WhatsApp project on misinformation during infectious disease outbreaks

Dr. Santosh Vijaykumar at Northumbria University's Department of Psychology is starting a project on how the chat service WhatsApp potentially spreads misinformation among elderly during infectious disease outbreaks. The research is funded by a WhatsApp Research Award for Social Science and Misinformation.

Public health agencies globally are facing a new challenge for managing the spread of Infectious Disease Outbreaks (IDO) – the parallel spread of rumours and misinformation via social media. WhatsApp played a significant role in this phenomenon during the May 2018 outbreak of the Nipah virus in South India, which claimed 17 lives, leaving health agencies struggling to manage public anxiety. Research on misinformation effects has shown that older adults are more vulnerable to misinformation compared to younger age groups. Diminishing cognitive abilities and memory recall limit their capacity to differentiate between various attributes of misinformation and original information, such as its source and authenticity.These problems can be exacerbated in a context like India where a confluence of cultural, religious and political norms can combine with misleading information resulting in competing narratives of the ‘truth’.

This project will examine WhatsApp as a ‘vector’ for the spread of misinformation about IDOs amongst older adults in South India, focusing on ‘forwards’- messages with original sources other than the sender (whether or not accompanied by a personal message). As part of this, it will analyse the information vulnerabilities associated with this age group, to inform strategies for combatting the problem. This study will be situated in the southern Indian city of Bangalore (Bengaluru), known as India’s IT hub, which has recently grappled with IDO scares including Nipah and H1N1.

Testing new technologies in modular housing with Home Group

Northumbria University is collaborating with Home Group, one of the biggest housing associations in the UK, in a new research project on independent living and modular housing.

In this project we will be testing a variety of new technologies, including wearable sensors and video communication. The goal is to explore the potential of future technologies that can support independent living, as well as the infrastructure that will be required. In the project, a multi-disciplinary team will explore the potential for providing digital technology support within modular housing to promote residents’ independence through monitoring connectivity and activity. Our programme of work will involve 4 monthly cycles of technology deployment and evaluation. This innovation and evaluation project will use mixed methods, involving analaysis of data from sensors, qualitative methods, including interviews and observational fieldwork.

The project is carried out in Home Group's Gateshead Innovation Village. In the Innovation Village, the company is testing a number of different modular housing approaches. With these new building techniques, it is possible to build an entire house in a factory and transport the finished structure to the building site, where it is assembled in a single day! Northumbria has been given access to a new modular home for one year, which will be used as a real-world testbed for the duration of the project, with a variety of end-users spending time and living on-site.

The project is led by Professor Glenda Cook from the Department of Nursing with Professor David Kirk (Computer and Information Science) and Professor Lars Erik Holmquist (Design).

Designing better money

What is the future of money? With widespread electronic payment systems and new and emerging financial technologies such as blockchain, the way we use money is going to change dramatically. We need to understand what the opportunities for improvements are - as well as some of the things we are at risk to lose.

Belen Barros Pena is carrying out her Ph.D. at Northumbria University in collaboration with Santander bank. It is funded by the Arts and Humanities Research Council and the National Productivity Investment Fund. In this post, Belen writes about her research with users of financial services and how it can help us to design better money. Contact her at

Designing better money

As part of my PhD, which I am doing in collaboration with Santander UK, I’ve spent the last few months trying to understand what is money. In this blog post, I will share some of the things I’ve learnt so far.

If you ask an economist what is money, they will tell you that money is three things: a unit of account, a medium of exchange and a store of value.

Money is a unit of account

That means money is a measure of value, but also that money is not just coins and notes. Money is an account, a data record, information stored on a ledger. In fact, the bulk of money in circulation, at least in the UK, is made not of cash, but of these information records.

Ledgers are interesting because they split monetary transactions into two parts: the value transacted, for example, £10; and the information about the transaction: who pays how much to whom.
This split between value transacted and transaction information does not happen when I pay with cash. When I give you a £10 note, what I am transferring to you is the value embodied in that note, and the transfer is instantaneous. The moment the note is in your hand, the value is yours, and it is no longer mine. That’s it: nothing else required. I don’t need to know who you are, you don’t need to know who I am, and unless you record the transaction somewhere, it will be forgotten about. Nobody will ever know that I paid you £10.

