DYSCO Vis.: DYnamic Self-Correction for Obstructed Visualizations

Digital displays are often used to visualize timesensitive, safety-critical data for aviation, automobile, medical, nuclear, and other applications. Such displays represent a potentially dangerous point of failure, because even partial failure or obstruction of such a display (e.g., failure or obstruction of the left-hand side) may result in some or all safety-critical data becoming unreadable. Here, a novel automatic method for dynamically detecting and overcoming certain types of display obstructions or failures is presented. Our method works by displaying machine-readable codes on the display, using a camera to determine any regions in which the codes are not readable (i.e., non-functioning or obstructed regions of the display), and shifting / scaling the visualization to ensure that all safety-critical data is presented only in the functioning, visible regions of the display.
