Anyone know of a piece of software that can be used for hand written input on a laptop or desktop?

I use Sogou on my tablet and phone for writing characters by hand, but it doesn't seem to be an option for me on the laptop. I'd quite like to be able to do as much as possible with hand written characters on the computer and would love to know about any software available that can extend my practice in this way.

Go down the electronics market and get a handwriting pad for 20rmb. Or if you are on win7, google and download vistalizator with chinese language packs.

For adding Chinese Handwritten input to Windows 7, try this page for some help:

This site is mainly for getting pinyin to work on Windows, but does cover handwriting to some extent.
If you have Windows 7 English version installed, you have English handwriting recognition, but you need the Enterprise or Ultimate to add Chinese handwriting recognition. If you have a Chinese version of Windows 7, I believe you already have Chinese handwriting recognition.

Pinyin and single character input are already available on Windows, but you may have to set this up. It's part of the IME.

At any rate, This is my understanding of the handwriting recognition situation in Windows.

Thanks for both the responses. Took me a while to reply as I've been on a train from Kunming to Shanghai over the holiday weekend.
I'm definitely going to check out these options though and see what works best.
Appreciated.

Sougou's IME will do it in Windows too.

Once it's installed, type something in and you should see something like 手写输入, click that and it will install the plugin required. Then type something in and you should see 工具箱, click that and you will see 手写 as an option.

You can set up a keyboard shortcut for this, to open the tool box while typing the shortcut is ; (分号), and then X for handwriting, or you can set one up in the options (Ctrl+Shift+M, P for properties (属性), then 按键 then 扩展功能快捷键 select something like Ctrl+Shift+W.

It seems to work pretty well in my testing, and in general the Sougou IME has lots of cool little features, although finding them is probably easiest if you can read their website in Chinese.

You might also want to look at the stuff NJStar has produced. They have a handwriting recognition software among other things related to text. They offer demos, too.

太棒了，用手写现在多方便了！其实另外一些软件也挺好我终于选了用搜狗因为对我来说好像是最简单的。感谢你们！

yea sogou and baidu 输入法 are the most popular in China I think
