Circular layout of radio buttons to a Web page using Perl
Sometimes it is necessary to layout radio buttons freely on a Web page. I once performed an experiment, in which I asked the human subjects to answer the sound direction and distance after hearing a spatialized sound. For this purpose, I used a Web page that contained radio buttons. The subjects answered by clicking one of the buttons. This method enables free layout of buttons, e.g., circular or any other layout, but the layout must be decided carefully not to overlay them with other contents. So, when it is possible to layout the buttons in an easier method, for example by a table, this method should not be used.
