Email Charter
We can help reverse the problems caused by email overload. Be part of the solution.
1. Respect recipients’ time
Make your email easy to read: use these plain English tips to save others time AND make your communication more effective.
2. Short is not rude
It’s ok to be brief. Don’t take brevity personally and know that others won’t. Wordy responses take longer to read. People will scan it and are less likely to read it all; key details can be easily missed.
3. Celebrate clarity
Subject line: write a short subject line that clearly gives the topic.
Opening line: make it the basic reason for writing.
4. Slash CCs
Only CC someone who really needs this message. Don’t thoughtlessly ‘Reply all’: choose individual recipients.
5. Tighten the thread
If you need to include the email trail showing the context, cut what’s not relevant. If it’s long, summarise or make a phone call instead.
6. Reduce attachments
Don’t use images like logos in your signature – they’ll be attached and I’ll try to open it in case it’s something relevant.
7. Should we expect an instant response?
Don’t feel you need to give an instant response, and don’t expect to get one. Skype or the telephone are your tools if something is urgent.
8. Disconnect sometimes
Can you calendar half-days for email-free working? And you should be having email-free evenings, weekends, holidays. Have an ‘auto-response’ that makes it clear you’re not checking.
9. Reference this charter
Spread the word and help change email culture. Reference this charter in your email footer.

COVID Ward
A blogpost by Emma Holliday, student on MSc HCI 2019-2021
Getting into the video games industry was originally my inspiration for studying Computer Science. As I learned about the often toxic work environments (and sexism) in the gaming industry, I decided to leave this dream behind and went into software development instead. Thatâs why Iâm so amazed and thrilled to have actually designed and built my own game and, even better, to have won an award for it.
Click here to play the game! Spoilers below!
The game itself was built as part of my coursework for the Serious and Persuasive Games module (led by Prof Anna Cox) on the Human-Computer Interaction course at UCL. (Even though I had somewhat given up on a career in the gaming industry, I still really loved games and would take any excuse to learn about them and play them.) Something that really stood out to me during the lectures was the concept of the âMagic Circleâ, an idea that games exist within set boundaries that are separate to the real world. This means that different rules apply within game (e.g. violence is allowed), actions in the game donât have consequences in the real world, and actions in the real world donât apply to the game. I immediately challenged this â Iâm sure weâve all had that gaming session that left friendships a little sour even after the game had finished, learnt something new or even strengthened our relationships. I personally believe, particularly with narrative-based games, it is very unlikely to not leave some lasting impression in the real world long after the game has been played. As such, I designed a game that would exploit breaking the âMagic Circleâ by including peopleâs real-world actions into gameplay. My hopes were that, by breaking the âMagic Circleâ upfront, this would weaken the boundaries between the game and the real world, encouraging players to take experiences from the game back into real life.
My time studying this module was during the COVID-19 pandemic which also provided a lot of inspiration, largely because it was inescapable and incredibly topical. Other games which we studied during the module were also influential, particularly those on blame culture in nursing (such as Nurseâs Dilemma and Patient Panic). All of this culminated in my game, COVID Ward, where players take on the role of a nurse working in the intensive care unit during the COVID-19 pandemic. The gameplay is quite simple, players use arrow keys to control the nurse and spacebar to administer aid to patients in the ward. Patient health deteriorates over time and they will eventually die if their health becomes too low while fully healed patients are able to leave the ward. The game plays out as levels representing 12 hour shifts, so time is limited and the nurse character can only do so much in a day. In between levels is where the âMagic Circleâ is broken; the player is asked a question relating to their real-world actions during the pandemic and their answer affects the number of patients admitted to the ward during the next level. For example, the question may ask if the player always wore a mask while on public transport. If the player answers ânoâ, there would be more patients in the ward the next day than if they had answered âyesâ. Through this, players see the their actions directly associated with the effects on other people and healthcare staff.
