Exploring Intuitive Lifelog Retrieval and Interaction Modes in Virtual Reality with vitrivr-VR

The multimodal nature of lifelog data collections poses unique challenges for multimedia management and retrieval systems. The Lifelog Search Challenge (LSC) offers an annual evaluation platform for such interactive retrieval systems. They compete against one another in finding items of interest within a set time frame. In this paper, we present the multimedia retrieval system vitrivr-vr, the latest addition to the vitrivr stack, which participated in the LSC in recent years. vitrivr-vr leverages the 3D space in virtual reality (VR) to offer novel retrieval and user interaction models, which we describe with a special focus on design decisions taken for the participation in the LSC

Geospatial access to lifelogging photos in virtual reality

We present a virtual reality system for accessing geotagged photos taken with a lifelogging camera. Photos are spatially located on a world map that can be explored with a head-mounted display. Using a virtual reality headset allows users to easily and intuitively explore this large information space. Images are initially represented by icons but become visible once a user gets closer to a particular area of interest. While not suitable for all search tasks, this visualisation has benefits in situations where location plays a significant role; be it because the actual content is location-related or because the owner of the lifelog remembers and associates the related event with certain places. Likewise, our spatial representation of the data often implicitly reveals a temporal relationship, which can be helpful in the search process as well

Durchbrochene Ordnungen: Das Dokumentarische der Gegenwart

Von der Entstehung technischer Analogmedien im 19. Jahrhundert bis in die Gegenwart digitaler Medienpraktiken hinein ist eine Vielzahl dokumentarischer Formen entstanden. Im Zentrum dieses Bandes steht die Frage nach den Operationen, die im Rahmen unterschiedlicher Institutionen und Praktiken auf je spezifische Weise bild-, text- und tonmediale Elemente arrangieren, um so die Lesbarkeit, den Aussagewert und die Machtwirkungen des Dokumentierten zu steuern. Verschiedene Leitkonzepte spielen dabei eine zentrale Rolle: Das Dokumentarische 2.0 in den diversen Praktiken ubiquitärer Selbstdokumentation, etwa in Social Media (Neodokumentarismus), sowie das Dokumentarische zweiter Ordnung, das sich in kritischer Weise auf die Objektivitäts- und Evidenzansprüche dokumentarischer Wahrheiten bezieht und sie "gegendokumentarisch" unterläuft
