7 Practical AR Uses In Healthcare

Avatar

Published

on

Who said that augmented reality (AR) was just for gaming? You heard right! AR can also be useful in industries such as healthcare. Despite its infancy, AR can be useful in the following areas in healthcare:

  • Health awareness
  • Prevention
  • Diagnosis
  • Treatment (i.e., medical, therapy, etc.), AND
  • Health maintenance

So, how can healthcare organizations take advantage of these limitless possibilities? Here are 7 ways that AR is effective in healthcare (with examples)!

  1. Vein Detection

“Vein detection is more possible with AR,” says Jasmine Brown, a tech blogger at Ukwritings and Eliteassignmenthelp. “AR vein detectors use laser light interaction with hemoglobin molecules and spectroscopy to check the concentrations in patients. Afterwards, the devices can project a high-resolution image that highlights where the veins are in the patient. Unlike full-field digital mammography, which uses low-dose radiation to produce images, AR vein detectors don’t use radiation, which is safer for patients.”

AccuVein is a portable AR device that helps nurses locate veins in patients. Available in over 130 countries (including the United States), this portable vein finder can be purchased or leased as a prescription.

  1. A Means To Educate Patients

Rather than just telling patients what their health problems are, AR can enhance medical services by actually showing patients what the problem is. During consultations, patients can use AR to better understanding their conditions.

In Utah, Orca Health has experimented with a medical AR app called EyeDecide, which allows eye doctors to visually demonstrate to patients how cataracts can affect the eye. By simulating various conditions of the eye, patients better understand their eye problems.

2. Surgeries

Surgeries can be terrifying for patients, especially when thinking about the consequences of doctors cutting open their bodies. However, AR has the potential of using noninvasive surgical procedures. Plus, surgeons can use real-time patient information to monitor how things are going during surgery.

TrueVision is currently developing AR-based surgical tools that assist doctors in the following areas:

  • Neurosurgery
  • Ophthalmology
  • Microsurgeries

The company’s Digital Microscope Platform can generate digital surgeries that convert current microscopic technology into AR-based 3D images.

3. Defibrillator Tracking

GPS-tracking is no longer reserved for looking for nearby restaurants and facilities. In fact, it’ll soon be possible for people to GPS-track defibrillators that are near them. You never know: You or someone else may collapse all of a sudden, and will need medical help right away.

An Automated External Defibrillator (AED) is a device that automatically detects cardiac conditions. But where to find them at a time of need? That’s why Lucien Engelen created the AED4EU app, which uses AR technology to track defibrillators near users without them having to scramble to get help for someone who has fallen.

4. Breastfeeding

For mothers struggling to breastfeed their children, AR can help them understand their conditions better. That’s where products like Google Glass come in.

Innovation company Small World (in conjunction with the Australian Breastfeeding Association) experimented with Google Glass to show doctors and counsellors the mother’s perspective of breastfeeding, as she wears the AR device. Mothers can show doctors their breastfeeding without putting down their babies.

5. Clearer Drug Information

“AR is also seeping into the pharmaceutical arena,” says Corey Barge, a business writer at Revieweal and OX Essays. “Patients can use AR devices to see how a drug works in the body. Lab workers can also use these devices to see how their medicinal experiments are doing as they create them.”

As of October 2020, Random42 has experimented with creating pharma AR apps that will allow users to see how medicine and other scientific products work.

6. In-Hospital Navigation

Finally, it can be intimidating to navigation through a hospital, and not know where you’re going. But what if AR was there to steer you to the right lobby or the right recovery room?

Developers like the Rochester Institute of Technology (in conjunction with Rochester Regional Hospital) understand that a hospital can be a labyrinth for patients and their loved ones. That’s why the organization experiments with AR technology to help users (patients and or loved ones) locate the right places to go to in a hospital without losing their way.

Conclusion

As you can see, AR holds a lot of potential when it comes to treating patients and saving lives. With these 7 prospects in mind, augmented reality will soon dominate healthcare in its institutions and practices.

What Are Texture Maps And Why Do They Matter For 3D Fashion?

