To make VR more real, many people have been working hard for it. Recently, the team of researchers at the University of California, San Diego, developed a smart glove that uses 3D printing and soft robots to develop this glove, which can be used in VR environments. The user provides tactile feedback. Although this glove is still in the prototype stage, it has successfully simulated the touch of the piano. Moreover, the team recently exhibited the work at the Virtual Reality Electronic Imaging and Engineering Reality Conference in Burlingame, California, leaving a lasting impression on the participants.
Unlike bulky materials (such as metal) used by other VR haptic devices, the team uses a lighter, more flexible soft robot to make VR gloves. Soft robot components are called "latex covered with woven fibers." For exoskeletons of VR gloves, the researchers used a 3D printed mold. The team stated that 3D printing will make manufacturing and mass production equipment easier. Prototype gloves use silicone rubber with Velcro as the exoskeleton.
The robot glove consists of three main parts: the Leap Motion sensor, which detects the position of the user's hand; the fluid control board, which controls the glove movement; and the soft robot part that can be inflated or deflated, depending on the user in the VR world. Hand movements are designed. Its contraction and expansion can effectively imitate the tactile sensation of different objects in real life.
To test VR gloves, the team invited fifteen users (two of whom were VR experts) to try to play the virtual piano. Positive gloves are linked to real-time interactive computer monitors that can display virtual hands and keyboards. Finally, the test user was surprised by the quality of the feedback and pointed out that the gloves were very responsive.
At present, the team of engineers are working hard to improve their VR glove designs and hope to make them lighter, smaller, and of course cheaper. Tolley concludes: "Our ultimate goal is to create a device that can provide a rich experience in VR. But it can also be used for surgery and video games, as well as other applications."
