Abstract: A luminous display includes pixels arranged in rows and columns. Control signals that are used for controlling first switches for measuring parameters of pixel cells in a first row are also used to control second switches for programming pixel cells in a second row. In this way it is possible to use a single control signal for selecting one pixel cell for programming and simultaneously selecting another pixel cell for measuring. Programming and measuring are thus performed in a time staggered manner, while the addressing is moved to the respective next row. The programming is preferably voltage programming. In one embodiment the current through the pixel cell that is currently programmed is interrupted. In another embodiment the measuring is performed only after the transient current into signal holding means coupled to current control means has set.

Abstract: Methods for enabling hands-free selection of virtual objects are described. In some embodiments, a gaze swipe gesture may be used to select a virtual object. The gaze swipe gesture may involve an end user of a head-mounted display device (HMD) performing head movements that are tracked by the HMD to detect whether a virtual pointer controlled by the end user has swiped across two or more edges of the virtual object. In some cases, the gaze swipe gesture may comprise the end user using their head movements to move the virtual pointer through two edges of the virtual object while the end user gazes at the virtual object. In response to detecting the gaze swipe gesture, the HMD may determine a second virtual object to be displayed on the HMD based on a speed of the gaze swipe gesture and a size of the virtual object.
