“…Early public transportation services only provided predictive information that users would arrive at a station at a fixed time for the service hours of subways and buses. As smart devices began to spread rapidly, public transportation service applications based on smart devices, such as SCOTTY in Austria [7], NextStop [8], and TransitTimes+ [9] in the United States, provided operational information.…”

Currently, many people enjoy videos and music content through their smart devices while using public transportation. However, because passengers focus so much on content on their smart devices, they sometimes forget to disembark and miss their destination stations. Therefore, in this paper, we propose an application that can notify users via smart devices when they approach the drop-off point in public transportation using an inaudible high frequency. Inaudible frequency signals are generated with announcements from speakers installed on subways and city buses. Smart devices receive and analyze the signals through their built-in microphones and notify users when they reach the drop-off point. We tested destination notifications with the proposed system and 10 smart devices to evaluate its performance. According to the test results, the proposed system showed 99.4% accuracy on subways and 99.2% accuracy on city buses. Moreover, we compared these results to those using only subway app in subways, and our proposed system achieved far better outcomes. Thus, the proposed system could be a useful technology for notifying smart device users when to get off public transport, and it will become an innovative technology for global public transportation by informing users of their desired stations using speakers.

“…A second way to convey that message is to play one auditory icon, e.g., the sound of an automobile running poorly, followed by another auditory icon, e.g., the sound of a computer. The combination of two different sonifications is sometimes referred to as concatenation, which has been implemented with auditory icons (Kostiainen, 2011) as well as other sonifications (Blattner et al, 1989).…”

Auditory icons are naturally occurring sounds that systems play to convey information. Systems must convey complex messages. To do so, systems can play: 1) a single sound that represents the entire message, or 2) a single sound that represents the first part of the message, followed by another sound that represents the next part of that message, etc. The latter are known as concatenated auditory icons. To evaluate those approaches, participants interpreted single and concatenated auditory icons designed to convey their message well and poorly. Single auditory icons designed to convey their message well were correctly interpreted more often than those designed to convey their message poorly; that was not true for concatenated auditory icons. Concatenated auditory icons should not be comprised of a series of sounds that each represents its piece of a message well. The whole of a concatenated auditory icon is not the sum of its parts.

“…However, one prerequisite is either working indoor positioning or beacons, which can provide proximity measures. The previous projects [22,23] at the Institute Integriert Studieren already considered this topic in the context of public transportation and could reuse this as solid basis for further work.…”

Providing information in 'easy-to-read' aims at improving accessibility through easier understandable text which is more appropriate for different target groups. Particularly, legal notifications are often hard to understand. This paper presents an app and its' underlying online system that enables users to read such information, adapted to their individual reading skills. The online system allows creating and managing translations of complex information of notifications. It maps a three-step process of translation including stakeholders located at different institutions on a content management system, which provides information of scalable complexity in terms of language level and level of detail. Users use their personal mobile devices to access this information. The app is used to identify documents with the built-in QR-code reader utilizing the back-facing camera of the smart device. After identification of this specific instance of the document, the app fetches the information, including personal data, and presents it at the user-preferred language level. Privacy and security issues were considered as well as requirements necessary to ensure accessibly.
