Thank You!


Microsoft Lab

Set up in end-2001 with a grant from Microsoft Goals

Create Windows infrastructure in the department

Promote the use of Microsoft technologies in student projects and faculty research

Initiate collaborative research with MS Over 50 projects so far


Communication Empowerment Lab Focus on developing technologies for

Augmentative and assistive communication (AAC) devices for people with disabilities

User-adaptive communication and information technologies for the common man

Focus on vernacular and multilingual communication, social realities and culture

Funded by Media Lab Asia and other government agencies


Telemedicine Systems

Telemedik – telemedicine system over low-bandwidth links Aim – provide medical expertise from city

hospitals to remote hospitals with inadequate expertise and infrastructure

Fully operational system with all advanced features of a telemedicine system, developed in Telemedicine Lab

Installed at 6 hospitals, being installed at 12 others in eastern and north-eastern India


Mobile Telemedicine Telemedicine application on PDAs/Cellphones

for doctors on the move Integration of text and image transmission

over wireless links Display and processing of medical images on

PDA – challenges posed by small display area, limited computational power and memory, power constraints



Intrusion Resilient Database

Aim to create a database capable of restoring its

consistency even after being compromised Based on compensating actions and re-

executions as in other schemes New transaction dependencies proposed and

evaluated that improves on existing schemes Prototype system built around SQL Server 2000 Part of a multi-year project funded by Govt. of

India on building resilient systems


Sanyog (“Connection”)

An alternative communication aid for people with speech impairment and neuro-motor disorders

Visual, iconic language based, speech enabled Can be personalized to the cognitive ability of

the user Alternative access mechanisms with scanning

and access switches


Their manner of speaking


Some Snapshots




Access Mechanism


Supports 3 languages – Bengali, Hindi, and English

The system has been deployed at four centers in India Indian Institute of Cerebral Palsy, Kolkata Action for Ability Development and

Inclusion, New Delhi Monovikas Kendra, Kolkata Blind Peoples Association, Ahmedabad

Winner of Da Vinci Award – Engineering Society of Detroit & Multiple Sclerosis Society, Michigan chapter


Samvidha

Providing low cost internet access from rural schools Rural schools have only noisy phone lines Most cannot afford the cost of long connections

Offline access Student queries packed by local server in school

and sent in email to central server Central server browses web to get results,

packages pages and sends to local server. Can be accessed anytime after that



Features

Ontology based filtering of web contents Only relevant documents shown

User modeling for personalized retrieval User profiles learnt from browsing patterns,

and/or from user inputs Ontology guided navigation and search from

the locally built repository of contents Reduces access time if locally available

Vernacular based search interface Pilot deployment at 4 schools so far


Online Transcoding of Web Pages for PDAs

Small display area is a problem Proxy-based re-authoring of web pages Presents only “relevant” information

categorized under predefined domain specific categories

Unique visual-cue and page structure based algorithm to fragment a page into related blocks

Categorization using rule-based system
