What is Ubiquitous Computing? l l “Ubiquitous computing is the method of enhancing computer use by making many computers available throughout the physical environment, but making them effectively invisible to the user”.  The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it. 
What is Ubiquitous Computing? l l Human interaction with the environment and no need for knowledge that a computer is involved. A large array of computers (from tiny computer chips to super computers) seamlessly and transparently used in all aspects of our everyday lives.
What Ubiquitous Computing is not l The analogy that is often held up as an example of Ubiquitous Computing is the refrigerator that can tell you when to buy more milk.  l …stark contrast between the marginality of the enhancements and the complexity of the computing infrastructure required to achieve them. 
Requirements for Ubiquitous Computing l l Natural interfaces – “We desire natural interfaces that facilitate a richer variety of communications capabilities between humans and computation. ” Context-awareness – “Ubicomp applications need to be context-aware, adapting their behavior based on information sensed from the physical and computational environment. 
Data Capture Problems l Electronically capturing the hand movement is relatively easy using special pens, inks and tablets. But interpreting and manipulating those strokes as words and numbers or other symbols is much more difficult.
Data Capture Problems l l l Electronic Whiteboards, audio and video devices, pens and tablets, new types of ink and other devices are being developed and tested.  Researchers are also working on basic programming support for audio, video and pens to parse and interpret that information.  Basic information about the user (Active Badges, RFID)
Location awareness l Location awareness is an important aspect of Ubiquitous Computing. The most well known example is the Global Position System (GPS) device that can report where it is anywhere in the world. But there has also been research into Active Badges  and other location aware devices.
Other areas that need to be explored l Context Fusion l Audio/video l Merging of multiple forms of media will add value to the Ubiquitous Computing environment.
e. Mail Example l l Multiple points of input Multiple providers Must still enter URL, username, password Wearable devices could change that and provide “natural Interfaces” but what about personal information security?
Conclusion l l l Standards must come first Personal information Video storage will have to be advanced
