Enhanced Orca

1)Enhancements to screen reader Orca: CDAC team has contributed following features to Orca screen reader of GNOME desktop:

  • List Shortcuts: This helps a new Orca user who finds it difficult to remember the numerous keyboard shortcuts. At the press of a key combination, Orca is ready to speak the list of available shortcuts. The user can navigate the list with Up/ Down arrows. This has become a standard feature for GNOME 2.32 and later. More information can be found at https://bugzilla.gnome.org/show_bug.cgi?id=616820
  • Skim Reading: While reading a large document, a user may want a quick preview of the contents or he may want to go directly to a specific paragraph. In Skim Read, Orca skims through the entire document, reading only the first line/sentence of each paragraph. The user can halt at the desired paragraph by pressing the CTRL key. The feature has been tested by members of Orca community and may become part of a future release. More information can be found at https://bugzilla.gnome.org/show_bug.cgi?id=577481
  • Structural Navigation for OpenOffice.org: Structural navigation enables a user to navigate through elements of a specific category like tables, headings, etc. by pressing only a key or two. For example, a user can move to the next heading by pressing H and to the previous heading by pressing Shift+H. In Orca this feature is available for HTML documents, but not for word documents. CDAC team
    studied the accessibility of OpenOffice.org and identified bugs which were blocking implementation of structural navigation. CDAC team has also submitted patches to add structural navigation to word documents. More information can be found at https://bugzilla.gnome.org/show_bug.cgi?id=652105
  • Navigation by sentence : This feature provides navigation by sentence in Libre/Open Office Word
    Processor documents and text documents. To read the current sentence, press Windows+slash. To read the previous sentence, press Windows+comma. To read the next sentence, press Windows+period. More information can be found at https:// bugzilla.gnome.org/show_bug.cgi?id=520591
  • Restoration of NumPad functionality : Flat Review takes over NumPad functionality even when NumLock is on. This problem was fixed for the main Orca branch w.e.f. Orca v3.3.4 but
    not for xdesktop branch. CDAC Mumbai has fixed the problem for orca-3.2.0-xdesktop. So NumPad keys can be used to type numerals and arithmetic operators when NumLock is On. Additionally, NumLock On/ Off announcements and key echos for Super key and Menu key are enabled. More

Enhanced version of Orca-3.2.0-xdesktop which includes the above features can be downloaded from HERE.

2) Making PDF documents accessible: CDAC Mumbai made PDF documents more accessible and usable for blind users through Orca. This method of accessing PDF has been listed on ORCA Wiki. More information can be found at "http://live.gnome.org/Orca/Acroread#Use_pdftohtml"

PDF to HTML utility script can be download from HERE.

3) Easy traversal of desktop icon and modified search facility: Desktop is the very first screen after logging into the system. A visually impaired user may need to know what is available on the desktop by traversing it once. In absence of visual feedback, it is very confusing for visually impaired to exactly know the state of desktop. This feature helps user traverse the desktop icons completely by using a single arrow key (Down arrow key). More information can be found at https://bugzilla.gnome.org/show_bug.cgi?id=613111

Search facility has been modified on Desktop icon view also.
