My pleasure! I love trying out stuff like this, especially in these days of trying to whiteboard remotely. As it is getting late, I may just make this a brief test right now.

A minor point to note is that the URL with the www does not work - you may want to fix this:

https://www.browserboard.com

Also I love this bit of humbleness:

So on to the handwriting test. Yes! You are much closer to the Ziteboard experience. Pen input works very well on both the ThinkPad Yoga and the Note 8 and it renders my writing nicely.

You seem to be doing a similar kind of smoothing that Ziteboard does? When I write on Ziteboard I see a bit of angularity as I write, which gets smoothed out when I'm done. Yours seems to do this more in real time.

One thing I got confused on: trying it on the Note 8, I wanted to scroll the view to get some blank space to write on. I found the four headed arrow icon which did exactly what I wanted - I can now scroll the view with the pen or finger. But now I can't figure out how to get out of this mode and write again?

More later as I experiment with it...

The pan feature works like a "tool", so you can select any tool (pen, text, etc) to get back to drawing.

Touch interactions are definitely a work in progress, I just want to make sure they aren't broken for now. :-)

I'm doing fancy incremental line smoothing. It's not that hard, but no one else seems to do this, and it really bugs me. It takes some effort to understand how and make it performant, but it's such a nice boost to the feel of it, in my opinion.

Yeah, that incremental line smoothing makes such a difference. Ziteboard is pretty good and I have no complaints about it - my writing seems a bit angular in realtime, but seeing that almost-immediate smoothing makes me think "Yeah, that's exactly what I meant to write."

But you do it immediately as I go!

I noticed a little bug on the Note 8 - when I'm on the main page where I can sign up or create a board, it's chopped off on the left and right sides. Selecting "Desktop site" from the Chrome menu fixes it.

Tested on my Dell Latitude 5290 2-in-1 (AKA. my sidearm), with Dell's active pen, running Firefox.

Works surprisingly well, it's the first web whiteboard that's actually usable with the pen. Congratulations on getting this right! One minor inconvenience: when I draw with the pen, it doesn't show the line I'm drawing until I lift the pen back.

I think you found a bug! I didn't build any special support for pens, and it sounds like something's wrong here.

late to this thread, but I noticed the same behavior on Firefox (81.0.1) without a stylus/pen. whatever tool is the default when creating a new board, when I started writing nothing showed up until I stopped clicking.

I like it.

Its a little awkward that the line doesn't draw when your cursor / finger is held down, and only on release. Other than that, great. I had no dramas getting out of pan mode.

Tried it with my iPad Pro and Apple Pencil, and it worked great. Well done!
