New developments on Caribou

[David Pellicer <dpellicer warp es>]

 Hi to all.

 My name is David Pellicer and I'm an engineer at Warp Networks
 (www.warp.es).


 My company is working on a project along with the Consorcio "Fernando
de
 los Ríos" (www.consorciofernandodelosrios.es), a Spanish public
 institution, in order to make some improvements in the Caribou project.

 I am the person who is going to take over the project and I would like
to
 explain our objectives.

 I have been asked to develop the following features of the Caribou
 roadmap:
  * change the qwerty layout to have 4 rows instead of 3 (add more
 control characters to the first layer)(already included in Caribou)
  * improve text detection using atspi (already included in Caribou)
  * add sticky keys functionality
  * add support for word prediction using prediction dbus service
  * add 'alpha numeric sorted alphabetically' and 'alpha numeric sorted
 by frequency' keyboards
  * keyboard fully usable with 1 switch Autoscan
  * keyboard fully usable with 1 switch Userscan
  * UI for setting up switch
  * a mode that is always visible

 First of all I´m going to integrate the Joaquim Rocha's patch to use
 JSON keyboard [0] layouts instead of the actual specification. As this
 patch is based on a previous version of Caribou, then I will integrate
 the next set of  changes uploaded in the new way.
 For the prediction feature, I will create a D-Bus service using Presage
 [1], which is an interesting  library to make text prediction based on
the
 context instead of the characters of the word.
 If anyone is working on any of these features, please tell me on this
 list to avoid duplicated work, and discuss  the best option to
 implement it.

 Best regards.

 David Pellicer