The game was refined iteratively thanks to playtesting with my friends, fellow students, and staff on the Serious and Persuasive Games course. Finally, a user study was completed to test if the game had the desired effects of making people feel more responsible for their actions, encouraging them to follow COVID-19 safety guidance more closely and increasing empathy for nursing staff. Though it was a small scale study, initial results were very positive and suggested that the game had achieved its goal in terms of attitude change. Qualitative responses from participants repeatedly mentioned the use of their real world actions and suggested it was both engaging and encouraged them to reflect more deeply on their actions. As such, breaking the âMagic Circleâ is a promising technique for persuasive games which warrants further research.
In terms of development, the game was built using Game Salad (a no-code game authoring tool). Though Iâm familiar with code, (and there were times I wished I was using code!) GameSalad did provide a really quick way to get started and put ideas together without too much learning overhead. Having since tried to pick up Unity, I can say Game Salad is definitely a lot quicker to get your ideas into something working, which is crucial for iterative development. Game Salad also made it very easy to publish my game so that others could play it online, which helped enormously when getting feedback and conducting the user study as there was no installation or downloads required.
In an early version of the game, everything was represented by incredibly simple shapes and numbers. While I support the concept of primarily using the mechanic to deliver the message, as demonstrated remarkably in Brenda Romeroâs games, I felt my game would benefit from graphics and sound effects to help immerse the player and reinforce the narrative that these were real people affected by their actions, encouraging stronger empathy. Given the short time frame (and that I am only one person who is not talented enough to do everything from scratch!) I was exceedingly grateful for assets created by other artists which allowed me to create something that was much more complete than I could have achieved on my own. I found the music by Bio_Unit on Free Music Archive and got sound effects from Kenney.nl (a fantastic source for several free assets!) I paid for some pixel-art assets from Malibu Darby through Humble Bundle which, very fortunately, had a game dev bundle just as I was building the game. I also dabbled in editing the pixel art myself to customise it to my game. If youâd like to give that a go, I recommend aseprite.
Overall, I was really happy with my game and the results of the user study. Prof. Anna Cox had suggested that the class submit their work to the CHI PLAY student game competition. Earlier in my time at UCL, Prof. Catherine Holloway had encouraged us to always try and share our work with the academic community and introduced me to Student Research Competitions. These are often held across different ACM conferences (such as SIGCHI, SIGACCESS, CHIPLAY) and felt much more approachable to me as the level of work expected was closer to what I had already done for my coursework. As such, I decided to go for it and submit my game and a paper detailing the user study to CHI PLAY 2021âs Student Game Design Competition. I didnât really expect to win anything, but I was just happy to share my game in the hopes it might have a life beyond my university coursework grades.
So I was very excited when I heard back to find out my game had been accepted! It turns out, 8 of the 19 submissions were accepted to the conference as finalists. This did mean, however, that I had a bit more work to do! I updated my paper to respond to the reviewersâ comments, battled with the proper formatting and TAPS submission system (though the support staff are really helpful), and created a reaction video to be played at the conference. Iâd be lying if I said it wasnât stressful (largely because it fell right across the deadline for my final MSc dissertation!!) but it was definitely worth it to see my work presented at the conference and all the interest it generated. Even more so when I was announced as receiving an honourable mention for the competition! I also got to attend the entire conference â though you donât have to be an author to do so â and joined lots of interesting talks and presentations across all aspects of games.
It was really rewarding finding myself back in the games industry, in a sense, but from a completely different direction than I had ever imagined and one that was much better suited to me and my passions. It was even more rewarding to know that I had contributed to it and that, maybe one day, my research will have an impact on the games I end up playing on my sofa.

Every wondered how to get someone to reply to your email?
Me this week: why is this guy chasing me for a reply today when he only emailed me on Thursday?
Also me this week: how come that person I emailed on Wednesday last week STILL hasn’t replied?
We’ve all spent time hitting the refresh button on an inbox waiting for a reply to an email we’ve sent and wondering what’s holding things up. The truth is, people send urgent emails before others and if they think a reply to your email is not urgent and is going to take them ages to write, you might be waiting a really long time!
