One of the problems with virtual reality is that it is so, well, virtual...but maybe not for long. Researchers at the Computer Vision Lab at ETH Zurich have developed a method to produce virtual copies of real objects that can be touched and sent via the Internet. This article talks about the efforts to create virtual reality you can touch.
In order to accomplish this, they’ve used a 3D scanner to record the image and dimensions of the object. Next a probe with a force, acceleration, and slip sensor collects information about the object’s shape and solidity, and a model is created on the computer. It can then be displayed remotely allow a user to sense the object using a haptic (touch) device and while viewing it with 3D glasses.
Not sure what the business implications will be but it does make for some interesting remote collaboration possibilities. Taking these approaches from a haptic pen to gloves or other more intuitive approaches would definitely make the experience more user friendly.
