Showcasing RECALL technology

Recall at PerDis 2015

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.

Déjà vu – Technologies that make new Situations look Familiar

In this post we want to discuss the application of a concept known as Déjà vu; making use of its effects we envision technologies that make new situations and encounters more familiar and less threatening.

Going to new places, interacting with new people and carrying out new tasks is part of everyday life. New situations create a sense of excitement but in many cases also anxiety based on a fear of the unknown.

In RECALL we started exploring the use of peripheral displays to automatically provide  information about potential future experiences in order to allow people to learn incidentally and without conscious effort about new environments and people. The expectation is that having visual information provided, we can create a sense of déjà vu when people are in a new situation. We use the term déjà vu it a positive sense, following the definition of the Oxford dictionary: “feeling of having already experienced the present situation”.

Atmos: Crowd–sourcing Estimations about Current and Future Weather Conditions

This month saw the International Joint Conference on Pervasive and Ubiquitous Computing (UbiComp) held in the unexpectedly sunny Seattle. UbiComp is the premier conference in the field, regularly attracting over 700 participants. RECALL had a strong presence there, with team members organizing a novel Workshop on “Ubiquitous Technologies for Augmenting the Human Mind (WAHM)”. In additional, RECALL team member Evangelos Niforatos presented his work on the Atmos system in the conference’s poster session .

Atmos allows collecting empirical reports about current weather conditions.

Atmos is a novel approach to weather estimation. It introduces the use of participatory sensing to collect in-situ weather data, both from sensors and human input. Atmos leverages a crowd-sourcing network of mobile devices to generate highly localized information about current and future weather conditions. Participatory sensing involves the utilization of mobile devices to form interactive, collaborative sensor networks that enable users to garner, analyze and share local knowledge. Under this guise, participatory sensing exhibits a unique level of spatio-temporal coverage in observing phenomena of interest in urban spaces. The key idea behind this new paradigm is the enabling of mobile users to collect and share sensed data about their natural settings in large scale, using their mobile devices.
