Interaction Design for Pervasive Computing

Introduction

Computers in recent years have evolved from initial oriented applications repetitive tasks and storage of data on large machines based on electromagnets, to the era of personal computers (PCs) used in most households. From here, the third era has begun, being classified as Pervasive Computing. Ubiquity is the property for which an entity exists or is in all places at once. The Pervasive computing and the Internet of Things aims at the integration of new technologies in the environment personal smart devices inserted in daily tasks, making interact in a natural and uninhibited in all situations and circumstances. In this way, it aims to unite the world virtual, real representation, based on ambient intelligence environment and achieving intelligently (Tooker, 2000, 26-28).

This ubiquity and integration of the two worlds are based primarily on the Internet, the network of networks, with different standards and enabling technologies. Internet has also evolved, dizzying from the initial Web, characterized by a static and developed mainly in HTML; through Web 2.0, where it takes the social aspect very important because it is based on user communities, blogs, wikis and other social sites, encouraging collaboration and exchange of information quick on new technologies like AJAX, CSS, JAVA, and P2P. Finally, the evolution comes from the term Web 3.0, used to describe the evolution of use and interaction in the network through different paths, including the transformation of the network in a database, the thrust of intelligence technologies artificial, the Semantic Web, the Geospatial Web or Web 3D (Cam-Winget, 2003, 35-39).

Thus, as discussed in the paper, the improvement in both hardware and software technologies, has allowed more and more powerful devices, allowing its integration into strategic places, or simply used for advanced applications. This evolution can cover new spaces, consider new applications and/or offer new features to users after global intelligent network (Blackwell & Hague, 2001, 150-157).Discussion

Pervasive Computing, also known as ubiquitous computing was first described by Mark Weiser in 1991. The essence of his vision was to create environments full of computers and communication skills are integrated so invaluable to people. At the date, of Weiser described his idea as a future prospect, as technology was not present at that time that was needed to carry it out, but after a decade of progress, these ideas are commercially viable products, even when they were originally criticized. One of the most significant goals of Pervasive computing devices is to integrate computer as possible to make it blend in life daily, and allow users to focus on tasks to do, not the tools they should wear, and may be a revolution that changed the way of life (Ullmer & Ishii, 2000, 3-4).

The sending of computing a "background" has two meanings:

The first is the literal meaning, detailing that computer technology should be integrated in objects, things, tasks and everyday environments.

The second refers to this integration must be done so that these elements to interfere in the activities for which they are used, providing a more comfortable simple and useful of them (Kindberg et ...
