Conclusions and Future Works
We have introduced the considerations of viewing angle-dependent artifacts in LCDs. An experiment on human factor was mode the importance of off-axis viewing angles. In my thesis proposed using a video camera and face detection software to trace the user’s viewing angle. We have employed a backlight scaling algorithm to enhance the off-axis image quality with minimum power consumption.
We designed an interactive display that can emulate either a field sequential display or a conventional display and can switch to either mode instantly. This apparatus helps the subjects in a psychophysical experiment to detect the spontaneous color breakup artifacts and improves the confidence level of experimental results. We have found that the human vision has much higher sensitivity to sequential stimuli than to simultaneous ones given exactly the same photometrical measures. In addition, to minimize the color breakup artifact, we prototyped an adaptive display that reduces the image chroma on the fly when eye movement is detected by an eye-tracker.
The saccadic color breakup was analyzed in a unified framework followed by a novel experimental platform and technique. The electro-oculogram brain-display interface was introduced to minimize saccadic artifacts for the first time. Saccade-induced color breakup was measured on a saccadic display and a contingent display was designed to minimize color breakup by detecting eye movement with electro-oculogram signals. Beyond the current smart displays that optimize image quality by sensing the ambient environment, we believe that user-aware interactive display is the trend of future display technologies.

We have finished the complete the experimental platform system. Its adaptive backlighting provides a platform for psychophysical experiments of color breakup. We are working on refining the experimental method to collect more reliable data for future modeling.
The human interface of EOG-based system described here relates to a contingent display application and explain our design choices for interactive architecture. The studies of the characteristics of eye–tracking movement, the successful completion of the hardware circuit design to detect signals of eye movement and the sequential color of an integrated LCD system have composed an interactive experimental platform. The experimental results show that in a different viewing angle LCD image quality and color are adjustable; the human-machine interface of the eye movement can capture the attention of people staring at a variety of coordinate locations. These certainly upgrade the performance of viewing angle-aware color correction for LCDs, experimental platform for evaluating and quantifying the color breakup of FSD-LCD, and the high dynamic contrast imaging (HDR).
Beyond the current smart displays that optimize image quality by sensing the ambient environment, we believe that user-aware interactive display is the trend of future display technologies. After applying electrooculogram to color breakup reduction, we are exploring the other modalities including the EEG to improve perceived image quality by sensing the user’s brain activities.
