Discussion

Almost all pictograms found show a side view of human figure diving head first into water. Differences mostly are based on the phase displayed: in several images the first phase of diving is shown by indicating a starting dive posture, while many other pictograms show the moment just before entering the water. Some images show the edge of a pool, and a few also indicate a diving board. As usual the rendering of the water surface is an element exhibiting the individual style of a uniformly designed system.

Several of the pictogram examples shown in the table above are not intended for the message Diving, but for Swimming Pool, which again usually is indicated by the pictograms for the referent Swimming. If a clear differentiation between Swimming, Swimming Pool, and Diving is possible, and there also is a need for separate pictograms, all three should be designed in such a way that confusions are minimized.

All research papers found related to this referent have a focus on the hazard related to diving, and symbols or signs examined are all for the message No Diving. No explicit test data on comprehensibility of pictograms used to signify the activity of diving is available in our database, but some information concerning comprehensibility exists for one pictogram: as the Parks Canada pictogram No 6-4-203: Diving displayed above has the status Retired in the corresponding source document, this variant seems not to have reached a comprehension rate of 60 %.

Recommendations

We suggest to compare all concepts available to identify the best image content. The study design should also include a Comprehension Test to identify possible misinterpretations. Detailed information about the most frequent responses given in each of the response categories should be provided to correctly judge comprehensibility and improve designs. On such a basis a clear decision concerning a specific recommendation can be reached.
