Abstract

Around 252 million trips by public transport are taken in Helsinki every year, and about 122 million passengers travel by Helsinki City Transport (tram, metro and ferry) in and around Finland's capitol. Given these numbers, it is important that the system be as wholly efficient, inclusive, and as easy to use as possible. In my master's thesis, I examine Helsinki Region Transport's ticketing and information system. I pay special attention to their new touch screen card readers, framing them in the context of increasing usability and accessibility through the use of sound design. I look at what design decisions have been made and compare these with a variety of available technology that exists today, as well as what solutions are being used in other cities. Throughout my research, I've placed an emphasis on sonic cues and sound design, as this is my area of study. Everything is assessed against the requirements and perspective of Helsinki's public transportation end users who are blind and visually impaired. I have used desk research, field research, user testing and stakeholder interviews in my methodology. I have put forth suggestions on how to improve the current system, taking into account the learnings from my research. I have looked at key points around people with disabilities and how sound can be used to improve accessibility and general functionality for all. I also hope to share this thesis with HSL and HKL, whom may use it to inform future optimization of their systems.
