Usually this leads to their limited integration to society as well as limited unassisted control over the environment. The questions “How can someone with severe motor-impairments perform mouse pointer control as accurately and efficiently as an able-bodied person?” and “How can these interactions be advanced through use of Computational Intelligence (CI)?” are the driving forces behind the research described in this paper.

  • Text Editing in UNIX: an Introduction to Vi and Editing
    Text Editing in UNIX A short introduction to vi, pico, and gedit Copyright 20062009 Stewart Weiss About UNIX editors There are two types of text editors in UNIX: those that run in terminal windows, called text mode editors, and those that are graphical, with menus and mouse pointers. The latter require a windowing system, usually X Windows, to run. If you are remotely logged into UNIX, say through SSH, then you should use a text mode editor. It is possible to use a graphical editor, but it will be much slower to use. I will explain more about that later. 2 CSci 132 Practical UNIX with Perl Text mode editors The three text mode editors of choice in UNIX are vi, emacs, and pico (really nano, to be explained later.) vi is the original editor; it is very fast, easy to use, and available on virtually every UNIX system. The vi commands are the same as those of the sed filter as well as several other common UNIX tools. emacs is a very powerful editor, but it takes more effort to learn how to use it. pico is the easiest editor to learn, and the least powerful. pico was part of the Pine email client; nano is a clone of pico. 3 CSci 132 Practical UNIX with Perl What these slides contain These slides concentrate on vi because it is very fast and always available. Although the set of commands is very cryptic, by learning a small subset of the commands, you can edit text very quickly. What follows is an outline of the basic concepts that define vi.

  • Startup Keyboard Shortcuts Press the Key Or Key Combination Until The
    Startup keyboard shortcuts Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears, or Shift until "Safe Boot" appears). Tip: If a startup function doesn't work and you use a third-party keyboard, connect an Apple keyboard and try again. Key or key combination What it does Option Display all bootable volumes (Startup Manager) Shift Perform Safe Boot (start up in Safe Mode) C Start from a bootable disc (DVD, CD) T Start in FireWire target disk mode N Start from NetBoot server X Force Mac OS X startup (if non-Mac OS X startup volumes are present) Command-V Start in Verbose Mode Command-S Start in Single User Mode To use a keyboard shortcut, or key combination, you press a modifier key with a character key. For example, pressing the Command key (the key with a symbol) and the "c" key at the same time copies whatever is currently selected (text, graphics, and so forth) into the Clipboard. This is also known as the Command-C key combination (or keyboard shortcut). A modifier key is a part of many key combinations. A modifier key alters the way other keystrokes or mouse clicks are interpreted by Mac OS X. Modifier keys include: Command, Control, Option, Shift, Caps Lock, and the fn key (if your keyboard has a fn key). Here are the modifier key symbols you can see in Mac OS X menus: (Command key) - On some Apple keyboards, this key also has an Apple logo ( ) (Control key) (Option key) - "Alt" may also appear on this key (Shift key) (Caps Lock) - Toggles Caps Lock on or off fn (Function key) Startup keyboard shortcuts Press the key or key combination until the expected function occurs/appears (for example, hold Option during startup until Startup Manager appears, or Shift until "Safe Boot" appears).

  • Giving Undo Attention
    Giving undo attention Gregory D Ab owd & Alan J Dix HCI Group, Dept. of Computer Science UniversityofYork Heslington, YORK YO1 5DD UK Abstract In this pap er, weinvestigate the problems asso ciated with the provision of an undo supp ort facility in the context of a synchronous shared or group editor. Previous work on the development of formal mo dels of undo has b een restricted to single user systems and has fo cused on the functionality of undo, as opp osed to discussing the supp ort that users require from any error recovery facility. Motivated by new issues that arise in the context of computer supp orted co op erativework, weaimtointegrate formal mo delling of undo with an analysis of how users understand undo facilities. Together, these combined p ersp ectives of the system and user lead to concrete design advice for implementing an undo facility. The sp ecial issues that arise in the context of shared undo also shed light on the emphasis that should b e placed on even single user undo. In particular, we come to regard undo not as a system command to b e implemented, but as a user intention to b e supported by the system. Keywords: Undo support, CSCW, formal methods 1 Intro duction In this pap er we discuss the issue of design options for undo in a group editor, b oth in terms of what is wanted by the users and what is meaningful and p ossible for the system to provide. We explore the extenttowhich the system supp orts the users' intention for undo within the wider context of recovery.

  • Understanding the CLI User Interface
    Understanding the CLI User Interface You can use two interfaces to monitor, configure, troubleshoot, and manage an EX-series switch: the J-Web graphical user interface and the JUNOS command-line interface (CLI). Both of these user interfaces are shipped with the switch. This topic describes the CLI. For information about the J-Web user interface, see [Unresolved xref]. CLI Overview JUNOS CLI is a Juniper Networks-specific command shell that runs on top of a UNIX-based operating system kernel. The CLI provides command help and command completion. The CLI also provides a variety of UNIX utilities, such as Emacs-style keyboard sequences that allow you to move around on a command line and scroll through recently executed commands, regular expression matching to locate and replace values and identifiers in a configuration, filter command output, or log file entries, store and archive router files on a UNIX-based file system, and exit from the CLI environment and create a UNIX C shell or Bourne shell to navigate the file system, manage switch processes, and so on. CLI Help and Command Completion To access CLI Help, type a question mark (?) at any level of the hierarchy. The system displays a list of the available commands or statements and a short description of each. To complete a command, statement, or option that you have partially typed, press the Tab key or the spacebar. If the partially typed letters uniquely identify a command, the complete command name appears. Otherwise, a beep indicates that you have entered an ambiguous command and the possible completions are displayed.
