Nausea: when virtual reality makes you want to vomit

Virtual reality offers experiences that are often rich in emotions. However, some users suffer from side effects that can be annoying to the point of totally ruining the experience. An update on these inconveniences that are often linked to motion sickness.

Cybersickness: the side effects of virtual reality

Many users reported suffering from dry eyes or headaches, but most often nausea. These symptoms, now known as “Virtual reality sickness” or “Cybersickness,” are similar to those experienced by some people in transport.

According to a study conducted by video game publisher Ubisoft, 45% of users acknowledged some discomfort during the experiment, and 6% admitted to having been particularly affected by these symptoms.

The reasons for nausea are known

For doctors, nausea experienced by some users has well-known origins. It is the same principle as kinetosis (motion sickness). Doctors explain that the brain can feel inconsistencies during a virtual reality experiment and its reaction is to cause nausea to indicate that something is wrong.

Indeed, the visual information he receives does not correspond to the data coming from the balance. The brain sees that the body is moving or accelerating but does not feel this information from the inner ear, which is responsible for sending information about the body’s balance and movements. Also, there is often a slight discrepancy between the movements of the head and the images, disturbing the brain. Low resolution or low image display frequency can also contribute to these unpleasant symptoms.

Recommendations of the experts

Experts who have studied cybersickness have pointed out some areas for improvement. First, the equipment. The headset and the associated computer or smartphone must limit the time lag between the display of images and head movements. Scientists believe that latency of 20 milliseconds should be the maximum tolerable. They also recommend a display frequency of 60 frames per second or more.

On the software side, experts advise application developers to avoid sudden or erratic acceleration movements. Scientists have also realized that the amount of information on the screen is essential. Indeed, the more elements of the decor likely to attract the eye of the user, the more he does not know where to look, making him more sensitive to nausea. Giving the player fixed landmarks is also essential. For example, experts recommend leaving a dashboard exposed in a piloting simulation application.

The difficult case of lack of movement and acceleration

Although the recommendations made above by the scientists partially correct some of the factors that can trigger nausea, the lack of correlation between the movements and accelerations visualized and those felt by the inner ear is not affected.

For this particular point, the most obvious solution is to use an armchair that reproduces the movements and accelerations reproduced on the screen. This technology exists and has even been used for years in some amusement parks. However, it is extremely costly and difficult to implement. However, researchers are working on another technology, simpler and cheaper, which uses a headset that sends electrical signals to the inner ear artificially reproducing movement and acceleration information. This technology is not yet fully developed.

Oculus deploys medical training modules in 11 hospital institutions

Oculus is being more aggressive in the medical training field. The virtual reality specialist revealed on the 29th of August that they will deploy new VR training solutions in 11 health institutions in the US.

The announcement follows Oculus’ partnership in 2017 with the Los Angeles Children’s Hospital (CHLA) to train medical students to respond to vital pediatric emergencies.


A 6-month pilot study was conducted last year around a simulation created by the start-ups AiSolve and BioflightVR to validate the effectiveness of this type of learning.

It was such a success that the hospital now requires all of its clinicians or assistants to undergo this training, and it is available as an option for all students.


As a result, Oculus and CHLA are expanding this research program to 11 additional institutions:

Columbia University Irving Medical Center, Johns Hopkins Children’s Center, Kaiser Permanente Health Network (Southern California), Medical University of Vienna, New York University / Langone Medical Center, Stanford University / Lucile Packard Children’s Hospital, University of Bern, University of Washington, Yale New Haven Health.

Oculus will provide them with Oculus Go helmets, the company emphasizing the simplicity of installation of the device: no need for a computer or a dedicated space, just to put on the device. Deployments will begin this fall.


Kathryn Schaivone, a specialist trainer at Kaiser Permanente, reported that at present they could only do training on critical incidents, such as pediatric resuscitation, between two and four times a year because they cannot monopolize their teams too often. Moreover, that virtual reality makes it possible to increase the frequency of participation in simulations.

The first module concerns pediatric resuscitation in the event of a crisis or shock. The next ones will work on other cases, as CHLA researchers hope to gather advice and opinions from their colleagues in other hospitals to determine good practices.

“Now that we have this proof of concept, we are thinking about other scenarios and skills that are considered infrequent but with high stakes, for example in areas such as emergency medicine, critical care, and obstetrics,” says Dr. Todd Chang, CHLA’s project researcher.