Avatar

Published

on

Texture maps are essential to make your 3D images look real. They are applied to 3D models to create special effects, patterns or repeating textures. There are many different types of texture maps, but they all fall within two categories; PBR or Non-PBR.

PBR stands for Physically-Based Rendering and renders an image the same way it would look in the real world with physics based lighting. PBR is used in real-time applications like Unity and Unreal game-engines as well as the web. This is fast becoming the standard as many fashion brands realize the benefit of 3D on the web.

3D eCommerce has proven to double online conversion rates while using 3D in B2B sales has allowed brands to lower their carbon footprint, increase speed to market and reduce costs by replacing physical samples with 3D models.

https://medium.com/media/c64b44dee98fdcbad261a2fc7f71e45f/href

The most friendly real-time PBR file format is glTF or GLB and is supported by The Khronos group, a non-profit consortium of companies from HP, Apple, Adobe, Facebook, and more. glTF has a very well defined specification and can be used in game-engines as well as the web.

Non-PBR materials can give you very photorealistic results as they have many different settings to play with. This however, makes them much more complicated to learn. You also can not use these on the web, VR or AR so we will focus on PBR.

We’ll look at the following PBR maps which are most applicable to fashion:

  1. Albedo
  2. Normal
  3. Roughness
  4. Metalness
  5. Height
  6. Opacity
  7. Ambient occlusion
  8. Refraction

Albedo

The Albedo map is the base color input that defines the diffuse color or reflectivity of the surface. This is very similar to a diffuse map but is more the pure color of an object, while diffuse is both color as well as shaded with some diffuse lighting.

4. Enterprise AR: 7 real-world use cases for 2021

Normal Map (aka Bump Map)

Normal maps give your object texture and depth by changing the direction light is reflected off your 3D model. These are also known as Bump Maps because they make your surface look bumpy. Normal maps don’t actually change the geometry of your 3D model so you can’t use them for extreme depth, but they are great to give realistic textures while keeping the polygon count low. Below is an example:

The left is a cube with a color texture while the right is the same cube with a normal map that gives it the brick texture. Normal map looks like the below when separated out from your 3D model:

Roughness Map

The Roughness Map (or Gloss Map) defines how light scatters across the surface of your 3D model. A 0 for Roughness results in a very shiny surface like plastic while a 1 is a more matte look.

Metalness or Metallic Map

Metalness maps are fairly self explanatory. They define whether the material is made of metal or not and work on a 0 to one scale. In fashion, metalness maps are most often used for trims.

Below are examples of these three maps and how they compare to each other:

Height/Displacement Map

Height maps are similar to Normal maps except they actually alter the geometry of an object. They are used to show more detailed elements of a material, but are usually only used in high-end game engines like Unity or Unreal or when being rendered within a program. 3D on the web currently doesn’t support them so it’s best to bake them in when exporting a 3D model that will be used on the web.

Opacity Maps

Opacity maps allow you to make certain areas of your texture transparent. If you wanted to create an effect like that you would see on a leaf, you can use an opacity map to make some areas transparent and some opaque. White is fully opaque and black is fully transparent.

Source: https://mimari3d.blogspot.com/2014/12/how-to-use-opacity-maps-in-3ds-max.html?spref=pi

Ambient Occlusion

Ambient occlusion (AO) is a map that the PBR engine combines with the albedo at render time to define how it reacts to light. A simple way to think about it is that instead of a very harsh shadow being cast, AO creates softer & more realistic global shadows around the edges of objects.

Rather than remaining black, shadows dissipate into halftones and obscure places that get less light.

Refraction

Refraction is the term used to describe the change in direction of a light wave due to a change in its transmission medium. In other words, when light comes in contact with certain surfaces, like water or glass, the light will get slightly bent because those surfaces affect the speed at which light travels through them. Refraction maps are a constant value that account for the amount of refraction in materials like water, plastics, etc.

Why Learning About Textures Maps is Important

One of the reasons it’s important for fashion designers to learn about texture maps is that it can help them diagnose issues when exporting from design programs. Browzwear and Clo are the two most popular apparel design softwares, both of which export glTF however sometimes the model you export doesn’t look the same as what you’re seeing in your design program. This is often due to an issue with one of your maps.

