Conference Paper
Senior citizens face challenges during activities in urban space. To help and motivate them pursuing outside activities, we propose a network of (micro and macro) information radiators to increase their feeling of safety. In this paper we first collect guidelines and relevant aspects for the design of micro information radiators. Then we summarize...

During outside activities, elderly people encounter different challenges than young people. Those difficulties impede their motivation to pursue outside activities. To counter this problem from a human-computer interaction perspective, we propose a support system for seniors to improve their motivation and subjective safety while undertaking outsid...
Conference Paper
Im Rahmen des Verbundprojektes UrbanLife+ verfolgen wir einen Gamification-Ansatz, nach dem das spielerische Gestaltungsmittel der Quest als Grundlage dafür verwendet wird, Senioren zur Teilhabe an ihrem urbanen Umfeld zu motivieren, indem ihnen konkrete Vorschläge für Aktivitäten gemacht werden, welche mit einem Belohnungssystem verbunden sind. Da...
Conference Paper
The topic of "playable cities" has recently emerged as a variation on smart cities, focusing on ways to make urban spaces more playfully interactive and fun by incorporating digital technology. Existing work in this field has largely focused on explorative design and case studies. As of yet, there are barely any design guidelines specific to the co...
Conference Paper
Building upon work by Perrig & Song, we propose a novel hash visualization algorithm and examine its usefulness for user-governed password validation in real time. In contrast to network-based password authentication and the best practices for security which have been developed with that paradigm in mind, we are concerned with use cases that requir...
Poster
Existing research into user engagement with public displays tends to focus on aspects of visual and interaction design, with less thought given towards how the choice of content may influence user behavior. In this article, we survey the existing literature, particularly deployment studies of public displays, for lessons learned on the ramification...
Conference Paper

Seniors face many challenges in their daily activities regarding mobility and accessibility. We have designed and prototyped a system of networked public displays to support them, particularly regarding outdoor pedestrian navigation. This article describes the process and results of a qualitative evaluation of this prototype system, which was condu...

Designing human-computer interaction for non-personal computing devices in urban space poses different challenges than designing for personal devices. In this paper we summarize the findings from a project developing smart urban objects to help elderly people participate in urban life. We present four key challenges that have been identified design...

Die Selbstbestimmung älterer Menschen wird wesentlich davon bestimmt, sich sicher in ihrer jeweiligen Umgebung bewegen zu können. Nachlassende Fähigkeiten zur Interaktion mit der Umgebung schränken die soziale und kulturelle Teilhabe Älterer jedoch ein bis hin zur sozialen Isolation. Hier eröffnen Methoden der Mensch-Technik-Interaktion (MTI) vielf...
Article
Full-text available
Developers and designers of interactive digital systems are faced with many challenges, some less visible than others. One of these more subtle balancing acts is between personalized user support and unrestricted user autonomy. It raises the question how a supportive design that takes a user’s needs and preferences into account can be implemented w...
Conference Paper
Full-text available
The irreversible process of demographic change, especially in Germany, leads to numerous challenges. According to this, research has to face the task to integrate the constantly ageing population into the urban and public space in such a way that there are as few barriers as possible. With the support of digitalization, so-called smart urban object...
Conference Paper
Information radiators are ubiquitous stationary installations that radiate information that is likely to improve awareness of passers-by in semi-public environments like organization floors. In this paper, we present the idea of using several kinds of information radiators for enhancing urban participation of seniors - by providing awareness for su...
Conference Paper
We present findings from an interview-based study of the pervasive mobile multiplayer game Ingress. Our study focuses on how boundaries between (1) everyday life and play and (2) 'real' and game space blur in pervasive gaming. We present findings on how the game is integrated into everyday life and affects players' mobility patterns, and on how pla...
Conference Paper
Changing life in urban areas creates challenges for people who move and also for long-term inhabitants, who have to orientate themselves in new or changing environments. ICT has the potential to support people in orientating in urban neighborhoods as well as to foster participation when it comes to shaping future life in cities. We present results...
Conference Paper
Full-text available
Der urbane Raum wird zunehmend intelligenter. So können Passanten mit Druckknöpfen an Ampelanlagen spielen, um die Rotphase zu überbrücken, Informationstafeln an Bushaltestellen zeigen Verspätungen des Busses an und WLAN-Technologie erlaubt das Erfassen der Bewegung unterschiedlicher Akteure im Raum. Die Vorteile aus dieser Vernetzung, stehen jedoc...
Thesis
Full-text available
Virtual agents are constructs that fulfill human or human-like roles in virtual environments, but are directly controlled by software instead of real humans. They have use cases such as presenting information, demonstrating actions or simulating a social environment. If a real person perceives them as sufficiently human-like, they may induce social...

In der Lehre zur MCI (Mensch-Computer-Interaktion) stellt sich immer wieder die Herausforderung, praktische Übungen mit spannenden Ergebnissen durchzuführen, die sich dennoch nicht in technischen Details verlieren sondern MCI-fokussiert bleiben. Im Lehrmodul „Interaktionsdesign“ an der Universität Hamburg werden von Studierenden innerhalb von drei...

Gamification, der Einsatz von Spielmechaniken in spielfremdem Kontext, ist ein Trend, der bei Unter-nehmen Beachtung findet und Interesse weckt Aspekte davon unternehmensintern einzusetzen. Dem-gegenüber besteht jedoch auch Skepsis, da ein spielerischer Ansatz im Bezug auf Geschäftsszenarien bisher unüblich ist und dessen langfristiger Erfolg bisla...

Gegen Ende der Schullaufbahn stellt sich bei vielen Schülern verstärkt das Bewusstsein ein, dass die Zeugnisnoten (insbesondere der Abiturschnitt) einen starken Einfluss auf ihre Karrieremöglichkeiten haben. Die Gesetze und Regeln, nach denen die Punktzahlen miteinander verrechnet werden, sind jedoch komplex und für viele Schüler undurchsichtig. In...

Teachlets als innovative Lehrmethode befinden sich seit 2004 im Praxiseinsatz, Literatur ist zum Thema allerdings kaum vorhanden und nicht auf dem aktuellen Stand. In dieser Arbeit wird die Teachlet-Praxis der letzten Jahre resümiert, die bisherige Definition des Begriffs auf ihre Zukunftsfähigkeit untersucht und erweitert, aktuelle Entwicklungen d...
