Im Jahr 2021 sind Self-Tracking-Technologien ein fester Bestandteil gesellschaftlicher Alltagspraxen. In der Gegenwart von Corona-Tracing-Apps und Social Scoring erinnert kaum noch etwas an die frühen Prototypen der technologieenthusiastischen Self-Tracker*innen. Thorben Mämecke wirft einen Blick auf die intensiven Beziehungen, die diese Pionierprojekte untereinander gepflegt haben, und zeichnet dabei die sie bestimmenden Phänomene nach: angefangen bei der Ellenbogenmentalität der prekären Kreativökonomie bis zum progressiven Selbstbestimmtheitsstreben von Self-Tracker*innen mit chronischen Erkrankungen.

Over the past few decades, modern information technology has made a significant impact on people’s daily lives worldwide. In the field of health care and prevention, there has been a progressing penetration of assistive health services such as personal health records, supporting apps for chronic diseases, or preventive cardiological monitoring. In 2020, the range of personal health services appeared to be almost unmanageable, accompanied by a multitude of different data formats and technical interfaces. The exchange of health-related data between different healthcare providers or platforms may therefore be difficult or even impossible. In addition, health professionals are increasingly confronted with medical data that were not acquired by themselves, but by an algorithmic “black box”. Even further, externally recorded data tend to be incompatible with the data models of classical healthcare information systems.From the individual’s perspective, digital services allow for the monitoring of their own health status. However, such services can also overwhelm their users, especially elderly people, with too many features or barely comprehensible information. It therefore seems highly relevant to examine whether such “always at hand” services exceed the digital literacy levels of average citizens.In this context, this reprint presents innovative, health-related applications or services emphasizing the role of user-centered information technology, with a special focus on one of the aforementioned aspects.

Selfies, blogs and lifelogging devices have become important ways in which we understand ourselves. Jill Walker Rettberg analyses these and related genres as three intertwined modes of self-representation: visual, written and quantitative. Rettberg explores topics like the meaning of Instagram filters, smartphone apps that write your diary for you, and the ways in which governments and commercial entities create their own representations of us from the digital traces we leave behind as we go through our lives.

Zahlen und Statistiken sind omnipräsent. Sie prägen die Berichterstattung über soziale, politische und wirtschaftliche Vorgänge und beeinflussen das alltägliche Denken über Gesellschaften und das soziale Zusammenleben. Ihnen kommt dabei häufig ein fast selbstverständlicher faktischer Status zu, eine Objektivität, welche sie gegenüber anderen Aussagen und Zugängen als quasi natürlich überlegen erscheinen lässt. Andreas Schaudauer nimmt sich diesem besonderen Status an und hinterfragt seine Entstehung und Legitimation. Darauf aufbauend geht er der Frage nach, inwiefern sich dieser Status aufrechterhalten lässt bzw. wie er sich verändert, wenn sein Entstehen offengelegt ist.
