A more immersive Metaverse is here, the new “chemical touch” allows you to experience realistic cold and heat

[Guide] The future virtual reality touch may use chemicals on your skin to make you feel. Will this be the next step in making virtual reality and meta-universe more realistic? A new method developed by the Department of Computer Science at the University of Chicago: chemical touch can give the answer.

These days, it seems that every major technology company is talking about “meta universe”, believing that it will completely change our lives now.

On October 29th, Facebook CEO Zuckerberg officially announced that Facebook was renamed “Meta”. In the future, Meta will invest tens of billions of dollars to run towards the meta universe with all its strength.

Then, at the Ignite conference on November 2, Microsoft officially announced its entry into the “meta universe” and integrated its mixed reality conference platform Mesh into Teams. CEO Nadella said that the Xbox gaming platform will also join “Meta Universe” in the future.

On November 8th, AMD announced that it had won the large order for the data center of Facebook’s parent company Meta, which also means that AMD’s EPYC processor will be used in Meta’s new data center.

At the GTC 2021 conference on the afternoon of November 9, Nvidia further strengthened its determination to “enter the meta-universe”.

Huang Renxun announced the release of the artificial intelligence avatar platform (NVIDIA Omniverse Avatar) and an exciting major update to its Omniverse platform.

Avatars are interactive characters with ray-traced 3D graphics that can see, speak, and talk on a wide range of topics, and understand the intent of natural conversations.

Omniverse Avatar opens the door to the creation of artificial intelligence assistants that can be easily customized for almost any industry, helping to handle billions of daily customer service interactions, including restaurant orders, bank transactions, making personal appointments and reservations, and more.

And domestic companies such as Ali, Tencent , ByteDance, etc. have also placed bets on the meta-universe circuit to make arrangements in advance.

Luo Yonghao, who ” makes a friend, ” also tweeted to reveal his next entrepreneurial direction, “Unexpectedly” is also Metaverse.

Undoubtedly, the “meta universe” has become one of the hottest concepts at the moment, containing endless opportunities and possibilities.

However, if people want to experience the real world in virtual reality, they may have to wait until we can use all our senses, not just sight and hearing, for example, touch?

The goal of haptic technology is to allow users to experience the physical sensations simulated by other technologies.

Some of the earliest examples of this include cell phones and pagers, which use rotating motors and counterweights to generate vibrations to attract the user’s attention without making any noise.

In 1997, Nintendo’s first through- through the Rumble Pak N64 will be similar technology into the video game, which makes the game console controller with the game action shaking and vibration, this feature is now very common.

But just relying on vibration, a virtual reality headset or a pair of virtual reality controllers is not enough to simulate all the sensations that can be experienced in the real world.

As a result, researchers in the Human-Computer Integration Laboratory of the Department of Computer Science at the University of Chicago have developed a new method, which is to design an interactive device directly attached to the human body, apply local stimuli directly to the skin, and directly trigger the human skin in different ways. In the receptor.

This sensation through chemical interaction with the skin means a new form of tactile sensation, which they call chemical tactile sensation.

As stated in the paper, the researchers designed and manufactured independent wearable devices, as long as they can be in contact with the skin, these devices can be worn anywhere on the human body, arms, legs, and even the face.

The researchers designed a soft silicone patch that uses a micro-pump to push liquid medicine through a channel open to the user’s skin, allowing the skin to absorb them when the medicine passes through.

In this way, in addition to providing sensations that existing haptic devices cannot provide, the device also allows a single actuator to achieve multiple responses.

Wearable devices use silicone patches and micro-pumps to deliver five different chemicals to the skin surface, creating five unique physical sensations at the point of contact.

Currently, researchers have identified five chemicals that help produce lasting sensations: Sanshool, Lidocaine, Cinnamaldehyde, Capsaicin, and Menthol.

Menthol creates the feeling of cooling the skin, which may simulate walking outside on a snowy day, while capsaicin, the “spicy” ingredient in this spicy food, can create a feeling of warmth, simulating exposure to heat Something under.

Lidocaine can produce a numb sensation, and sanshool and cinnamaldehyde can produce a tingling sensation. These can be used as a negative form of tactile feedback in virtual reality games to remind players to protect their own safety.

All the chemicals used are safe for humans, so you won’t get hurt while playing virtual reality simulations.

Since this is a new method, the researchers also made recommendations on when and how to use chemical touch, showing that it is best suited for “slowly changing tactile events,” such as how the sting of a wound evolves or temperature in the first few minutes Slowly rising.

They also recommend adjusting the concentration of chemical substances according to the body position where the device is worn, prioritizing the selection of chemical substances according to the main sensation provided by each chemical substance, and some safety precautions.

In a user study, participants evaluated the immersion of virtual reality experiences with and without chemical haptics; in the vast majority of cases, participants stated that the use of chemical haptic devices did increase immersion.

The team believes that this proves that it is possible to chemically stimulate the skin to produce sensations, and since the skin can acquire sensations in this way, the details of these sensations can be fine-tuned in the future, including the conversion between sensations, mixing compounds, and customization. Chemicals to get a new feel.

The study, to experience virtual reality and haptic devices are not designed to bring new possibilities, breaking the boundaries, feeling stressed out vibration and pressure.

Is this the future of the “meta universe”?

I may look at it again in the future, it will not be exactly like what is shown now, but to find a new haptic feedback method is definitely a clear step in the direction of exploring the direction of analog haptics.
