The XVI-SM System Introduction

Introduction

Welcome to the BEAM XVI-SM computer terminal. The XVI-SM terminal has been designed to allow visually impaired people access to computer systems employing the Unix X-Windows user interface system. The XVI-SM terminal behaves like a conventional X-Terminal but has additional features to magnify the data on the screen and to speak out the data using a speech unit.

This document is designed to give the user an overview of the system, detailed information on the usage of the BEAM magnification and screen reader software is given in other manuals and is available on line.

Operation

The BEAM XVI-SM terminal uses two sets of software to provide access to visually impaired people. The XVI magnification software provides screen magnification and colour changing while the XVISB screen reader software provides speech and object navigation. These two sets of software are described in detail in the appropriate user manuals (XVI user manual and the XVI-SB user manual).

Users with relatively good vision will predominately make use of the magnification software while more severely visually impaired users will predominately use the screen reader software. Each of these software units can be used independently of one another or can be coupled to provide an integrated system.

General Usage

The terminal, by default, is set up to integrate the magnification and speech software. The user can navigate though the objects using the mouse or by using application navigation key presses.

The screen can be zoomed using special key presses up to 8 times normal. Moving the mouse near the edge of the screen will automatically pan the display to show, on screen, the area of interest.

Moving to an object using the application navigation keys or clicking a mouse button will speak the contents of the object and move the screen readers centre of attention to this object. Alternatively pressing the right hand control key in conjunction with the space bar will speak the contents of the object and set the screen readers centre of attention there.

If required the user can use the screen readers navigation keys to move though the objects in an application and speak out their contents and information on them. In order to do this the keyboard should be set to XVI-SB mode by use of the keyboards right hand ALT key. The numeric keypad keys can now be used to move through objects on the screen.

In order to get the screen to automatically pan to show the current screen object, the user can set the XVI magnification systems AUTOMATIC TRACKING option on.

User Configuration

There are a large number of user options both for the XVI magnification and XVI-SB screen reader software. Some of these options are only useful to full speech/braille users. The XVI-SB options can be modified by bringing up the user options menu with the "RCTRL F2" key sequence. Most of the options also have a hot key sequence to operate them.

The default user options are set so that the mouse cursor is "warped" to the current screen readers item of interest. The "Move Mouse "option enables the user to turn on/off this behaviour.

Information on what is happening on screen is spoken by default. This can be turned off with the "Info Speak" option.

By default only the first line of text is spoken. The "Do Speak All "option allows all of the text to be spoken.

By default the XVI-SM software will not manage the windows on the display. This means the user cannot move between windows using the screen readers Next/Previous application commands. Also the screen reader will not warp the cursor to windows that have popped up automatically. This can be enabled using the "Window Manage" option.

By default, if an object has a label associated with it, this is spoken before the data. This can be enabled/disabled with the "Label Display Mode" option.

Normal key presses and Modifier key presses are spoken by default. This can be turned off with the "Speak Keys" and "Speak Modifier Keys" options.