Our frustration waiting for others to reply to our emails led us to investigate which factors influence how quickly people respond to emails and whether there’s anything we can do as a sender to get them to choose to reply to us before answering someone else’s message!The results of our study of 45 people responding to 16,200 e-mails sent over a 3 week period show that when e-mail replies are not urgent, people wait to a later time to send replies rather than responding immediately. However, when they do respond they are more likely to tackle the messages that are easier to respond to (eg needing a short reply) and those that carry the greatest importance (eg when there’s something in it for the sender). In contrast, when presented with e-mails that need an urgent reply, people prioritize these and disregard factors such as length of reply.
Our results are important for all of us who use e-mail and want timely responses. Composing e-mails that clearly signal that an urgent response is needed is the best way to ensure that the receiver will deal with it promptly. If it’s not urgent, making clear that you just need a short response will mean your email gets replied to before others.

How did people respond to the disruption to work caused by the pandemic?
Our paper “The new normals of work: a framework for understanding responses to disruptions created by new futures of work” has just come out in Human-Computer Interaction Journal.
Open access to the paper is available here: https://www.tandfonline.com/doi/full/10.1080/07370024.2021.1982391
In the paper, we explore how people adapted to work during the pandemic and how we might understand people’s response to disruption in the new future of work. We highlight a number of issues, tools and strategies that people used in their work to support them while working remotely. For example, virtual commutes, having dedicated space, new scheduling techniques or staying connected with colleagues through virtual chats and async chatsÂ
Exploring these with the Genuis and Bronstein model of “new normal” we show 3 kinds of responses:
- waiting to return to old normal,
- finding a new normal and
- anticipating a new future of work.
These new normals of work help us to understand how we can help workers going forward.
We’d like to thank our reviewers for their feedback and our participants for helping develop our work within eworklife.co.uk and a special shoutout to @DilishaBP whose work with the new normal model inspired this work đ You can find their paper on Finding a “New Normal” for Men Experiencing Fertility Issues here: dl.acm.org/doi/abs/10.114âŚ

CHI 2021 – a blog post by Shiping Chen
When the Social Becomes Non-Human
Have you ever interacted with non-humans? A team of researchers from the University of Oslo and the SINTEF examined how young people perceive various types of social support provided by chatbots. Their results indicate that chatbots can be a daily source of social support for young people, helping them think about themselves more constructively, and stimulating self-disclosure without social judgment by offering a safe and anonymous space for conversation.
Read the research paper here: https://dl.acm.org/doi/10.1145/3411764.3445318
Young people are increasingly suffering from mental health issues, but they tend not to seek out professional help. Despite needing social support, young people often struggle to reach out to others. This problem has become more acute during the COVID-19 pandemic. Unexpected changes to professional and personal lives have placed a burden on peopleâs mental health. Pandemic-related restrictions such as lockdowns and social distancing have made it more difficult to receive in-person support from friends and professionals. As a result of all this, we now urgently need effective online tools that can provide people with the social support they need.
Chatbots, especially those designed for social and mental health support (social chatbots, or emotionally aware chatbots), can help meet these demands. As artificial agents, chatbots interact with users through natural language dialogue (text, speech, or both). Social chatbots, such as Replika, Woebot, and Mitusuku, imitate conversations with friends, partners, therapists, or family members to be humanlike, with the potential to perceive, integrate, understand, and express emotions.
Other online channels (e.g., Instagram, Facebook, online groups, and health forums, etc.) can also provide social support to young people, however they carry certain limitations such as the risk of receiving inaccurate guidance or the possibility of not receiving help from others despite reaching out.
The researchers conducted in-depth interviews with sixteen young people aging from 16-25 years old. They found that after using Woebot for two weeks, most participants reported that the chatbot provided appraisal support and informational support; around half of them received emotional support; and some received perceived instrumental support.
- Appraisal support: Support offered in the form of feedback, social comparison, and affirmation.
- Emotional support: Expressions of empathy, love, trust, and caring.
- Informational support: Advice, suggestions, and information given by the chatbot to help the user solve a problem.
