One Line Summary

A Chrome Extension that summarizes hour long lectures into snippets of important sections via crowdsourced time data.

Description

In my college, students revise the lessons for their exams by watching NPTEL Video Lectures. NPTEL is a repository of educational videos made by IITs, IISc and other premier universities. They are binge-watched by almost every student before their examinations in order to revise the entire course at once.These lectures are series of videos, each 50 minutes long with about 30 videos for every course. The one hour duration of each lesson isn't uniformly important. There is a long intro, an outro, portions where the professor gets distracted, there is irrelevant information and so on. NPTEL Condenser skips these parts for you and condenses each video into few minutes of most important content. I made NPTEL Condenser to solve this problem. NPTEL Condenser makes it easier for students to share their knowledge of important sections by marking the parts that are important. This makes the extension skip the un-important parts in all the users, thus compressing the time needed to revise.

The Launch Video

The extension has three modes to work with. Condenser Off turns the skipping functionality off. Condenser On skips any part marked unimportant by 2-3 students. Editing mode allows students to create their own custom timestamp data.

The three modes of the extension

Two buttons get added to the YouTube UI called 'Export' and a toggle button 'Saving/Ignoring'. Students can toggle the state depending on the relevance of the video being played.

A JSON file with the time slots to be skipped is generated that is auto sent to me which I update on subsequent versions.

The extension was loved by students and it received lot of appreciation. My friends suggested to automate the marking process using AI, which is a nice ambitious idea.

Automated Site Analysis by Method of Overlay | Link

I devised a numerical method to automate the (really boring) process of zoning a site for an architectural project by taking into account climatological and toplogical input from the architect.


Alumni Class Gift, IIT Kharagpur | Link

I designed a 15 feet tall structure dedicated to the Alumni Batch of 1972 of IIT Kharagpur. The designed evolved through a series of sketches and initial walkthrough renders.

ETH Zurich, Switzerland, May - Aug '15

I interned under Prof. Gerhard Schmitt at the Chair of Information Architecture. I implemented machine learning to create tools that enable architects to design spaces with greater control on the cognitive response of the user.

Based on my performance and enthusiasm, I was offered a research project at Bauhaus University, Weimar.

Witworks, Bangalore, Dec '15 - Jan '16

I was the Product Design intern at Witworks, a tech startup founded by alumni of my university in Bangalore. I worked on their second product called 'Blink', an IoT wearable that provide access to services on-the-go.

Through the branding campaign and media content, I helped increase the brand visibility and social media outreach to 16k Facebook followers.

Fablab CEPT, Ahmedabad, May - Aug '14

As a maker intern, I developed 'The Musical Facade', a dynamic screen that responds to music with motion. I did hands-on programming, electronic design, digitial fabrication to materialize my ideas into things.

I got accepted to the Smartgeometry 2014 based on my work at FabLab, being the youngest international delegate at the conference.

Smartgeometry 2016, Sweden, 4 - 9 Apr

I was selected in the '20,000 Blocks' Cluster headed by DU Darmstadt at Smartgeometry 2016. We worked on a gamified architectural platform to allow non-architects be an active part of the design process while having fun.

Smartgeometry 2014, Hong Kong, 14 - 19 Jul

In the 2014 edition, I was part of the 'Design Space Exploration' Cluster headed by ETH Zurich. We worked on devising algorithms that automated urban planning by taking subjective user input into consideration.

GES 2017 Hackathon

I was the Winner at Global Entrepreneurship Summit 2017 Hackathon organized by Gupshup. I built a Messenger chatbot that helped people find their missing items by pairing them with people in a 7 kilometer radius zone who have reported a found report to the bot matching their description. Source can be found here.

GE Edison Challenge 2016

My team 'Trafix' was the Finalist ( Top 10 in India ) in the GE Edison Challenge 2016. We built an app prototype that uses gamificiation to make following traffic rules fun. Trafix uses route planning algorithms on crowdsourced data to predict traffic congestion and plan individual trips in a way that optimizes the overall traffic.

Tata Social Entreprise Challenge 2016

I was the Quarter Finalist ( Top 40 in India ) at Tata Social Enterprise Challenge 2016 for 'Pullypal', a social initiative that focuses on generating employment through rural tourism. Pullypal offers a unique experience to travelers who wish for a more immersive cultural and social experience in their travel.

Inspiring Minds, IIT Kharagpur

[ FILM MAKING | PHOTOGRAPHY ]

I make movies about things that strike a chord with me. 'Sweeten' is both about nothing and many things at once. I made it on my visit to Sweden, and hence the pun. 'Melancholic Times' is shot in the ancient city 'Hampi'; it captures moments of contrasting inner peace and turmoil. I also make not-so-serious videos, mostly Indian college-centric ones under the banner of 'Spectecool' (34k+ views). While at it, you may also like to see me being kicked out of my comfort zone performing stand up comedy over here. I click pictures of pretty places here.

I pen down my thoughts on issues I care about on Medium and answer questions that I think will be of use to others on Quora. Some articles that I like are: The Open Cage: Modern Day Slavery and Religion 2.0.

My article on consumer behavior titled 'The Irrational Consumer' was published in Economica, the publication on economics and public policy by Economics Club, IIT Delhi.

Questions I've answered about architecture: What are the most well architected buildings in the world?, , What career paths combine computer science and architecture?, What is the difference between a 'space' and a 'place' in architecture?

and some general ones: Why is money not the most important thing in life?, What is a paradigm shift?, Why are some languages written with straight lines while others with curved lines?, How can I visualize 4D shapes in my mind?

[ SOCIAL CAUSE ]

I am part of the LGBTQ support group in my campus called 'Ambar' which is trying to sensitize the student community about gender diversity and make the campus a better place for all students irrespective of their orientation.

I am also the Winner of the National Level Debate at Spring Fest 2015 that had 300+ participants. I was the Director of Communications at Model United Nations too in 2013.

[ LEADERSHIP ]

As the Executive Editor of The Scholars' Avenue, the campus newsbody of IIT Kharagpur, I am responsible to launch new projects and ensure their execution. I mostly take up creative assignments such as 'The Happiness Project', 'The Marauder's Map', 'The KGP Society Periodic Table', 'KGP: Year in Review' and such. Under my leadership, the media body has seen a rise in the Facebook followers to 36k+ and monthly readership to 10k+

[ !ARCHITECTURE? ]

I have a love-hate relationship with Architecture. To me, Architecture is a field which in its essence is as surreal as poetry or music but has been reduced to the stature of make-up for real estate. I think Architecture is more about the soul and the mind than about buildings. I do not inted to pursue the field in the way it is practiced, but I do value the impact of the architectural design process in all of my works. For my undergrad thesis (to be completed by July 2017), I am designing the 'Centre for Emotional Technology and Artificial Intelligence' that shall embody everything I have learnt and wish to give back to architecture.

Thank you for your time. You can find my resume here.
