CHI Equity


In keeping with an ongoing effort toward greater inclusion and equity at CHI, we’re happy to announce the chairing of a new position: CHI Equity. Meant to help build greater capacity for inclusive practices and foster a culture of respect, this position is tasked with a number of responsibilities: from advocacy and service/facility establishment to communication between other SIGs and chairs; program development; training programs; space-making; accountability maintenance; and on-the-ground support for equity-related efforts at the conference.

CHI is an enormous event and institution. It reflects the work of many hands, minds and hearts, and many of the equity initiatives and programs would not exist without dedicated volunteer chairs. Beyond the extensive work of the General Chairs and Assistants to the General Chairs, CHI currently involves efforts from: Local Arrangements Chairs, Accessibility Chairs, CHI Family/Childcare Chairs, Diversity and Inclusion Lunch Chairs, Language Inclusion Chairs, Newcomers Chairs, Sustainability Chairs, Communications Chair, Telepresence and Livestreaming Chairs, and countless others and their surrounding support communities. With over 50 different chaired positions responsible for the many initiatives at CHI, the transmission of information (be it feedback, lessons, plans or needs) is complicated. Small mistakes are magnified, and sometimes large issues are overlooked. Part of our role is helping with communication, doing what we can to ensure better institutional memory and on-the-ground initiatives.

It’s our inaugural year, so our position is largely in development and administrative. However, we’ve done great deal of review: what’s been working for past participants, what hasn’t, and what’s possible within organizational limitations. We’ve consulted with over 60 professionals and organizations with long-standing experience in equity, capacity-building, and organizing. And with the support of the CHI steering committee and CHI 2019’s general chairs, we would like to announce several initiatives. Alongside our internal efforts to build upon previous years’ work, we’d like to highlight the following initiatives (and encourage you to visit the Equity page for more information on each):

  • ALLYSHIP PROGRAM: This year you will see allies (designated by an “ALLY” pin) throughout the entire conference. Selected for their past experiences in equity-related activities and organizing, these volunteers have received training by us in basic bystander intervention, harassment, and discrimination management, as well as relevant policies and CHI Equity procedures. They are friendly and informed faces we encourage you to approach whether you have questions about equity matters, need direction, or are looking to file a report. If you would like to volunteer as an official ally, please indicate so on your registration!
  • LISTENING POST: Another opportunity to hear and be heard, there will be a drop-in “listening post” event on May 8th from 8:00-10:20am, in Island B CROWN. This will be an opportunity to openly express your experiences, thoughts, wants, and concerns regarding your CHI experience, to the Equity Chairs and other organizers.
  • REPORTING SYSTEM: In the event that an attendee experiences or witnesses harassment or discrimination during their time at the CHI, we encourage you to file a report. Doing so helps keep us aware of recurring issues, problematic individuals, or structural inequalities that we may have overlooked.
  • CHANNELS FOR COMMUNICATION: In addition to revising the standard post-conference survey, we have added the listening post event, one-on-one’s with the Equity chairs during CHI (just flag us down if you see us in person!), a report-filing system, allies, and an anonymous message center.
  • MULTI-FAITH QUIET ROOM: This year, an on-site multi-faith room has been secured. Rules and guidelines, compiled from best practices across international sources, will be posted outside the room.
  • ALL-GENDER BATHROOMS: New this year, SIGCHI has adopted a policy for all-gender bathrooms (restrooms) that applies to the organization of all SIGCHI-sponsored conferences.
  • BABY-CHANGE FACILITIES: Please note that the 2019 conference venue features change tables for infants in separate rooms apart from the restrooms.  
  • DESENSITIZATION ROOM: Participants have shown continued support for an on-site quiet space to decompress, reset, or temporarily distance themselves from the high-intensity stimulation of the conference.
  • BETTER BADGE PRONOUNS: All attendees will be given the option to self-identify (or not) on their badges during registration. These badges will be checked and proofed prior to distribution.
  • IMPROVED DIETARY REQUIREMENTS: We’re working closely with the registration team and SEC in order to accommodate the wide range of dietary needs during the conference.

We are extremely motivated to start laying the groundwork for the sustained growth of equity-related efforts in our conference community. We’re here to be accountable to you, help communicate across the labor of many hands and hearts that make CHI possible, and to do what we can to facilitate better community norms and a culture of understanding at CHI. Follow us, find and speak with us during the conference, and head over to the equity page for a lot of important information, community guidelines and events!