This Oculus announcement comes in a context of global growth for virtual or augmented reality training solutions.

The immersion phenomenon inherent in these technologies makes them more adapted to the retention of information for “practical” jobs than traditional theoretical training modules. In Europe, French companies are working on virtual learning for healthcare professionals, including SimforHealth, VirtualiSurg, and the Moveo Foundation.

Mozilla launches a VRChat clone

Mozilla launches a VRChat clone

Mozilla unveiled its virtual reality site yesterday. First Facebook then Google, it is the turn of the firm chaired by Mitchell Baker to offer us the means to communicate or meet other people via its site Hubs, a copy of VRChat.

Hubs is a social space in virtual reality that allows exchanging with one or several individuals at the same time. If it is only an experiment for the moment, Mozilla intends to realize this project and improve it. Just like VRChat, Hubs uses for the moment, rudimentary graphics, similar to that of the PS1 and almost no details. We’re a long way from the Ready Player One Oasis. The organization continues to experiment with new, more realistic avatars and more personalized spaces.

Hubs: VRChat at your fingertips

The Hubs website, unlike Facebook and VRChat, is easier to access. Indeed, to access this world, there is no application to download. It runs on a browser. For Mozilla, “the web offers the best future for virtual and augmented reality”, “No application store. No doormen. No installation process.

Then Hugs works on all VR helmets: Oculus Rift, HTC Vive or Daydream and Cardboard helmets. Mozilla says, “You can even use your desktop computer or mobile phone if you don’t have access to any VR equipment. Everyone can meet and communicate with each other in this online social space.”

Disney Unveils Haptic VR Virtual Reality Jacket

Disney Research unveils a haptic return jacket for virtual reality. The “Force Jacket” allows users to feel the sensations of physical contact in the VR and could allow the entertainment giant to create new immersive attractions…

The future of virtual reality will pass through physical sensations. At least that’s what Disney Research seems to think, which has just unveiled a haptic jacket for RV. Called “Force Jacket,” the device simulates physical contact sensations through pneumatically operated airbags.

To put it simply, the jacket has 26 air pockets connected to a machine through tubes. The device inflates and deflates the air pockets precisely at the right time. Thus, combined with a virtual reality experience, the jacket can allow the user to feel the physical sensations that his avatar feels in the game.

As an example, Disney evokes the contact of a snowball. It would also be possible to use such a system to simulate the impact of a punch in a combat game, or a ball in a shooting game. In short, the Jacket Force could add the sensations of touch into virtual reality, increasing the realism of the experiences and therefore the feeling of immersion.

Disney could establish itself as a technology leader in virtual reality.

Disney Research is not the first company to develop a haptic return jacket. However, this pneumatic system seems more ingenious than the electrical stimuli offered by most manufacturers. Moreover, Disney has more financial means than a simple startup to complete its project. So this haptic jacket could be revolutionary for virtual reality.

Unfortunately, it is unlikely that this accessory will be offered for sale to the general public. Instead, Disney Research explores the possibilities offered by RV for the American company’s amusement parks. As a reminder, Disney has already partnered with The Void to create the Star Wars Secrets of the Empire attraction, offering four players the opportunity to evolve simultaneously in virtual reality and a landscaped space in the real world. This new invention could bring even more breathtaking attractions to life.

A new version of the dji goggles headset for drone pilots

Drone races are now very real. There are championships held all over the world. It is therefore not surprising to see some manufacturers offering products targeting this particular target group. The Chinese drones manufacturer DJI is one of them and now offers a new version of the DJI Goggles.

The DJI Goggles helmet was launched last April. Similar to a virtual reality helmet, this one allows the user to control his drone by moving his head. It can also offer a vision to the first person as if it were inside the drone.

New Racing Oriented Version

If the DJI Goggles was offered for sale in white, the new version dedicated to drone races and named DJI Goggles RE – for racing edition – is available in matt black, with red leather on the head circumference.

The DJI Goggles RE is also compatible with third-party drones and steering levers such as the Naze or F3. Features include video streaming with the OcuSync Video Transmission Module and Sphere panoramic viewing.

Users can also connect two headsets so that another person can board, and take control if they wish. DJI will deliver the first units of its DJI Goggles RE in the coming days at the indicated price of 499$.

The DJI Goggles in Racing Edition can be used with a wide range of drones including the Mavic Pro, the test DJI Spark. the Phantom 4 and 3 series as well as a bunch of other non-DJI drones!