- Instrumental support: Tangible aid, which is characterized by the provision of resources in offering help or assistance in a tangible and/or physical way, such as providing money or people.
So more specifically, what did the sixteen young peopleâs find was good about these chatbots? First of all, as a non-human agent, the conversational chatbot can make people feel like they are writing a diary entry or speaking in a way to themselves, thereby facilitating self-reflection, and making self-disclosure easier, safer, and more honest. Using chatbot for social and emotional support is also thought to be more reliable than talking to a human, as well as being a good choice for discussing worries that are more personal or private.
As artificial agents, chatbots can easily provide users with lots of relevant, immediate, and efficient information, without being constrained by time or space. This may be useful when our worries extend beyond the scope of our friendsâ knowledge or expertise. Moreover, different sources of support can act collaboratively, as the chatbot Woebot was reported to motivate users to contact others for help as well as guiding people in their search for information, which indicates that a chatbot may have the potential to help solve practical problems.
However, despite the many positive comments from users, using current chatbots for social support is not a perfect solution. Current chatbots may have biases, or inadequate or failed responses, affecting the quality of the user experience. Psychologically, getting support from others makes some people feel âcared for and lovedâ, which is not the case when receiving response from a chatbot, as some may see chatbots as merely robots and not emotional. People who need chatbots as a source of support, may need time to develop relationships, become familiar with and develop trust towards chatbots. Through conversations about personal stories, userâs private data is collected and stored in chatbots. Ensuring usersâ privacy and maintaining a relationship of trust is another challenge.
Indeed, chatbots provide us with a new way to get connected and supported besides the traditional human-human context. It could be further evaluated and studied in a larger sample and different user groups. This brings further questions about how chatbots for social support may influence the future of human communication. Imagine the future – when one day chatbots can provide social support like real people. What will be the human-human relationship at that time? When we have another place (chatbots) to talk about our distress or happiness, how will it affect our interpersonal relationships?

How AI is helping us connect in digital spaces
With the COVID-19 pandemic resulting in stringent social restrictions around the world, I was fascinated by how individuals (including myself) adapted to our newfound situation. Living in a new reality where I could not meet up with friends and family, I, like others, turned to social technologies to satiate my need for connection. However, with all other social affordance stripped away, I was left unsatisfied with the current capabilities of online socialising. Online messaging and video-calling did not seem to satisfy my social cravings. At times, it was dry, awkward, and overwhelming. It truly took a pandemic to realise the deficiencies of digital devices in emulating the deep, rich, exciting (and often messy) offline interactions we took for granted in our pre-pandemic life.
Therefore, as the CHI 2021 conference came around, I was excited to see what new research was being undertaken to make the online socialising experience more meaningful. As I scoured the programme, favouriting talks relating to online communication, social media, etc., I noticed that two studies incorporated artificial intelligence (AI) to help make online interactions more affect sensitive through âAI-mediated communicationâ. âAffectâ refers to the psychological common-denominator of our emotional lives, underpinning emotions, moods, feelings, etc. (Russell, 2003). So how were researchers leveraging AI to help make our online interactions more affective, and should they be?
The first study by Murali et al. (2021) titled: AffectiveSpotlight: Facilitating the Communication of Affective Responses from Audience Members during Online Presentations, developed and investigated the efficacy of a Microsoft Teams embedded affect-sensitive AI-bot (named AffectiveSpotlight). The study aimed to address the problem of limited audience-presenter interaction during online presentations by implementing AffectiveSpotlight which was able to capture and communicate the affective responses from the audience to the presenter. The bot would analyse emotive responses (valued by presenters) of each audience member in real-time and spotlight the most expressive to the presenter without labelling the emotion; allowing the presenter to interpret it themselves. The study found that usage of AffectiveSpotlight improved the presenterâs experience: making them feel more aware of their audience, speak for longer periods (implying reduced speaker anxiety), and also led to self-rating of their presentation quality that was closer to audience members responses. Whilst these were promising results, participants were solely from the tech sector, limiting the overall generalisability of findings to other social groups who also perform online presentations e.g., teacher-student interactions.
