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

11

• 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

14
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

Access Mechanism
20

• 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

21
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

24
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
