Can Privacy-Aware Lifelogs Alter Our Memories?

The abundance of automatically-triggered lifelogging cameras is a privacy threat to bystanders. Countering this by deleting photos limits relevant memory cues and the informative content of lifelogs. An alternative is to obfuscate bystanders, but it is not clear how this impacts the lifelogger's recall of memories. We report on a study in which we compare viewing 1) unaltered photos, 2) photos with blurred people, and 3) a subset of the photos after deleting private ones, on memory recall. Findings show that obfuscated content helps users recall a lot of content, but it also results in recalling less accurate details, which can sometimes mislead the user. Our work informs the design of privacy-aware lifelogging systems that maximizes recall and steers discussion about ubiquitous technologies that could alter human memories

Prisoner of Words: Lessons learnt from mobile gamification of lab memory experiments

Gamifying experiments in-the-wild showed promising opportunities in supporting participants\u27 engagement, increasing sample size and diversity, and saving lab and personnel resources needed for lab experiments. However, transforming memory lab experiments to mobile games is challenging as some standard game design guidelines jeopardize the validity of the experimental design. Our work draws attention to this trade-off by providing design guidelines for critical game elements, namely scoring systems and input methods. We distil those guidelines from a case study where we replicated a lab memory experiment via a mobile game apparatus and produced congruent psychological results. Our work sheds the light on the special challenges in gamifying memory experiments and encourages psychologists and game designers to investigate human memory in natural settings

I (Don\u27t) Know What You Did Last Summer: A Framework for Ubiquitous Research Preservation

Research preservation is a pillar for knowledge transfer, science reproducibility and saving time by reusing existing resources. However, human compliance with efficient capturing strategies is a key barrier to creating complete scientific repositories. To circumvent this issue, we introduce the term: Ubiquitous Research Preservation (URP), describing automated knowledge capturing and retrieval in computational science. We also propose a framework composed of three models for designing URP systems (URPS) to 1) understand users\u27 interaction and data governance, 2) propose technical pipelines for data management, and 3) understand users\u27 sharing practices. Our work is a theoretical reflection on our past experiences in designing URPS. We plan future evaluation by using the framework to analyze existing URPS. We expect a positive impact from using URPS on researchers\u27 sense-making and ability to share findings and resources. Our framework is a checklist for design decisions needed to build successful URPS

\u27I Don\u27t Need a Goal\u27: Attitudes and Practices in Fitness Tracking beyond WEIRD User Groups

Fitness trackers have the potential for fostering sustained change and increasing well-being. However, the research community is yet to understand what design features and values need to be embodied in a fitness tracker for long-term engagement. While past work mainly focused on WEIRD (Western, Educated, Industrialised, Rich, Democratic) fitness trackers usersin North America and Western Europe, this paper investigates another perspective on fitness tracking. We conducted interviews with N = 37 fitness tracker users in the US, Europe and Egypt to identify the similarities and differences in attitudes and practices in fitness tracking. We found that fitness tracking involved a deeper social context in Egyptian communities and our findings suggest that Arabic users focused on physiological measurement, while non-Arab Western users appear to bewere more interested in goal achievement. We contribute design dimensions that can help build more inclusive tracker experiences. Our work highlights how future fitness trackers should support a customisable spectrum of design values to offer engaging experiences to a diverse and global audience
