Mobile media

Mobile media is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mobile media rather than just read about it. In short: Mobile media has been defined as: "a personal, interactive, internet-enabled and user-controlled portable platform that provides for the exchange of and sharing of personal and non-personal information among users who are inter-connected." The notion of making media mobile can be traced back to the “first time someone thought to write on a tablet that could be lifted and hauled – rather than on a cave wall, a cliff…

Key takeaways

  • Mobile media belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Mobile media to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Mobile media from memory before moving on to harder problems.

Reference excerpt

Mobile media has been defined as: "a personal, interactive, internet-enabled and user-controlled portable platform that provides for the exchange of and sharing of personal and non-personal information among users who are inter-connected." The notion of making media mobile can be traced back to the “first time someone thought to write on a tablet that could be lifted and hauled – rather than on a cave wall, a cliff face, a monument that usually was stuck in place, more or less forever”. In his book Cellphone, Paul Levinson refers to mobile media as “the media-in-motion business.” Since their incarnation, mobile phones as a means of communication have been a focus of great fascination as well as debate. In the book, Studying Mobile Media: Cultural Technologies, Mobile Communication, and the iPhone, Gerard Goggin notes how the ability of portable voice communication to provide ceaseless contact complicates the relationship between the public and private spheres of society. Lee Humphreys' explains in her book that now, "more people in the world today have a mobile phone than have an Internet connection".

History The development of the portable telephone can be traced back to its use by the military in the late nineteenth-century. By the 1930s, police cars in several major U.S. cities were equipped with one-way mobile radios. In 1931, the Galvin Manufacturing Corporation designed a mass market two-way radio. This radio was named Motorola, which also became the new name for the company in 1947. In 1943, Motorola developed the first portable radiotelephone, the Walkie-Talkie, for use by the American forces during World War II. After the war, two-way radio technology was developed for civilian use. In 1946, AT&T and Southwestern Bell made available the first commercial mobile radiotelephone. This service allowed calls to be made from a fixed phone to a mobile one. "Many scholars have noted and praised the mobility of reading brought about the emergence of the book and the advent of early modern print culture". Along with the book, the transistor radio, the Walkman, and the Kodak camera are also bearers of portable information and early examples of mobile media consumption. With the rise of the internet, many forms of media can be considered mobile. Forms of mobile media, such as podcasts and even social networking services, are some of the few that can be downloaded, used or even streamed over the internet. According to Jordan Frith and Didem Ozkul in their book, Mobile Media Beyond Mobile Phones, they believe that mobile media has moved beyond our past knowledge of mobile media. "With this issue, we realized that not only has our understanding of mobile media expanded beyond the mobile phone, but our thinking of the 'mobile in front of media has evolved". From The Mobile Reader, Jason Farman and other authors describe this expansion of mobile media. "The cultural shift that happened in conjunction with the printing press can be mapped onto our uses of mobile media (especially location-aware technologies): the cultural imaginaries of space became simultaneously about experiencing the expansion of space, an increase in speed of transmission, and a transformed view of the local". For a time, mobile phones and PDAs (Personal Digital Assistants) were the primary source of portable media from which we could obtain information and communicate with one another. More recently, the smartphone has rendered the PDA obsolete by combining many features of the cell phone with those of the PDA. In 2011, the growth of new mobile media as a true force in society was marked by smartphone sales outpacing personal computer sales. With this non-stop consumption of new and improved smartphones, theorists such as Marsha Berry and Max Schleser explain that these change the way we can do things in life. "With the rise of smartphones in 2007 and proliferation of application through Apple's App Store and Android Market in the following year, how citizen users and creative professionals represent, experience and share the everyday is changing". While mobile phone independent technologies and functions may be new and innovative (in relation to changes and improvements in media capabilities in respect to their function what they can do when and where and what they look like, in regard to their size and shape) the need and desire to access and use media devices regardless of where we are in the world has been around for centuries. Indeed, Paul Levinson remarks, in regard to telephonic communication, that it was “intelligence and inventiveness" applied to our need to communicate regardless of where we may be, led logically and eventually to telephones that we carry in our pockets”. Levinson credits the printing press for disseminating information to a mass audience, the reduction in size and portability of the camera for allowing people to capture what they saw regardless of their location, and the Internet for providing on-demand information. Smartphones have altered the very structure of society. "With this issue, we realized that not only has our understanding of mobile media expanded beyond the mobile phone, but our thinking of the 'mobile' in front of media has evolved". The ability of smartphones to transcend certain boundaries of times and space has revolutionized the nature of communication, allowing it to be both synchronous and asynchronous. These devices and their corresponding media technologies, such as cloud-based technologies, play an increasingly important role in the everyday lives of millions of people worldwide.

Worked examples

Example 1 — a first encounter with Mobile media

Start with the simplest possible case. Write down what Mobile media claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mobile media before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mobile media ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mobile media

In research
Mobile media appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Mobile media in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Mobile media is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mobile computing, Mobile phones, Multimedia, so understanding it makes those chapters shorter.
In everyday life
Look for Mobile media outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
