Using life-logging devices and wearables is a growing trend in today’s society. These yield vast amounts of information, data that is not directly overseeable or graspable at a glance due to its size. Gathering a qualitative, comprehensible overview over this quantitative information is essential for life-logging services to serve its purpose. This thesis provides an overview comparison of CLARANS, DBSCAN and SLINK, representing different branches of clustering algorithm types, as tools for activity detection in geo-spatial data sets. These activities are then classified using a simple model with model parameters learned via Bayesian inference, as a demonstration of a different branch of clustering. Results are provided using Silhouettes as evaluation for geo-spatial clustering and a user study for the end classification. The results are promising as an outline for a framework of classification and activity detection, and shed lights on various pitfalls that might be encountered during implementation of such service.

The purpose of this thesis is to explore how a web-based image visualisation interface can be designed to complement an existing product. To achieve this purpose a study was conducted at Narrative, a small independent developer. Their newly released product, the Narrative-clip, is a small automatic camera that takes two pictures every minute. The camera is accompanied by cloud storage functionality and a mobile application which lets the users view their images. Due to the large amount of pictures taken by the camera, voices have been raised for a web-based system to be developed to increase the accessibility of the user content. The goal of the study was to identify requirements, develop a design suggestion for a web-interface and evaluate the interface from a stakeholder perspective. The study employed a hybrid design method, drawing on strengths from several recognised and popular design methods. Interviews were conducted with both users and employees at Narrative to identify demands and expectations of the system. The information gathered was later concretised in a design workshop with the goal of producing ideas and solutions to the system. The gathered material was used in three iterative steps, resulting in a final high-fidelity prototype. Each of the iterations used usability testing to identify design issues and to motivate improvements on the system. The conclusion is two-fold: three characteristics important for the final design and two key aspects for the design mindset. The characteristics found to be central for the web-interface were a simple design over multiple features, familiarity with the design and a good overview of one's uploaded content. Furthermore, the design process mindset was equally important. Identified aspects of the mindset that were important for the final design were a broad context and follow-up work.

While both public opinion and scholars around the world are currently pointing out the danger of increasingly popular life-logging devices, this book articulates this debate by distinguishing between automatic and manual life-logging approaches. Since new definitions of life-logging have excluded the latter approach and have been mainly focused on effortless life-logging technologies such as Google Glass and Quantified Self applications in general, the second part of this thesis theoretically frames life-stowing.Through extensive etymological research, I have defined life-stowing as a manual and effortful practice conducted by life-stowers, individuals who devote their life to sampling reality in predefined frameworks. As part of this book, an historical overview introduces life-stowers and distinguishes between Apollonian and Dionysian varieties of these practitioners. Lastly, in order to understand the future reception of life-stowing, particularly in relation to digital media, I have disclosed my ongoing life-stowing project to a small audience. / Den samtida samhälls- och forskningsdebatt, där de allt mer populära teknologierna för life-logging ofta framställs som farliga, vidgas och utvecklas i denna bok genom ett särskiljande av automatiska och manuella tekniker för life-loggning. Eftersom nya definitioner av life-loggning i stor utsträckning har exkluderat manuella tekniker och fokuserat på egenmätning som inte kräver så mycket av användaren, såsom GoogleGlass, innehåller avhandlingen också ett teoretisk utforskande av begreppet lifestowing. Genom omfattande etymologisk forskning definieras life-stowing i avhandlingen som en manuell och ansträngande praktik utförd av life-stowers, personer som vigt sina liv åt att samla och spara bitar av verkligenheten enligt fördefinierade ramar. I den historiska översikten introduceras två typer av life-stowers, den Apollonianska och den Dionysiska. Slutligen, för att förstå det framtida mottagandet av life-stowing i relation till digitala medier, presenteras författarens egna life stowingprojekt för en mindre publik.
