Sanyog :

The aim of the project Sanyog is to develop a vernacular Augmentative and Alternate(AAC) system for the people with severe speech and neuro-motor disorders. This segment of the population can not use the keyboard and the mouse, thus being alienated from normal computer usage. This factor, coupled with their speech impairment impedes their communication.

Presently Sanyog supports three languages, e.g., Bengali, Hindi and English. In each language, there are three communication modes. These are,

   Iconic mode

   Alpha-numeric mode and

   Stored message mode

In the iconic mode, a user can construct simple sentences by the selection of icons and can have them spoken out using a text to speech(TTS) system. It supports generation of simple sentences for different tense, aspect and modality from the same sequence of icons. This mode also produces an iconic form for the sentence formed. The iconic communication mode is primarily aimed at people with low language skills.

Iconic Communication Interface

However, for advanced users, the system provides the alphanumeric mode of communication. In this mode, the user can construct complex messages with the help of an on-screen soft alphanumeric keyboard with standard editing facilities. Moreover, the keyboard is supported by word prediction techniques and is speech enabled.

The selection of icons or the keys in the virtual keyboard can be achieved using special access mechanism, that includes auto-scan and special selection switches to alleviate the use of mouse and keyboard.

In the stored message mode, a set of pre-stored messages is kept in the system. Each of these messages is accompanied by one/more images. The interface component shows these messages to the user and the user communicates by selecting one/more of these messages. This mode is also speech enabled.

  Embedded Sanyog :

The desktop version of Sanyog cannot be wheelchair mounted. PC cost beyond affordability for most SSMI affected users. Target users require low cost device independent of wires, external switches and on battery backup.

    In response, tablet versions of Sanyog are developed on Win-CE and Linux platforms.

 

ARM-Linux based version

 

Win-CE based version

  Sweepsticks :

SweepSticks is an adaptive user interface for a special community of users who have severe neuro-motor impairments mainly caused by cerebral palsy. In particular, it is a virtual mouse to be used by this population of users since they do not have sufficient motor control to use a normal mouse. It is equipped with methods of scanning the desktop interface of the computer where two “sticks” sweep the screen. The user, through some special switches can control the sweep and thereby reach form every part of the screen to every other part. A prediction scheme has been incorporated into Sweepsticks which predicts action to minimize the overall navigation effort. The Sweepsticks adapt to the user’s preference.

  Aakash Bani :

A Voice Output Communication Aid (VOCA), Aakash Bani, is an electrical device that assists people who are unable to use natural speech to express their needs and exchange information with other people during a conversation. The VOCAs store pre-recorded messages, which are produced in the form of digitized speech when the user presses an image. The most elaborate VOCAs include software that allows users to create and combine words to produce novel utterances in the form of computerized synthetic speech. SNLTR has recently developed a VOCA system for people with autism. This would definitely enable autistic persons to use tablets running on Android platform seamlessly.

Versions: The first edition of Aakash-Bani, so named as it is being launched with Aakash tablets, will have three versions to challenge various levels of disability. These applications should help persons with disability communicate better with those around them.

  Touch Mode: A person can select a desired icon simply by touch. The popular touch screen phenomenon is used here.

  Auto Scan mode: This has the touch facility through the auto-scan feature. This means that the user can touch any part of the screen and the highlighted icon will get selected.

  Switch Mode: This version allows the user to communicate with two bright red switches. “By pressing the first switch, an icon gets selected (for instance, two girls crossing a road) and on pressing the second one its message (be careful while crossing) becomes audible.

 

Auto Scan Mode

Key Features:

  Can be customized as per the needs of the user.

  No. of grids may be increased or decreased.

  Grids can be modified, changed, edited.

  Provision for sound recording in .mp3 format.

  Special access switch :

All the above systems mentioned above are supported by Special Access Mechanism, which is required to make the systems usable by severely disabled persons. The mechanism consists of two components, namely the software component called scanning and the hardware component called the access switches. The scanning mechanism scans the items in the iconic interface sequentially in such a way that the icon selection effort is minimized. In access switch mechanism different special access switches, such as palm switch, foot switch and leap switches, are used by which the disabled users can use the system with less effort.

  Entertainment and Social Interaction :

We have developed a toolset that will allow people with severe spastic cerebral palsy (CP) and highly restricted motor movement skills to access Education, Entertainment, popular social-networking and communication mediums like, Reading E-Books, watching/listening movies/songs, Facebook and E-mails. To understand the requirements of the intended users we have performed a number of surveys that acted as basis of our system design. The developed tools use special access switch based scanning technique for easy navigation in different applications.

  Web Browser :

An open source light weight web browser that allows easy dissemination of information through World Wide Web for people with motor impairment. The browser is augmented with both automatic as well as manual scanning mechanisms through which a motor disorder person can access its GUI. Further, the browser pro-vides an intelligent content scanning mechanism through which the web contents can be accessed with less time and cognitive effort. Along with the desktop version, the browser is also successfully ported on Aakash tablets that make the system portable.
