American engineers have created a bracelet that complements the VR helmet with tactile stimuli. It can be compressed at the wrist or vibrate in different parts, and thus to simulate interaction with objects in the virtual world. The article will be presented at the conference CHI 2020.
The inability to qualitatively reproduce the haptic feedback from the objects is one of the key unresolved aspects of the VR and AR devices the current generation. Due to the fact that the user does not receive sensations from the manipulation of objects there is a mismatch between visual and tactile signals and a General sense of immersion in virtual reality is reduced.
At the current stage of development of technologies in serial devices, this problem is almost solved, and those that simulate physical contact, commonly used massive gloves with actuators. In perspective development engineers use and other structures but they are also usually quite complicated and cumbersome (as in the case of VR-fan).
Colonese Nicholas (Nicholas Colonnese), together with colleagues from the research division of Facebook, and rice University have developed a device, which in its capabilities and size is intermediate between the normal VR controllers, able to vibrate in his hand, and complex devices for qualitative simulation. The first version of the design was presented last year at the IEEE World Haptics Conference, and this year the engineers introduced a new version that can work simultaneously on both hands, and support more types of interaction.
There was supposed to be a video, but something went wrong.
The device is a bracelet consisting of one main segment and six smaller. The main link is connected to the other using a flexible polymer inserts, acting as springs, and wire rope. Inside the base segment is a motor that can pull the cable and thereby compress the bracelet around her wrist. So stress is distributed evenly inside the segments of the cable passes over a thin metal rod. Underneath each of the small segments is on one line vibroaction is the second way to affect the wrist in addition to squeezing.
