Keyboard, mouse History of Keyboard and a Mouse Ergonomic Keyboard Stress Management techniques Practical concerning windows commands and a Notepad Lecture 4 Overview Today’s topics are, Reasons why some computer users prefer alternative methods of input over a standard keyboard or mouse. Input data by touch Game controllers Input data by light Other input types, . audio, video etc. When to use which input device? Practical Introduction There are a huge range of input devices on the market These fall into two main groups Manual Input and Automatic data capture Introduction Manual Input include devices such as the keyboard and mouse, where the user has to put the data in by hand. Automatic Data Capture devices collect the data automatically and feed it straight into a computer. Some of them are operated by people, like bar-code scanners, but some devices just collect data, such as web cams and data loggers. Benefits of entering data in other ways Automatic data capture tends to cut down on errors compared to manual data entry. It is usually quicker too – imagine how long the supermarket queue would be if every number on the bar-code had to be typed by hand. However, they tend to be more expensive, and so are usually used when there is a lot of data to capture. When to chose which device? Sometime the decision to choose input device is optional, sometimes it becomes mandatory. For example in a dusty factory, decision to choose decision to choose a standard keyboard and a mouse can be damaged if it becomes clogged with dirt. Input data by Touch Various devices exists in this category. Light Pen Touch screens Trackballs Keyboards Graphics tablets Game controllers Concept keyboards Light Pen Users may use Tablet PC Input Panel to enter text and use the tablet pen to point. A tablet light pen is a computer input device in the
