[comp.graphics] Temporal Displays

sbc@wucs1.wustl.edu (Steve B Cousins) (12/15/88)

Does anyone have any pointers to work on the display of temporal
information?  I've been trying to compile a list of different
display methods to use in building a front end to a temporal reasoning
system.  For example, calendars are one way to display time, and
time lines (like you see in history books) are another.  I guess
some people must have looked into this, but I haven't been able
to find any references so far.

Thanks in advance.

For time-series data, you might be interested in a dynamic display
my colleagues and I have been investigating.

	Dynamic Representation of Multivariate Time Series Data
	J.J.Mezrich, S.P.Frysinger, and R.Slivjanovski
	J. of the American Statistical Assocation Vo.79/Num385
	March 1984

We used auditory and visual displays to represent each time sample
of the time series, and "played" the resulting "frames of data" in
sequence to display the whole time series.  Among other interesting
aspects of this display (especially the use of sound), it allowed
the data analyst to
	- vary the speed of the display
	- vary the direction of the display (forward or back in time;
		they don't sound/look the same!)
	- augment individual variables (through color and timbre)

Hope this helps!
