„Walled Spaces for Open Design“ – Grenzerfahrungen aus zwei agilen Software-Migrationsprojekten
No full textDieser Beitrag versucht Grenzen für die Einrichtung eines gemeinsamen
Designraums nachzuziehen, die dem Autor bei der Durchführung zweier ausgewählter
agiler Entwicklungsprojekte aufgezeigt wurden. Die Erfahrungen wurden
aus externer Sicht eines Beraters gesammelt, der sowohl den agilen Prozess mit
eingeführt hat als auch selbst als Softwarearchitekt an der Entwicklung beteiligt
war. Organisationseigene Rahmenbedingungen, das Zusammenspiel der involvierten
Interessensgruppen und die explizierten Ziele der hier beschriebenen Software-
Migrationsprojekte hatten dabei einen wesentlich einschränkenden Einfluss auf
den Freiraum für partizipatives Design. Der Artikel berichtet von aufgetretenen
Schwierigkeiten und beschreibt Lösungsansätze, die dabei verfolgt wurden
Where »less« is »more« – notions of minimalism and the design of interactive systems: A constructive analysis of products & processes of human-computer-interaction design from a minimalist standpoint
No full textThis thesis assumes scientific transdisciplinary work is possible. Consequently, it is torn between a ‚rigid‘ logical tradition, which even in the purely mathematic proof is actually based on convention, empirical ‚evidence‘, that risks choosing chance over truth, and scholarly argument, where generalization is based on the transparency of personal bias. It presents a mixture of scientific work from the liberal arts, from design and from computer science. For some, it will not be detailed enough in its treatment of design, for others, principles of engineering will fall short. Yet, the marriage of different disciplines might appeal to those who believe it is the friction between different fields that makes the craft of designing interactive systems so interesting. This thesis tries to differentiate meanings of simplicity—when we build something, we often want it simple, yet seldom know how. It is a thesis about minimalism, a concept from art, music and literature, and about its use in human-computer interaction. It documents a process rather than presenting a result, as the connection from the liberal arts to computer science is not immediate, and transferring a concept from one realm to another will need some argumentative support to hold the weight of argument. We can well build (fairly) usable interactive systems. Experience tells us how to get things right—most of the time. Guidelines and rules help us to build good interfaces. Design processes, methods and techniques aid us in developing use-centred design. This thesis does not attempt to teach how to design better products in a better way; the author knows others with more practical experience, and is afraid to teach others on this subject. Instead, this thesis establishes perspectives on the why. Why do some products work better than others? Why do guidelines lead to simple designs? Why do methods work? Minimalism is part of this answer. Reduction lies at the heart of design. Identifying key users and key tasks and limiting immediate functionality to the essential produces simple, yet powerful products. Selecting, structuring and modularizing functionality, fitting tools to a specific task, configuring complex work environments, and crafting tools for useful misuse are all important parts of design. Reduction implicitly guides designers, design rules and design methodology. Minimalism is used here to differentiate between these design goals and design activities, it is used as a tool to identify the benefits of reduction, and the trade-offs involved. But it also makes explicit the dangers and shortcomings of an approach following ‚less is more‘, of less becoming a bore
When the journey becomes the destination: Proposing a mindset-based vision to rethink and create multi-modal mobility solutions
No full textThe mobility industry is facing a disruptive transformation. A large number of social, economic and technological trends are shaping the way we will move in the future. In this fast-changing environment, mytaxi becomes FREE NOW due to the joint venture in 2019 between its mother company Daimler together with BMW. While joining forces to become a stronger mobility player, FREE NOW’s product portfolio is undergoing a major change. Moving from offering only taxi rides to becoming a multi-modal mobility provider. This holistic approach to mobility brings lots of new challenges for the company.This project is born from the knowledge gap identified within the company, regarding the city dweller’s behaviours and attitudes. With an open and explorative approach, this project focuses on providing the company with a human-centred upgrade to mobility.Based on a user and trend research, this project identifies how the essence of mobility – of covering a physical distance – will evolve towards a multi-purpose-driven activity: shifting from a compromising experience towards a fulfilling experience.The project, ’When the journey becomes the destination’, identifies four mindsets that describe the interactions city dwellers will have while travelling in the future context. For FREE NOW, the identified potential is to enable people to act according to their state of mind and facilitating them to recognise the mindset they are at that moment. This will allow providing a fulfilling service experience by matching them with the right mobility service.This mindset-based approach proposed aims to help FREE NOW rethink and create multi-modal mobility solutions. While leaving apart the purely functional connotations of mobility, the designed mindsets focus on the meaningful nuances of mobility. From the service experience resulting from the human interactions with the space, four design directions are created to stimulate the designers from FREE NOW to question the status quo, as well as the future context.Strategic Product Desig

Simplifying Annotation Support for Real-World-Settings - a Comparative Study of Active Reading
No full textDespite the multitude of existing interfaces for annotation, little is known about their influence on the created annotations. In this paper, first findings of a comparative video-supported study of active reading are presented. The support for active reading offered by traditional paper-and-pencil vs. two existing annotation tools for the World Wide Web is examined and possible implications for annotation systems are drawn
The Indirect Authoring Paradigm – Bringing Hypertext into the Web
No full textBuilding hypertext systems to provide the required functionality to write hypertexts has always been a goal of hypertext research. The parallel development of hypertext research prototypes and the World Wide Web has resulted in repeated attempts to replace the Web or offer world-wide all-purpose services to augment the Web with "missing" functionality. The paper argues that focusing on the development of tools that offer support to hypertext authors for specific tasks is a necessary first step for the introduction of sophisticated hypertext features into the Web. Following a brief history of interaction with the Web, we demonstrate why authoring tools for the Web are a critical target for efforts to extend the use of hypertexts in the Web. We introduce indirect authoring as a label for a shared characteristic of different approaches that try to reduce the complexity and cognitive overhead involved in authoring hypertext. Drawing on this analysis, we lay out some consequences for hypertext research. We provide pointers to projects that have started to experinment with indirect authoring, and list immediate research questions. Developing a diversity of task-oriented authoring tools to reduce the cognitive overhead for authoring hypertexts could change the face of the Web
