A new type of elliptic-pie pop-up menu was designed with ergonomics benefit assumptions. Its operation efficiency was tested together with conventional linear and circular-pie menus in terms of response time and error rate according to different lengths of menu items. A Q score afterwards was proposed for evaluating overall efficiency quality.
