When computer engineers draw schematics, they always represent the Internet as a cloud. The origins of this iconography are pretty simple: the Internet is a distributed network, so if you want to send data from point A to point B, the data gets broken into bits (so to speak), and the individual packets are sent any which way, to be gathered up and re-assembled at point B. So you enter the Internet Cloud at one point, you come out of it at another point, but how you got there is totally obscured.Over the years, the Internet Cloud has enveloped the surface of the Earth with wires. You had to plug in, get connected, be in a place where you can connect. You had to go to the Cloud, but now the Cloud comes to you: wireless technology is becoming ubiquitous. Coffee chains and fast food outlets, public buildings and private homes, are all unplugging and connecting to the Internet Cloud via several different wireless formats (Wi-Fi, Bluetooth, etc.). The different formats ultimately do not matter; no doubt they will be replaced as even more robust technologies reach the market. The point is, we will soon be living our lives subsumed by the Cloud.For educators, the Cloud already is looming over the horizon. Duke University recently announced that all incoming freshmen would be given Apple iPods so they can wirelessly download course materials, multimedia, school information (“What’s for lunch at the caf today?”) and so on. At first glance, one might be surprised by the naiveté of the university administration: how could they imagine the mostly bourgeois students of Duke don’t already have iPods? But there’s certainly a value in standardization, and I’m sure they’ve got a plan for the kids who already have one.The convenience of wireless communication with the student body is certainly appealing: the students can take the university with them. But there’s a catch to this: how can the administration, and more importantly, how can the professors, question a student using an iPod in the classroom? And exactly what is that student doing? Checking her class notes? Looking up a movie schedule? Downloading music? And every other student in that class will have the same iPod, and no doubt will have a similar important reason to refer to his or her iPod just when the professor once again explains the structure of a circular argument.So let’s get back to point A. The Internet Cloud will, in only a few years, envelope every last corner of the Earth. There will be no physical location on the planet (except, perhaps, under water), where you won’t already be online. So your mind will always occupy (and be occupied by) two separate and independent metaphysical spaces —the actual and the virtual.Of course, you will argue that people will just put their iPods away. But what about your cameravideo recorder-watch-text messagemultimedia Web browser-cell phone which will also be connected? How could anyone leave home without it?Our students, the information pioneers of our society, will be more and more likely to spend their time in a space that they can shape, where their input has affects, where what they think matters.Have I described your classroom to you?

Ubiquitous Computing (Ubi Comp), or pervasive computing is hyped as the ‘third wave ’ in computing (Weiser, 1996) and is best described by its creator Mark Weiser, (1996, p1) as “ invisible, everywhere computing that does not live on a personal device of any sort, but is in the woodwork everywhere”. Ubiquitous computing therefore attempts to create technologies that mar the boundary between the users experience with computing and the world by becoming one with it. There are a number of ubiquitous computing research branches such as mobile computing, wearable computing and the intelligent environment. Ubiquitous computing is reputed to evolve our business, learning, entertainment, collaborative and home environments by embedding smart technologies that interact with us quietly behind the scenes (Roussos et al, 2003). The vision is of smart embedded technology grounded in the realizable theory where microprocessors are becoming smaller, less expensive and able to incorporate into everyday objects and environments such as clothes, pencils, paper, toys, tools, home and office appliances, walls, floors and fixtures (Mattern & Strum, 2003). Wireless technologies will be the enabler for these devices and environments seamlessly communicating with other smart devices or services over the internet (Mattern & Strum, 2003). User interfaces will consist of speech or gesture recognition systems designed to blend into the world and require little knowledge for users to accomplish

Ubiquitous computing refers to a twenty‐first‐century era of computing in which networking and computing technologies become so small, fast, interconnected, and cheap that they can be seamlessly embedded into the environment and everyday objects. It implies that computing will become ubiquitous. User‐friendly services are expected to be available anytime and anywhere and only when demanded by users. This implies that computing will become intelligent because it will need to understand human behavior in context. The term “ubiquitous computing” was coined by Mark Weiser (1952–1999), chief scientist at the Xerox Palo Alto Research Center (PARC) in California, in a seminal paper published in 1991 (→ Human–Computer Interaction; Information Society; Technology and Communication).

From first recognizing the idea of a world in which ubiquitous computing would be a reality to the final version of this book more than five years have passed. A very long list of people contributed to this work and I would like to express my gratitude to everyone involved-I enjoyed and appreciated every single minute of their time they made available.

