Microsoft developed 3D touch screen that identifies virtual objects by touch

Microsoft developed 3D touch screen that identifies virtual objects by touch

In Redmond are busy creating what could be the evolution of the screens. The group project Natural Interaction Research (Natural Interaction Research) from is intended that the user can “touch and feel objects in a virtual world.”

On paper, the concept is simple. When the person touches a certain figure on the screen, you can feel by touch the shape of the figure is “pressing”. This is achieved through a robotic arm that is connected to the screen, and depending on the pressure of the user’s fingers and the physical model simulated application.

The example shown in video is pretty self explanatory. The three boxes on the screen have different masses, so they respond to different pressures applied with the finger on the screen, then the robotic arm is used to simulate the resistance of the object you are trying to push. Being a 3D display, glasses complete the visual part of the experiment.

However, a major challenge for the team was trying to simulate the shape and contours of an object, something that may seem more complicated given the restrictions. But playing with the depth of the screen was possible to achieve a simulation simple, but effective. According to the researchers, it was to the point that some blindfolded users could recognize the shape of simple objects (pyramids or cylinders) only through touch.

Michel Pahud, one of the project scientists, roughly summarizes what they want to achieve: “When the fingers press the sense of touch screen mixed with stereoscopic vision. And if we come up with the correct convergence of the screen and let the images cooling steadily to that fit with depth perception of the fingers, the information received by the brain should be enough for the virtual world is accepted as real ” .

The research team hopes that this technology can be used in the future in various fields, either from 3D games to educational or medical fields. Meanwhile, continue to focus on improving and refining the experience, reaching a point where even they can recognize textures.
