Discussion

The manifold versions shown above are dominated by pictograms based on some kind of hand luggage (suitcase, case) inside of an outline rectangle plus a key outside.

Studies from several countries present research covering most concepts found in pictogram variants for this referent:

Kraft (1976) and Gärling (1985) examined more than twenty pictogram variants using Appropriateness Ranking Tests. Designs showing hand luggage inside an outline rectangle with a key above were rated as most appropriate while variants similar to the pictograms at the bottom of the table above were placed at the end of the line.

With 78 % correct responses the variant labeled ON Testdesign was superior to the design of Erben/Sramek, which reachend 60 % correct in a Comprehension Test (Brugger, 1977). Responses for the latter variant indicate that the key more often was assigned to the case instead of the locker. The concept showing a key inside the suitcase elicited more erroneous responses like 'Lockable Suitcase', 'Suitcase with Key', 'Suitcase Key'. Further Comprehension Test results indicate that adding a tag to the key seems to be irrelevant (Brugger, 1978).

In a Japanese study to propose domestically unified graphical symbols based on scientific methods, the pictogram variant labeled as Eco-Mo Foundation proved to be understood well enough with a comprehension score of 78.5 (Eco-Mo Foundation, 2001). Among college students the pictogram from Amsterdam Schiphol Airport, with colors inverted and therefore very similar to the AIGA version, reached an outstanding comprehension score of 98.5 (Zwaga & Poppinga).

When Fiori (2008) examined a map symbol showing a key above a case similar to the pictogram labeled as Port on basis of a Comprehension Test, only 53.0 % of the responses were classified as correct. Answers reported are for example: Key-rack, Locksmith, Strongbox, Baggage, Trip, Closet and Baggage Rack.

The variant from the Dutch Railways (labeled NS 1980 above) only reached about 46 % correct responses in a Matching Test with a set of 29 symbols (Zwaga & Boersema, 1983). When asked which sign to follow when looking for luggage lockers, a significant number of respondents selected the symbol presented for Left Luggage instead, as the Dutch Railways symbol for Left Luggage of that time was not very clear, since it displayed just a single suitcase inside a closed rectangle with protruding edges.

Recommendations

Luggage Lockers

Based on test results from research known, we recommend the use of a variant like symbol No 37 of ÖNORM A 3011 part 2.

We further suggest to conduct a Comprehension Test comparing concepts like the first three pictograms of the table above with the design of our recommended symbol.
