Anumaan gives predictions based on preceding text/words used by the user in his/her text and user can use these predictions, while composing text. By incorporating predictions, user can improve his/her rate of text entry to a great extent.
Anumaan is mainly intended to help persons with motor disabilities, specially ones facing problems in hand and finger movement. Such persons face difficulty in using regular input devices like keyboard for text entry related tasks. Anumaan can help such persons immensely in their text entry related tasks by way of predictions. However, It is equally useful for common users also and can support them in creating mails, letters, documents etc. in less time.
Salient features of current version include:
More user-friendly and simplified interface for easy interaction and navigation.
Re-oriented layout of text entry area and prediction display in order to reduce visual and cognitive overhead.
A single comprehensive prediction list combining predictions from all relevant grams for easy selection.
Keyboard support for selecting predictions from prediction list. It reduces time taken in selecting and committing predictions to text.

CDAC, Mumbai has released beta-0.1 version of GEM (GEstures with Mouse). It is an open source input mechanism which uses gestures as input to the system. Gestures can be drawn using a mouse or some equivalent device like touch pad, joystick, pen tablet etc. Gestures can drawn either as single-part (continuous) or multi-part (discontinuous) as shown in screen shots below:
This Input mechanism is intended for people suffering with different kinds of motor disabilities, who may face problems in using mouse and keyboard in conventional way. Hence, it provides them with an alternate and effective mechanism for using the system to perform various tasks such as navigation, executing commands & keyboard shortcuts, and launching applications etc. on Linux desktop.
Today Anumaan (alpha-0.1 version) has been released by C-DAC, Mumbai as a part of its activities and commitment in the area of accessibility. Anumaan is a perspective-based, on-screen predictive text entry system for GNOME desktop. 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 for UTF-8 unicode encoding. The system allows users to train it and personalize and as per their writing style into different named domains. 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.
