Frontline Technology: Head-Mounted-Display Tracking for Augmented and Virtual Reality
Head tracking is a key technical component for AR and VR applications that use head-mounted displays. Many different head-tracking systems are currently in use, but one called ìinside-outî tracking seems to have the edge for consumer displays.</subtit

Frontline Technology: Visible Artifacts and Limitations in Stereoscopic 3D Displays
Stereoscopic 3D (S3D) displays send slightly different images to both eyes and thereby create an additional sense of depth compared to conventional non-stereoscopic displays. Nearly all direct-view S3D displays accomplish this by using either temporal interlacing, which alternates the images of the two eyes in time, or spatial interlacing, which alternates the images on a row-by-row (or column-by-column) basis. The two methods each have limitations, but it is possible to design S3D displays that minimize these.

Frontline Technology: Accurate Image-Based Estimates of Focus Error in the Human Eye and in a Smartphone Camera
Estimation of focus error is a key consideration in the design of any advanced image-capture system. Todayís contrast-based auto-focus algorithms in digital cameras perform more slowly and less accurately than the human eye. New methods for estimating focus error can close the gap. By making use of optical imperfections, like chromatic aberration, these new methods could significantly improve the performance of digital auto-focusing techniques.

Frontline Technology: Quantifying Display Coating Appearance
Modern displays often utilize anti-reflection coatings to enhance contrast and improve readability. However, display manufacturers have unique requirements for coatings not found in other industries. New metrology instrumentation has been designed to obtain the necessary measurements for display makers and to work with the thin glass substrates increasingly employed in display fabrication.
