The combination with robotics is indeed a possible future direction for VR. Just as at the Game Developers Conference in March, former Disney Dream Engineer Jesse Schell predicted that robots would be used in the VR industry by 2025. Robotics is a must if we want a true immersion experience.
VR technology is developing very rapidly at the visual level, but in order to further enhance the user's immersive experience, we also need to think about other human senses, such as touch. Quaker.com has repeatedly mentioned the tactile feedback devices developed by some start-ups, such as TacTIcalHapTIcs, NullSpaceVR, UnlimitedHand and Teslasuit, which have a common feature. They simulate the user through electrical stimulation and vibration. Tactile sensations in a VR environment.
Recently, a user named Scott Devine on Youtube uploaded a video showing how to use the Baxter robot and the HTCVive controller to simulate the haptic effect of pushing three boxes in the VR world.
In the video we see that when the user's Vive controller starts to approach and push the wooden box, the robot will automatically traverse a piece of wood in front of the controller, and the user will also push Baxter in the real world when pushing the virtual wooden box. A wooden board on the robot arm for highly realistic tactile feedback.
In addition, the robot can adjust the resistance of the user when pushing the wooden box in real time according to the different weight of the wooden box. Perhaps this has little effect on the push box experience, but in some virtual environments, in the user When he lifts a heavy object, he gets a rather small reaction, so his immersion will be greatly reduced.
Of course, it seems that the above tactile feedback scheme is still immature. On the one hand, the cost is too high. It is understood that to copy a complete physical space requires at least three Baxter robots, each of which is worth $25,000. This configuration is generally only present in large enterprises and military industries. field. On the other hand, we can see in the video that the robot's motion is still relatively blunt, and there is still a certain delay between the scenes of the virtual world, and at present, only some simple tactile feedback actions can be completed. There is still a long way to go to match the full VR application.
