Abstract This paper proposes a method of rotating a three‐dimensional image on a screen by using a two‐dimensional pointer (e.g., a mouse cursor) to make medical diagnoses easier. The apparatus rotates the three‐dimensional image by directly clicking and dragging areas of interest with a pointer so that a user (e.g., a busy doctor) can examine the image from any number of angles without a break in his/her concentration. Experiments show that the proposed method is faster by 20 percent and simpler and easier to use without special training as compared with a conventional method (in which a mouse cursor points in a numerical viewing angle direction).
