These Researchers Want to Send Smells Over the Internet – Electrical stimulation of cells in the nasal passages produces sweet fragrances and chemical odors
A volunteer tries out a "digital smell" apparatus
Electrical stimulation of neurons high up in the nasal passages can cause people to perceive aromas that aren’t really there.

 

Imagine a virtual reality movie about the Civil War where you can smell the smoke from the soldiers’ rifles. Or an online dating site where the profiles are scented with perfume or cologne. Or an augmented reality app that lets you point your phone at a restaurant menu and sample the aroma of each dish.

The researchers who are working on “digital smell” are still a very long way from such applications—in part because their technology’s form factor leaves something to be desired. Right now, catching a whiff of the future means sticking a cable up your nose, so electrodes can make contact with neurons deep in the nasal passages. But they’ve got some ideas for improvements.

This digital smell research is led by Kasun Karunanayaka, a senior research fellow at the Imagineering Institute in Malaysia. He started the project as a Ph.D. student with Adrian Cheok, now director of the institute and a professor at the City University of London, who’s on a quest to create a “multisensory Internet.” In one of Cheok’s earliest projects he sent hugs to chickens, and his students have also worked with digital kisses and electric taste.

 

Karunanayaka says most prior experiments with digital smell have involved chemical cartridges in devices that attach to computers or phones; sending a command to the device triggers the release of substances, which mix together to produce an odor.

Working in that chemical realm, Karunanayaka’s team is collaborating with a Japanese startup called Scentee that he says is developing “the world’s first smartphone gadget that can produce smell sensations.” They’re working together on a Scentee app that integrates with other apps to add smells to various smartphone functions. For example, the app could link to your morning alarm to get the day started with the smell of coffee, or could add fragrances to texts so that messages from different friends come with distinct aromas.

But Karunanayaka’s team wanted to find an alternative to chemical devices with cartridges that require refilling. They wanted to send smells with electricity alone.

For his experiments, he convinced 31 volunteers to let him stick a thin and flexible cable up their noses. The cable was tipped with both a tiny camera and silver electrodes at its tip. The camera helped researchers navigate the nasal passages, enabling them to bring the electrodes into contact with olfactory epithelium cells that lie about 7 centimeters above and behind the nostrils. These cells send information up the olfactory nerve to the brain.

Typically, these olfactory cells are stimulated by chemical compounds that bind to cell receptors. Instead, Karunanayaka’s team zapped them with an electric current.

The researchers had previously combed the scientific literature [PDF] for examples of electrical stimulation of nasal cells, and found some reports that the stimulation caused test subjects to perceive odors. So they decided to experiment with different parameters of stimulation, altering both the amount and frequency of the current, until they found the settings that most reliably produced smell sensations.

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.

This experiment was a very basic proof-of-concept, Karunanayaka says. The next step is to determine whether certain stimulation parameters are reliably linked to certain smells. He must also investigate how much variability there is between subjects. “There may be differences due to age, gender, and human anatomy,” he says.

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.”

 

The digital smell experiment setup

 

Two possible solutions suggest themselves, Karunanayaka says: They could make the insert smaller, more flexible, and less unbearable. Or they could skip past the nose’s olfactory cells and directly stimulate the brain.

As a step toward that neurotech goal, the Imagineering Institute researchers are planning a brain-scanning collaboration with Thomas Hummel, a leading expert in smell disorders at the Technische Universität Dresden in Germany. In the planned experiment, volunteers will both smell real odiferous objects, such as a rose, and also receive nasal stimulation. All these sniffs will take place while the volunteers are getting their brains scanned by a noninvasive method such as fMRI.

“We’ll see which areas in the brain are activated in each condition, and then compare the two patterns of activity,” Karunanayaka says. “Are they activating the same areas of the brain?” If so, that brain region could become the target for future research. Maybe the researchers could use a headset that provides a noninvasive form of stimulation to trigger that brain region, thus producing smell sensations without the need for either a rose or a nose-cable.

Such tech could serve a restorative purpose: People with smell disorders could theoretically wear some headgear to regain some smell functions. And for people with intact sniffer systems, it could provide enhancements: For example, VR headset makers could build in the brain-stimulating tech to provide users with a more immersive and richer sensory experience.

Hiroshi Ishiguro

Hiroshi Ishiguro received a D. Eng. in systems engineering from Osaka University in 1991. He is currently Professor of the Department of Systems Innovation in the Graduate School of Engineering Science at Osaka University (2009-) and  Distinguished Professor of Osaka University (2017-). He is also visiting Director (2014-)  and group leader: (2002-2013) of Hiroshi Ishiguro Laboratories at the Advanced Telecommunications Research Institute, and an ATR fellow. His research interests include sensor networks, interactive robotics, and android science.

