Smartphones

Posted by cheyingtan on September 6, 2013 No comments

The mobile, a phenomenon when it was first introduced to the world and now a gadget most people cannot live without. With us for generations and will be with us for generations to come, but so much has changed since the first mobile. 

The first mobile, a big, bulky gadget with a huge aerial and very little features. The mobiles of today, a Smartphone. Technology has grown a huge amount since its first appearance and the mobiles have done the same. As Smartphones were introduced the mobile world became more exciting and more appealing and now whatever sort of person you are or whatever sort of things you like there is a Smartphone for you. 

The Smartphone is generally based on an Operating System which gives it the ability to run applications, therefore offering even more. The Operating Systems themselves, Android, Windows, Blackberry, offer a whole host of features and then there is even more in the Smartphone itself. You can now access the internet and check out your favourite Social Networking sites, take photos and videos without the need of a camera or video recorder and have Apps that cover every aspect of things you might want to know or do.

With regular mobile phones looking and functioning the same as Smartphones it is difficult to show the difference between them both. The Operating System would be a big clue as to how to spot a Smartphone and would probably be the best way to pick one from a crowd, but also sometimes a QWERTY Keypad or an onscreen QWERTY Keypad lets you identify one. 

The Smartphone sounds like an intelligent phone designed for intelligent people, but this is far from correct.

It is an intelligent phone but offer a variety of everything for every type of person. Yes an intelligent business man would benefit hugely from this sort of phone with the ability to browse his emails and view and even amend documents, but with the thousands of Apps and Games on offer from the Operating Systems and the Smartphones themselves, these mobile phones are for everyone and anyone.

Essay: Human Computer Interactions

Sample Essay

Human Computer Interactions defines the study of interactions between Human and Computers. The term Human-Computer Interaction is often used interchangeably with “Man-Machine Interactions” (MMI) or “Computer to Human Interaction” (CHI). The subject of Human-Computer Interactions is wide and multi-disciplinary  as well as complex, which not only include the research into impacts of CHI in an organizations, Into the designing approaches of CHI, Methodologies and Matching models for performing tasks and inclusion of  research from other fields of studies as well as research into Interactional Hardware and Software (Carroll, 2009).

The study of HCI is firstly and more importantly concerned with both software and hardware used in implementation of various interactional techniques and technologies.  While in the past years, the most common hardware device for interacting with the computer has been the keyboard and the mouse, The HCI research has made it possible for the design and the development of new devices which present new possibilities of interactions with computers. However these devices also present a new set of problems as well.  The addressing of these problems as well as their effect on the communication between the use and the computer is one of the central issues of the HCI.  In other words, it aims at developing interactional techniques as well as suggests where and in what situations they can be put to best use.  Furthermore, the study of HCI is also concerned with how the users interact with the computers.  The core problem for HCI to solve is the matching of computer’s model to that of users. For this purpose it is required for both parties to have a mutual knowledge of the problem at hand. 

The research in HCI has mostly focused on finding out the knowledge required by the user and how this knowledge is applied to the computer in order to predict and describe the behavior of the user at the interface of human and computer interactions.

In short, the purpose of HCI is to enable the designers to build more usable system by making explicit the model used by the user to perform different task on the computer system. The research conducted on the subject of HCI also concerns the design of system interface fulfilling the information needs of the user as well as allowing them the freedom to perform task as they want to do it.  This measure of fit a task design around the informational needs of the user is one of the major determinant of the success and failure of any HCI hardware or software. Hence, another purpose of HCI  studies is to develop methods that can be used to determine users’ needs , in order to ensure that the computer system provide the users with the functionality they need as well as the information they require as well as in the form that they desire.
