As 3D user interfaces become more popular, quick and reliable aerial selection and manipulation are desired. We evaluated a virtual curved interactive surface with controllable curvature based on raycasting. The user operates the surface by pointing using a head-mounted display and grip-type controller. We investigated the operation speed and accuracy of curved interactive surfaces under various presentation conditions. To investigate the users' operation ability for different curved conditions, we experimented with multiple surface curvature radii, including completely flat conditions. The experimental results showed that varying the curvature of the display improved the pointing accuracy by 28% and the speed by 15% over the flat surface in the most effective cases. These findings can be applied to curved interactive surfaces with mid-air pointing for 2D-style applications such as GIS and photo browsers.
