			=== VIE-VISU ===
			An interactive glyph technique that is used for time oriented analysis of electronic patient records is '''VIE-VISU''' [Horn et al., 1998]. The motivation for their development was the fact that paper-based analysis of patient records is very hard to conduct because many parameters are involved and an overall assessment of the patient's situation is hard to maintain. The glyph display helps to combine different measurements, maintaining their relationships, show their development over time, and make specific, possibly life threatening situations, easy to spot. The used glyph basically consists of three parts that represent circulation, respiration, and fluid balance parameters (top to bottom). All in all, 15 different patient parameters are combined to form this glyph. Each glyph represents a one hour period and 24 glyphs are combined in a single screen
