Anumaan (alpha-0.1version) has been released by C-DAC, Mumbai as a part of its activitiesand commitment in the area of accessibility. Anumaan is aperspective-based, on-screen predictive text entry system for GNOMEdesktop. Basically, it is an extension of an Input Method (IM)mechanism (on GNOME desktop) in the sense that it extends its (IM)notion by including the power of text prediction. It has support forUTF-8 unicode encoding. The system allows users to train it andpersonalize and as per their writing style into different nameddomains. Hence, it adapts to user's writing style in some sense.Although, the current version does not support live mode adaptation,still a user can train a domain as many times he likes.

Anumaanis designed for a (text) sequence prediction based on a certainContext.The context can either be a partial word context or a partialsentence context. Therefore, it is intended to help people sufferingfrom different kinds of motor disability by allowing it to becustomized for different kinds of Input devices (e.g. keyboard, mouse,joystick or any other pointing device especially built for peoplesuffering from motor disability). In other words, it can be customizedvery easily to cater to different hand movement capabilities. Thecurrent version is only for mouse and keyboard based interactions. But,we can easily customize it for different hardware input devicerequirements.
The current released versions have two flavours:
1. Anumaan-standalone: The base system which runs on Java Swing Interface.
2. AnumaanLinux:The Linux version which uses Anumaan-standalone as base and is portedto utilize the accessibility features of GNOME GAIL library. Thecurrent interface is accessible to almost all Gtk+ Editable TextWidgets.