The second study by Liu et al. (2021) titled: Significant Otter: Understanding the Role of Biosignals in Communication, explored the usage of a smartwatch-based AI software (named Significant Otter) that analysed users bio-signals (heart rate) to generate a set of possible emotional states that the user could choose from and send to their romantic partner via animated otters. The qualitative study followed romantic couples for over a month to investigate the role of Significant Otterâs bio-signal sharing capability in communication. Couples reported that the ability to share bio-signals in this manner supported easier, authentic communication and nurtured a greater sense of social connection. These were exciting results; however, the paper did mention how some participants questioned themselves when the presented possible emotional states did not match what they felt internally. Also, other participants would blindly accept Significant Otters suggestions leading them to reflect less on their actual state.
These papers fascinated me; I had never thought that AI could help close the emotional gap between individuals in digital space, and how this helped to facilitate richer online interactions. Research into affect-sensitive AI is integral to the HCI field of affective computing. There have been past calls in this field to frame affect not as discrete units of information to be processed by a computer (affect as information), but as dynamic, socio-culturally embedded outcomes experienced through interaction (affect as interaction) (Boehner et al., 2005). It was interesting to see how the new technologies introduced in CHI 2021 were veering to the latter framing, where participants in Liu et al (2021 and Murali et al. (2021) were left free to interpret the emotions presented by the technologies and ascribe meaning themselves. It is exciting to see current affect-sensitive technologies taking this perspective as from a wider lens, it signals a shift from technologies being representational tools, to being participatory tools. I cannot wait to see what is in store next!
Rewards Placement can Determine Engagement in Apps
Our new research paper coauthored with Dr Diego Garaialde and Dr Ben Cowan from UCD, identifies the best location to place rewards when using gamification to motivate users. The research paper, which was published in the International Journal of Human-Computer Studies and is available online on Science Direct (sciencedirect.com), highlighted that placing rewards early on in the user interaction was more effective and encouraged users to use the app more.
Gamification has become a common technique for incentivising users to engage with an application however the placement of this tactic and how it impacts on a user is often not considered during the design process. We found that the value a user places on a reward diminishes the further into the future it is and placing rewards early in the interaction sequence leads to an improvement in the perceived value of that reward.
Speaking about the findings Diego Garaialde said: âRather than rewarding after longer interactions with the app, which is common in current gamified applications, designers should consider rewarding users early for deciding to interact with the app in the first place.â

Focusing during online lectures
In November 2020, we conducted focus groups with 38 incoming undergraduates. Here, we present the findings from this research – which may be helpful for lecturers seeking to support university students in remote learning.
Camera on or off?
Students missed seeing and being seen by peers and educators. Yet they found keeping a camera on during lectures intrusive. And seeing into the rooms of students who weren’t paying attention was demotivating.
Positive social media use during lectures
Social isolation led to social media use during lectures. Scrolling through feeds provided the stimulation needed to keep students at least partly engaged in the lectures they didn’t enjoy.
Online procrastination got out of hand
Pre-recorded lectures allowed a far more disruptive use of social media: bored students would pause the lecture and stream video content instead.
Technology doesn’t guarantee interaction
Students appreciated chat facilities and online breakout rooms. But when lecturers didn’t respond to questions in chat, or if starting a conversation in a breakout room felt awkward, students would lose motivation to engage in this mode of learning.
What can university lecturers do?
Use online quizzes and live polls! For the students we interviewed, interactivity was useful for helping to avoid distractions, and even more so for maintaining focus on lecture content. They wished that polls and quizzes were more often incorporated into online learning.
This research…
was supported by funding from the Medical Research Council (MR/T046864/1). It was conducted by Year 3 UCL Psychology students Selina He, Eloise May, Simran Suden, and Ella Verrells, supervised by Professor Anna Cox, Dr Anna Rudnicka, Elahi Hossain, and Professor Yvonne Rogers from UCL Interaction Centre.
