LookOUT screen reader

This is another experiment in pileup query.
I used only the simple search to collect the initial information and the pileups.

Original Query was: LookOUT screen reader

I slightly edited the results and erased duplicates.

Conclusions: Pileups were negligible.
This paper examines some of the pertinent user interaction issues in the context of a new, low cost; Windows screen reader called LookOUT, which has been developed by the authors. There are three principles of screen reader design that are widely accepted. These are: The screen reader should support quick and effective working achieving the goal of 'maximum information, minimum speech'.
There are a number of issues. These include: using screen markers and/or scripts; the use of scripts to produce interfaces for the blind user that are radically different to those provided by the application; and the trying to minimize the number of esoteric keystroke combinations that a blind user has to remember. Each of these areas is considered in more detail below with particular reference to the way the issues are addressed in the LookOUT screen reader. Additional Information When a user moves the cursor around the screen, using the cursor keys, most screen readers speak information appropriate to the action.
The screen reader could easily speak this position and character type information, but this would compromise the maxim of 'maximum information, minimum speech'. In LookOUT this position and character type is optionally provided by tones that are played at the same time as the speech. LookOUT takes advantage of a modern sound card's ability to play wave and MIDI information at the same time.
When the user presses the key combination, the cursor is moved to the location. Given an application screen markers can be set up relatively easily. This can be achieved either by the blind user (exploring the screen using his/her screen reader in screen reading mode) or by a sighted colleague or friend. Thus, for an application that is not supported by the screen reader, a relatively unskilled person can develop a reasonably efficient interface. However, markers only examine appropriate places on the screen and, whilst useful, they do not wholly fulfill the goal of making the application appear to be a specialized talking application. LookOUT supports the use of markers, and markers can be saved for subsequent use with an application. One can view scripting as a more general method of specializing the behavior of a screen reader so that it supports a particular application.
DUAL SCREEN READER AND MAGNIFIER Dual Screen Reader and Magnifier is a voice output screen reader and screen magnification program designed for use by individuals who are blind or have low vision. This program combines the features of LookOUT Screen Reader and Magnus Screen Enlarger...[More Information] 2. LOOKOUT SCREEN READER LookOUT Screen Reader is a voice output screen reader program designed for use by individuals who are blind or have low vision.
Choice Technology and Training have developed a cost-effective alternative to SuperNova or JAWS. The company markets a screen reader (LookOut), screen magnification tool (Magnice). A bundled version, Dual, combines a screen reader and magnification tool in one package.
Interestingly, all these products have been developed by Professor Blenkhorn of UMIST, who created HAL and Lunar in the 1980’s. Professor Blenkhorn has more recently been involved in developing code for Microsoft Narrator, the speech engine bundled with Windows 2000. The LookOut screen reader : Speaks what you type, in a variety of voices Reads e-mails, documents, web pages and CDs Speaks contextual help information Works with popular windows applications, including MS Office, Windows Explorer, email & the web Supports Visual Basic scripting for custom applications. The Magnice screen magnifier : Magnifies whatever appears on the screen (x2 - x16 magnification) Colour inversion e.g. white print on black 1.5b Demo versions and manuals.
Documentation is available in tape, Braille and large print formats. The LookOut cassette provides a gentle introduction to switching on your PC, loading the LookOut screen reader, and using MS Word, email and accessing the web.
