Signing on the Web

We are hosting a meetup in our brand new office complete with a bar reception area to share what our engineers have learned and developed using HTML5.

We'll be providing plenty of beer and pizza so come hungry!

***Please bring your own laptops!

We'll highlight the functionality of our e-signatures by showing how we simulate the movement of a pen on paper with your cursor.

We sign our names onto various forms, receipts, and contracts on a daily basis. For some, signatures come off like chicken scratch, while for others they are like beautiful works of art. Regardless, each and every signature is as unique to us as are our finger prints or DNA, thus making them vital extensions of our identities.


Understanding the art, math, and science of signature creation can help reproduce this physical action in a virtual way. We will explore multiple methods of acquiring, beautifying, and applying signatures to a document using Javascript and new HTML5 technologies.

The schedule for our event will look like this:

6:00-6:30 Pizza and beer, laptop setup

6:30-6:35 A quick intro of Nitro by Tiho Bajic, VP of Engineering

6:35-6:40 Introduction to Signing on the Web

6:40-7:00 Image Processing Using Canvas

7:00-7:20 Simulating the Pen

7:20-7:30 Putting It All Together

 

By the end of the night, each participant will have created their own e-signature functionality and networked with other HTML5 developers and engineers.

 

Sound good? Well RSVP and come join us in our new office on February 27th!

    Adrian, you should check out sauvola and adaptive binarization. Much more robust techniques

    • Adrian O.

      Max, I completely agree with using some form of binarization algorithm. However, sauvola and adaptive algorithms were beyond the scope of the meetup. There is also a balance between performance, usability, and browser support that we have to achieve as developers.

      It would also be worth looking into writing pixel shaders to perform these algorthims - http://www.w3.org/TR/...­ (although support for filters is very limited)

      Cheers!

      Hi Christian, the Sutter Stockton Garage is going to be your best and least expensive bet (http://www.yelp.com/b...­). Please let me know if you have any questions.

    I'm a visual designer and dunno any HTML 5, would this be a good event for me? Thx.

    • Adrian O.

      Although I will be covering visual elements of creating signatures, this meetup will focus heavily on javascript and new HTML5 features. That being said, HTML5 and CSS3 have finally given artists a platform to create art that can be reached from any device without the use of any plugins.

      Check out http://www.html5rocks...­ and http://css-tricks.com...­ as they are great resources to get started. If you think you can get the basics by the 27th, by all means sign up!
