The thesis purpose is to gather recommendations to adapt participatory design to elderly users, through the involvement of an association of elderly museum volunteers. The outcome is the result of a participatory process that included forms, interviews, cultural probes, and workshops where the volunteers and designer collaborated tightly to explore volunteers’ needs and find solutions to address them. This process led to the design of a platform that empowers volunteers' work and recognizes its value. The platform includes sections managed by the volunteers to archive information about the museum pieces, share organized activities, and receive feedback from visitors to improve their work.

This paper introduces the topic of Cohousing as a solution to the chronic housing crisis and examines how it can be supported by digital platforms, and what form they should take. The theoretical concept of platforms and infrastructure is examined in general and specifically for communities along with other co-operative practices. The methodology of Research through Design (RtD) paired with recognised design methods of interviews, surveys and participatory design including workshops and co-design, employing a design process blending ideation and prototyping with each of these methods. The resulting design is a platform serving the dual functionality of marketing the Cohousing practice to wider society coupled with aggregating the infrastructural and communication needs of a cohousing group. The design works to support a highly interpersonal community-based activity through the face-to-face interaction of groups and demonstrates how the studies of platforms and infrastructure combined with research through design can support such practices.

This Master's degree thesis deals with a specific area of creative industries: development of mobile applications. The aim is to identify and understand the work routines of Czech iOS developers while considering the importance of design as one of the benchmarks of mobile application quality on the Apple App Store. I mainly focus on mapping work routines of selected developers and their thinking about design in the context of Apple devices and iOS platform, assuming that Apple establishes a high standard of visual and functional qualities. I am addressing an issue of application usability not only in terms of design of the user interface, but also its functioning and more aspects of application development within the ecosystem of Czech mobile app industry. The theoretical part of my thesis subjectively describes fundamental concepts from the mobile app development field and theories related to the topic. Empirical part of the study is based on qualitative interviews with 9 Czech mobile app developers and following thematic analysis. This study can serve as an interesting resource of understanding of the work of Czech mobile app developers, how they think about design and Apple as a platform or as a solid foundation for further quantitative investigation to confirm or revise my findings.