For instance, assets exported from Clo can often appear shiny, this is because Clo does not properly export the intensity value defined for the roughness property of your material. The way to fix this is to use a roughness map rather than an intensity value as this will ensure that any web viewer or game-engine will understand exactly how to render the roughness property.

Keyshot is another popular 3D design tool used for footwear and apparel. This program can utilizes proprietary materials to get photorealistic renders. While it has “PBR” settings, these materials are meant for progressive rendering and not realtime. Therefore, the materials you export do not always match what you see in the renders. Having an understanding of texture maps and their purpose can help you to understand what you may need to tweak to get the models looking correct up export.

Finally, many programs take advantage of V-Ray materials. V-ray materials are great for rendering images and videos, but cannot be used for real-time rendering. You’ll often see them used for materials like fur or fleece. The process of converting these materials can be pretty complex but VNTANA has helped automate this conversion process so you can save time and headache.

In order for 3D designers to take their designs to the next level they need to have a good understanding of textures, what they mean, and how they can improve the look of their garments. VNTANA can help 3D design teams improve and automate their processes and use their assets in eCommerce, b2b showrooms, and game-engines.

When Facebook launched the Oculus Quest 2 latest year you could upgrade your virtual reality (VR) experience with a range of accessories such as Oculus’ Elite Strap or VR Cover’s range of facial interfaces. Logitech also came up with its own product line with the G333 VR Gaming Earphones and G PRO Gaming Headset. But these were only available in the US. Until now of course, with UK Oculus Quest 2 owners now available to purchase them.

Logitech G Earphones

Because both products have been designed to easily integrate with the standalone headset they both feature custom shorten cables so you get premium sound without the hassle of normal headphones cables getting in the way. And thanks to Facebook partnering with Logitech, they’re both Certified Oculus Ready.

The Logitech G333 VR Gaming Earphones feature dual dedicated audio drivers, one for highs and mids, and one for bass, contained within aluminium housing and connected by flat cables to ensure they don’t twist. In the box you also get small, medium and large ear tips and three velcro straps to hold the cable in place.

As for the over-ear G PRO Gaming Headset it has the same core audio technology and build quality the original PRO has – 50mm drivers, passive noise isolation – just with that shorter cable. Customers will also find in the box a detachable mic with full pop-filter, a cable with inline volume and mute; a PC splitter for separate mic and headphone jacks, and a USB external sound card.

Logitech G Quest Accessories

“The teams at Oculus and Logitech G share the same passion for gaming and the same ambition to push innovation, design and technology to new heights. We are proud to be partnering with Oculus to deliver a next-gen Oculus Ready VR audio experience,” Vadim Kogan, head of business development for VR and AR at Logitech in a statement. “The Logitech G333 VR Gaming Earphones and the PRO Gaming Headset have both been thoughtfully designed to support VR set up and to provide the most immersive and refined audio experience possible.”

That’s not all Logitech is getting involved with VR wise. As part of Oculus Quest’s v28 update, you’ll be able to see the Logitech K830 in VR, making typing much easier. Although, at the moment it’s not a UK product.

Logitech’s G333 VR Gaming Earphones and the G PRO Gaming Headset are available now, retailing for £44.99 GBP and £84.99. For all the latest accessory updates for Oculus Quest 2, keep reading VRFocus.

Today, Bandai is announcing the Tamagotchi Pix: a combination of its classic Tamagotchi pet-rearing toy line with a new built-in camera for taking pictures with your digital pet.

The Pix is shaped like a hatching egg, with the top part of the “broken shell” working as a shutter button. Using the camera, you can insert yourself (and friends) into photos with your Tamagotchi, with appropriately cute photo frames. We’ve reached out to Bandai for more information about the camera quality.

Photos taken with the Pix are stored locally, and any photos you take will appear in a feed that documents your time with your pet. Bandai frames this as a sort of on-device social media, but because the Pix can’t connect to Wi-Fi and sharing photos is…
