    Code, space and everyday life

    In this paper we examine the role of code (software) in the spatial formation of collective life. Taking the view that human life and coded technology are folded into one another, we theorise space as ontogenesis. Space, we posit, is constantly being bought into being through a process of transduction – the constant making anew of a domain in reiterative and transformative practices - as an incomplete solution to a relational problem. The relational problem we examine is the ongoing encounter between individuals and environment where the solution, to a greater or lesser extent, is code. Code, we posit, is diversely embedded in collectives as coded objects, coded infrastructure, coded processes and coded assemblages. These objects, infrastructure, processes and assemblages possess technicity, that is, unfolding or evolutive power to make things happen; the ability to mediate, supplement, augment, monitor, regulate, operate, facilitate, produce collective life. We contend that when the technicity of code is operationalised it transduces one of three forms of hybrid spatial formations: code/space, coded space and backgrounded coded space. These formations are contingent, relational, extensible and scaleless, often stretched out across networks of greater or shorter length. We demonstrate the coded transduction of space through three vignettes – each a day in the life of three people living in London, UK, tracing the technical mediation of their interactions, transactions and mobilities. We then discuss how code becomes the relational solution to five different classes of problems – domestic living, travelling, working, communicating, and consuming

    WHERE DO YOU BREATHE?

    The project wheredoyoubreathe.net consists of three elements: a photographic essay, an urban intervention, and a website. The photographic essay forms an investigation of the city through the act of walking. As opposed to the image of the city as a dense world and a conglomerate of vibrant urban spaces full of things, the photographic essay tries to portray it as a tranquilised terrain open to contemplation, a post-industrial and uprooted, yet surprisingly bucolic landscape where one can roam and linger. By walking the landscape, open yet personal spaces get revealed alongside the city’s designated living, working or sociable spaces. They function as possible chill-out spaces for the city walker, and could be called ‘breathing spaces’. The photographic essay is as much a search for this specific urban space as it is an evocation of London as a fluid landscape of possibility

    STATBOX Concept for Simulation of Urban Phenomena

    AbstractAn urban environment is a dynamic system which is constantly changing in terms of space and time. There are two dimensions in any urban environment – the physical dimension and the functional dimension. All of the structures of an urban environment interact and people are the intermediaries in this process. The spatial structure of cities has been studied from various perspectives by architects, urban planners, environmental scientists, economists, geographers etc. Constant monitoring that is based on remote sensing, spatial statistics, simulation etc., is needed to make on going note of transformation in the various types of land use that exist, movement of people and business environment. Many authors stressed that using the GIS technology, the spatial features of geographic data can be introduced in the simulation and GIS, spatial analysis plays an important role in the development of geosimulation models. The integration of the virtual reality technology with a dynamic data model will gives a realistic representation and visualization of the real world. Such complex accessibility for the user with an excellent interaction and manipulation capabilities of the virtual environment will be used in different kind of projects connected with simulating urban phenomena or pedestrian/crowd movements. The presented system consists of the STATBOX units, comprising of video data storage. Data collected by STATBOX units is sent to the Main server, where the video data is processed to generate classified information. Based on the collected statistical data, as well as information on the location of the STATBOX units and GIS models of territory, the geosimulation model is automatically prepared. The model is adequate to the real world - no deep knowledge on the simulation techniques is needed to use the proposed system. A prototype of Riga central park performance model is used as an example of STATBOX data collection and simulation process. GIS system with integrated ortofoto map, digital route map, digital plan of landuse, are used as the basis for the model development. The result is a geosimulation model adequate to the pedestrian movement and ready for further experiments. The created system can be used by different users, like businessmen/investors, researchers, state and municipal institutions. However, the main target group is the SMEs, as they are more flexible and ready to take decision to change location than large companies

    Walking as Do-It-Yourself Urbansim

    This article develops a series of theoretical notions arising in the context of an urban art project that took place in London in the summer of 2004 under the title “Where do you breathe?”1 As a participatory urban intervention, the project challenged the notion of authorship in public space by casting the act of walking as a transformation of urban space, and examined the potentials for a practice of photography based on interaction rather than passive representation

    MOSAIC vision and scenarios for mobile collaborative work related to health and wellbeing

    Get PDF
    The main objective of the MOSAIC project is to accelerate innovation in Mobile Worker Support Environments by shaping future research and innovation activities in Europe. The modus operandi of MOSAIC is to develop visions and illustrative scenarios for future collaborative workspaces involving mobile and location-aware working. Analysis of the scenarios is input to the process of road mapping with the purpose of developing strategies for R&D leading to deployment of innovative mobile work technologies and applications across different domains. This paper relates to one specific domain, that of Health and Wellbeing. The focus is therefore is on mobile working environments which enable mobile collaborative working related to the domain of healthcare and wellbeing services for citizens. This paper reports the work of MOSAIC T2.2 on the vision and scenarios for mobile collaborative work related to this domain. This work was also an input to the activity of developing the MOSAIC roadmap for future research and development targeted at realization of the future Health and Wellbeing vision. The MOSAIC validation process for the Health and Wellbeing scenarios is described and one scenario – the Major Incident Scenario - is presented in detail

    Integration of georegistered information on a virtual globe

    In collaborative augmented reality (AR) missions, much georegis-tered information is collected and sent to a command and control center. This paper describes the concept and prototypical imple-mentation of a mixed reality (MR) based system that integrates georegistered information from AR systems and other sources on a virtual globe. The application can be used for a command and control center to monitor the field operation where multiple AR users are engaging in a collaborative mission. Google Earth is used to demonstrate the system, which integrates georegistered icons, live video streams from field operators or surveillance cameras, 3D models, and satellite or aerial photos into one MR environment

    Automated Knowledge Generation with Persistent Surveillance Video

    The Air Force has increasingly invested in persistent surveillance platforms gathering a large amount of surveillance video. Ordinarily, intelligence analysts watch the video to determine if suspicious activities are occurring. This approach to video analysis can be a very time and manpower intensive process. Instead, this thesis proposes that by using tracks generated from persistent video, we can build a model to detect events for an intelligence analyst. The event that we chose to detect was a suspicious surveillance activity known as a casing event. To test our model we used Global Positioning System (GPS) tracks generated from vehicles driving in an urban area. The results show that over 400 vehicles can be monitored simultaneously in real-time and casing events are detected with high probability (43 of 43 events detected with only 4 false positives). Casing event detections are augmented by determining which buildings are being targeted. In addition, persistent surveillance video is used to construct a social network from vehicle tracks based on the interactions of those tracks. Social networks that are constructed give us further information about the suspicious actors flagged by the casing event detector by telling us who the suspicious actor has interacted with and what buildings they have visited. The end result is a process that automatically generates information from persistent surveillance video providing additional knowledge and understanding to intelligence analysts about terrorist activities
