As HCI shifts “to the wild”, in-situ methods such as Diary Methods and the Experience Sampling Method are gaining momentum. However, researchers have acknowledged the intrusiveness and lack of realism in these methods and have proposed solutions, notably through lightweight and rich media capture. In this paper we explore the concept of lifelogging as an alternative solution to these two challenges. We describe Footprint Tracker, a tool that allows the review of lifelogs with the aim to support recall and reflection over daily activities and experiences. In a field trial, we study how four different types of cues, namely visual, location, temporal and social context, trigger memories of recent events and associated emotions. We conclude with a number of implications for the design of
lifelogging systems that support recall and reflection upon recent events as well as ones lying further in our past.
Ruben Gouveia did just great. He was a awarded a national PhD scholarship to work on lifelogging tools for patients of episodic memory impairment over the next three years. Congrats Ruben!
Human memory is a powerful tool, allowing us to remember past incidents, such as where we left our keys, or where we parked our car. It can also lead us to forget things that we have to do, or specific details of past events. This is emphasized in people that suffer from clinically diagnosed memory disorders such as Alzheimer disease, which impair episodic memories, drawing them away from their natural ability of recalling past experiences. Lifelogging systems have proven to support memory recollection of significant experiences, leading EMI patients to regain a sense of normality in their lives. With this project, we intend to extend existing knowledge through studying how Footprint Tracker, a life logging system that captures visual, location and social context logs can impact the life of patients suffering from episodic memory impairment.
About a year ago I was invited to submit my PhD work to Springer. The book is finally out, it contains an iterated version of the work I did during my PhD studies along with two great contributions from my advisor, Jean-Bernard Martens (foreword), and my colleague and mentor, Marc Hassenzahl (closing note).
It took almost three years since the original submission in Arxiv, but it was worth it. In my humble opinion, the work from my PhD project that makes me most proud. Let’s see if I just took the wrong path. None would be possible without Jean-Bernard and Marc, but also without the professionalism of the editor, Kasper Hornbaek, and the reviewers.
Abstract: We present iScale, a survey tool for the retrospective elicitation of longitudinal user experience data. iScale aims to minimize retrospection bias and employs graphing to impose a process during the reconstruction of one’s experiences. Two versions, the constructive and the value-account iScale, were motivated by two distinct theories on how people reconstruct emotional experiences from memory. These two versions were tested in two separate studies. Study 1 aimed at providing qualitative insight into the use of iScale and compared its performance to that of free-hand graphing. Study 2 compared the two versions of iScale to free recall, a control condition that does not impose structure on the reconstruction process. Overall, iScale resulted in an increase in the amount, the richness, and the test–retest consistency of recalled information as compared to free recall. These results provide support for the viability of retrospective techniques as a cost-effective alternative to longitudinal studies.

With the increasing sophistication of mobile computing, a growing interest has been paid to locative media that aim at providing immersive experiences. Location aware narratives are a particular kind of locative media that aim at ‘‘telling stories that unfold in real space’’. This paper presents a study that aimed at assessing an underlying hypothesis of location-aware narratives: that the coupling between the physical space and the narrative will result in increased levels of immersion in the narrative. Forty-five individuals experienced a location-aware video narrative in three locations: (a) the original location that contains physical cues from the narrative world, (b) a different location that yet portrays a similar atmosphere, and (c) a location that contains neither physical cues nor a similar atmosphere. Sig- nificant differences were found in users’ experiences with the narrative in terms of immersion in the story and mental imagery, but not with regard to feelings of presence, emotional involvement or the memorability of story elements. We reflect on these findings and the implications for the design of location-aware narratives and highlight questions for further research.

Users’ experiences are increasingly becoming central to design activity. Designers and engineers strive for experiential design goals such as enhancing feelings of connectedness across family members, and consequently use experiential metrics in the evaluation of products and services. But can we measure experience in a valid and reliable manner? Research in Psychology suggests that experiences can only be measured at the time of their occurrence. Once they have ended, experiential information does not exist; it can only be reconstructed from contextual cues found in episodic memory. In this talk I will highlight the relation between memory and experience and its implications for the evaluation of products and services, in particular mobile and pervasive ones. I will describe techniques aimed for measuring experiences in a valid and reliable way such as the Experience Sampling Method (ESM) and the Day Reconstruction Method (DRM). I will take the view that memories of experiences are sometimes more interesting and relevant that the actual experiences, and I will illustrate a new methodological approach I call technology assisted reconstruction as explicated through my PhD work on the measurement of user experience over time and iScale, a tool that uses sketching to assist users in reconstructing their experiences with a product and thus uses human memory as a source of longitudinal HCI data, as well as more recent work on using visual and location data to support reconstruction processes.

Barreto, M., Karapanos, E., Nunes, N. Social Translucence as a theoretical framework for sustainable HCI. In proceedings of INTERACT 2011.
Motivating sustainable behaviors is increasingly becoming an important topic in the HCI community. While a substantial body of work has focused on the role of peer-pressure through social networks, we argue that the community has largely overlooked the importance of strong social ties and specifically those of family members.

My PhD thesis was nominated for the TU/e Doctoral award 2011. The award was won by Wiebe Wagemans (fascinating work on the magnetic properties of organic materials), but it was a nice excuse for a short trip to Eindhoven. Here is the proof that the trip wasn’t all about beer drinking. Ah, not to forget, you can also have a look on my thesis below.
I recently came back from Tampere and the wonderfully organized Long Term User Experience seminar. I keep being amazed with the dynamics of the HCI community of a country of just above 5 million people. Interesting people, interesting discussions. I tried to motivate the importance of Long-term UX and talked about our work on iScale (both presentations below). I further joined the DELUX project meeting. I was positively surprised from the close collaboration with industrial partners, and the diversity and emphasis on quality that these companies have. Warm thanks to Sari Kujala and the DELUX team for inviting me to this great event.
iScale is a survey tool for the retrospective elicitation of longitudinal user experience data. iScale employs sketching in imposing a process in the reconstruction of one’s experiences with the aim to minimize retrospection bias. Two versions, the Constructive and the Value-Account iScale, were motivated by two distinct theories on how people reconstruct emotional experiences from memory. The constructive iScale tool imposes a chronological order in the reconstruction of one’s experiences. It assumes that chronological reconstruction results in recalling more contextual details surrounding the experienced events and that the felt emotion is constructed on the basis of the recalled contextual details. The Value-Account iScale tool explicitly distinguishes the elicitation of the two kinds of information: value-charged (e.g. emotional) and contextual details. It assumes that value-charged information can be recalled without recalling concrete contextual details of an experienced event due to the existence of a specific memory structure that stores the frequency and intensity of one’s responses to stimuli.
In recent experiments it was shown that iScale results in an increase in the amount, the richness, and the test-retest reliability of recalled information. These results provide support for the viability of retrospective techniques as a cost effective alternative to longitudinal studies.

Evaluation should be integral to any design activity. Evaluation in innovative product development practices however is highly complicated. It often needs to be applied to immature prototypes, while at the same time users’ responses may greatly vary across different individuals and situations. This creates highly complex data which traditional statistical practices often fail to analyze. This section describes a number of tools for the elicitation and analysis of rich subjective data about product experience. Read more »
