Abstract:
Three-Dimensional (3D) displays have been developed to allow users to view 3D objects from any angle. There are several input interfaces for interacting with this display, such as joysticks and gesture interfaces. However, in order to properly interact with the 3D objects in the display, the input interface needs to obtain its own 3D location from the 3D tracking device. In this study, we propose a low-cost pointing device for a 3D interactive display using an infrared camera and a smartphone instead of a 3D tracking device. The camera is set up at the bottom of the display to detect the contact point between the pointing device and the display surface. The pointing device gets its 3D orientation from the smartphone's built-in Inertial Measurement Unit (IMU). The proposed pointing device enables the user to see the auxiliary line from the device tip from different angles. We demonstrated some 3D pointing applications, such as selecting objects inside the display to show the usability of the proposed pointing device.
