absolute position of the gaze point. An imaging device of the system is also adapted to register image data representing movements of a body part of the user and to forward a representation of the image data to the data processing unit. Hence, during a phase subsequent to the initial phase, the data is instead generated based on the image data.

Abstract: Disclosed are various embodiments for automatic scrolling of content displayed on a display device in response to gaze detection. Content may be displayed in a window rendered on a display screen. Gaze detection components may be used to detect that a user is gazing at the displayed content and to determine a gaze point relative to the display screen. At least one applicable scroll zone relative to the display screen and a scroll action associated with each applicable scroll zone may be determined. In response to determining that the gaze point is within a first applicable scroll zone, an associated first scroll action may be initiated. The first scroll action causes the content to scroll within the window until at least one of: expiration of a defined period, determining that a portion of the content scrolls past a defined position within the window, determining that the gaze point is outside of the first scroll zone, and detecting an indicator that the user begins reading the content.

Abstract: A method for panning content on a display of a wearable device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include determining, via a movement detection system, a head direction of the user. The method may further include, based at least in part on the gaze direction and the head direction both being consistent with a particular direction, causing content displayed on a display of the wearable device to be panned in the particular direction. The method may additionally include determining during panning of the content, via the eye tracking device, that the gaze direction of the user has returned to a neutral position. The method may moreover include, based at least in part on the gaze direction of the user returning to the neutral position, causing content displayed on the display to stop panning.

Abstract: A personal computer system provides a gaze-controlled graphical user interface having a bidirectional and a unidirectional interaction mode. In the bidirectional interaction mode, a display shows one or more graphical controls in motion, each being associated with an input operation to an operating system. A gaze tracking system provides gaze point data of a viewer, and a matching module attempts to match a relative gaze movement against a relative movement of one of the graphical controls. The system includes a selector which is preferably controllable by a modality other than gaze. The system initiates a transition from the unidirectional interaction mode to the bidirectional interaction mode in response to an input received at the selector. The display then shows graphical controls in motion in a neighborhood of the current gaze point, as determined based on current gaze data.

Abstract: There is provided a method and corresponding node and system for playout buffering and retransmission which can handle Over-The-Top (OTT) and Video-On-Demand (VOD) distribution to a large number of client devices, e.g. a server serving a number of client devices with e.g. the same TV-channel. The presented method comprises transmitting a data stream DS from a server 101 to at least two client devices 151-153, where a predetermined portion of client shared data of the data stream is buffered in a shared buffer. Upon receiving per client requests for retransmission of data from the client devices, requested data is retrieved from the shared buffer and retransmitted to the requesting client device. The method further comprises removing buffered data from said shared buffer based on if a time of interest for the buffered data has passed. The inventive concept is applicable in distribution of e.g. media data as in typical OTT and VOD, which is transported over unicast.
