Smoothing Issues #2

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. jagged handwriting
2.
3.

What is the expected output? What do you see instead?
I need smooth handwriting like is achieved when using Smoothboard 2. I don't 
know if there is any way to adjust the smoothing setting, but when I use 
Smoothboard, my hand writing looks amazingly smooth.   When I use WiiTuio, my 
handwriting is way more jagged.  The students have a harder time reading it. I 
would just use Smoothboard all the time, but the Windows Touch events 
(MultiTouch) are a must have in my classroom.  I teach geography and BingMaps3d 
is amazing!  

What version of the product are you using? On what operating system?
Windows 7 Operating system.   WiiTuio latest version is the product

Please provide any additional information below.
If you could integrate smoothing into this app, it would be one amazing program.

Hi there :)

If you can get me some information on the smoothing algorithm used I can look 
at implementing it.  At the moment we use a running average, but I could swap 
it to be a Kalman filter or the like:
