User requirement analysis for a railway ticketing portal with emphasis on semantic accessibility for older users

In this paper, we present the results from a survey on user requirements for older users of online ticketing services of a nationwide railway ticket and travel information portal. Our survey shows that older users differentiate in their attitude towards internet according to their experience with internet services and the service provided, not only according to their age. Further, our study indicates that in contrary to common belief advertisement or interactive elements are not perceived as negative all the time. The results of a questionnaire with 1200 responses, focus groups, interviews and qualitative analysis of user feedback also indicate that in order to improve and optimize the usage of the online system for older adults, it is needed to supply the system not only with technical accessibility requirements but also with an understanding of universal accessibility requirements. Universal requirements are defined by real user and usage cases and they consider standardization on not only coding but also predictability of usage and same patterns of interaction for similar websites.
