Use an image or chart to present complex information. Provide users better Comprehension.

Cognitive Load Theory Amount of information will affect the level of cognitive load. Excessive amount of information, Have difficulty in learning and understanding. Source: Marcus, 1996 Mental effort Mental load Learning effect

Visual Presentations

Field Experiment Data visualization of Weather information Central Weather Bureau Information Research Design Source: Sweller (1998) &Weng (2001) Questionnaire.

T test one-way ANOVA How the amounts of information impact on information comprehension and cognitive load. How the ways of weather Information presented impact on the information comprehension.

One single piece of information presentation works better than the high amount of information presentation in viewers’ memory. But as of information comprehension, how the data visualization presented matters more.

The high amount of information will be less easy to understand at a glance, because the content of information may trigger more cognitive load. Thus, the single piece of information presented will be a better choice for lower cognitive load for viewers.

The most effective way of visual communication for weather information learning, in our experiment study, was to present simple color Charts. Simple color Charts seem to be the best visual presentation, highlighting substantial information with not too much cognitive load.
