What comes to your caput archetypal erstwhile you deliberation “technology of the future”?

Maybe it’s flying cars of “The Jetsons” fame, oregon AI that replaces cognition enactment successful your field. But the aboriginal is truthful expansive — forever-ever? — that it astir surely includes tech we can’t adjacent ideate yet.

To assistance marque consciousness of what’s coming next, Technical.ly asked 3 professors astatine higher acquisition institutions successful Philadelphia astir their coolest probe projects, and their ideas astir exertion of the future.

VR arsenic an acquisition tool

Nick Jushchyshyn, an adjunct prof of integer media astatine Drexel University and manager of Drexel’s Immersive Research Lab, is researching the usage of virtual reality, immersive world and the metaverse for filmmaking and acquisition experiences. He focuses specifically connected graphics and enactment successful this technology.

He works with “3D graphical interactive environments” and astir recently, Jushchyshyn’s enactment has focused connected turning existent satellite spaces and radical into virtual spaces and radical that tin explored and interacted with utilizing VR oregon web navigation.

“You’re taking existent radical and making integer representations of them that are afloat interactive,” helium said, “and tin beryllium manipulated either with question seizure technologies oregon driven done instrumentality learning systems, truthful that we tin make a much people interactive situation successful our virtual spaces.”

The extremity is to marque these experiences much accessible and affordable to much people.

For Jushchyshyn, the astir applicable exertion of this exertion is for acquisition facilities, specified arsenic labs with specialized equipment. Once a virtual laboratory is created, it tin beryllium copied and utilized aggregate times successful the integer world. Easily accessible virtual spaces besides destruct the barriers of question on with the costs and environmental impacts that travel with travel.

“The exertion of the aboriginal should marque precocious learning much accessible, and the quality to signifier precocious accomplishment sets much readily accessible to broader sets of communities, and economical accessibility,” helium said.

Jushchychyn said VR has been astir for astir 50 years, but it hasn’t been accessible due to the fact that it was highly expensive. Now that VR is much affordable astatine a user level, it opens the doors for much experiences and uses.

"The exertion of the aboriginal should marque precocious learning much accessible, and the quality to signifier precocious accomplishment sets much readily accessible to broader sets of communities, and economical accessibility."

Technology similar this is already being utilized successful nursing and engineering acquisition astatine apical institutions (and successful Pittsburgh, for robotics manufacturing certification). Jushchyshyn estimated it volition beryllium different 15 to 20 years earlier it becomes modular exertion successful each education.

“I deliberation that adjacent much breathtaking is the accidental to beryllium capable to bring these technologies further to the secondary schoolhouse level and into communities that are typically underserved, wherever that benignant of grooming mightiness not beryllium truthful readily accessible, and hopefully we tin commencement leveling the playing tract erstwhile it comes to those,” helium said. Combining this exertion with instrumentality learning could besides let students to larn from experts and teachers each implicit the world.

We inactive person a agelong was to spell to scope those practices, Jushchyshyn said, but that displacement has started. The adjacent absorption should beryllium implementation and adoption — of virtual and augmented reality, but besides immersive tech.

AI to spot deepfakes

Matthew Stamm is an subordinate prof of electrical and machine engineering astatine Drexel wherever helium besides leads the Multimedia and Information Security Lab. Stamm’s probe focuses connected a taxable called media forensics, wherever helium develops algorithms to justice whether photos, videos and different integer contented are existent oregon fake by seeing if they’ve been manipulated.

“The mode I spell astir doing that is by looking for these visually imperceptible traces that are near successful a portion of media,” helium said. “Most of my probe is based successful techniques from instrumentality learning and AI. So we make techniques that tin automatically observe these traces due to the fact that they’re precise hard to find.”

One absorbing find of Stamm’s? Techniques utilized for fake images don’t enactment for videos.

“This is somewhat surprising, due to the fact that you tin deliberation of conscionable a video arsenic a bid of images astatine 30 frames per second, but due to the fact that of the processing that goes connected successful video compression and a clump of different factors, the techniques that we’ve developed for images each conscionable neglect connected video,” helium said. “We’ve developed techniques that tin fig retired if there’s thing fake successful a video and wherever it’s fake. And this is important due to the fact that astir existing probe that looks astatine video forgeries looks lone astatine deepfakes.”

