However, a variety of functions induce great complexity to the interface operation so that users require much cognitive effort in searching the target menu item. Many research proposed evaluated methods. Pie menus are purposed for improving usability. However, no previous research studied the influence of the item length, boldface and human’s physical characteristics of visual search (Shneiderman, 1988; Feng & Shen, 2006; Moyle, 2001) and mouse movement (Moyle, 2001; Donker & Reitsma, 2005; Whisenand et al., 1999). This study examined these factors and proposed Elliptic-Pie Menu and then conducted experiments. The study revealed: (1) Menu type was a significant factor of the operation efficiency; (2) Linear Menu presented the highest efficient dominated by users’ operation experiences, whereas Circular-Pie Menu had the lowest error rate; (3) Boldface first letter increased efficiency; (4) Elliptic-Pie Menu has significant improvement of efficiency with the assistant of short items especially with boldface first letter; (5) Visual search was the major cause of cognitive effort.
