"VR 2014" Unicom Virtual and real-world bridge how can not

from the perspectives of display equipment, interactive products, content production platform, transmission technology, cloud service, media and distribution.

VR 2014 is a series of reports on virtual reality startups in the 2014, which will present 2014 years of China's virtual reality entrepreneurial ecology from the perspectives of display devices, interactive products, content production platforms, transmission technologies, cloud services, media and distribution. If you are also a VR entrepreneur with good VR ventures and ideas, have an understanding of the industry, welcome to email Contact (syq#36kr.com).

In the past many years, the computing power of the equipment has been increasing, let us be full of information about the future of computing equipment. The virtual reality display device represented by Oculus, bringing magic back to the world, is likely to become the next generation human-computer interface. It seems that the future has come.

At the moment, you are immersed in the excitement of the Rift coaster, and now you are immersed in the dreadhalls of fear, and at the moment you are immersed in the war thunder ... At this time, with a head-wearing display of you, press the keyboard and mouse, forward back, left flush right. A moment of immersion, you go back to reality, study, computer desk, 23 years old, working family, the boss in the reminder draft ...

Don't laugh, this is the future of cool technology before the realization of the reality. Now and then, in order to see the keyboard and move away from the display, to drip, the reality is so anti-human. If there is a new way of interaction, can let virtual reality players in with the top of the display, but also can interact like the real world, is not a lot of science? Oculus also like us, the acquisition of Nimble Sense, 13th Lab, gave the gesture recognition of official support and endorsement.

Is that enough?

Unlike machines, people are a kind of sensible species, with a number of sensory senses that can accurately perceive pressure, vibration, etc. Take the hand as an example, even in the night, grasping, holding, sliding, these different dynamics of action, we can do in place; the size and shape of an object can be "at a glance" through the touch of the hand. It is said that human dynamic touch can distinguish between a height of not more than 13 nm, that is, 0.0000005 inches, probably equivalent to the size of a molecule.

What a magical power this is. It represents a kind of feedback, is the appearance of the result of human-computer interaction, this kind of presentation is the auxiliary display of visual rendering, but it is equally important. Not so, the paradox of the Moravia always exists. Virtual reality to some extent break through the limitations of two-dimensional screen, the interaction is not limited to sliding, click. This feedback is equally important in a three-dimensional interactive interface.

Imagine, in the virtual reality world, after wearing a monitor, you can also see your hands in the game, grasp a virtual water cup, but also get a force feedback, in the virtual world and the real world there is a touch of touch, such interaction is not very attractive.

That's what Dexmo is doing. To get a clearer picture of their projects and products, let's take a look at a video.

In short, they are using the mechanical exoskeleton, the bending of the hand through a group of connecting rod decomposition map to the rotating sensor, and then through the software model, calculate the position of the shot, using the calculated coordinates point of the inverse kinematics analysis of the finger, to capture the hands of action.

In the past, with strong feedback of hand motion detection equipment, the most famous has Cyber Glove System Cyber grasp. The device for enterprise-class customers, hand action detection and force feedback is divided into two sets of systems, not only made expensive (price of hundreds of thousands of U.S. dollars), bulky, in addition to the hands of the outside skeleton there is a bulky driver box placed on the ground. Dexta Robotics finally used a completely different force feedback method on the Dexmo and Cyber grasp. Dexta Robotics founder Gu Xiao Chi is "driven by the power of hand feedback," the inventor, in the United States and China are holders of relevant patents. They make the system of hand force feedback smaller and lighter, integrated with the motion detection system throughout the hand exoskeleton, making the whole outfit more compact and portable and easy to wear.

This September 19-20th, Oculus VR convened the first developer conference called "Oculus Connect". This session of the Developer Assembly for the invitation system, Dexta Robotics got the invitation letter. In October this year, DEXMO launched a public fund-raising campaign in Kickstarter, which plans to raise 200,000 dollars. However, fundraising was cancelled for a variety of reasons. For developers who have just entered the VR field, the action-capture device, which has been able to deliver robust consumer feedback, is too early.

It doesn't matter. Oculus acquired Nimble Sense, 13th Lab, gesture recognition has completed the most basic and natural input. The next step is feedback.
