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.

This chapter addresses the changing nature of surveillance by way of user-generated images, especially caught-on-tape style photographs and videos captured on mobile phones. Through a discussion of examples from Turkey (as well as from around the world), this chapter discusses the emergent function of the camera phone as a tool of surveillance used to document the misconduct of other individuals or authority figures. Aligned with the complex, decentralized networks of the synoptic paradigm rather than the more static, closed model of the Panopticon, camera phones intensify the visibility of anyone, anytime, anywhere. They facilitate 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. One could assume that camera phones and these new socio-technological practices they permit are empowering the individuals. However, by engaging in sousveillance, individuals become implicit partners in surveillance society.

Poverty alleviation has become one of the biggest challenges for many countries and access to financial services is considered to be a key driver of development and economic growth. Finding solutions that can break down barriers that poor people are facing to access formal financial services has become a major concern for researchers, governments, financial institutions. Financial services must reinvent themselves and the adoption of new technology is a crucial key to overhaul their operations and to find innovative solutions to manage customer expectations. The escalation in access and penetration level of mobile phones and the Internet can improve financial inclusion by facilitating easy access to financial services, by providing secure transaction platforms, by reducing transaction costs, by providing a competitive business framework. There has been relatively limited research on the impact of Internet and mobile phones use on financial inclusion, therefore our main purpose was to investigate this linkage in a sample of 11 post-communist countries of the European Union from 1996–2017 using panel cointegration and causality analyses. Firstly, we investigated whether mobile cellular phone subscriptions and the rate of Internet usage affect financial institutions’ access; secondly, we analysed the impact of these variables on financial market access. Results indicate that mobile cellular phone subscriptions positively affect both financial institution access in countries like Hungary, Latvia, Lithuania, Poland, and Slovenia and financial market access in Bulgaria, Croatia, and Hungary. Also, a negative relationship between mobile cellular phone subscriptions and financial institution access was noticed in the Czech Republic and regarding financial market access in the Czech Republic and Poland. Our findings also indicate both positive and negative relationships between Internet usage rates and financial institutions and financial markets access. By increasing Internet usage we can improve access to financial institutions in Bulgaria, Croatia, Czech Republic, Hungary, and Poland and we can increase financial markets access in Latvia and Slovenia.

Technological Developments

More and more people are using mobile (cellular) phones and the world is increasingly becoming unwired due to diffusion of this technology. The cellular technology is present in most Asian countries since 1980s. However, its diffusion process in these countries has largely been affected by technological developments, i.e., transition from analogue to digital, and regulations. The nature of regulations relate to spectrum licensing and the number of competitors allowed by respective governments. These regulatory decisions may explain the current structure of mobile phone industry in most of these countries. The popularity of cellular communication lies in its appealing advantage as compared with the fixed networks. The most important feature of a cellular phone is its portability in that the call is made to a person and not to a place. In developed countries, the features available on mobile handsets (such as caller line identification, voice mail, call forwarding, call waiting and the facility of receiving and transmitting short text messages) are available free of charge. However, these cell phone facilities are very costly in developing countries as compared with their fixed networks. The regulatory licensing structure prevailing in these countries partly explains this price differential. In effect there has been wide diversity in the speed of introduction of mobile phones and their diffusion across developing countries, which has not been explored. Gruber and Verboven (1998) has recently examined diffusion of cell phones in the European Union. However, this is a neglected area of research in developing countries.

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.

Information Media

Short Message Service (SMS) is a technology that provides service for sending and receiving messages between cell phones. Every individual, government, private or educational institution cannot be separated from using SMS as one of the information media. One of them is meeting notification information. But SMS technology can only carry limited data. SMS Gateway is a system that bridges mobile phones with the system that becomes a server with SMS as the information. In the SMS Gateway work system, the user's cellular phone sends an SMS containing the written format to access the information needed through the GSM network. The SMS will be received by the SMS Gateway cellular phone which will then be retrieved by the PC using the mfbus protocol via a data cable. Up to the PC, the text format will be processed by the SMS Gateway application program to produce information that will be sent to the SMS Gateway cellular phone using the mfbus protocol via a data cable. After that the information is sent by the SMS Gateway cellular phone to the user's cellular phone. With the SMS Gateway-based meeting notification application, it can provide detailed and concurrent notification of meeting information so that each meeting member can follow according to his schedule.

The growing ubiquity and usability of smart mobile phones can be exploited to develop popular and realistic pervasive computing applications. Adding image processing capabilities to a mobile phone equipped with a built-in camera makes it an easy-to-use device for linking physical objects to a networked computing environment. This chapter describes an extensible and portable programming platform that, using bi-dimensional visual tags, turns mass-market camera-phones into a system able to capture digital information from real objects, use such information to download specific application code, and act as a GUI for interacting with object-dependent computational services. The system includes a module for on-phone extraction of visual coded information and supports the dynamic download of mobile applications.

Correct Recognition Rate

The availability of camera phones provides people with a mobile platform for decoding bar codes, whereas conventional scanners lack mobility. However, using a normal camera phone in such applications is challenging due to the out-of-focus problem. In this paper, we present the research effort on the bar code reading algorithms using a VGA camera phone, NOKIA 7650. EAN-13, a widely used 1D bar code standard, is taken as an example to show the efficiency of the method. A wavelet-based bar code region location and knowledge-based bar code segmentation scheme is applied to extract bar code characters from poor-quality images. All the segmented bar code characters are input to the recognition engine, and based on the recognition distance, the bar code character string with the smallest total distance is output as the final recognition result of the bar code. In order to train an efficient recognition engine, the modified Generalized Learning Vector Quantization (GLVQ) method is designed for optimizing a feature extraction matrix and the class reference vectors. 19 584 samples segmented from more than 1000 bar code images captured by NOKIA 7650 are involved in the training process. Testing on 292 bar code images taken by the same phone, the correct recognition rate of the entire bar code set reaches 85.62%. We are confident that auto focus or macro modes on camera phones will bring the presented method into real world mobile use.
