'''Intro'''
Ubiquitous computing is a post desktop model of human computer interaction in which the information processing is part of people’s day-to-day activities and operation.
Computers are getting faster, smaller, more efficient, and cheaper which will result in computers in everything (ubiquitous). This is already happening, and as it grows computers will become invisible, embedded in everything, and connected together. They will also become intelligent to changes in their surroundings (ambient intelligence).
One of the main key points of ubiquitous computing is to make the machine adjust to the human world. To make machines a part of daily life without people noticing it.
Some of the devices that we use with the ubiquitous computing model are cell phones, mp3, GPS and interactive whiteboards. These are great examples that demonstrate the ubiquitous computing model. People use all of these devices daily. However, they don’t think about the fact that those are actually machines. It’s integrated in our lives.
This essay will elaborate further on Ubiquitous computing. Ubiquitous computing is the future of computer products. Moreover, consumers will likely to purchase something that is familiar to them and seems less like a machine. Users are forcing a paradigm shift that demands consumer products to embrace the principles of ubiquitous computing.
Ubiquitous computing aims to integrate itself into everyday life, and everyday life is not a single threaded linear event. In the daily lives of an average user, there are many interruptions, stoppages, and unexpected occurrences. Users also need to take breaks during their activities, or even want to put an activity on hold. Sometimes an activity can be put on hold for long durations or permanently. Regardless of the durations or the frequency of interruptions to an activity, the ability to resume an activity after an interruption must exist. Users also expect the service to resume the activity with all previous progresses intact. What this means is that when a service pauses an activity or process it must save all progress done on the activity and any settings that might be created for the activity. When the activity resumes all the saved data must be readily available, and the activity should resume as if no interruption had occurred. Furthermore, when an activity had been paused for a long duration, the user might forget previous progress and the service should be aware of the passage of time, and reacquaint the user with the activity and its progress. In addition, users also require continuously available services, as today’s paradigm move toward the infusion of ubiquitous computing into our everyday lives, the services provided will need to become constantly available, always interrupted and easily resumed. The manner of the service resumption is also paramount in the successful integration of ubiquitous computing. The service must be able to start in one location, paused, resumed at a completely different location with a different interface and a different computer. Only when all of those capabilities are meet, then true integration into ubiquitous computing will be possible, and accepted by the users.
'''Natural user interface'''
People prefer computers that conform to them rather than conforming to computers. A Natural and easy process in learning how to use a device is crucially important in a product. If the learning process is too complex or take too much time; the users won’t want to use the product and will search alternatives for it. The purpose of Natural user interface is to make the user feel like a natural.
'''Tablets and iPad example'''
The idea of tables exited before the iPad came along. However, the iPad has exploded in the market. iPad are extremely popular and people find them easy to use. The key element of the iPad’s success lies within its great user interface that allows people and a natural and comfortable usage. Natural interaction of screen is what made it successful
