  • Most input/output devices reside the computer case. These devices communicate with what is inside the computer case through cables attached to the case at a connection called a port, sending data and/or instructions to the computer and receiving them from the computer. Most computers have their ports located on the back of the case, but some models put the ports on the front of the case for easy access. The most popular input devices are a keyboard and a mouse, and the most popular output devices are a monitor and a printer. The keyboard is the primary input devices of a computer.

  • This book considers electronic devices applied to process analog signals in in strument making, automation, measurements, and other branches of technology. They perform various transformations of electrical signals: scaling, integration, logarithming, etc. Such devices are considered in tutorials on electronics. The need in their deeper study is caused, on the one hand, by the great demands of extending the range of input signals, as well as increasing the accuracy and speed of such devices, which usually receive insufficient attention.

  • The iRobot Roomba is perhaps the best example of mobile robotics entering the home. It performs a useful task and is relatively inexpensive, and while it doesn’t look like Rosie the Robot on The Jetsons, it does have a charm of its own. The purpose of this book is to introduce robot hacking to people who are interested in programming and modifying their own robot but who don’t want to destroy a functioning Roomba. This “reversible hacking” is device modification that can be undone to return the device to its original state.

  • Ambiguous keyboards provide efficient typing with low motor demands. In our project l concerning the development of a communication aid, we emphasize adaptation with respect to the sensory input. At the same time, we wish to impose individualized language models on the text determination process. UKO–II is an open architecture based on the Emacs text editor with a server/client interface for adaptive language models. Not only the group of motor impaired people but also users of watch–sized devices can profit from this ambiguous typing. ...
