Following on from the concept workshops, we’ve been busy developing the design for each symbol including a number of options which were tested with groups of people living with dementia.
Concept design phase
Getting into the design we quickly realised there were many different route to explore. After a series of iterations, we developed four options for each symbol to test various factors that could make the symbols more easily understood by people with dementia i.e. showing perspective, including people/figures ‘doing’ the action, shaded flooring.
We considered the styling of the ‘symbol people’ – if they should be ‘morph like’, if they should have necks, or if they should be more human in feature, showing details like clothing and hair. We varied their level of movement, the number of people interacting with each environment, and their activity in each context.
Environments were explored in perspective as well as elevation/straight on, and shading on floors and on objects like toilet seats were visualised to gauge people’s understanding. And we changed the scale on some symbols to see how much information is needed, on close up items like a hand on a door as well as entire rooms and the whole shape of an escalator.
The testing stimulus was prepared as A3 sheets with four options for each symbol alongside the relevant current symbol, and a ‘wash up sheet’ of alternative existing options to help stimulate the discussion. Facilitated by Steve Milton, Director of Innovations in Dementia, these sheets were used to evaluate the legibility and understanding of each of the concepts with groups of people living with dementia across a number of locations. The sessions were recorded and subsequently transcribed.
Testing and feedback
The symbol concepts were tested with 39 people of varying ages and stages of dementia. 33 of these were across five groups and there were six 1-2-1 interviews. Groups were consulted in Shrewsbury, Liverpool, Glasgow, Canterbury and Salisbury. Five interviews took place face-to-face in Stockwell and one via teleconferencing in Salford.
There was an overall enthusiasm from participants to feedback their views on something ‘practical’ rather than policy based that will impact positively on people’s everyday life.
‘Morph’ figure (on the left) was generally preferred as people found it clearer/simpler.
Male / Female / Accessible Toilet
Everyone recognised this as a toilet.
Symbol ‘B’ in perspective with shaded flooring was unanimously preferred and the white figure on black background was least preferred.
Although ‘C’ got the highest number of votes, there was a preference for whole shape
of escalator handrail to differentiate it from stairs. The rounded shape also implies movement which is helpful. The two people interacting with the escalator in ‘A’ and ‘C’ was well liked. Maybe we could develop ‘A’ in 3D with perspective. Many liked the idea of adding an arrow going up, or down for a different version of the symbol, to emphasise the indication of movement.
There was a clear preference for ‘C’ showing perspective noting that the person should be clearly stepping from one space to another, rather than walking past the door. The tree and cloud were identified as representing the ‘outside’ and this was liked, as if moving from one environment to another. The floor shading could be understood better if lower down, so less like the person is in water.
There was a clear preference for ‘D’ showing perspective, doors and shading within lift. There was absolute consensus that the people interacting are important to the understanding of this symbol. There were comments about the button increasing in size!
Everyone recognized the options as stairs. Although ‘B’ got the highest number of votes, there was a preference for whole shape of the staircase as shown in ‘A’. Everyone agreed that the handrail helped them feel reassured.
Almost everyone recognised this as parking and there was a unanimous preference for the simplicity of ‘C’. Some of the options i.e. ‘B’ showed too much information and detail which was confusing for people.
None of the options shown were popular. Concensus was for the original ‘i’ symbol to be retained.
Much discussion was had about whether the symbols represent buying or or showing the ticket. In the end ‘A’ was agreed the most popular.
Symbol ‘C’ was preferred and most people identified this as a seat for people who
need it. It was pointed out that, for example on buses, there is a space reserved for wheelchair users so we don’t need to include the wheelchair access symbol. We need careful development of the wording to support understanding of this symbol.
Symbol ‘C’ was the clear preference because of its simplicity and perspective. The doorway through to another room wasn’t necessary. Everyone found the seated people helpful to the meaning, though they should look less rigid and more active. The clock (with no time shown) could be included as it was popular with most participants.
The perspective of symbol ‘C’ was preferred, with the fire from symbols ‘A/B’. It would make sense to include the outside elements from the previous Exit symbol, as well as movement of the person from one space to another.
Everyone correctly identified this and ‘A’ gained the majority of votes. Some pointed out that the person was controlling their own chair rather than being pushed as in the existing symbol. Some felt an attachment to the existing symbol and questioned whether we need to update the design of the symbol at all.
Most weren’t able to identify any of the options shown but for those who recognised some sort of need, symbol ‘D’ was preferred. Adding colour (red) to the cross at the next design phase may be helpful to the understanding around ‘health’. Careful consideration of the words that support this symbol is needed to aid understanding.
Our next step is to look at the user testing feedback in detail to develop and refine the design of each symbol.
We’ll consider the impact for the user of language and colour – which words that accompany symbols are most easily understood i.e. toilet / restroom / ladies / WC / public convenience.
The trickiest words to consider and resolve will be ‘Priority Seating’ and ‘Hidden Disability’ and we will be working with language strategist Ben Afia https://www.benafia.com to develop some options for testing at the next phase.
We will also consider colour i.e. does a green exit symbol or a blue parking symbol effect its communication?
The design development will lead into the next phase of testing with new groups of people in July.
