Basically what’s a virtual keyboard is that its simply an input without a physcial keyboard.
If you add this as a Keyboard Bookmarklet (Firefox recommended – drag this to your toolbar), you may use this keyboard on various websites buy clicking on your bookmark which launch as translucent, mac like, on screen keyboard.
However, you can use this keyboard to enter text into textareas and input field by using your mouse, stylus or touchscreen. If you decide to use your physical keyboard, the virtual keyboard gets “lighted up”.
Some have asked me the purpose of this project anyway. Some sites like this would say there’s enhanced security particular from keyloggers. Of course, this isn’t really true since virtual keyboards may be backdoors themselves so please do not use this or any other bookmarklet, greasemonkey, addons etc you do not trust for sensitive information.
Yes, one reason is that I’m having playing around with html canvas again. Another is that I have always been interested to with multiple inputs/users. Creating custom interfaces with canvas could create the possibility of interfacing 2 users in a browser – imagine 2 users surfing the net together by sharing a wide browser screen on a pc. Fifa 95 (thats over a decade ago!) allowed 2 users to play with or against each other – one with the keyboard, another with the mouse, and this would be possible with a virtual keyboard (for the 2nd user). Whether this is another lame project, or whether there are possible great ideas, I’ll leave it up to your imagination.