But when I pay you £10 using a debit card, you don’t get the value straight away. What we are actually doing is storing on a ledger the fact that I want to give you £10. And at some point in the near future, the payment infrastructure will read that data and transfer the actual value from me to you. But the information doesn’t disappear when the transaction is complete: who paid how much to whom will stay in the ledger, probably forever.

Money is a medium of exchange

That means money is used to pay for things. Some people argue that thinking about payments purely in terms of exchange hides their real nature. Payments are not just exchanges: payments are relationships. Relationships between people, the state, its financial laws and regulations, and the owners of the payment infrastructure: traditionally banks, but more and more telecommunications companies and mobile phone operators.

Money is a store of value

Finally, an economist will tell you that money is also a store of value. That’s why we save it.

Old, new money

Understood as these three things, money is old. Very old. It can be tracked to around 8,000 BC, born as a unit of account in Sumeria.

However, what we mostly understand as money today - currency that is the monopoly of a nation state - is actually quite young. In the UK it was born at the end of the 17th century with the creation of the Bank of England. In the US only in the second half of the 19th century. As early as the 1860s in the US there were still around 8000 currencies in circulation, issued by railway companies, shops, hotels and of course, by banks.

Then, in the 1960s, money started morphing again, first into plastic cards, and increasingly into a wave of our mobile phones.

The owners of the payment infrastructure, the banks and the mobile phone companies, are very enthusiastic about these new forms of money. They advertise these new moneys to us, praising their advantages, but also telling us that all forms of physical money, things like cheques and cash, are no good. Cheques are inefficient: they take a long time to settle, and require pesky humans to do so. Cash is dirty, and not just in the literal sense. After all, who goes around with suitcases full of cash? Who uses the 500 euro note? Cash, they tell us, is used mostly by people who are up to no good, for money laundering and tax evasion.

What they forget to mention is that physical forms of money, like cheques and cash, have some very good things going for them.

Exchanging at par

For example, cash is the only form of money that exchanges at par. If I give you a one euro coin, you get one euro. But if I pay you one euro with a debit card, you don’t get one euro: you get 98 cents. 1 euro minus the 2% transaction fee charged by the owner of the payment infrastructure. Great for them, not so good for you.


Physical forms of money impose constraints on us. Constraints are great things, and people use them in all sorts of interesting ways. If I am a bit short of money this month, I might leave my house on Saturday evening with a £20 note, so that I don’t overspend. When I run out of cash, I go home. And if I break my leg and I can’t leave my house, I can give £20 to my neighbour to get me some groceries. If the neighbour is a bit of a crook and runs away with the £20, that’s all I lose: £20.

This might sound funny to some of us, but for a lot of people, the ability to get others to financially transact on their behalf is critical. People homebound because of illness, disability, or good old age, delegate financial transactions to others. They get others to pay bills for them, to buy things for them, to withdraw cash for them.

With cheques and cash, because of the constraints built into them, they can manage the risk this entails and build trust on others progressively. If my neighbour runs away with a £20 note, that’s all I lose. But if I give my debit card and my PIN to my neighbour to get me some groceries, and my neighbour runs away with it … see what I mean?

New forms of money undermine our ability to manage risk when entrusting others with our finances. This is because their design assumes finances are personal, and they ignore the fact that, more often than not, our finances are communal.


The fact that cheques take time to settle also has certain advantages. The delay gives the person issuing the cheque a chance to get cold feet, to change their minds and cancel the transaction.

Have you ever heard people complaining about how Amazon’s 1-Click makes it too easy to spend money? That’s because they have removed all friction, without realising that friction, like those delays in cheques, has a role to play.

This idea of bringing friction back is becoming rather popular amongst banks, particularly in the context of protecting customers from financial scams.

Finally, cash is the only form of payment that allows us to remain anonymous. That’s because it is the only form of payment that does not split a transaction between its value and its information: cash is the only non-ledger form of payment we currently have. If only because of that, I believe it is worth preserving.

All the things we’ve lost

It looks like with our new fancy money forms we have lost a few things:
  • The ability to exchange at par.
  • The ability to manage our risk when trusting others with our finances.
  • The ability to change our minds about a payment.
  • The ability to remain anonymous.
Can we recover these things? Can we build them back into our new forms of money?