Professor Ishiguro is director of the Intelligent Robotics Laboratory, part of the Department of Systems Innovation in the Graduate School of Engineering Science at Osaka University. A notable development of the laboratory is the Actroid, a humanoid robot with lifelike appearance and visible behaviour such as facial movements.

In robot development Ishiguro concentrates on the idea of making a robot that is as similar as possible to a live human being; at the unveiling in July 2005 of the female android named Repliee Q1Expo, he was quoted as saying “I have developed many robots before, but I soon realised the importance of its appearance. A human-like appearance gives a robot a strong feeling of presence. … Repliee Q1Expo can interact with people. It can respond to people touching it. It’s very satisfying, although we obviously have a long way to go yet. In his opinion” it may be possible to build an android that is indistinguishable from a human, at least during a brief encounter.”

Ishiguro has created an android that resembles him, called the Geminoid. The Geminoid was among the robots featured by James May in his 5 October 2008 BBC2 documentary on robots Man-Machine in the TV series Big Ideas. He also introduced a telecommunication robot called the Telenoid R1. Hiroshi also uses his android to teach his classes at Osaka University and he likes to scare his students by making the Geminoid perform human-like movements such as blinking, “breathing” and fidgeting with his hands. Ishiguro has been listed as one of the 15 Asian Scientists To Watch by Asian Scientist Magazine on 15 May 2011.  In the 2018 documentary on artificial intelligence – Do You Trust This Computer? – Professor Ishiguro is interviewed and is seen interacting with one of his robots.

 

David Levy

David Levy studied Pure Mathematics, Statistics, and Physics at St. Andrews University, Scotland, from where he graduated with a B.Sc. degree. He taught practical classes in computer programming at the Computer Science Department of Glasgow University, before moving into the world of business and professional chess playing and writing. (He wrote more than thirty books on chess.) He was selected to play for Scotland in six World Student Team Chess Championships (1965-1970) and in six Chess Olympiads (1968-1978). In 1968 and 1975 he won the Scottish Chess Championship. He was awarded the International Master title by FIDE, the World Chess Federation, in 1969, and the International Arbiter title in 1976.

The development of David’s interest in Artificial Intelligence started with computer chess, which was a logical combination of his addiction to chess and his work in the field of computing. In 1968 he started a bet with four Artificial Intelligence professors, including John McCarthy who in 1955 had coined the phrase “Artificial Intelligence”, that he would not lose a chess match against a computer program within ten years. He won that bet, and another one for a further five years, succumbing only twenty-one years after making the first bet, and then to a forerunner of the program that defeated Garry Kasparov in 1997. David was first elected President of the International Computer Chess Association (ICCA) in 1986, and after a gap from 1992 to 1999 was elected once again, a position he has held since then (the association now being named the International Computer Games Association (ICGA)).

Since 1977 David has led the development of more than 100 chess playing and other microprocessor-based programs for consumer electronic products. He still works in this field, leading a small team of developers based mainly in the UK.

David’s interest in Artificial Intelligence expanded beyond computer games into other areas of AI, including human-computer conversation. In 1994 he brought together a team to investigate pragmatic solutions to the problem, resulting in his winning the Loebner Prize competition in New York in 1997. He won the prize again in 2009.

David’s achievements in the associated field of Social Robotics include founding international conferences on the subject, and being a co-organizer of six such conferences between 2007 and 2017. He has published a primer on A.I., Robots Unlimited. His fiftieth book, Love and Sex with Robots, was published in November 2007, shortly after he was awarded a PhD by the University of Maastricht for his thesis entitled Intimate Relationships with Artificial Partners.

David has had a lifelong interest in organising mind sports events, and was one of the organisers of the World Chess Championship matches in London (1986 and 1993), as well as the World Checkers Championship match between the human champion and a computer program (1992 in London and 1994 in Boston), in addition to dozens of computer chess championships and similar events. In 1989 he inaugurated the Computer Olympiad, for competitions between computer programs playing thinking games, which has since become an annual event. David also created the Mind Sports Olympiad, in which human players compete at more than 30 different strategy games and other “mind sports”.

His hobbies include classical music, and he has recently started playing chess again after a long gap away from active play.  He lives in London with his wife and their cat.

Yorick Wilks (Senior Research Scientist)

 

Professor . Yorick Wilks is a Senior Research Scientist at the Institute for Human and Machine Cognition (IHMC), Professor of Artificial Intelligence at the University of Sheffield, and Senior Research Fellow at the Oxford Internet Institute at Balliol College.

He studied math and philosophy at Cambridge, was a researcher at the Stanford AI Laboratory, and was Professor of Computer Science and Linguistics at the University of Essex. Following this, he moved back to the United States for ten years to run a successful, AI laboratory in New Mexico—the Computing Research Laboratory (CRL)—established by the state of New Mexico as a center of excellence in AI in 1985. His own research group at CRL was rated among the top five in the US in its area by the lab’s International Advisory Board, and it became totally self-supporting with grants by 1990.

