A transformational product to improve self-control strength: the chocolate machine

Flavius Kehr; Marc Hassenzahl; Matthias Laschke; Sarah Diefenbach

Lack of self-control is at the heart of many undesirable behaviors, such as overeating, overspending, and even overworking. While the field of Persuasive Technologies searches for ways to change attitudes and behaviors, it often neglects the science of self-control. We present the Chocolate Machine, an exploratory interactive product to train self-control strength based upon Ego Depletion theory. A field study showed the machine to increase perceived self-control over time, while providing a sustained positive experience. This makes the machine transformational, aiming at facilitating behaviors people find worthwhile, but hard to implement.

Designing for well-being: A case study of keeping small secrets

Sarah Diefenbach; Marc Hassenzahl; Kai Eckoldt; Lena Hartung; Eva Lenz; Matthias Laschke

Abstract To a good part, well-being depends on individual engagement in beneficial activities. The present paper draws attention to the potential of encouraging and shaping well-being-enhancing activities through interaction with everyday objects and technology. Our case study started from the activity of keeping ‘small’ secrets as a way to experience autonomy and privacy. We situated this activity in an office and ‘materialized’ it through a digital picture frame, holding a secret picture. Inspired by seven interviewees’ detailed descriptions of interacting with secrets, we designed an especially secretive interaction to consume the picture and compared it to a more technical interaction. In a first empirical exploration, using video prototypes (N = 276), the secretive interaction was rated as more positive and providing more intense feelings of privacy and autonomy. This hints at the potential of objects and the careful design of interaction with this objects to intensify the positive experiences gained from mundane activities.

Keymoment: initiating behavior change through friendly friction

Matthias Laschke; Sarah Diefenbach; Thies Schneider; Marc Hassenzahl

To initiate new behavior is challenging, but to maintain this new behavior can be even more so. In this paper, we present Keymoment, a key holder designed to increase physical activity by raising the frequency of taking the bike instead of the car. To accomplish this, it creates friction, but in a meaningful and light way. Keymoment is an example of what we call pleasurable troublemakers -- a genre of interactive things, designed to help people changing themselves. We discuss variations of the Keymoment as well as the general principles, pleasurable troublemakers are based on.

“Du lernst, dass du das nicht brauchst” — Ein transformationales Produkt zur Steigerung der Selbstkontrolle

Flavius Kehr; Matthias Laschke; Marc Hassenzahl

Zusammenfassung Wir stellen ein transformationales Produkt vor, das verführerische Situationen schafft, zu deren Bewältigung Selbstkontrolle erforderlich ist. Im Rahmen einer Pilotstudie wird untersucht, welche Erfahrungen Personen bei der 14-tägigen Nutzung des Produkts machen. Es zeigt sich, dass die Nutzung des Produkts auf eine freudvolle Weise zu einer stärkeren Selbstreflexion, zur Entwicklung spezifischer Bewältigungsstrategien und zur Verminderung der benötigten Selbstkontrollstärke führt. Abstract We present a transformational product, which creates seducing situations and thus stimulates self-control behavior. A pilot study explores the experiences of people during a 14-day product use. Usage led to increased self-reflection, the development of particular coping strategies and a decrease in regulatory strength — all in an enjoyable way.

Technology for Behavior Change – Potential, Challenges, and Ethical Questions

Sarah Diefenbach; Andreas Kapsner; Matthias Laschke; Jasmin Niess; Daniel Ullrich

The multitude of technologies in our daily life – smartphones, ticket machines, and communication services like WhatsApp or social media platforms like Facebook – naturally shapes our actions and thinking. Beyond this, technology also becomes a medium for actively influencing and changing human behavior. Often, the intended change in behavior aims at socially desirable goals, such as conscious, sustainable consumption, public safety, or the adoption of healthier lifestyles. Examples are speed monitoring displays, smart meters to control energy consumption, or mobile apps that remind their users of doing more sports. Also healthcare providers make use of such solutions and started to equip their customers with “smart technology”, tracking their actions and daily routines. A healthy lifestyle is rewarded with a fee reduction, or, in other words, not using such technology is punished with paying more. Apparently, such products have high potential to better our lives, but they also raise serious ethical concerns: Should we consider the induced changes in behavior as manipulation? And if so, in which cases might such manipulation be justified? Does the design of these products show enough respect for the autonomy, dignity and privacy of the users? The discussion of such normative issues has not yet reached any definitive conclusions. In general, we are a dealing with a relatively young product category that obviously asks for new models, metrics and quality criteria. While users and designers are confronted with such technologies in their daily life and working environment, many established criteria of “positive user experience” (e. g., efficiency, comfort) are not applicable anymore. Instead of making life easy and smooth, technologies for behavior change often deliberately create friction. The idea of an aesthetic of friction [3] is to break up routines to inspire reflection. For example, Keymoment [4] makes the choice between taking the car or the bike more deliberate. If the user takes the car key, Keymoment throws the bike key at the users’ feet. You can pick it up, hang it back and still take the car – or reflect on what might be good for your health and the environment. However, aesthetic of friction is only one possible design principle. It might not be suited for all contexts of behavior change and especially long term effects still require further exploration. Our goal is to develop, ideally in an interdisciplinary effort, more general standards, design guidelines and quality criteria that help us to describe, design and evaluate such products, also considering ethical perspectives. As a start to this endeavor, the present article points out some central questions about the potential, current challenges and ethical issues in the field of technology for behavior change. The following sections are based on a discussion between experts with backgrounds in psychology, design, media informatics and philosophy. Sarah Diefenbach, whose background is in psychology, led the discussion. Her current research centers around technology design as a chance to support self-improvement and well-being but also the critical side effects and ‘unhealthy routines’ initiated through technology and social media. Andreas Kapsner is a philosopher whose main focus has been the question in how far governments should make use of such technologies and techniques. The idea that this potential to lead citizens towards “health, wealth and happiness” should be vigorously exploited has been popularized by Richard Thaler and Cass Sunstein in their best-selling book “Nudge”.

