About

Pick a sheet of paper, grab a pen(don't bother uncapping it) , turn on your webcam and voila you are good to go. CleanSlate is a novel way to write notes. It uses cutting edge computer vision to observe what you trace out on a piece of paper and displays it on your computer screen. Our solution is not only simple and inexpensive but also very easy and seamless to use. Check out its demo at - https://youtu.be/uKlZ2o-pgIw https://photos.app.goo.gl/jbpnWiaJPsWBfyLK9

We perhaps feel we did a poor job in presenting our product.

Rohan Rajpal - 1191d

Thanks a lot to everyone taking out time to give feedback here! We learned a lot and hope to learn more in future :)

Rohan Rajpal - 1191d

A few questions that our mentors asked Why not just use a camera? A camera won't be able to arrange the text into slides like done in a digital slate. Plus in the future, we aim to convert these annotations into digital text in real time. Why not just use a simple OCR then instead of this product? Since we will be tracking the handwriting word by word in order. We'll have much more data and much more accuracy in detecting digital text.

Has been solved, also with smartphones everywhere, a desktop/tablet oriented solution has little mileage in 2020.

Rohan Rajpal - 1191d

We did some research and could not find any such product in the market. It would be great if you could point out to us who has done it already.

Rohan Rajpal - 1191d

Sir when lectures are given to around 100 and above students. Professors use digital tablets to write on so that the handwriting can be projected on big screens.

Rohan Rajpal - 1191d

A professor, however, can't write on a phone and they need big screens and tablets to write on. Any phone's screen cannot replace them, but our idea can with a phone's camera, any pen and a sheet of paper!

Kiran Chhabra - 1192d

do think about the idea more

Rohan Rajpal - 1191d

Yes ma'am we will. We believe that the logical next step will be to generate digital text in real time along with the current annotations

Prerit Gautam - 1192d

Not unique. No business model.

Rohan Rajpal - 1191d

Please refer to our comment above for Uniqueness and do let us know if you find any such product!

Rohan Rajpal - 1191d

As we mentioned in out pitch, we aim to target all educational institutions. This idea, In its current stage, has the potential to replace expensive tablets that annotate handwriting on slides.

Niyam Bhushan - 1192d

This has been done hundreds of time since 10 years. not original at all. Portronics already sells a device. A company in the US sells this for a long time targetting students in the US. Nothing new here at all.

Rohan Rajpal - 1191d

Sir ours is a software solution, you can use any pen, paper and camera to make this work.

Rohan Rajpal - 1191d

We had a look at portronic ruffpad. It's a tablet in itself. All other are hardware products. We achieve the same with the video captured from any camera.

Rohan Rajpal - 1191d

If still you know a product exactly same as ours, do let us know.

Bibin - 1192d

Cant see a mass adoption of the product. Not an original idea. Not a pain problem to solve.

Rohan Rajpal - 1191d

Sir any educational institution would be willing to buy a cheaper alternative to buying an expensive digital tablet for each class. This idea just needs a camera, pen and paper. Even a phones camera will do.

Rohan Rajpal - 1191d

For the originality, please see our reply to Arnav sir's comment.

Rohan Rajpal - 1191d

We as students find new professors always struggling to work on digital tablets, since each company has their own software and setting up to project the tablet on screen.

Rohan Rajpal - 1191d

So the professors end up calling the IT guy who then sets up stuff.

Rohan Rajpal - 1191d

Whereas writing on a piece of paper is natural to anyone, our software tracks your writing and converts it to digital annotations.

Sairee Chahal - 1192d

Poor identification of the problem. The idea needs more research.

Rohan Rajpal - 1191d

Ma'am please read our answer to Bibin sir's comment.

Harsha Kakkeri - 1192d

Implication will be tough! Stylus I recommend. Good luck