In 1993 he took up a chair of AI at the University of Sheffield, and became founding Director of the Institute of Language, Speech and Hearing (ILASH). Since then he has raised over $50 million in grants from UK research councils and the European Community, and the Sheffield Natural Language Processing Research Group constitutes a major UK group in the area.

Professor Wilks has led numerous UK, US and EC initiatives, including the UK-government funded Interdisciplinary Research Centre AKT (2000-2006) on active knowledge structures on the web (www. aktors.org). He has published numerous articles and nine AI books, including “Electric Words: dictionaries, computers and meanings” (1996 with Brian Slator and Louise Guthrie) and “Machine Translation: its scope and limits,” in 2008. His most recent book is “Close Encounters with Artificial Companions” (2010).

He is a Fellow of the American and European Associations for Artificial Intelligence and on the boards of some fifteen AI-related journals. He designed CONVERSE, a dialogue system that won the Loebner prize in New York in 1997, and he was the founding Coordinator of the EU 6th Framework COMPANIONS project on conversational assistants. A Companion keeps track of detailed knowledge of its owner as well as the wider world; its current major implementation is as an elicitor and organizer of personal knowledge and digital records, but the general concept is being adapted to learning, health and travel environments. His Companion-based work continues at IHMC as a part of the Tampa VA Smart Home initiative.

In 2008 Dr. Wilks was awarded the Zampolli Prize at the International Conference on Language Resources and Evaluation (LREC-08) in Marrakech, and the Association for Computational Linguistics (ACL) Lifetime Achievement Award at ACL-08 in Columbus, Ohio.

William Yeager

William “Bill” Yeager is an American engineer. He is best known for being the inventor of a packet-switched, “Ships in the Night,” multiple-protocol router in 1981, during his 20-year tenure at Stanford’s Knowledge Systems Laboratory and the Stanford University Computer Science department. The code was licensed by upstart Cisco Systems in 1987 and comprised the core of the first Cisco IOS.

He is also known for his role in the creation of the IMAP mail protocol. In 1984 he conceived of a client/server protocol, designed its functionality, applied for and received the grant money for its implementation. In 1985 Mark Crispin was hired to work with Bill on what became the IMAP protocol. Along with Mark, who implemented the protocols details and wrote the first client, MMD, Bill wrote the first Unix IMAP server. Bill later implemented MacMM which was the first MacIntosh IMAP client. Frank Gilmurray assisted with the initial part of this implementation.

At Stanford in 1979 Bill wrote the ttyftp serial line file transfer program, which was developed into the MacIntosh version of the Kermit protocol at Columbia University. He was initially hired in August 1975 as a member of Dr. Elliott Levanthal’s Instrumentation Research Laboratory. There, he was responsible for a small computer laboratory for biomedical applications of mass spectrometry. This laboratory, in conjunction with several chemists and the Department of inherited rare diseases in the medical school, made significant inroads in identifying inherited rare diseases from the gas chromatograph, mass spectrometer data generated from blood and urine samples of sick children. His significant accomplishment was to complete a prototype program initiated by Dr. R. Geoff Dromey called CLEANUP. This program “extracted representative spectra from GC/MS data,” and was later used by the EPA to detect water pollutants.

From 1970 to 1975 he worked at NASA Ames Research Center where he wrote, as a part of the Pioneer 10/11 mission control operating system, both the telemetry monitoring and real time display of the images of Jupiter. After his tenure at Stanford he worked for 10 years at Sun Microsystems.

At Sun as the CTO of Project JXTA he filed 40 US Patents, and along with Rita Yu Chen, designed and implemented the JXTA security solutions. As Chief Scientist at Peerouette, Inc., he filed 2 US and 2 European Union Patents. He has so far been granted 20 US Patents 4 of which are on the SIMS High Performance Email Servers which he invented and with a small team of engineers implemented, and 16 on P2P and distributed computing. In the Summer of 1999 under the guidance of Greg Papadopoulos, Sun’s CTO, and reporting directly to Carl Cargill, Sun’s director of corporate standards, he led Sun’s WAP Forum team with the major objective, “… to work with the WAP Forum on the convergence of the WAP protocol suite with IETF, W3C and Java standards.”

Bill received his bachelor’s degree in mathematics from the University of California, Berkeley in 1964; his master’s degree in mathematics from San Jose State University, San Jose, California, in 1966; and completed his doctoral course work at the University of Washington in Seattle, Washington in 1970. Then decided to abandon mathematics for a career in software engineering and research to the skepticism of his thesis advisor because Bill thought the future was in computing.
