The purpose of this research is to expand the choices of menus that can be used with note-taking applications and to propose practical palm rejection algorithm. This research proposes three approaches to achieve the purpose and to make closer to smooth note taking. The first approach is reconsideration of menu design. From the view point of note- taking, general linear menus on note-taking applications have drawbacks, one of which is the difficulty of rapid manipulation without occupying the writing space. To solve this issue, we developed an arc-shaped menu and compared the menu to general linear menus that were located on the left of the screen edge. As a result, the manipulation speed of our menu was faster than that of one of the linear menus that popped up on the left of the screen edge. In the second approach, we propose a palm rejection algorithm. Some existing palm rejection algorithms accidentally remove correct ink strokes. To reduce the frequency of removing correct ink strokes, we developed a palm rejection algorithm and, conducted an experiment that found that our algorithm had fewer occurrences of removing correctly drawn strokes than other applications. The last approach is, developing a menu invocation method. After conducting an experiment with regard to menu design, we noticed that menu invocation methods and invocation positions also have influence on smooth note-taking. In order to propose a novel menu invocation method, we applied our palm rejection algorithm to invoke context menus. Our invocation method invokes a context menu when the user lifts the writing hand from the screen. Then, we compared our invocation method with other invocation methods used in past research and existing applications, and evaluated which menu invocation methods are manipulated rapidly and where menus should appear. The results showed that when the menu position was set at the left edge of the screen, our menu invocation method was significantly faster than the bezel swipe and long press.
