Use visual representations where they can explain better than words, or where they aid understanding

writingBut beware that pictures, tables and graphs can cause confusion and send out the wrong messages. Visual representations should be user tested. See the section of ‘involving users’ for more information and resources about how to do this.

Why is this important?

Visual displays can be a powerful tool to convey health-related statistical information… However, some caution is warranted as visual displays may not be intuitively understood by everyone… Overall, all visual aids should be pilot tested for understanding (not simply preferences), and developers should take care to avoid using misleading images (such as graphs with misleading scales).

The pictograms for the 10 different instructions and warnings showed great variation in interpretation rates...Pictograms have the potential to help patients understand information on drug therapy. This study shows that some existing pictograms are not easily interpreted and that testing is needed before their implementation.