Designing better money

In the case of anonymity, it turns out that we can, as proven by Taler, a form of digital cash.

Like physical cash, Taler does not split transaction information from its value. When I pay you £10 with Taler, you get the value straight away.

There is a twist, though. With cash, the ability for the payee to remain anonymous is what makes tax evasion possible, so Taler removes that. Transactions guarantee the anonymity of the payer, but not of the person receiving the money. The payee must declare her payment income, making tax evasion hard. So Taler is cash, only better!

Taler demonstrates that it is possible to build some of the strengths of physical money, in this case anonymity, into our digital money. It also proves that digital platforms provide an opportunity to design better money.

What else can we do to improve our money? Can we build upon the strengths of physical forms of money to design better digital financial services? That’s the question our research is trying to answer.

Creating an interactive performance with Northern Dance

Northumbria University is collaborating with Northern Dance to develop a new project in which all media will be controlled by the movements of a single performer in real-time.

Northern Dance will lead a collaborative team combining art, technology and movement, to create a project, Ephemera, that showcases the Gesture and Media System (GAMS) tracking system, created by Moment Research.

This project is being developed at Northern Dance’s new renovated space in the Ouseburn. David Leonard the key driver and principal owner of the parent company Paper Dove, and is collaborating on the music for this project. Mike Chilton is the key player developing the artistic design of the project.  Dancer Maxine Fell, who trained at the Northern School of Contemporary Dance, will control all of the media with her movement. Alexander Gill, currently at the Royal Academy of Music, is designing music and soundscapes to work with the audio system. Steve Gibson from Northumbria School of Design is creating the interactive mapping for control of the media by the dancer, and collaborating on the music. The piece is being proposed to high-profile venues such as the Sage in Gateshead.

This project will create an interface that will allow users to interact with audio, video, lighting and Visual FX in real-time and will do so in a non-linear manner (i.e. allowing for different user experiences) without sacrificing rendering or playback quality. The project will be genuinely multi-disciplinary involving interaction design, dance, animation and Visual FX, and fine art. The key technological innovation will be enabled by the development of the GAMS motion-tracking system. In brief, this system uses infrared trackers (four are possible in the current configuration) and infrared cameras to track users in a space measuring up to 15x15 metres. A GUI-based software can be used to design space so that sound, video, animation, lights and Visual FX can be accessed at different spots in the room and manipulated by the movements of the user.

The lead partner, Paper Dove Company, is a design-led card publisher working with a range of major charities. Twenty years old, the company is majority owned by David Leonard, a graduate artist with an interest in bringing together art and technology in powerful and emotive ways. He has recently established a charitable company - Northern Dance - to make high-quality dance accessible to the public in the North East, keeping local talent in the region. The project is a partnership between Paper Dove Company (as lead) and Northumbria University providing technical development of GAMS. The project is supported by funding from Creativity Works (now Creative FUSE), with funds from the European Regional Development Fund.

Below is video documenting the initial results of the collaboration:

A new receptionist experience for PROTO

Northumbria University is collaborating with the PROTO Emerging Technologies Centre in Gateshead to develop a new remotely controlled reception system. VERS, a Virtual Embodied Reception System, was developed by Northumbria Ph.D. student Sam Nemeth under supervision of Professor Lars Erik Holmquist.

VERS is a system that lets a human receptionist greet visitors at multiple entrances. It consists of two parts:
  • A screen through which the receptionist can see the remote entrance, and communicate with visitors using voice
  • A screen at the entrance through which a visitor can see and communicate with the receptionist 
The screen that greets the visitor can be controlled by the receptionist to pan left and right, using a special-built interface. For instance, the remote receptionist can turn the screen to face the visitor, direct his or her vision to different areas such as the sign-in sheet, or physically indicate a direction. It also lets the users at either end maintain eye contact, which is very important to make the communication feel natural.

The VERS includes several unique purpose-built interfaces, including an ergonomically designed wooden ball to control the motion of the remote screen, and an old-fashioned "hotel bell" to attract attention for visitors.

VERS will be installed in PROTO and greet visitors for the first time at the official PROTO opening night on November 1!

Below is a short video showing some of the ways that a visitor and a receptionist can interact through VERS.
