	~~== References ==~~		Oh My goodness!!! I was lonkiog for some simple patterns for me and my older daughter at our local fabric store and they had these, I should have known they were by Mrs. Liesl! Thank you, Mrs. Liesl, these patterns are so great and very clean and classic. Thank you, Thank you, Thank you!!! Luv you and your talent! To know that I just discovered you for my baby girl was great enough but this is a cherry on top ( jumping joyfully) wohoooo!!!!

== Summary ==

== Category ==
Interaction

== Context ==
The data is represented in such a way that the entire dataset cannot be
viewed at one time. However, the user has a mechanism for spatial
movement from one part of the dataset to another. Alternatively a large
number of data items captured frequently over a period of time are being
viewed using animation.

== Problem ==
How to maintain the users context when travelling through the data
space.

== Forces ==
* Need to maintain context in data space.
* Moving from one part of the dataset to another.
* Looking for changes in data over time.

== Solution ==
'''Use smooth animation and motion. This is especially true for
temporal data.'''

Animation or motion is an effective means of representing data that has
some temporal aspect. The most important consideration when using this
technique is to make the transition from one state to another as smooth
as possible. Animation or motion that produces a large change of state
distracts the user from the information and may cause important features
to be missed. Large jumps from one location in a 3D environment to
another may cause the user to become disoriented a smooth transition
helps them to maintain their context in the environment. If possible the
user should be able to control the rate of change and direction of the
animation, this may allow them to rapidly and accurately explore the
data.

There are arguments for not using smooth animation or motion. If the
task is to monitor data that may change only gradually over long periods
of time, then using large discrete time steps may help the user to identify
significant changes in the data. This implies that the application of this
pattern may be task dependent.

Note it is difficult to find examples since researchers tend not to describe
the rate at which transitions occur.