Alles in Ordnung

Tobias Ellinger; Philip Oettershagen; Matthias Laschke; Marc Hassenzahl

Zusammenfassung Aufräumen ist nicht nur eine lästige Bürde. Die eigene Ordnung vermittelt uns auch das Gefühl von Sicherheit. Die vorliegende Arbeit stellt ein persuasives Konzept vor, das zu einem freudvollen Aufräumen am Schreibtisch motiviert. Konzept, Interaktion als auch die spätere formale Gestaltung adressieren das Erleben von Sicherheit und Autonomie. Abstract To tidy up is not just a burden. A personal order conveys the feeling of security. This paper presents a persuasive concept, which motivates tidying up the desk in an enjoyable way. Concept, interaction and the formal design all address the experience of security and autonomy.

Zwischen Können und Tun liegt ein großes Meer und auf seinem Grunde die gescheiterte Willenskraft

Marc Hassenzahl; Wolfgang Prinz; Hagen Buchholz; Matthias Laschke

Was wollen wir nicht alles tun! Weniger Fleisch essen (auch wegen der Tiere), weniger mit dem Auto fahren (auch wegen der Umwelt), weniger Arbeiten (auch für die Familie), mehr Lesen (besonders Fachliteratur), häufiger ins Konzert gehen (auch mal etwas Anspruchsvolleres) und häufiger Freunde treffen (besonders die, die wir schon lange nicht mehr gesehen haben) . Stattdessen frönen wir der Leberkässemmel (35 Gramm Fett), fahren schwere Autos (meist deutlich mehr als 130 Gramm CO2), arbeiten zu viel (immer diese Überstunden), lesen Krimis, schauen Fern und sind meist zu müde für Freunde (wegen der Arbeit und dem fetten Essen) . All diese Situationen haben eine ähnliche Struktur: es gibt etwas, das wir langfristig für uns persönlich oder für die momentane und zukünftige Gesellschaft für gut und richtig halten, und etwas, das in der momentanen Situation leichter erreichbar ist oder sogar mehr Freude macht (denn wer würde ernsthaft anzweifeln, dass eine Leberkässemmel lecker ist) . Es entsteht ein Konflikt zwischen zwei Handlungsalternativen, bei dem häufig die freudvollere Alternative gewinnt – auf Kosten der Umwelt, unserer Gesundheit oder unseres Wohlbefindens . Dementsprechend ist Willenskraft und Selbstkontrolle seit der Antike und bis heute ein wichtiges philosophisches und psychologisches Thema (siehe Hofmann et al ., 2011, für einen lesenswerten Überblick) . Denn durch das Verstehen von Willenskraft und seinen Bedingungen erhofft man sich eben auch, Wege zu finden, das Gute und Richtige etwas häufiger zu tun – Marie von EbnerEschenbachs „großes Meer“ etwas kleiner werden zu lassen . Mindestens seit B .J . Foggs (2003) Persuasive Technology werden auch interaktive Produkte als eine Möglichkeit verstanden, Einstellungen und Verhaltensweisen zu ändern . Dies ist nicht überraschend, denn Dinge haben die einzigartige Fähigkeit unser Verhalten auf recht subtile Weise zu formen . Das ist eine Fähigkeit, die der typischen Strategie fehlt . Diese setzt auf „aufklärende“ Kommunikation in Form von Informationsbroschüren zu gesunder Ernährung, Sport und Fitness, oder dem schonenden Umgang mit natürlichen Ressourcen . Klar scheint mittlerweile, dass diese bloße Informationsvermittlung wenig erfolgversprechend ist (z . B . Stadler et al ., 2006), was landläufig zu der Meinung führt, dass Verhalten nur schwer zu verändern ist . Die Macht der Gewohnheit ist sicher nicht immer leicht zu brechen; wenn aber, dann haben interaktive Produkte eine größere Chance auf Erfolg als bloße Kommunikation, weil sie unmittelbar Rückmeldung über eigene Handlungen und deren Konsequenzen geben und alternative Handlungsweisen nahelegen . Das ist häufig subtil . Ein Beispiel ist Matthias Laschkes und Kollegen (2011) Vergissmeinnicht, eine Leuchte in Form eines Blumenkelches, dessen Blätter sich über die Zeit von 20 Minuten schließen und dabei das Licht dimmen (siehe Bild 1) . Das Berühren eines Blattes öffnet die Lampe wieder .
