We present a novel control approach to provide programmatically adjustable privacy for sensitive data on directional displays. The method comprises detection and tracking of observers in camera imagery, relating the 2D positions to their 3D position in front of the display, generating the appropriate illumination pattern, and transmitting said pattern to the illumination control unit. The novelty is in the way we choose rules to change the illumination pattern, and that the sensitive data remains visible at near constant brightness for the authorized observer. The system facilitates tracking and reasoning depending on identification of a set of observers. In this work, we discuss the calibration step, head tracking, pattern generation and its dependency on the noise in the observation process, input modalities, and the context based rules for the choice ofthe display modality.
