Abstract: A method and apparatus are provided for controlling a display device to generate an image for viewing by a user on a display, the image being formed by one or more light having predetermined relative timings. Received image data define one or more light components of a feature to be displayed as an element in the image. Rate data are received, e.g. from an associated tracker system, indicative of a rate of change in orientation of the display relative to a direction of gaze of an eye of the user. The received rate data are used to determine a position on the display for displaying each of the one or more light components of the feature including determining any respective adjustment required to a determined position for the light component according to the received rate data and the predetermined relative timings. The determined position of each of the one or more light components is output to the display device for display of the light component at the respective determined position.

Abstract: A method is provided for determining corrections to rate data output by inertial sensors of a type typically used in tracking changes in orientation of an object. The present invention also extends to a tracker system incorporating the correction functionality of the present invention. The method makes use of rate data output by inertial sensors associated with the object being tracked and rate data derived from measures of orientation supplied by a non-inertial tracker system also associated with the object being tracked and comprises determining from those rate data corrections for errors due to misalignment in rate data output by inertial sensors, by calculating a mapping between vectors linking points in inertial sensor rate space represented by a sample set of received rate data from the inertial sensors and vectors linking points in a derived object orientation rate space represented by a corresponding and synchronised sample set of derived rate data. Corrections for inertial sensor bias may be determined separately from corrections for misalignment-related errors, after correction of inertial sensor rate data for misalignment-related errors by determining the vector translation between a point represented by corrected inertial sensor rate data in the derived object orientation rate space and the point in the same rate space represented by derived rate data synchronised therewith.

Abstract: A method and apparatus are provided for controlling a digital display device to generate an image for display, wherein the display device is arranged to generate the image as an array of pixels each of a defined brightness achieved by emitting a respective combination of light pulses of durations defined according to a predetermined pulse width modulation (PWM) scheme. Whereas, under conventional PWM schemes, each light pulse would be emitted by the same pixel of a display device, in the present invention rate data from an associated tracker system and data defining predetermined characteristics of the display and operation thereof are used to calculate a pixel displacement in respect of each defined pulse of the PWM scheme. The pixel displacement is used to modify control data defining those pixels to be activated to emit the defined pulse such that a different pixel to that intended emits the pulse during relative movement of the direction of gaze of a user's eye and the display apparatus. This has the effect of reducing unwanted display artefacts during such relative movement which are prevalent in conventional digital display systems.