With more on the horizon, we look forward to seeing you at CHI 2019,
Your equity chairs for 2019,
Cayley MacArthur & Cale Passmore

CHI 2019 Cowl Knitting Pattern

This year’s theme for CHI is ‘Weaving the Threads of CHI’, inviting us to see the connections between different strands of research and how they connect the field. To provide the community with an opportunity to reflect on how different aspects of the field come together to create something each of them could not do individually, we offer up a knitting pattern that visualises the ‘Threads of CHI’. These knitting patterns are provided by Katta Spiel, Assistant to the General Chairs.


Yarn: The sample piece uses fairalpaka DK yarn (100m/50g). A finished piece requires about 1 ball o the main colour (MC; teal) and about 20g of the contrasting colour (CC; tangerine).

Needles: We used 3.5mm double pointed needles (dpns) for the sample piece. You might prefer to knit with 40cm circular needles.


  • knit (k)
  • purl (p)
  • knit through back loop (ktbl)
  • twist through back loop (twbl) – insert right needle into second stitch on left needle and purl without dropping, then ktbl into first stitch on the left needle, dropping both together
A photograph showing a finished knitted CHI 2019 cowl.

Stripe Pattern

Repeat all parts for the round (chart below).

  1. p1,k1tbl,p1
  2. repeat step 1
  3. p1,tw1tbl
  4. p2,k1tbl
  5. move first stitch of the round to left needle, repeat step 3
  6. repeat step 4
  7. repeat steps 5 and 6 twice more
Instructions for the stripe pattern.

Mosaic Pattern

Each round seen on the chart is knitted twice, once as a knitted round, once as a purled round. Note that after each garter ridge, colour changes, starting with teal. Essentially, you start with a knit teal round according to the black stitches in the chart slipping all white ones (with teal yarn in back), then you purl the stitches you knit previously, slipping all you slipped previously. Then you switch to the tangerine and knit all white stitches in the chart (indicating row 3), slipping the black (a.k.a. teal) ones and repeating with a purl round. This sounds much more complicated than it really is. You can also find an introduction to garter stitch mosaic patterns here.


The pattern comes in two sizes: S/M and L (sample piece shown in S/M). Instructions are given for S/M (L). The pattern is knit in the round.

  1. with MC cast on 108 (126) stitches; connect in the round be careful not to twist.
  2. purl 1 round, knit 1 round, purl 1 round
  3. knit Stripe pattern 36 (42) times through the round
  4. knit 1 round, purl 1 round (twice)
  5. switch to CC
  6. knit 1 round, purl 1 round
  7. knit Mosaic pattern 6 (7) times through the round
  8. knit 1 round, purl 1 round, cut CC
  9. with MC: knit 1 round, purl 1 round (twice)
  10. knit Stripe pattern 36 (42) times through the round
  11. knit 1 round, purl 1 round, knit 1 round
  12. bind off loosely by purling the last round
  13. weave in ends and block lightly, if desired.

Making CHI More Accessible

Now that CHI is just around the corner, we would like to invite you again to communicate any accessibility needs/requests by the early registration deadline, which is Monday, March 18, 2019. These needs may include ASL translation and special equipments, food requirements, accessibility issues in terms of getting around the venue, etc.

We have been working on a few items, including:

  • Working with student volunteer (SV) chairs to train student volunteers to handle accessibility issues during the conference;
  • Ensuring that the washroom signage are following the SIGCHI guidelines;
  • Ensuring that paper programs are available to those who need or prefer them;
  • etc.

A few other things you should know:

  • CHI 2019 will be held in the three different venues across the central SEC, Crown Plaza Hotel, and Armadillo building. Therefore, you will have to walk a fair amount to travel across these venues;
  • We do provide a desensitization room, a quiet small low sensory input room, for those who need to disengage;
  • CHI is flash-free, which means that there will be no flash photography allowed at the conference, as it will affect people with epilepsy or those prone to migraines.

For other information about accessibility at CHI 2019, please consult:

  1. The CHI 2019 accessibility FAQ page;
  2. The conference venue (SEC) accessibility page.

From your accessibility co-chairs,
Edith Law (University of Waterloo)
Sunyoung Kim (Rutgers University)

Announcing our opening keynote

We are excited to announce our opening keynote speaker: Dr Aleks Krotoski.

