At this year’s International Conference on Mobile and Ubiquitous Multimedia (MUM) we presented results from a RECALL study on lifelog camera positioning. MUM is a leading annual international conference, which provides a forum for presenting the latest research results on mobile and ubiquitous multimedia. The paper – spearheaded by Katrin Wolf – has been awarded with the best paper award.
In the paper we report on an evaluation of existing visual lifelogging capture approaches. Continue reading Effects of Camera Position and Media Type on Lifelogging Images (MUM Best Paper Award)
In our previous work [1, 2, 3], we compared first-person-view lifelog images – e.g., images taken using Narrative Clip devices – with third-person-view lifelog images – e.g., images captured by fixed infrastructure cameras. First-person view images usually provide a very particular vantage point, and as such may miss many things: camera lenses may get covered by clothes or hair, or may simply face the wrong way due to the way they are “mounted” on the body (e.g., with a clip). Even if an unobstructed view can be had, a first-person-view may only show a very small part of the scene, e.g., potentially never showing a person that sits right next to us. Images from fixed infrastructure cameras can compensate for such shortage: their high vantage point usually allows them to captures comprehensive scenes, completely unobstructed. Alternatively, a first-person-view image from another person may equally offer an interesting alternative to my own capture. These considerations prompted us to investigate the best way to combine first-person-view and third-person-view images in RECALL to reconstruct a better representation of a previous experience.

Researchers from the Recall project recently discussed their work and participated in the European Commission’s ICT 2015 event. The event, held in Lisbon from 20-22nd October 2015 with the theme ‘Innovate, Connect, Transform’ provided a unique opportunity to highlight the exciting vision of Recall, prompt new discussion around the topic of memory augmentation, and to help promote scientific exploration of augmented cognition in Europe.
As part of their participation in the event, the Recall project members hosted a 45-minute networking session on the topic of `Augmenting Human Cognition – ICT to support capture, reflection and recall’. The vision statement for this session — The time is ripe to attempt the creation of memory augmentation technology that provides the user with the experience of an extended and enhanced memory, but which is based on improvements in the collection, mining, and presentation of appropriate information to facilitate cued memory recall — attracted significant interest from attendees and the session was very well attended.
With approximately 50 attendees from 16 different countries, the event was a fantastic platform for exchanging ideas for advancing ICT and human cognition. The event built new connections between European researchers, innovators and decision makers interested in exploring the area of augmented human cognition. During the session participants worked together to develop the community’s understanding of the challenges, approaches, and possibilities in the space, as well as a shared awareness of work in this area across Europe. Participants generated a wealth of ideas for future research directions in the field and the level of discussion was intense. The feedback on the event was overwhelmingly positive with everyone agreeing that they had successfully networked with new people. We have made a comprehensive report on the event available for download: ICT 2015 Networking Event Report.
On August, 24th, at this year’s MobileHCI conference in Copenhagen, members of the RECALL team organized and hosted the workshop on “Mobile Cognition – Using Mobile Devices to Enhance Human Cognition”. We gathered 11 attendees and 7 accepted position papers involving topics like using lifelogging to foster behavior change in a mobile environment as well as cognitive challenges during navigation tasks, just to name a few.

An article published in BBC future features work of Recall researcher Evangelos Niforatos as one of a group of scientific investigations centred on how photo taking influences human memory.

On June 24-28 Recall researcher Dr Caterina Cinel attended SARMAC 2015, a biennial conference on applied memory and cognition. Researchers at the conference present work where psychological theories of memory and cognition are applied to real-word domains, such as law, education, advertising, politics, etc. At the conference, Caterina presented a poster showing the research carried out at Essex University in the last year on retrieval-induced forgetting (RIF). RIF is a well-studied phenomenon where retrieval practice of a subset of events can enhance their later recall, but can impair accessibility to related but unreviewed events. In seven experiments, Essex researchers C. Cinel and G. Ward show that we can manipulate factors that selectively amplify and/or attenuate the forgetting and enhancement of selected memories. However, whereas retrieval practice effects can be found with all stimuli, to date, evidence for RIF has been limited to semantic lab-based stimuli, while we found limited evidence of RIF with real-word, episodic stimuli.
The poster was very well received and during the presentation session many researchers have shown interest in our research and given valuable insight and comments.
Our RECALL-hosted Workshop on Mobile Cognition at MobileHCI 2015 is shaping up. After our submission deadline in mid-June, we distributed the received manuscripts to a select set of reviewers and then proceeded to make a final selection. Here’s a small preview of the six papers to be presented at the workshop.

Last week researchers from RECALL presented a series of papers, a tutorial and demonstration at the PerDis 2015 symposium in Saarbrucken, Germany.
The presence of ubiquitous displays (both in the environment and via personal devices such as smartwatches and Google Glass) provides many new opportunities for displaying memory cues to trigger recall. The PerDis symposium is focused on communication through and use of pervasive display systems in public and semi-public spaces and such displays have huge potential for helping to deliver memory cues in the future. However, presenting memory cues on public displays poses new challenges, and as part of our research into memory visualisation we are exploring these. For example, development of new scheduling architectures and personalisation models for memory augmentation through public displays.
At the PerDis symposium, our researchers presented their work in the domain of public displays and engaged in many interesting conversations with others who were excited about memory augmentation as a new application domain for digital signage and pervasive displays. We were really pleased to get such positive feedback and hope that this topic will continue to excite the community.
In RECALL we aim to augment human memory in several ways; one of which being the strand of semantic memory. Therefore, we started looking into the design of knowledge acquisition points and – due to its prominence in learning and information consumption – reading.
With the advent of the information age and the creation of electronic reading devices – such as mobile phones, e-readers or tablets – our reading behavior has been changing and we are facing new challenges, one of which being information overload. We are bombarded with an abundance of text on a daily basis: news, emails, tweets, feeds, books, papers, articles, technical literature and pleasure readings. But our reading strategy has mainly remained the same. Continue reading Reading Studies: Increasing Reading Speed and Comprehension
Two presentations from the Essex researchers working on RECALL have been accepted at key international memory conferences.
Geoff Ward will be presenting this May at CEMS 2015 (Context and Episodic Memory Symposium) in Philadelphia some of the retrieval-induced forgetting (RIF) work from the RECALL grant. This conference is heavily theoretically driven, but includes work by Prof. Simon Dennis (University of Newcastle) who is presenting on experience-sampling in the wild, a line of research similar to the experience sampling (XPR) work that we are planning.
Caterina Cinel will give a presentation in June at SARMAC XI (Society for Applied Research in Memory and Cognition), in Victoria, BC, again about Retrieval Induced Forgetting in the real world. This conference is far more applied in outlook, and we are keen to see how our research is considered by those interested in such fields as eye-witness testimony, memory training, and the role of memory testing in education.