De snelle technologische evolutie op het vlak van hardware en software enerzijds en computercommunicatie anderzijds heeft reeds meerdere malen geleid tot drastische wijzigingen bij het gebruik van de informaticatechnologie. In een periode van ongeveer 60 jaar kunnen reeds drie merkwaardige evoluties worden waargenomen: de mainframe evolutie, de personal computer (PC) evolutie en de Internet (r)evolutie. Na deze drie evoluties blijven computers nog steeds moeilijk toegankelijke objecten. Ubiquitous computing (Ubicomp) heeft als doelstelling om computers beter te integreren in het dagelijks leven van de mens. Computers zullen worden ingebouwd in allerhande gebruiksvoorwerpen en reageren onmiddellijk op wijzigende externe gebeurtenissen. In dit artikel bespreken we de evolutie naar ubiquitous computing en een aantal sociale risico’s van deze evolutie. Bovendien beschrijven we enkele belangrijke technologische uitdagingen en mogelijke oplossingen.

Weiser’s vision "Ubiquitous computing names the third wave in computing, just now beginning. First were mainframes, each shared by lots of people. Now we are in the personal computing era, person and machine staring uneasily at each other across the desktop. Next comes ubiquitous computing, or the age of calm technology, when technology recedes into the background of our lives.” Mark Weiser,

As we look to the future of computing, and particularly to the future of HCI research, the vision of ubiquitous computing emerges as a principal theme. The focus of this workshop is applications-centered research in ubiquitous computing. We define ubiquitous computing as the attempt to break the pattern of traditional relationships between users and computational services by extending the computational interface into the user's environment. Over the past few years researchers in wireless networking and distributed systems have worked to build infrastructures supporting mobile and ubiquitous computing. Infrastructure research is, of course, necessary for the advancement of ubiquitous computing, but we must also examine higher-level issues such as the kinds of tasks and interaction patterns that emerge as the user is allowed to break away from the desktop.

This mixed methods study explored the relationship between ubiquitous computing and the systemic transformation of a high school focused on 21st century teaching and learning. Previous research studies focused on the benefits of 1:1 laptop environments: however, many schools implemented ubiquitous computing without a systems approach. Many 1:1 laptop studies have focused on gains in student academic performance on standardized exams, a metric that some suggest is the wrong focus. This study was conducted at a suburban high school in eastern Pennsylvania with over one thousand students in grades nine through twelve and about 66 high school teachers. The study explored changes in teacher and student technology use, the relationship between teachers' technology use and the acquisition of 21st century skills, and factors that influenced teachers' decisions to plan lessons that integrate student-centered technology use in a ubiquitous computing environment. An investigation of 21st century skills, the need for school reform, and the value of ubiquitous computing to teaching and learning themes are shared. In March 2012, the administration presented a plan to the School Board of Directors for a 1:1 laptop deployment. The presentation focused on the need for 21st century learning in order to prepare students for their future. Opposition from some stakeholders questioned the value of technology and the costs to the local taxpayers. However, the School Board supported the proposal with an expectation that the administration would measure results to demonstrate the educational value of this expenditure. The district purchased the additional laptops and created a ubiquitous computing environment during the fall of 2012. In order to meet the expectation of the School Board, quantitative historical data collected through surveying teachers and students during the first year of implementation was analyzed. Historical walkthrough observation data was also analyzed to triangulate the data; comparing self reported technology use from the questionnaires to observed use. Personal interviews were conducted during the study, the second year of implementation. Interviews collected explanatory qualitative data, to better understand questions that emerge from the analysis of quantitative data, any perceived barriers to implementation of classroom instructional technology, and factors that contributed to teacher decisions for lesson planning designed to utilize technology for teaching and learning. Utilizing a pragmatic approach that explored the shared experiences of teachers for the phenomenon of ubiquitous computing, the results may inform others planning to use systemic approaches to transform schools to 21st century teaching and learning.

Computer technology continuously advances and it enters people’s lives more and more as they get better and we can perform certain tasks faster with them, or can perform certain tasks automatically. The existence of computers is due to people because people created them and people are using them. Computer technology and computers probably wouldn’t have a meaning in whatever they do without people’s needs for them either directly or indirectly. We may benefit from computers directly when their benefits are directly due to them such as using a word processor to accomplish our tasks (e.g. writing a report or paper), while we can benefit indirectly when we eventually get benefits due to having computers processing tasks for us but the connection is not that obvious. For instance, some products IKEA sells are cheaper due to computers because with the help of computers certain tasks in production require less effort. Humans and computers together could be viewed as a system, where they affect one another. Ubiquitous computing 1 (ubicomp, for short, as Weiser uses it in [18]) is about computers everywhere surrounding humans, communicating with each other and interacting with people in certain ways. One of the main goals of ubiquitous computing is
