Abstract
Smart phones are capable of many things computers can do. However, smart phones have comparatively less resources. For example, touch screens have been considered a limited form of input compared to mice and keyboards, for touch screens are limited in the number of keys and the screen size. As touch devices get smaller, users have to perform many clicks to access a function due to the screen size and lack of input modality. In this paper, Lift Menu is proposed as a solution to fast input on a small screen by extending the input space from the 2D screen to the 3D space above. The space is segmented into different layers with each containing a pie menu to allow for more capacity. A user lifts his finger from the screen to access the menus and moves the finger in the air to navigate through them. We conducted a series of user studies to explore the design parameters of Lift Menu and to compare its performance with the touch interface. Both the quantitative and the qualitative results prove the feasibility of Lift Menu and its efficiency on a small screen.
