  • (30 secs) One line intro to self - Hello, I am Bhavani Bijlani and I head AMMACHI Labs, the Human computer interaction and learning technologies lab at Amrita University.
  • (30 secs) One line intro to Amrita University - Amrita University is dynamic 5 campus multi-disciplinary campus university spread over 3 states of south India with over 14 schools and 150 degree programs, 2000 faculty and 17000 students.
  • (30 secs) One Line Introduction to AMMACHI Labs - AMMACHI labs is nestled right next to the ocean in the lush green of southern Kerala. At ammachi labs our main focus is on developing applications using technology for skill development ranging from vocational training to medical rehabilitation to serious games.
  • (2 Mins) Intro to different projects at AMMACHI Labs, their objectives and their funding sources - SAVE, WE, MOVE.
  • (3 Mins) The Design Challenge : SAVE's target population-computer illiterate, poor, ridden with social stigma - hence solution has to be easily scalable, cost effective, intuitive to use, self paced etc...
  • (4 Mins) SAVE VET solution - software application + Haptics . Software contains - video lectures, games etc... (can use ajay's PRSG and old SAVE slides)
  • (2 Mins) Haptics -Specific Challenge - high forces and workspaces make device design complicated and hence expensive. Hence had to break up tools in to categories, and focus on training skills. Identifying the most critical skills that are required for motor skill learning subjective to the use of tools is a challenge ( only training what is most essential, thus simplifying design of device and lowering costs)
  • (4 Mins) The solution for Haptics:Show slides on haptics - tool characterization parameter slide, then show solution, the devices, screenshots of visual interfaces
  • (2 Mins) Skill Analytics:Explain the Graphs of novice vs experts in use of hacksaw
  • (2 Mins) Show deployment pictures and Statistics of data from feedback (srividya's slides)

    8. 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. 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 Vocational Education in India is outdated and disorganized. Outdated practices/ technologies Cost of courses Lack of good education infrastructure/policies Quality training inaccessible Social stigma Illiteracy Lack of Trainers AMRITA VISHWA VIDYAPEETHAM

    11. 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 AMRITA VISHWA VIDYAPEETHAM
    12. 12. Multimodal approach S.A.V.E. Multimedia • Video Lectures • 2D/3D simulated labs Haptics • Smart tools • Low cost Haptic Devices • Skill Database Immersive Environments • Virtual Reality • Augmented Reality E-learning • Integrate with Aview • Mobile Classrooms
