A method for operating a display of a virtual reality or augmented reality headset includes determining a direction of movement of a user's eye, estimating a future gaze direction from the determined direction of movement, and rendering an image on the display having higher resolution image data in a region including the estimated gaze direction and lower resolution image data outside of the region including the determined gaze direction. The determining the direction of movement of the user's eye includes illuminating the user's eye with a beam of light emitted by a first laser, receiving, at the first laser, light redirected from the user's eye_such that self-mixing interference occurs within the laser cavity between light generated by the first laser and the light redirected from the user's eye, measuring the self-mixing interference, and determining a direction of movement of the user's eye-from the measured self-mixing interference.

Eye movement determination

A rotary encoder for providing a control signal in dependence upon an angular position of a controller rotatable about an axis of rotation. The rotary encoder includes a component for rotation with said controller about said axis of rotation. The rotary encoder also includes a radiation source and detector arrangement configured to direct radiation towards a target region and generate a detector signal dependent upon radiation reflected from within that target region. The rotary encoder further includes a computer processor configured to process said detector signal to determine a measure of distance or change of distance to a reflecting surface region within said target region, and to use said measure to provide said control signal. The component defines a reflecting surface that passes through said target region such that a reflecting surface region is present within said target region with a distance that varies with the angular position.

Rotary encoders

An optical device includes a display and an optical sensor. The display includes display circuitry. The optical sensor is arranged behind the display. The optical sensor includes an emitter for emitting light through the display and a receiver for receiving light reflected back through the display. An absorption of the display is wavelength dependent and the absorption of the display is 50% at a first wavelength. The emitter is configured to emit light at a second wavelength greater than the first wavelength.
