Scientific publication of RECALL research results

RECALL Projects at PerDis’16

The Fifth ACM International Symposium on Pervasive Displays took place from 20th to 22nd of June 2016 in Oulu, Finland. The event brought together researchers from various disciplines with a common interest on the opportunities and challenges raised by the emergence of pervasive display systems. Investigating how pervasive displays can be used to provide memory cues has been one of the research focuses for RECALL from the beginning. Hence, our team — just like the year before —  had a significant presence with a full paper and 2 poster presentations.

Effects of Camera Position and Media Type on Lifelogging Images (MUM Best Paper Award)

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.

Reading Studies: Increasing Reading Speed and Comprehension

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

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.

Lifelogging and Challenges of a Holistic Quantified Self

Thanks to the ubiquity of smartphones and the availability of wearable technologies, large-scale data collection is on the rise. People log their steps with commercial products such as Fitbit and keep track of their activities and locations using apps like endomondo. Gordon Bell [1] went even further and made it his mission to attempt to record his entire life: images, sounds, videos as well as personal documents. He pioneered the trend towards lifelogging applications that has been supported by research projects such as Microsoft’s SenseCam [2]. Whereas technologies such as Fitbit are aimed at collecting quantitative data about movement and health to set incentives for improvement, the SenseCam serves as memory aid by automatically capturing a digital record of the wearer’s day.
