Abstract In this article I will elucidate the concept of photo messaging, and examine camera phones in the context of communication and photography. Camera functions are nowadays a popular add-on to the mobile (cellular) phone. Users can send photographs directly from the phone as photo messages. Findings suggest that the ubiquitous camera phone, and photo messaging, may substantially change the ways in which people use personal photography. The imaging capacity of mobile phones is becoming a potential part of perpetual visual contact. Thus taking and sending photographs on a camera phone represents a new resource for visual communication.

Using social media platforms to document excessive police force at times of social unrest has become common practice among protestors around the world, from Cairo, Egypt to Ferguson, USA. Smart phones and social media have become indispensable tools to demonstrators as they organize, communicate, express dissent, and document any police brutality aimed at them. This chapter discusses the function of mobile communication technology as tool of sousveillance through an analysis of camera phones and the user-generated images in the mid-to-late 2000s. It argues that camera phones facilitated lateral surveillance and sousveillance practices, enabling ordinary individuals to watch social peers or those in power positions, albeit in non-systematic, non-continuous and spontaneous ways.

The World

Mobile communication is a key enabler for economic, social, and political change in developing regions of the world. This paper describes IBM Picture Discussions, which is a mobile social computing application framework designed to facilitate local information sharing in regions with sparse Internet connectivity, low literacy rates, and having users with little prior experience with information technology. IBM Picture Discussions runs on today’s internet-enabled smartphones as well as camera phones with multimedia messaging. In this paper, the authors argue that engaging citizens in developing regions in information creation and information sharing leverages peoples’ existing social networks to facilitate transmission of critical information, exchange of ideas, and distributed problem solving. All of these activities can support economic development.

Market Diffusion

This chapter is an empirical research report describing the diffusion of mobile camera phones and picture mail services in Japan between the years 1997 and 2005, based on annual consumer surveys conducted by Ericsson Consumer & Enterprise Lab. A general framework based on sociocultural values and attitudes to telecom for describing the telecom market from a consumer perspective is presented. This framework is then used to put different consumer life stage segments in relation to each other in respect to product diffusion. The change over time of attitudes and behavior is described, and the conclusion is drawn that the product terminology spontaneously created by consumers themselves in order to relate to the product is an important step for mass market diffusion. Furthermore, the group of people who develop this terminology becomes a crucial catalyst for diffusion—and in the Japanese case presented here consists of female students.

Photo Management

This chapter explores some of the technological elements that will greatly enhance user interaction with personal photos on mobile devices in the near future. It reviews major technological innovations that have taken place in recent years which are contributing to re-shaping people’s personal photo management behavior and thus their needs, and presents an overview of the major design issues in supporting these for mobile access. It then introduces the currently very active research area of content-based image analysis and context-awareness. These technologies are becoming an important factor in improving mobile interaction by assisting automatic annotation and organization of photos, thus reducing the chore of manual input on mobile devices. Considering the pace of the rapid increases in the number of digital photos stored on our digital cameras, camera phones and online photoware sites, the authors believe that the subsequent benefits from this line of research will become a crucial factor in helping to design efficient and satisfying mobile interfaces for personal photo management systems.

Mobile Context

Video management research has been neglecting the increased attractiveness of using cameraequipped mobile phones for the production of short home video clips. But specific capabilities of modern phones — especially the availability of rich context data — open up new approaches to traditional video management problems, such as the notorious lack of annotated metadata for home video content. In this chapter, we present MobiCon, a mobile, context-aware home video production tool. MobiCon allows users to capture video clips with their camera phones, to semi-automatically create MPEG-7-conformant annotations by exploiting available context data at capture time, to upload both clips and annotations to the users’ video collections, and to share these clips with friends using OMA DRM. Thereby, MobiCon enables mobile users to effortlessly create richly annotated home video clips with their camera phones, paving the way to a more effective organization of their home video collections.

scholarly journals When Citizens Are “Actually Doing Police Work”: The Blurring of Boundaries in WhatsApp Neighbourhood Crime Prevention Groups in The Netherlands

Ethnic Profiling

Neighbourhood watch messaging groups are part of an already pervasive phenomenon in The Netherlands, despite having only recently emerged. In many neighbourhoods, street signs have been installed to make passers-by aware of active neighbourhood surveillance. In messaging groups (using WhatsApp or similar communication apps), neighbours exchange warnings, concerns, and information about incidents, emergencies, and (allegedly) suspicious situations. These exchanges often lead to neighbours actively protecting and monitoring their streets, sending messages about suspicious activities, and using camera-phones to record events. While citizen-initiated participatory policing practices in the neighbourhood can increase (experiences of) safety and social cohesion, they often default to lateral surveillance, ethnic profiling, risky vigilantism, and distrust towards neighbours and strangers. Whereas the use of messaging apps is central, WhatsApp neighbourhood crime prevention (WNCP) groups are heterogeneous: they vary from independent self-organised policing networks to neighbours working with and alongside community police. As suggested by one of our interviewees, this can lead to citizens “actually doing police work,” which complicates relationships between police and citizens. This paper draws on interviews and focus groups in order to examine participatory policing practices and the responsibilisation of citizens for their neighbourhood safety and security. This exploration of actual practices shows that these often diverge from the intended process and that the blurring of boundaries between police and citizens complicates issues of accountability and normalises suspicion and the responsibilisation of citizens.
