Effective Feedback Mechanisms for User Control in Personalization

Strategic Insights -

Users' online behavior is tracked to create unique profiles about their individual behavior and interests, raising concerns about data collection and users' privacy. Research conducted by the University of the Arts suggests that users do not understand the effects of tracking technology and feel helpless in controlling their profiles, despite having controls provided to them. A study proposes the use of effective feedback mechanisms to enable users to make informed decisions about tracking and personalization.

Key Takeaways:

  • The General Data Protection Regulation (GDPR) and the ePrivacy Directive regulate the collection and processing of personal data, but users often lack understanding and control over their online experience.
  • Users' expectations of privacy and the benefits and risks of personalization were explored through 20 qualitative interviews, revealing an immediate need for feedback mechanisms.
  • A prototyped on/off switch was used to enable users to compare personalized and non-personalized content, with preliminary evaluation suggesting its potential as an effective solution for user control.
  • The research concluded that an on/off toggle could represent the state of the art in enabling users to control tracking and personalization, considering the data protection by design requirement in Article 25, Section 1 of the GDPR.
  • The study's findings suggest that feedback mechanisms that are situated and timely are essential for effective user control.
  • Max von Grafenstein, Patrick Smieskol, and Timo Jakobi were the researchers involved in this study.

Statistics:

  • 20 qualitative interviews were conducted to explore users' privacy expectations and control needs.
  • 2 phases were conducted in the research: 1) 20 qualitative interviews, and 2) prototyping and evaluation of the on/off switch.
  • 1 on/off switch was prototyped and evaluated as a potential solution for effective user control.
  • 1 preliminary evaluation was conducted, confirming the potential of the on/off switch.
  • The study focused on full control, comparing personalized and non-personalized content through the on/off switch.