Vrvana and apple

Apple Acquires Augmented Reality Headset Manufacturer

Apple company recently discreetly acquired Vrvana, a Canadian manufacturer of a helmet that oscillates between virtual reality and augmented reality.

This is a new step for Apple in its quest for an augmented reality helmet for 2020. According to Techcrunch, Apple bought the helmet manufacturer Vrvana (pronounced “Véairvana”) for $30 million. Contacted by the media specialized in new technologies, Apple has neither confirmed nor denied this information.

Vrvana is a Canadian company still in its infancy in augmented reality. Founded in 2005, it would have received only $2 million in funding to date, a minimal amount to develop a physical product. However, its Totem helmet, for the time being, a prototype, impressed observers when it was launched last year.

While the purchase was not directly confirmed, secondary sources assured Techcrunch that the transaction had been completed. Vrvana employees would already be working at Apple, and the Canadian company has not been communicating over social networks since August.

Augmented Reality Pioneer

With the launch of its Totem, Vrvana has developed the concept of “extended reality,” between virtual and augmented reality. As virtual reality players in north america explains, VrVana made a helmet in the form of a virtual reality helmet, covering the user’s entire vision, but added cameras on the front of the helmet to film the real world. This hybrid system made it possible to locate the user’s hands in infrared while integrating into a 3D world.

One of Vrvana’s advantages is also to offer virtual projections on the real world in color and opaque, while other augmented reality headsets like Microsoft’s Hololens can only display ghosts in black. However, Vrvana encountered a problem of too high latency, which hampered its use.

Businesses, the first targets?

More broadly, this acquisition should allow Apple to accelerate in the design of its augmented reality helmet. Unveiled by Bloomberg on November 8th, Apple’s effort to build its helmet seems increasingly consistent. Unofficial information already reports a team of several hundred engineers and the design of a specific operating system called “rOS” for reality Operating System.

While the apple firm is always looking to diversify and gain a foothold in the business environment, the acquisition of Vrvana could be a significant asset.

Drones and Virtual Reality

In recent years, UAVs have become one of the most popular pieces of technology. Both in the military, security and surveillance and leisure sectors. With the advent of virtual reality, the meilleurs drones full HD will be able to reach a new milestone that will offer a degree of immersion and possibilities for users never before reached.

“We can’t stop progress anymore,” as the saying goes. UAVs and virtual reality are two of the most interesting advanced technologies today. Not surprisingly, manufacturers have begun to mix them to open up new horizons. The main objective of the drone with virtual reality? FPV? We explain what it is and what model to choose.

What does FPV mean?

FPV or First Person View is a term that will undoubtedly appeal to video game fans. Of course, it’s reminiscent of the term FPS, or First Person Shooter. These games like Counter-Strike, for example, propose to play the character. In the case of drones, the logic is the same. The user can see what the camera is observing from the front of the drone. He doesn’t see the object he’s directing, but what he sees. In other words, with advances in terms of cameras or reactivity, potential uses are multiplying. We are talking about discovering panoramas seen from the sky as much as freestyle between trees or even drone races.

parrot disco bird

Parrot Disco FPV: this is the name of a drone intended for private individuals, mini portable aircraft that the user will control using a remote control. Able to withstand winds of 40 km/h and to fly up to 80 km/h and sold for the modest sum of 1100 dollars, this small remote control plane will be supplied with a virtual reality helmet designed by Parrot company also and with the aim of offering the user the possibility to follow the flight of the drone itself, equipped with a 360° camera. This will allow the “pilot” to maneuver with greater accuracy and recoil than if he or she were using a simple screen mounted on the joystick.

Drones of tomorrow

It is very likely that tomorrow’s drones will all be equipped with the same technology, as GhostDrone 2.0, which we were talking about a short while ago, is already doing. Designed to be used via smartphones to minimise the cost of helmet construction, consumer products using this technology are increasingly available on the market. Not surprisingly, virtual reality offers new possibilities and undoubtedly impressive panoramas.

Imagine flying over fabulous live panoramas and your own wings. The same freedom as if you were really flying, and no, it’s not a virtual world this time. The process is excellent and will help budding pilots and handle some of the tricky passages with more control.

However, since pausing is not really possible, you will have to make sure that you are well protected from any external disturbances for the duration of the flight if you don’t want to remove your helmet in flight and risk damaging your precious drone!
