摘要： A method of presenting visual information on a screen (306) involves defining a boundary (314) delineating a first region of the screen (which may be towards a centre of the screen) from a second region of the screen (which may be towards a periphery of the screen), displaying a first portion of the visual information in the first region of the screen at a first display quality, and displaying a second portion of the visual information in the second region of the screen at a second, lower, display quality. The method further involves blurring the visual information for display in at least a portion of the second region. The location of the boundary (314) may change over time, and may be based on where a user is looking, or is expected to be looking, or on the type of information being displayed or based on other parameters.

摘要： Sensor information is received (S41) at a host device from a mobile device. A pose of the mobile device is then determined by the host device based on the received sensor information. The pose of the mobile device is compared with pose information (S42) of previous poses of the mobile device, each previous pose of the mobile device being associated with a performance level of the system for data transmitted from the host device and received and output at the mobile device having that previous pose. The host device then determines (S43) whether a performance level of the system for the mobile device having the determined pose is likely to be above or below a threshold of acceptability based on the comparison, and, if it is determined that the performance level is likely to be above the threshold of acceptability, setting (S44A) a low level of compression to be applied to the data so that quality of the data transmitted to the mobile device is high, but, if it is determined that the performance level is likely to be below the threshold of acceptability, setting (S44B) a high level of compression to be applied to the data so that quality of the data transmitted to the mobile device is low, but is more likely to be received and output properly by the mobile device.

摘要： A method for processing data for display on a screen involves encoding, using a first colour space, a first portion of image data intended to be displayed on a first area of the screen and encoding, using a second colour space, a second portion of image data intended to be displayed on a second area of the screen. The encoded first and second portions of the image data are compressed, and transmitted over a link for display on the screen. By using different colour spaces to encode image data that is displayed in different parts of a screen, differences in a users vision and/or aberrations caused by display equipment may be accounted for and so provide an improved user experience. Using different colour spaces for different screen areas may also reduce the amount of data that needs to be transmitted, for example by encoding image data more effectively and/or allowing more efficient compression of data.

摘要： In virtual-reality display devices it is possible to use head movement as an input to compression, which assumes that the user is looking at something that is moving at approximately the same rate in the same direction as the user's head. This method determines whether an eye of a user of a head mounted display is directed at a relatively fixed point. The method involves detecting (S51) a movement of the user's head, including a lack of movement thereof, determining (S53) a direction of the movement of the user's head, detecting (S52) movement of at least one eye of the user, including a lack of movement thereof, and determining (S54) a direction of the movement of the user's eye. If the directions of movement of the user's head and at the user's eye are different (S55), within a predetermined threshold, it can be assumed that the user's eye is directed at a fixed point (S57), whereas if the directions of movement of the user's head and the user's eye are not different (S55), within a predetermined threshold, then it can be assumed that the user's eye is not directed at a fixed point (S56).
