Ubiquitous computing is a post-desktop model where computing is integrated into everyday objects and activities. It allows information access and communication virtually anywhere. Mark Weiser coined the term in 1988 while working at Xerox PARC. Ubiquitous computing aims to make computing mobile and connected through sensors in the environment to enable more effective interaction and analyze user behavior and activities through connected devices like smart TVs and refrigerators. Key challenges include defining appropriate physical interactions and discovering general application features in such a pervasive computing environment.

2. What is Ubicomp ?
 Ubiquitous Computing is a post-desktop model of human-computer
interaction in which information processing has been thoroughly
integrated into everyday objects and activities. Computing is
embedded everywhere in the environment (Computing & processing is
embedded into everyday devices).
 Information access and communication is possible virtually everywhere
 Devices can be connected and networked
 It is also called Pervasive Computing.

3. History:
 Mark Weiser is the father of ubiquitous computing. He coined the phrase "ubiquitous
computing" around 1988.
 He was working as Chief Technologist at the CS Lab of Xerox Palo Alto Research Center
in the late 1980’s and was articulated the current of computing.
 He wrote some of the earliest papers on the subject, largely defining it and sketching
out its major concerns. He developed the initial initiatives of ubiquitous computing in
the form of tabs, pads, and boards, built at Xerox PARC, 1988-1994.

8. How to achieve ubiquity?
• Make computing mobile and connected
• Instrument the person
• Instrument the physical environment

9.  What makes Ubicomp?
• Processing
• Cheaper, faster, smaller, more energy efficient
• Storage
• Big, fast, small in size (Hardware)
• Networking
• Global, local, ad-hoc, low- power, high bandwidth, low latencies
• Sensors
• Types, speed, accuracy, price and robustness
• Displays
• Projection, flexible materials, low power
• Actuators

10.  Challenges to Ubicomp
• Defining the appropriate physical interaction experience
• Discovering general application features
• Understanding interaction in Ubicomp
• Evaluation challenges for Ubicomp

11.  Application themes for Ubicomp
• Context-aware computing
Sensed phenomena facilitate easier interaction
• Automated capture and access
Live experiences stored for future access
• Toward continuous interaction
Everyday activities have no clear begin-end conditions

12.  Summary
• With advanced technology, computing has become an intervention in all
activities and will change life, by putting sensors in the environment
around us became more effective interaction. Now the devices can know
what the user wants through his movements and analyze his activity
Through the mobile can determine the person's behavior
And other smart things such as smart TV, refrigerator, air conditioners
and etc.
