Together with the virtual reality glasses, Samsung Entrim 4D headphones will let you fully experience virtual reality
With a virtual reality glasses, your immersion experience may be still limited. This is why the Entrim 4D is born to trigger your ear, by regulating your balance and motion, to make your feel really presence in the virtual reality world.
A safe and simple technique GVS - Galvanic Vestibular Stimulation is skilfully combined with various algorithms, to send the electric signals to a nerve in users' ear. Thanks to this technique, users can feel themselves like a part of the on-screen action. They will not just see but also sense direction and speed of movement.
The Samsung Entrim 4D is used simultaneously with the VR headset to help you fully immerse into the virtual world
GVS is also used as a medical word in medical treatments of "vestibular disorder". According to vestibular.org, it is written that "Sensory information about motion, equilibrium, and spatial orientation is provided by the vestibular apparatus, which in each ear includes the utricle, saccule, and three semicircular canals. The utricle and saccule detect gravity (vertical orientation) and linear movement."
A person who is treated with GVS shared that he feel an urge to move on the right side when the researchers press the remote control. He added that his body is automatically forced to do that as if it is an only way to keep balancing. He agreed with researchers this phenomenon is absolutely not causing any offensive, but it's just very confusing.
Samsung also has their way to explain the users towards this electrical signals: "they are like the ones used to help restore balance in stroke patients—are delivered via headphones equipped with electrodes that correspond to movement data input by engineers."
Steve Jung, Creative Leader of the project also emphasizes: “Virtual reality shouldn’t be experienced only with the eyes,” but with their whole bodies.
Maybe this new invention still needs more lab test before massly debuted
In theory, both games and movies can use Entrim 4D. Samsung hopes that by matching the sensation of movement in your body to the experience you're seeing on its headset, not only the VR experience will be improved, but motion sickness can be gone away.
Entrim is still in the development stage, as so far Samsung only lives its demos at SXSW. Therefore, the whole public must stay patient and wait for the release date and price for a while.
