Effects Of Flat Panel Display Parameters Across Three Application Areas Upon Similarity Judgments, Novia Weiman
Effects Of Flat Panel Display Parameters Across Three Application Areas Upon Similarity Judgments, Novia Weiman
Dissertations and Theses
A human performance experiment was conducted to investigate pixel parameter requirements for three types of flat-panel display images: an alphanumeric character, an oscilloscope waveform, and a real-world image. Subjects performed similarity judgments between an extremely high-quality image and an image composed of different levels of anti-aliasing and pixel width-plus-pixel separation (pitch). It was found that the effect of pitch had greater influence on perceived image quality for the alphanumeric character and oscilloscope waveform than for the real-world image. The results of this research provide empirical evidence showing that the pixel pitch requirements for flat-panel systems that are used to display …
Eye Contact Perception At Distances Up To Six Meters, Daniel L. Scarl
Eye Contact Perception At Distances Up To Six Meters, Daniel L. Scarl
Dissertations and Theses
Common experience suggests that most people can tell whether they are being looked at by another person who is about 8 m away. However, the results of past experiments, which used distances of no more than about 3 m, have implied that this cannot be done if the person looked at (Receiver) judges only by the iris-sclera configuration of the person looking (Sender). This is true even if eye contact is defined simply as identifying on-face gazes (FGs). It has been suggested that in everyday experience eye contact is accompanied by cues other than iris position, and that these non-iris-position …
