A system that augments mixed reality visualizations using smartphones or tablets

Mixed reality (MR) and Augmented Reality (AR) technologies merge the real world with computer-generated elements, allowing users to interact with their surroundings in more engaging ways. In recent years, these technologies have enhanced education and specialized training in numerous fields, helping trainees to test their skills or make better sense of abstract concepts and data.

Researchers at University of Calgary have been trying to develop interfaces and systems that could enhanced MR visualizations. In a paper set to be presented at CHI 2023 LBW, they introduced HoloTouch, a system that can augment mixed reality graphics and charts using smartphones as physical proxies.

“To me, this paper was inspired for the most part by a work that I published during my final undergraduate year,” Neil Chulpongsatorn, one of the researchers who carried out the study, told Tech Xplore “They both originated from my interest in mixed reality interactions for data representations.”

Hacking phones remotely without touching via new inaudible ultrasound attack

The Near–Ultrasound Invisible Trojan, or NUIT, was developed by a team of researchers from the University of Texas at San Antonio and the University of Colorado Colorado Springs as a technique to secretly convey harmful orders to voice assistants on smartphones and smart speakers.

If you watch videos on YouTube on your smart TV, then that television must have a speaker, right? According to Guinevere Chen, associate professor and co-author of the NUIT article, “the sound of NUIT harmful orders will [be] inaudible, and it may attack your mobile phone as well as connect with your Google Assistant or Alexa devices.” “That may also happen in Zooms during meetings. During the meeting, if someone were to unmute themself, they would be able to implant the attack signal that would allow them to hack your phone, which was placed next to your computer.

The attack works by playing sounds close to but not exactly at ultrasonic frequencies, so they may still be replayed by off-the-shelf hardware, using a speaker, either the one already built into the target device or anything nearby. If the first malicious instruction is to mute the device’s answers, then subsequent actions, such as opening a door or disabling an alarm system, may be initiated without warning if the first command was to silence the device in the first place.

Android app from China executed 0-day exploit on millions of devices

Can you imagine if we had computer/brain interfaces what would happen? We’ll need brain firewalls and antivirus.


Android apps digitally signed by China’s third-biggest e-commerce company exploited a zero-day vulnerability that allowed them to surreptitiously take control of millions of end-user devices to steal personal data and install malicious apps, researchers from security firm Lookout have confirmed.

The malicious versions of the Pinduoduo app were available in third-party markets, which users in China and elsewhere rely on because the official Google Play market is off-limits or not easy to access. No malicious versions were found in Play or Apple’s App Store. Last Monday, TechCrunch reported that Pinduoduo was pulled from Play after Google discovered a malicious version of the app available elsewhere. TechCrunch reported the malicious apps available in third-party markets exploited several zero-days, vulnerabilities that are known or exploited before a vendor has a patch available.

Sophisticated attack

A preliminary analysis by Lookout found that at least two off-Play versions of Pinduoduo for Android exploited CVE-2023–20963, the tracking number for an Android vulnerability Google patched in updates that became available to end users two weeks ago. This privilege-escalation flaw, which was exploited prior to Google’s disclosure, allowed the app to perform operations with elevated privileges. The app used these privileges to download code from a developer-designated site and run it within a privileged environment.

Carbon nanotube transistors outperform silicon for first time ever

In a world first, a team of University of Wisconsin-Madison materials engineers have created carbon nanotube transistors that outperform state-of-the-art silicon transistors.

A big milestone for nanotechnology, this breakthrough could enable longer battery life, faster wireless communication and faster processing speeds for devices like smartphones and laptops.

The researchers reported their advance in a paper published Sept. 2, 2016, in the journal Science Advances. Read the open access paper here: http://advances.sciencemag.org/content/2/9/e1601240

The end of text-based passwords? ‘Transparent image moving’ provides a new solution

It’s past time the world moves away from text-based passwords and verifications for mobile phones and starts embracing more secure image-based solutions, say computer scientists from the University of Surrey.

In a new study, Surrey scientists demonstrate an image-based authentication system called TIM (Transparent Image Moving) for mobile phones to help reduce the risk of shoulder surfing attacks. TIM requires users to select and move predefined images to a designated position for passing authentication checks, similar to those required for .

The proof-of-concept study found that 85% of TIM users believed it could help them to prevent password guessing and shoulder surfing attacks. The study also found that 71% of participants think TIM is a more usable image-based solution than others on the market. The research has been published in the Journal of Information Security and Applications.

‘Inkable’ nanomaterial promises big benefits for bendable electronics

An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight and bendable displays and devices.

The material, , could be incorporated into many components of future technologies including mobile phones and computers, thanks to its versatility and recent advances in nanotechnology, according to the team.

RMIT University’s Associate Professor Enrico Della Gaspera and Dr. Joel van Embden led a team of global experts to review production strategies, capabilities and potential applications of zinc oxide nanocrystals in the journal Chemical Reviews.

FCC agrees on a new framework for satellite coverage for smartphones

The framework will enable satellite access for smartphone users in emergency situations.

The Federal Communications Commission (FCC) intends to establish a new regulatory framework to enable connections between satellite operators and wireless firms to connect smartphone users in isolated or underserved regions worldwide.

FCC stated in a release that it aims to “create clear and open protocols to facilitate supplemental coverage from space.”

Nvidia GTC Highlights The Physical Side Of AI

ChatGPT launched a tide wave of interest in AI. For many consumers, AI is finally living up to long overdue expectations. The accomplishments of ChatGPT in a short period of time are phenomenal. But what is yet to come when AI is combined with robotics will change everything.

I have been promoting the advances in robotics for several years. I even called 2022 the year of robotics, partially because of the growing need to overcome shortages in labor and to handle tasks beyond the physical or mental capability of humans, and partially because of the continued advances that AI, accelerated processing, semiconductor, sensors, wireless connectivity, and software technologies are enabling to develop advanced, autonomous machines. Robots are no longer just for the manufacturing floor. They are hazardous material handlers, janitors, personal assistants, food preparers, food deliverers, security guards, and even surgeons that are increasingly autonomous. Essentially, they are AI in the physical world. As a result, robot competitions are heating up from middle schools to Las Vegas.

As seen at CES, robotics technology is advancing rapidly with advances in technology. My favorite examples were the multi-configurable Yarbo outdoor robot and the John Deere See & Spray. Yarbo can be a mower, a leaf blower, or a snow blower. If it could dispose of animal excrement and the annoying neighbor, it would be perfect yard tool. On the other end of the spectrum was the John Deere See & Spray Ultimate, a tractor with up to a 120-foot (36.6m) reach that uses AI/ML to detect weeds smaller than the size of a smart phone camera and spray herbicide accordingly. John Deere also offers self-drive tractors.