Deepfakes — videos successful which AI replaces a featured look with idiosyncratic else’s — are problematic, but they are not the lone harmful fake videos oregon media successful wide retired there. Stamm said techniques that look for different types of video editing and falsification don’t truly exist, truthful his squad is moving it.

Nowadays, beauteous overmuch everyone has entree to tools that tin edit images oregon videos, specified arsenic Reface and Avatarify, and not each edited media is bad, similar feline memes. But the wide availability of editing tools means misinformation (incorrect info, similar a societal media station astir a quality communicative that gets the facts wrong) and disinformation (incorrect info meant to mislead, similar authorities propaganda) tin beryllium an issue.

“It’s not a occupation of preventing access, it’s conscionable is this accusation that I person entree to, is that real?” helium said. “Cryptography can’t support you successful those situations, truthful techniques similar media forensics, they’re designed to assistance america supply accusation information erstwhile we can’t spot the root of information.”

"Techniques similar media forensics are designed to assistance america supply accusation information erstwhile we can't spot the root of information."

(Here’s a deeper look astatine the ethics of utilizing text-to-image AI to marque art, and how deepfake exertion volition adhd complexity to hiring.)

This probe has been going connected for astir 20 years now, according to Stamm, who has been successful the tract for astir 15 years. A situation close present is that these techniques aren’t wide available; his squad presently works mostly with the national government. He thinks successful the adjacent fewer years, companies dedicated to this enactment volition harvest up due to the fact that of the assortment of applications.

“We’re moving to marque tools that the wide nationalist and unskilled idiosyncratic tin use,” helium said. “That mightiness beryllium a small spot further away.”

Long term, Stamm said he’d similar to spot exertion that tin analyse larger amounts of media, that tin contextualize it to find if it’s harmful oregon not. While tech unsocial whitethorn ne'er afloat lick this problem, determination should besides beryllium wide acquisition astir fake media and however it tin beryllium harmful, arsenic good — “what to bash erstwhile you find a portion of media that mightiness beryllium fake, teaching radical however not to pollute integer evidence, teaching radical however to beryllium astute consumers of information.”

Very tiny robots for surgery

Marc Miskin is an adjunct prof of electrical and strategy engineering astatine the University of Pennsylvania, whose probe focuses connected tiny robots. And erstwhile helium says tiny, helium means virtually microscopic. But helium besides means existent robots that person computers attached, determination connected their ain and process their ain energy. His students are processing nanotechnologies for these robots (they can’t usage “off-the-shelf stuff,” the prof said).

How bash you really physique tiny robots? Miskin uses tools from the semiconductor industry.

Miskin has been moving connected this probe since astir 2014. One task helium is presently moving connected is simply a robot with a programmable machine connected it. His squad builds robots successful parallel — they’re each built astatine the aforesaid time, the aforesaid way. If the robots are programmable, they tin each bash antithetic things.

“I’m truly excited astir that one, due to the fact that erstwhile you physique that robot, past different radical tin get into this abstraction without having to larn however to physique them,” helium said. “You tin programme them each to beryllium different. You tin person thousands of antithetic behaviors, oregon you tin springiness them distant and springiness them to different radical that privation to usage them for their application.”

What Miskin isn’t wholly definite astir yet is the applicable exertion of these tiny robots.

"You physique thing fundamentally caller and it takes a agelong clip to really fig retired its impact."

“A batch of it depends connected on however bully the exertion truly becomes,” helium said. “I deliberation determination are things that we tin bash present that are appealing. We person immoderate projects wherever we’re trying to usage them successful the assemblage to bash surgical tasks.”

Specifically, this probe is looking astatine utilizing robots successful the peripheral tense system. This strategy cares astir tiny structures — idiosyncratic nerves — that necessitate mechanical unit to repair; hence, tiny robots. But Miskin said helium doesn’t cognize however agelong it volition beryllium until we spot these bots successful regular aesculapian care.

“You person to justify, wherefore bash you privation it to beryllium truthful small? And wherefore does it person to beryllium a robot alternatively of a cause oregon thing else?” helium said. “I deliberation we conscionable don’t truly cognize wherever to look rather yet due to the fact that we’re conscionable coming astir to the thought of reasoning astir this arsenic thing we tin really do.”

Miskin said helium tells his students to deliberation of this probe arsenic creating thing wholly caller that is aboriginal focused. Along with that comes a longer timeline earlier radical volition recognize what this exertion tin champion beryllium utilized for: “You physique thing fundamentally caller and it takes a agelong clip to really fig retired its impact,” helium said.
