A method for applying adapted colour rendering in relation to intensity of light of wavelengths relevant to the circadian rhythm of a user, a computer program, a carrier, a system and a head-mounted device is disclosed. The method comprises receiving gaze tracking information identifying a gaze vector of the user of the system, and determining a respective location of a first area of the display and a second areas of the display based on the identified gaze vector. A first colour rendering mode is applied in the first area of the display, and a second colour rendering mode is applied in the second area of the display. The first colour rendering mode and the second colour rendering mode differ in relation to a degree of selective adaptation of intensity of light of wavelengths relevant to the circadian rhythm of the user.

The invention is related to a method for driver alertness detection, The method comprises the steps of determining a vanishing point of a vehicle in motion; determining over time, by an eye tracking device, a set of gaze points of the driver of the vehicle; determining a gaze movement from the set of gaze points; and identifying an alertness of the driver, based on a direction of the gaze movement relative to the vanishing point being outward. Further, the invention is related to an eye tracking device for driver alertness detection, an alertness detection system, a computer program, and a computer-readable medium.

Driver alertness detection method, device and system

Techniques for changing the presentation of information on a user interface based on presence are described. In an example, a computer system determines, based on an image sensor associated with the system, a first presence of a first user relative to a computing device. The computer system also determines an identifier of the first user. The identifier is associated with operating the computing device. The operating comprises a presentation of the user interface by the computing device. The computer system also determines, based on the image sensor, a second presence of a second person relative to the computing device. The computer system causes an update to the user interface based on the second presence.

Protection of and access to data on computing devices

A head mountable arrangement assists a subject to acquire spatial information about a surrounding environment by receiving gaze data from an eyetracker and spatial data from a distance sensor respectively. The gaze data describe an estimated point of regard of the subject, and the spatial data describe a distance between a reference point and an object in the surrounding environment. A feedback signal is provided, which indicates a distance from the subject to said object in the surrounding environment. The feedback signal is generated based on the estimated point of regard and the spatial data, and may reflect the distance to a surface element of an object that intersects a straight line between an eye-base line of the subject and the estimated point of regard, which surface element is located closer to the eye-base line than any other surface element of the objects in the surrounding environment along said straight line.

A method and a corresponding apparatus for mitigating motion sickness in a virtual reality VR/augmented reality (AR) system using a head mounted display (HMD) are disclosed. The method comprises receiving data from a sensor indicating a current orientation of the HMD in real space, and superimposing a visual indication on a display of the HMD. The visual indication provides visual information to a user of the current orientation of the HMD in real space. Furthermore, methods and corresponding apparatuses are disclosed of calculating gaze convergence distance in an eye tracking system, and of gaze based virtual reality (VR)/augmented reality (AR) menu expansion.

Eye tracking applications in virtual reality and augmented reality

Techniques for interacting with a first computing device based on gaze information are described. In an example, the first computing device captures a gaze direction of a first user of the first computing device by using an eye tracking device. The first computing device determines if the gaze direction of the first user is directed to a first display. Further, the first computing device receives information regarding if a gaze direction of a second user is directed to a second display. If the gaze direction of the first user is directed to the first display and the gaze direction of the second user is directed to the second display, the first computing device continuously updates content on the first display. If the gaze direction of the second user is not directed to the second display, the first computing device pauses the content on the first display.

Techniques for data sharing between two computing devices are described. In an example, a computer system determines a first presence of a first user relative to a first computing device. The computer system also determines a first identifier of the first user. The first identifier is associated with operating the first computing device. The operating comprises sharing data with a second computing device. The computer system also determines a second presence of a second user relative to the second computing device. The computer system also determines a second identifier of the second user. The second identifier associated with operating the second computing device. The computer system cause the data to be shared with the second computing device based on the first presence, the first identifier, the second presence, and the second identifier.

Techniques for interacting with a first computing device based on gaze information are described. In an example, the first computing device captures a gaze direction of a first user of the first computing device by using an eye tracking device. The first computing device displays a representation of a second user on a display of the first computing device. Further, the first computing device receives from the first user, communication data generated by an input device. The first computing device determines if the gaze direction of the first user is directed to the representation of the second user. If the gaze direction of the first user is directed to the representation of the second user, the first computing device transmits the communication data to a second computing device of the second user.
