The author gives an example of a conference room where different devices such as projectors, computers, etc. they can be added and disconnected from a computer system that manages all room operations. You will need to turn off your computer in order to install software updates and additional features. A possible scenario in which such a computer never shuts down and continues to function is ideal. This will allow systems to blend flawlessly into the human environment and achieve “embodied virtuality.” The author also mentions an alternative approach where micro-kernel operating systems [1] meet the dynamic needs of pervasive computing. Another suggestion from the author is to change the protocols used by operating systems to interact with applications. [1]The author mentioned the use of "virtual reality" to implement ubiquitous computing techniques. The approach had two flaws. First, simulations could not produce authentic results at lower costs. Secondly, it creates a fake world for its users that it is not close to
