Abstract:
Compared to traditional flat displays, the three- dimensional (3D) spherical display allows us to see images more naturally from any directions. This display can show not only surface information data, such as digital globes, but also 3D objects. Some user interfaces, such as multi-touch and gesture interfaces, have been implemented on this display. In this study, we propose a novel perspective-corrected stylus pen that can be used for 3D interaction with the display. The stylus pen has six Degrees of Freedom (6DoF) and can be used as pointing and drawing device in the 3D space within the spherical display. Therefore, the user can see the auxiliary line from the pen tip from a different angle. We demonstrated the stylus in terms of accuracy, pointing stability and how users can correctly perceive it in the 3D space. Some applications, such as selecting objects inside a virtual fish tank, were presented to show the usability of the proposed stylus.
