Design has the wonderful ability to build opportunities from constraints - that’s the bases of it really. And at the end of a project, if you can identify how you’ve made the experience delightful for all types of users, then you’ve done your job properly.
With a ticket machine, you need to think about how it will be used by children, adults, the visually impaired and less-abled users (just to name a few). That’s why we held a Universal Design workshop at the beginning of this project. We needed to identify how to design for all types of users. The human element is the most important aspect of design - that means the product should not only be usable but it should be delightful to use.
And that’s why we refuse to believe that designing in this manner results in a lacklustre or ugly product. That’s the beauty of design. We used the constraint of wheelchair access to form the foundation of the design language. By creating a space for the legs of someone in a wheelchair to access the machine and bringing the area of interaction towards the user, it allowed for the whole design to feel lighter and gave it the iconic arrow profile - these two aspects strongly emphasise movement which is an important thing when designing for public transport.
We worked on the most comfortable height and angle of the screen for all users. The common comfortable reaching zone is where a standing or seated adult does not have to strain in order to reach an interface. The design of our machines accounts for this height and ensures that seated and standing adults are able to reach all areas of the interface comfortably.
We built prototypes in order help identify the ideal angle of the screen. We found that placing the screen at the ideal angle for a standing adult means that persons who are seated will be impacted by glare. This is why we determined that a rotatable screen should be investigated in order to mitigate glare.
