Example Profile of Paulina

Introduction

The following example was created to help us discuss aspects of the matching and to help us define requirements for the matchmaker. Although the created profile is imaginary, it is based on a persona developed for the AEGIS project. All personas developed for the AEGIS project are under the Creative Commons Attribution-Share Alike 3.0 License. So anyone is free to use these personas and to build new personas based on them or otherwise modify them.

Paulinas Reyes' Profile

Paulina was born blind. The detailed persona of Paulina can be downloaded from the AEGIS website. Information about her technical preferences are described as the following:

  • Uses her PC on a daily basis:
    • Windows XP
    • Checks emails using IE
    • OCR Software
    • Braille embosser
    • Adobe reader speech output
    • Jaws
  • Practically all the time she uses a smartphone:
    • Provides tactile Feedback
    • VOCA to read sms messages

The profile was created by using the EN 1332 Part 4: Coding of user requirements for people with special needs. The decision of using this standard was made, because the standard is manageable and fast to convert. We can use this example for discussion. Profile structure that will be used in Cloud4All is under construction.

The EN 1332 convention have been transcribed into a profile structure that is represented as name, condition, probability and value. For Example:

<!-- Transcription of EN 1332 - preferred method of presentation of visual information (text, symbols or Braille) -->
   
   <preference name="http://gpii.org/ns/up/text_required" condition="" probability="" priority="0.5" >true<preference/>
   <preference name="http://gpii.org/ns/up/braille_output" condition="" probability="" priority="0.5" >true<preference/>

Paulina prefers both text and Braille. She disclaims the presentation of visual information as symbols. In this case priority of using text is 0.5 and the priority of using Braille is also 0.5.

Scenario of Paulina

As presented in Paulina's persona, she uses quite a lot of assistive technologies but she can only do so in her home environment where everything has been set up especially for her. She would like to be able to use the AT in public places as well. Paulina has some problems using Jaws; it occasionally crashes without any apparent reason and can only access certain programs. She is unable to install and start new software without help. Paulina wants to write a job application in the computer centre at school. In this case she uses a desktop pc with the following device characteristics (solutions):

  • Windows Vista
  • Common Keyboard. Keyboard-layout is configured as Azerty (French keyboard layout)
  • Jaws is installed.
  • MS Word is installed.
  • No Braille display is available
  • Headset as well as loudspeaker are connected

At a simple notional level we can define and discuss some aspects of the matching. That means the following things should be configured to Paulina's needs:

1. Paulina is going to write a job application using word. Paulina's profile indicates that her preferred languages is Spanish. The language setting of Word has to be changed to es.

 

<preference name="http://gpii.org/ns/up/preferred-lang" condition="" probability=" " priority="1" >es<preference/>

Challange:

Application specific setting, depends on the context what Paulina is going to do. If she is going to check her emails word has not to be configured. We need more productive discussions about which kind of context do we regard?

2. Paulina's Profile indicates that she prefers both headset and loudspeaker. But she prioritize the use of a headset instead of loudspeaker. Both headset as well as loudspeaker are connected. The playback setting has to changed to loudspeaker.


<!-- Transcription of EN 1332 - preferred device for the speech related information -->

<preference name="http://gpii.org/ns/up/loudspeaker_output" condition="" probability=" " priority="0.2" >true<preference/>			
<preference name="http://gpii.org/ns/up/headset_output" condition="" probability=" " priority="0.8" >true<preference/>	

Challenge: This setting could be progressed either by windows, or graphic controller. How could such a decision solved by the Matchmaker?

3. Paulina's Profile indicates that she prefers Jaws. Jaws is installed and has to be adapted to Paulina's needs.

<!-- Transcription of EN 1332 - preferred reader software -->

<preference name="http://gpii.org/ns/up/screen_reader" condition="" probability=" " priority="1" >jaws<preference/>
	
  • 1332 defines the following user preferences that are related to Windows Narrator only:
    • Announce events on screen (e.g. appearing dialog boxes)
    • Speech output of input characters as they are typed
    • Move mouse pointer to the active item
    • Start narrator minimised
  • In contrast 24751-2 defines the following parameters
    • usage
    • link indication
    • Speech rate
    • Pitch
    • Volume
    • Application for vendor-specific parameters

Challenge: As you can see in the GPII Wiki the list of settings is extensive. It is important for WP204 knowing how preferences look like for using a screen reader e.g. Jaws? Of course a profile should be usable and understandable by the user but in my mind it has to be more than in 1332 or 24751-2. For example: If a user uses placemakers marking a location in a resource it can be hard and also frustrated for him, if he can`t uses his personalized sections or paragraphs.

Solution 1: Use of a Backup Solution: Restore such extensive settings for example of Jaws. The speech rate has to be changed.


4. Paulina's profile indicates preferences for the audio output of links: speak links, different voice, sound effect.

<!-- Transcription of EN 1332 - preferred audio output for links -->

<preference name="http://gpii.org/ns/up/speak_links" condition="" probability=" " priority="1" >false<preference/>
<preference name="http://gpii.org/ns/up/different_voice" condition="" probability=" " priority="1" >false<preference/>
<preference name="http://gpii.org/ns/up/sound_effect" condition="" probability=" " priority="1" >true<preference/>	
  • This preference could be matched with the settings of Jaws. Jaws support this kind of setting within the speech and sound behaviour:
    • The sound behaviour for links can be changed for any kinds of control elements or HTML elements
    • Per default no sound scheme is defined for the html attribute href. This has to be added manually.
    • Per default the control type link is set to speak. To match Paulina's needs it has to be changed to sound. A sound file has to be selected.

Challenge: How can this be done by the matchmaker?

  • Solution: This could be solved by using a backup solution?


5. Paulina's profile indicates that she prefers a speech output rate of 300 decawords per minutes.

<!-- Transcription of EN 1332  - preferred speech output rate decawords per minute-->

<preference name="http://gpii.org/ns/up/number_of_decawords" condition="" probability=" " priority="1" >300<preference/>	

  • Jaws allows an interval between 40 and 150
  • Narrator (Windows) allows an interval between 1 and 9

Challenge:

  • How looks a general preference for speech rate?
  • ISO 24751-2 (Page 84) recommends a default value of 180!
  • Should be considered in the discussion on the registry [1]


6. Paulina's Profile indicates that ALT texts has to be spoken. This preference could be matched with the settings of the sound and speech behaviour of Jaws.


<!-- Transcription of EN 1332  - preferred presentation of ALT text (as in HTML) -->
<preference name="http://gpii.org/ns/up/speak_the_alt_text" condition="" probability=" " priority="1" >true<preference/>

  • This is similar to point 4 links. But I have not found a setting for ALT texts in word documents.
  • Imagine this preference is relevant only for HTML and websites. A matching of this preference is not necessary, because Paulina only wants to write a job application with word.

Challenge:

  • Consideration of such context dependent issues.


7. Paulina's profile indicates that she prefers a high level of description.

<!-- Transcription of EN 1332  - preference for audio description -->

<preference name="http://gpii.org/ns/up/level_of_description" condition="" probability=" " priority="1" >high<preference/>

Challenge:

  • This preference is highly content-dependent.
  • We have to consider this item. Accessible developments will be able to provide different kinds of content for an resource. This could be one Matchmaker!
