The simplistic interface mainly consists of three boxes (panels): the data box in the center, the coordinate box on the right, and the message box on the left. Data points can be generated by clicking on the data box. The coordinates of the generated data points will appear in the coordinate box. The bottom buttons ("Auto", "Manual" and "Virtual") are for the purpose of reference selection.

Procedure 1: data Input

You may simply click on the data box to generate data points. You may also cut and paste your existing 2-dimensional data into the coordinate box and then click the "Plot" button.

Procedure 2: reference selection

You may choose either of the three modes for reference selection. "Auto" automatically generates a specified number of references in a random fashion. By default, this number is n, meaning all data points are selected. "Manual" allows you to name the references by specifying their indices (e.g., 0 9). Indices start with 0. In the "Virtual" mode, you may click on the data box to generate virtual references. The virtual references will disappear once you switch to another mode.

Procedure 3: bisection clustering

You may click the "Corbis" button to cluster the input data points. The produced clusters will appear in different colors. The selected references will be circled. The cluster labels will also be shown in the coordinate box for the data points. A special label v is reserved for the virtual references. A simple summary including running time will be shown in the message box.
