The Global Public Inclusive Infrastructure will provide a platform that will allow any platforms, applications and devices to automatically activate their accessibility features. Any ICT solution can integrate with the GPII in an easy way, therefore becoming automatically launchable and configurable. This presentation describes the steps needed to integrate any ICT solutions with the GPII.

1. GPII Integration

2. Integrating Your Application
• You can usually integrate your app without
writing any code
• Simply describe:
1. Which platforms you support
2. How you store your settings
3. How to launch and stop your
application
4. How your settings relate to a common
vocabulary

4. Basic Structure:
{
"name": "Windows Built-in Screen Magnifier",
"id": "com.microsoft.windows.magnifier",
"contexts": (…),
"settingsHandlers": (…),
"lifecycleManager": (…)
}

5. Give your application a name and a unique ID:
{
"name": "Windows Built-in Screen Magnifier",
"id": "com.microsoft.windows.magnifier",
"contexts": (…),
"settingsHandlers": (…),
"lifecycleManager": (…)
}

6. Describe the platforms your application runs on:
{
"name": "Windows Built-in Screen Magnifier",
"id": "com.microsoft.windows.magnifier",
"contexts": {
"OS": [
{
"id": "win32",
"version": ">=5.0"
}
]
},
"settingsHandlers": (…),
"lifecycleManager": (…)
}

7. Describe how your app stores its settings:
{
"name": "Windows Built-in Screen Magnifier",
"id": "com.microsoft.windows.magnifier",
"contexts": (…),
"settingsHandlers": [ {
"type": "gpii.windows.registrySettingsHandler",
"options": {
"hKey": "HKEY_CURRENT_USER",
"path": "SoftwareMicrosoftScreenMagnifier"
},
"capabilitiesTransformations": (…)
}, {...} ],
"lifecycleManager": (…)
}

8. Describe how to start and stop your app:
{
"name": "Windows Built-in Screen Magnifier",
"id": "com.microsoft.windows.magnifier",
"contexts": (…),
"settingsHandlers": (…),
"lifecycleManager": {
"start": [
"setSettings",
{
"type": "gpii.launch.exec",
"command": "${{environment}.SystemRoot}System32Magnify.exe"
}
],
"stop": [
{
"type": "gpii.launch.exec",
"command": "${{environment}.SystemRoot}System32taskkill.exe /im Magnify.exe"
},
"restoreSettings"
]
}
}

10. AccessForAll & Common Terms
• AccessForAll a.k.a. ISO 24751
• Open registry-based architecture in
progress
• Provides a common vocabulary for
describing a user’s needs and
preference
• Provides a “meeting place” for cross-
platform preferences
• Philosophy: you speak your preferred
language, but describe how to translate

11. {
"http://registry.gpii.org/common/magnification": [
{"value": 3.0}
],
"http://registry.gpii.org/common/tracking": [
{"value": "mouse"}
],
"http://registry.gpii.org/common/invertImages": [
{"value": true}
]
}
Eexample preferences set:

12. {
"http://registry.gpii.org/common/magnification": [
{"value": 3.0}
],
"http://registry.gpii.org/common/tracking": [
{"value": "mouse"}
],
"http://registry.gpii.org/common/invertImages": [
{"value": true}
]
}
… But the windows magnifier stores magnification as a
percentage

13. “$HKEY_CURRENT_USERSoftwareMicrosoftScreenMagnifier”: {
“Magnification”: 200, [REG_DWORD INT]
“Invert”: 1 [REG_DWORD BOOL],
"FollowMouse": 1 [REG_DWORD BOOL]
}

15. Defining how to translate and set settings:
{
"name": "Windows Built-in Screen Magnifier",
"id": "com.microsoft.windows.magnifier",
"contexts": (…),
"settingsHandlers”: [
{
...
"capabilitiesTransformations": {
"Magnification": {
"transform": {
"type": "gpii.transformer.linearScale",
"inputPath": "http://registry.gpii.org/common/magnification",
"outputPath": "value",
"factor": 100
}
},
...

16. Defining how to translate and set settings:
{
"name": "Windows Built-in Screen Magnifier",
"id": "com.microsoft.windows.magnifier",
"contexts": (…),
"settingsHandlers”: [
{
...
"capabilitiesTransformations": {
"Magnification": {
"transform": {
"type": "gpii.transformer.linearScale",
"inputPath": "http://registry.gpii.org/common/magnification",
"outputPath": "value",
"factor": 100
}
},
...

}
},
...
Take this preference
Rename it to this setting
