Researchers create virtual smells by electrocuting your nose – TechCrunch

Published

on

The IEEE has showcased one of the coolest research projects I’ve seen this month: virtual smells. By stimulating your olfactory nerve with a system that looks like one of those old-fashioned kids electronics kits, they’ve been able to simulate smells.

The project is pretty gross. To simulate a smell, the researchers are sticking leads far up into the nose and connecting them directly to the nerves. Senior research fellow at the Imagineering Institute in Malaysia, Kasun Karunanayaka, wanted to create a “multisensory Internet” with his Ph.D. student, Adrian Cheok. Cheok is Internet famous for sending electronic hugs to chickens and creating the first digital kisses.

The researchers brought in dozens of subjects and stuck long tubes up their noses in an effort to stimulate the olfactory bulb. By changing the intensity and frequency of the signals, they got some interesting results.

The subjects most often perceived odors they described as fragrant or chemical. Some people also reported smells that they described as fruity, sweet, toasted minty, or woody.

The biggest question, however, is whether he can find a way to produce these ghostly aromas without sticking a tube up people’s noses. The experiments were very uncomfortable for most of the volunteers, Karunanayaka admits: “A lot of people wanted to participate, but after one trial they left, because they couldn’t bear it.”

While I doubt we’ll all be wearing smell-o-vision tubes up our noses any time soon, this idea is fascinating. It could, for example, help people with paralyzed senses smell again, a proposition that definitely doesn’t stink.

Google Play Store cuts developer tax for subscriptions by half

Published

on

The industry practice of “70/30” revenue cuts between developers and app store owners have been put under a microscope in the past few years, especially after Epic Games made some big noise about it. It did force a few platforms to make changes to their policies, usually reducing the so-called “developer tax” under certain circumstances only. In general, however, storefront owners still take 30% of the profits by default, but Google is making a significant change in that policy to push subscriptions to the forefront.

Like many things in businesses, the 70/30 revenue split became a de facto standard without any explicit consensus among industry players. Giving store and platform owners 30% of profits might have worked well for the likes of Steam, where each product often sells in double digits, but it didn’t translate well to the mobile app market. Unfortunately, that has been the status quo for many years, which really hurt developers that sold their apps for an average price of $4.99 or even less.

It may be even worse for apps and services whose profits may come on a monthly or annual basis. At the same time, however, the likes of Google and Apple are trying to push the subscription model as a more viable and sustainable strategy compared to one-off payments for apps. In order to incentivize this model, Google is making it more attractive for developers to switch to subscription fees by lowering the tax they have to pay.

Starting January next year, the service fee or anything sold via Google Play Store will be reduced from 30% to 15%, meaning developers and publishers take away 85% of any of the revenue they make. Previously, Google allowed that same cut but only after 12 months of a recurring subscription. This change follows another big move last April when it cut the revenue cut to 15% for the first $1 million of a developer’s revenue.

Google is also adjusting some of the figures for ebook publishers and on-demand music streaming services. They can get their service fee reduced to as low as 10%, but only if they take part in Google’s Play Media Experience program. This program, the Android maker says, encourages publishers to target most or all of the devices where Android is available, making sure that the same experience and content is present in cars, TVs, and even smartwatches.

Skype now works also on Firefox after two years

Published

on

When the video conferencing trend kicked up last year thanks to the COVID-19 pandemic, it was no surprise that Microsoft would jump on the bandwagon as well. What was a bit surprising, however, was that it prioritized bringing its younger Teams platform up to snuff instead of promoting the video conferencing service it has had for years. In fact, some might have almost forgotten about Skype at this point, including Microsoft. Two years after launching its new Web app, Microsoft has finally made Skype work on Firefox, though not without what might be an unnecessary warning.

Granted, there is a Skype desktop app anyway, so a Web browser experience might sound redundant. Not everyone, however, might want to install a separate app just for the occasional call, and not everyone might be keen on using Microsoft’s blessed browser. Depending on which browser you do prefer, however, you might have felt snubbed by Microsoft.

Switching Microsoft Edge from its homegrown edgeHTML engine to Chromium did mean that similar browsers like Chrome and Opera were able to support the new Skye for Web experience. Safari users on Macs, however, waited until May this year to be able to use Skype in their browser of choice.

Now it’s the turn of Firefox users to get equal treatment. According to Dr. Windows, going to the Skype landing page for browsers will finally let you use the communication platform’s functionality. There is still a warning that not all features might be available, but that might not actually be the case.

This compatibility with Firefox will be available on Skype 8.78, which is currently still in preview for Insiders. There’s no word yet on when it will roll out to the public, but until then, expect Skype’s official documentation to still believe that Firefox is the only browser that isn’t supported by Skype for Web.

All Galaxy S22 models to get Exynos 2200 and Snapdragon 898 variants

Published

on

Samsung is expected to soon announce what could be the biggest upgrade to its Exynos chips in years. The partnership it started with AMD a few years back is anticipated to level up the silicon’s graphics game, utilizing AMD’s rDNA technology for the benefit of mobile users. There has been some uncertainty, however, about which devices will be betting this Exynos 2200, especially with the ongoing chip shortage. The latest word gives a small amount of relief to would-be Galaxy S22 buyers, but the actual availability of this chip might still be in question.

Given recent controversies surrounding Samsung’s Exynos silicon, the arrival of the AMD-powered Exynos 2200 is naturally hoped to bring some much-needed salvation for the business. Early benchmarks look promising, at least under certain contexts and conditions, and the entry of graphics technology from AMD could spark a new area for competition among mobile chipset makers. Whether the Exynos 2200 lives up to expectation is, of course, a completely different question, but many are waiting with bated breath for what’s coming.

Unfortunately, present economic conditions might put a damper on that enthusiasm. Initially, there were doubts that Samsung would even put the Exynos 2200 inside its next smartphone flagship, reserving it for tablets or an ARM-powered Windows laptop. Eventually, rumors evolved to expect limited availability of Exynos-powered Galaxy S22 phones, probably exclusive to the Galaxy S22 Ultra.

Android Police’s Max Weinbach, however, gives a bit more hope by “confirming” that it will be available for all variants of the phone. The Galaxy S22, Galaxy S22+ (or Pro), and Galaxy S22 Ultra will get both Exynos 2200 and Snapdragon 898 versions, which, of course, still depend on the market.

Unfortunately, that latter might mean that those in the US won’t be seeing the graphics upgrade that the Exynos 2200 will promise. Buyers in the US have only been able to get Snapdragon-powered devices from Samsung, while European markets once had to contend with weaker Exynos chips only. It seems that tables will be turned and those in the US will feel short-changed when the Galaxy S22 arrives.
