CountMarks: Multi-finger Marking Menus for Mobile Interaction with Head-Mounted Displays

摘要

We designed, implemented, and evaluated CountMarks, a novel menu that extends marking menus with multi-touch input on a secondary touchscreen, for use with smart glasses and head-mounted displays. We experimentally compared CountMarks to marking menus. Results indicate that CountMarks offers faster selection and better search accuracy, but slightly worse selection accuracy. A second experiment compared standing vs. walking while using CountMarks, and handheld vs. on-leg interaction. Results indicate that CountMarks can be used effectively with a handheld device while both standing and walking. We present an example application employing CountMarks in a mock Netflix UI, to demonstrate how the technique can be applied in existing applications.
