About

This is a dumping ground for crazy ideas. Suitable for farming out to interns, Google SoC folks, or eager community members.

Core Software

Accessibility Support

Sugar currently doesn't have anything available for the visually impaired.

Speech Synthesis integration into Sugar

Integrate speech synthesis with all activities, not just Speak, and provide for karaoke coloring. See Mokurai's article on adapting Same Language Subtitling for literacy to the XO.

Desirable Features for Sugar Speech Synthesis Plugin:

  • Provide Sugar Speech Synthesis Configuration Management Tool
  • Karaoke Style Coloring in Sugar Environment
  • UI for configuration Control
  • Accent gets set on the basis of locale

Java

Package and integrate the IcedTea open source bootstrap of OpenJDK Java with browser plugin for the XO. Deliverables would include:

  • Binary, source and rpm dependencies for icedtea and icedtea browser plugin
  • Java enabled os image
  • Integration of packages into autobuild branch

Print Support

Print support in Sugar would be useful in many scenarios. The ideal project deliverables would include

  • Integration of a printing infrastructure (CUPS ??) into the XO-1 software images
  • Modification of Sugar Control Panel to set up the printer (add/select default printer?)
  • Modification of at least one activity (Write ?) to support printing
  • Making a printing activity, that follows sugar GUI guidelines?
I am highly interested in working on this project. Would the project leader mind contacting me at bmw.stx@gmail.com?

JavaScript-Python Communication

JavaScript Python Communication through the following strategies: PyXPCom, hulahop, and xulrunner. Ideally, develop a demo activity which could be used as a template for sugarizing javascript activities.

Graphical toolkit

Important work left to do:

  • Give focus feedback by showing a rounded rectangle in gtk buttons and HippoCanvas icons.
  • Implement keyboard navigation in HippoCanvas.
  • Implement accessibility hooks in HippoCanvas.
  • Improve keyboard shortcuts - make them easier to create and implement a UI to make them more discoverable, such as transparent letters which appear when you hold <ctrl>

Mono/.NET

The use of Mono could really enhance the number of Sugar developers due to the huge existing .NET community. Thanks to Torello Querci, developing a Sugar activity in Mono is already possible using the Mono/Sugar bindings Sugar.dll (more Mono here).

The idea for this GSOC project is to greatly enhance this binding:

  • Better integration with the Sugar look & feel and HippoCanvas,
  • Binding to telepathy API,
  • WinForm compatibility,
  • MonoDevelop integration.

Titanium Sugar

  • Integrate Titanium-made apps to Sugar.
  • Do a titanium activity to develop html/javascript/css appilcations inside Sugar.

Activities

VideoChat activity

telepathy-python has support for audio and video streaming and has recently gained support for using gstreamer, which means that we could easily do efficient videoconferencing using fully open source codecs.

So a really nice project would be to do a proper Sugar activity for video conferencing.

Language Trainer

A language trainer with text to speech support would be very nice. Something that could start with letters and then teach words.

Thesaurus

Working together with openthesaurus -- someone could create a thesaurus for kids to learn different words (synonyms and antonyms)

Improved Read activity

Use Gecko to implement a reader for epub format ebooks. This is superior to PDF because such books can be reflowed to better fit the screen and user preferences. Also, (although it would break the standard) it would make it very simple to include AJAX-style active features to books.

Extra credit if you support textual and graphical annotation. Deployments have also asked for a page-turn animation.

KDEEdu

Sugarize any KDEEdu activity, especially the ones which have no corresponding Sugar activity.

Gnash

Put some code around Gnash that allows to easily do activities based on Flash content. Also develop Gnash extensions that allow flash activities to interact with the journal, presence service, telepathy, etc

We need to add journal support (and a standard Sugar toolbar).
