Impacto electrical stimulation tactile feedback device is physically flexible
Release date: 2016-03-10
Virtual reality has been developing for a long time, but the progress in recent years has only begun to attract attention. It has been slow to develop over the past decade, and the emergence of Oculus has enabled the revitalization of virtual reality technology. Nowadays, consumer virtual reality products have made great progress, and the cheap virtual reality head image Samsung Gear VR has made virtual reality enter the public eye.
But there is one important factor missing, which allows users to really immerse themselves in the virtual reality experience. The status quo will soon change, as German researchers are tackling the problem.
A research team at the Human-Computer Interaction Laboratory at Hasso Plattner College in Germany has created a prototype device called Impacto. The device is integrated into a strap that can be attached to the user's arms, legs or feet. When combined with the virtual reality experience, coupled with the special software that human-computer interaction researchers use for the wearer, Impacto can simulate the touch, so that the wearer can feel the force feedback in the virtual world. At least to some extent this is the case.
The team gave examples of proofs, including a boxing demo, where the user can feel the feeling of being hit with a boxing arm, and a demonstration of playing football repeatedly with the foot, at the foot of the player, you can feel it every time. The interaction between the football and the foot when it falls.
It is worth noting that Impacto is not a simple vibration motor that is inserted into a plastic box to generate force feedback. The device incorporates a muscle electrical stimulation tactile vibration engine to create a push or pull feel, thus more realistically mimicking the feeling of actual physical object contact.
“The key concept is that the small and light Impacto device decomposes the stimulus to simulate a powerful blow; it uses the electromagnetic touch of the skin to produce a tactile feedback that is hit; it uses muscle electrical stimulation to cause the user's arm to be hit. And the power to push back," team leader Pedro Lopes said in Impacto's research paper. “The device is wireless, independent and lightweight, ready to wear, and free to move around in a virtual environment. The device is a universal shape that allows it to be attached to the leg to enhance the kicking experience, or to merge into a prop Such as a baseball bat."
