AI Technical Summary
Technical Problem
Existing VR training systems using vibration-based tactile presentation do not account for the need for stronger tactile sensations when objects are heavy or movement is restricted, leading to discrepancies between virtual and real-world movements.
Method used
A system that combines display, vibration, and audio devices to control visual, tactile, and auditory parameters based on the attributes and state of an object in virtual space, using measurement devices to adjust sensory inputs in accordance with real-world constraints.
Benefits of technology
Enables users to feel the sensations of holding or moving objects with intensity suited to the situation, without requiring large-scale equipment, by integrating visual, tactile, and auditory feedback.

Abstract
To allow a user to feel a sense when holding or moving an object with strength matched with a situation according to the restriction of an actual operation.SOLUTION: The system includes a display device that presents a video of a virtual space including an object to a user, a measurement device that measures a motion of a hand of the user, a vibration presentation device that presents a vibration to the hand of the user, an audio device that presents a sound to the user, and a control device. The control device controls a plurality of parameters among a visual parameter of a video of the object, a tactile parameter of vibration of the vibration presentation device, and an auditory parameter of sound of the audio device in movement of the object in the virtual space on the basis of an attribute and / or a state of the object.SELECTED DRAWING: Figure 1
