2.Introduction People have embraced communication technologies throughout existence. From cave paintings to smoke signals, telegraphs to emails, human beings have created and developed new communication technologies for the manifestation of a basic human need: To communicate and express themselves. Ironically, however, expression, a basic human need as vital as oxygen, is many times absent from contemporary life. Despite the economic efficiencies that the technologies might have brought about, the ubiquitous mass media and technologies of the present day seem to lead us to a rather schizophrenic experience, something far from the communicative rationality that we have expected. Embraced by the industry, the latest technology, Wireless Computing, has been pervasive throughout the global community. While mobile gadgets are getting smaller, wireless technologies seem to turn the notion of "Personal Computer" into that of "Private Computer." It is private in the sense that it is now possible for devices not only to be used personally, but also to be completely possessed and concealed by the owner, as a part of his or her body. Besides the freedom of movement, do we take such a liking to these new private devices because they seem to amplify our sense of secrecy? Is it this amplified secrecy and its encapsulation of one's psyche that throws us so much into "the ecstasy of communication" that brings billions of dollars to phone companies each year? Attached to the body, yet still connected to public networks, these devices, in the palm or on the ear, suggest a constant oscillation between the public and private domain. A blurring of traditional boundaries that separate the two realms, along with a high frequency of oscillation, brings us a sense of uncertainty as to whether or not we are in "public" or "private", both physically and psychologically. Besides the emerging concerns with privacy issues,it is apparent that it will fundamentally affect our psyche and alter the whole socio-political landscape, as TV and the Internet have done in past decades. One phenomenon is "SMS" (Short Messaging Services), a system that allows people to send short text messages to each other via cell phones. The text message lends itself perfectly to the idea of anonymity and secrecy because of its lack of personal signature, unlike audible voices. SMS has become prevalent throughout Europe and Asia: Business Week, June 4, 2000 "Short messaging -SMS- has yet to catch on in the U.S. But Europeans should zap 200 billion notes this year, yielding $10.6 billion for carriers. By 2003, expect 1 trillion messages...10% of (the)messages may have ads or paid contents." | 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 | Appendix | A1 | A2 | A3 | A4 | A5 | A6 | B0 |
