20090315827 | GENERATION OF GRAPHICAL FEEDBACK IN A COMPUTER SYSTEM - 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. | 12-24-2009 |
20130169560 | SYSTEM FOR GAZE INTERACTION - 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 unfavourable 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. | 07-04-2013 |
20140043227 | FAST WAKE-UP IN A GAZE TRACKING SYSTEM - 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. | 02-13-2014 |
20140247210 | ZONAL GAZE DRIVEN INTERACTION - A computer system can be controlled with non-contact inputs through zonal control. In an embodiment, a non-contact input that is an eye-tracking device is used to track the gaze of a user. A computer's display, and beyond, can be separated into a number of discrete zones according to a configuration. Each zone is associated with a computer function. The zones and/or their functions can, but need not, be indicated to the user. The user can perform the various functions by moving gaze towards the zone associated with that function and providing an activation signal of intent. The activation signal of intent can be a contact-required or non-contact action, such as a button press or dwelling gaze, respectively. | 09-04-2014 |
20140268054 | AUTOMATIC SCROLLING BASED ON GAZE DETECTION - 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. | 09-18-2014 |
20140310256 | METHOD AND SYSTEM FOR USER INITIATED QUERY SEARCHES BASED ON GAZE DATA - The invention generally relates to computer implemented systems and methods for utilizing detection of eye movements in connection with interactive graphical user interfaces and, in particular, for utilizing eye tracking data to facilitate and improve information search and presentation in connection with interactive graphical user interfaces. A gaze search index is determined based on information that has been presented on an information presentation area and gaze data signals. The gaze search index comprises links between gaze search parameters and presented information that satisfies gaze filter criteria for respective gaze search parameter. A user can initiate query searches for information on the computer device or on information hosts connectable to the computer device via networks by using combinations of gaze search parameters of the gaze search index and non gaze search parameters of a non gaze search index. | 10-16-2014 |
20140354539 | GAZE-CONTROLLED USER INTERFACE WITH MULTIMODAL INPUT - 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 neighbourhood of the current gaze point, as determined based on current gaze data. | 12-04-2014 |
20150058812 | SYSTEMS AND METHODS FOR CHANGING BEHAVIOR OF COMPUTER PROGRAM ELEMENTS BASED ON GAZE INPUT - According to the invention, a method for changing the behavior of computer program elements is disclosed. The method may include determining, with an eye tracking device, a gaze point of a user. The method may also include causing, with a computer system, an interactive event controlled by the computer system to alter its behavior based at least in part on the gaze point of the user. | 02-26-2015 |

20090259762 | DISTRIBUTED AND SCALABLE CONTENT STREAMING ARCHITECTURE - A distributed and scalable content streaming architecture includes a plurality of controllers and a plurality of servers. The controllers are operable to establish Real-Time Streaming Protocol (RTSP) sessions with individual devices. A controller selects a server to provide a requested media stream to a device. The server may be selected based on its proximity to the device, bandwidth availability, or latency characteristics. The server transmits the media stream using a Real-Time Transport Protocol (RTP) and/or a Real-Time Control Protocol (RTCP). A controller can manage a number of sessions many times greater than the number of streams a server can provide, so a controller typically has access to multiple servers. Additional servers can be added to a system without disrupting system operation. | 10-15-2009 |
20090259766 | CLIENT CAPABILITY ADJUSTMENT - Mechanisms are provided to detect device client capabilities associated with screen size, video and audio codec support, bandwidth limitations, and memory limitations. A content server can intelligently select a media stream for transmission to the device using the client capability information for the device. In some instances, the content server presents prioritized selections to a user and the user can choose the optimal media stream. | 10-15-2009 |
20090274437 | EMBEDDING DATA IN MEDIA METADATA TRACKS DURING PLAYBACK - Data is embedded onto new or existing media metadata tracks during playback of a media stream.
