The Social Construction of Technology (or SCOT) is a new research tradition rooted in the sociology of technology. SCOT provides a multidirectional model based on the property of interpretive flexibility and emphasizes social influences on the design and development of technology. This paper will apply the SCOT principles to explore the development of the mobile phone, historically define the development of the mobile phone in three different phases, and accordingly analyze the interpretive flexibility of the mobile phone in the three different phases. Based on the SCOT theory, this article will discuss how the original huge cell phones are shaped and developed by social influences on smartphones in today's life. In 1983, Motorola launched its first cell phone, known as the Motorola DynaTAC 8000X, which offered 30 minutes of battery life. of talk time, six hours of standby time and can store 30 phone numbers. At the time, cell phones were extremely expensive: the DynaTAC 8000X cost $3,995, and cellular networking was limited. To analyze the development and interpretive flexibility of the mobile phone in its early stage, we must first introduce the social groups that were linked to the artifact. The users of the artefact constituted the most important social group. At the time, users mainly consisted of businessmen, managers, politicians, doctors, large companies, military personnel, etc. who had a high income and needed to stay in contact with others occasionally. For them, cell phones were the extension of corded phones that helps maintain communication without range limitations. Therefore, the problems that this social group has had with cell phones are quite clear. Cell phones were too big and heavy, talk time was too short for regular users and the number...... paper......1fS3NiLAE&sig=n5NJOhab0TTbBoXm MGv7xddRqAU&hl=en&sa=X&ei=6-JxUr_oOoqPiAKg8oGYDg&ved= 0CHYQ6AEwBA#v=onepage&q=price%20of%20cell%20phone%20in%201980s&f=false Chowdhury.