Announcing our closing keynote

We are excited to announce our closing keynote speaker: Dr Ivan Poupyrev.

Talking about CHI and Sustainability

One of our goals for CHI2019 is to start making CHI more sustainable.

There are hard questions we all must face if we care about our planet, its ecosystem, and the impacts humanity is having (and vice versa) [1], [2], [3]. As academics, educators, human beings, what role do we play in our work and in our practice as a community of conference goers? In our SIG at CHI last year, we pledged to start this conversation at CHI. We’re grateful to the general chairs who have, for the first time, created a sustainability role for us to make a start on addressing these important questions.

There can be no doubt, making a conference sustainable is not easy: by far the most carbon intensive thing most of us will do is utilise air travel, yet this has become an essential part of modern careers and lifestyles. Tackling this will require thinking again about the very existential notions of conferences as we know them. This year, a virtual PC meeting, went some small way towards offsetting this as far fewer people travelled than would normally. The conference venue (SEC)’ ‘trees for life’ programme, which aims to offset some of the venue’s footprint by planting new forests, will also help. However, we should not fool ourselves into thinking CHI 2019 will be entirely sustainable!

We will however make as many adjustments that benefit environmental sustainability as we can – some of which will impact you as attendees! Concretely, we are:

Targeting a reduction of single use plastics and hard to recycle paper. A conference like CHI can create a large amount of plastic and hard to recycle paper waste such as our name badges, disposable cups, and promotional materials. For CHI 2019, we aim to reduce the amount of printed leaflets and promotions, including the ones that were handed out in previous years as part of the package attendees received at the registration desk, and minimize the amount of disposable cups at the venue. For this year, this means:

  • No bag by default. We have decided that there will be no conference bag by default for attendees on the grounds that these are often discarded in any case, and we have long since moved past printed proceedings. Instead we are exploring an option to buy a high quality long life bag if you need it. If you have one, why not bring a bag from a previous CHI? – the earlier the better!
  • Hydration stations. There will be water coolers where you can refill your own bottles, so please do bring one if you have one.
  • Reusable lanyards and badge holders. We will be moving to more generic lanyards that can be reused year on year.
  • Shared transport options. There are excellent public transport links to the venue, for instance, we’re close to Glasgow train station, and there are local bike hire schemes with cycle parking at the venue. We’ll be working to provide more information on this in coming weeks.

Beyond these changes, we are aiming to:

Benchmark the overall carbon footprint of the CHI conference. To help target reductions of the carbon footprint of CHI on an ongoing basis, we must first understand where the opportunities for reduction lie. For CHI 2019 we have been working closely with SEC to promote their green and low carbon initiatives (“the SEC team has implemented over 15 initiatives to aid the goal of achieving zero waste to landfill by 2020”) and their carbon offset programme supporting Scottish Forestry (Trees of Life), as well as gathering primary data on the energy used for our conference. Look out for our reports on our 2019 benchmarks in a future blog post.

Working with caterers to providing sustainable food. We are pushing for locally sourced, healthy and sustainable food choices during breaks and at catered events. By reducing the number of food miles (e.g. the mileage that the food has moved through supply chains), rethinking the amount of high carbon ingredients (e.g. red meat, imported fresh fruit and vegetables) in the menus, and asking for sustainable sourcing, we are aiming to reduce the impact of CHI’s food where feasible.

For the future, we will:

Identify challenges in the of planning CHI.
Some of the potential barriers that we have identified are:

  • Cost. Often, more sustainable choices are more expensive. To help drive a sustainability agenda for the CHI conference we need to frugally plan how to enable sustainability without passing additional costs onto attendees.
  • Reducing food waste. Due to issues around food safety it can be hard to donate “waste” food to local charities.
  • Varying International Policy and Sustainability Commitments. Given the varying cultural interpretation and commitments regarding sustainability, food and the environment we expect to face a different array of challenges as CHI moves from host to host.
  • Timelines for change – perhaps naively, we came into this process thinking we could change everything! As some of you may suspect, organising a conference as large as CHI takes around 2 years (and many of the decisions, such as the selection of venue takes place even further in advance). The Sustainability Chair role at CHI was created at the kick-off meeting in July 2018 (roughly 13 months into the process of organising CHI 2019). We now realise, that this ship will take longer to turn! A number of commitments have already been made which impose certain constraints regarding sustainability years before any single event. There are also very real budgetary constraints and associated practical trade-offs. We will be documenting this to help factor sustainability decisions earlier into the planning cycles.

