Space interface device for artificial reality—SPIDAR

Abstract

AbstractTo realize the human interface which efficiently models a three‐dimensional shape on a computer, it is necessary to provide an environment in which the shape model can be manipulated directly as the actual three‐dimensional object. Such an environment is called the virtual work space. In the human manipulation of an object by hand, such sensations as visual, tactile (touch), and force are utilized unconsciously.To compose the virtual work space, it is important that the human be given such sensory information in an integrated way. Such information must totally be generated artificially by computer processing. Based on such an idea, this paper proposes anew a space interface device called SPIDAR, as the I/O device needed in composing the virtual work space. The device functions to derive the information concerning the finger position and to provide the force sense information to the finger tip.The virtual work space for generation and manipulation of the three‐dimensional shape is composed using SPIDAR. An experiment is conducted to examine the effect of the force sense on the direct manipulation of the three‐dimensional shape in the virtual work space, and the usefulness of the method is verified.
