8. VET – INDIA
STEP CHILD OF EDUCATION
Annual Incremental workforce:
12 MILLION
Annual Training capacity:
3 MILLION
NUMBERS TO BE TRAINED BY 2020 :
550 MILLION
(~191,000 people/day)

9. Vocational Education is essential in the empowerment of underserved
populations. Vocational Education in India is outdated and
disorganized.
Outdated practices/
technologies
Cost of courses
Lack of good
education
infrastructure/policies
Quality training
inaccessible
Social stigma
Illiteracy
Lack of Trainers

11. Design Challenge
➺Large Numbers (~500 million)
➺Dispersed locations (take training to the people not
vice versa)
➺Minimize need for new infrastructure
➺Greater accessibility
➺Standardization of course content
➺Scalability
➺Cost effective
➺Adaptability to local environment, language, dialect
➺Low or non-existent literacy levels
➺Incentive to learn

15. Haptics in Training
Surgery, Driving Simulator, Flight simulators

16. Why and where Haptics?
Cost
• Materials used are expensive
• Tools used are expensive
The tools/ materials are hard to
transport/ store
Skilled teachers are hard to find
Task involves skill developed over a
long period of time
Safety is a significant concern
AMRITA VISHWA VIDYAPEETHAM

17. Haptic device design challenge
Keeping haptics cost effective :
high forces and large workspaces
make device design complicated
and hence expensive.
AMRITA VISHWA VIDYAPEETHAM

18. • Need of Expert
• Safety measures
• Cost of Tool
• Portability
• Technique intensive, Skill intensive
Tool Selection
Criteria for
Haptic
simulation
• Type of Grasp: Contact, Precision, Power
• Workspace
• Degrees of Freedom – x,y,z (translation, roll)
• Degrees of Force feedback – x,y,z
(translation, roll)
• Posture while working
• Powered or Non Powered Tool