For 2020 (and beyond) we look to:

  • Work closely with caterers, venues, and logistics plans to help build deeper sustainability roots for CHI
  • Elect one (or more) Sustainability Chair(s) who are local to the venue, and can provide local, community and cultural contexts for sustainability and green initiatives and challenges
  • Engaging with the PC process to assess the viability of more interactive remote participation at the CHI conference, as well as supporting our telepresence attendance options
  • Producing documentation, guidelines or whatever for next year’s Sustainability Chairs – ensuring that there are 2 chairs who overlap each year for knowledge and network transfer
  • Develop a communications plan for displays and promotional materials

Who are we anyway? We are just volunteers from your community, helping raise the profile of sustainability. Sustainability has been driving our work for the last 8 or so years, focusing on various aspects of everyday life including reducing domestic energy demand, sustainable design, promoting sustainable food choices, and sustainable last-mile logistics. We invite you to join us in helping make a difference to CHI and beyond!

We are, Adrian Friday (Professor of Computing and Sustainability at Lancaster University), Oliver Bates (Chair of the SIGCHI Community on HCI and Sustainability), Christian Remy (Assistant Professor, Aarhus University), and Mike Hazas (Reader, Lancaster University).

A personal letter to the CHI community

One of our general chairs has written a personal letter exhorting the CHI community to handle discussions and complaints in a more constructive way – to choose CHIndness:

“It is great that people in CHI are prepared to raise concerns and issues. As an always-learning-growing community, we need to hear these concerns to make CHI events better. But it is how those concerns and issues are being raised that I think we really need to stop and reflect on. What is happening now, especially via social media, is negative, hurtful, and unproductive and often drowns the attempts at providing constructive feedback or community efforts to make the conference better. My hope is that we can find different ways of raising issues, engaging in discussions and effecting change that are respectful, kinder, more compassionate, and more solution-focussed.”

The key messages are:

  • There is no ‘CHI’, there is you and me. We are CHI.
  • The CHI conference event (and SIGCHI in general) only happens because of an enormous amount of volunteer effort, done willingly and with great care by your colleagues.
  • We are a learning community always trying to improve and constructive feedback is an important part of this.
  • The tone of current feedback and discussions on social media can be perceived as negative, hurtful, and counter-productive, with real health and well-being impacts for people involved.
  • We can engage in in a much more productive and care-ful way, and grow a kinder community culture.
  • Some basic strategies proposed towards this:
    • STOP, THINK before posting it on social media.
      • What is your real intention?
      • Is social media the best avenue for this?
      • Do you have all information to make the judgement you are making?
      • What assumptions are you making?
      • Is there a way of framing the issue orienting to solutions or exploring positive alternatives?
    • Before focusing on a complaint, come up with three positive things (that are getting better or things that are working well or similar).
    • Take just as much time and effort, if not more, to say thank you, to show appreciation, being specific, being personal, being generous.
    • We can be the culture change needed to make that happen.

We encourage you to read the full letter and to share it with your colleagues. And for you to help by choosing CHIndness!


Attending CHI can often feel like being in the middle of New York’s Times Square: Interesting things everywhere and a mass of people catching up and having interesting conversations. For a first time attendee it can also seem that everybody knows everyone. However, at CHI 2018 40% of attendees were at their first CHI, faced with an environment of knowing few in a place where everyone seems to know everyone else.

This year were are organising Lunch@CHI, organised lunches that connect new attendees over topics. If you want to attend such a lunch it’s easy: just pick the days you are available, tell us about your research interests and any dietary requirements. You can do all of this on the conference registration form when you register, or you can add it to the conference registration once you have registered. We will then get in touch shortly before the conference with the day and group (of up to 8 others) you will be part of, where you are going and when and where to meet. Each group will also have one experienced CHI attendee who can help you understand how to get the best out of CHI. Each person pays for their own lunch at the restaurant.

We’re also looking for experienced CHI attendees to lead each group. So if you’ve been to CHI at least a couple of times to connect with the freshest minds in CHI, then please fill out this form.

We hope Lunch@CHI will be a great opportunity to weave new connections with other first time attendees over the great culinary delights of Glasgow, that will last through CHI 2019 and beyond.

Explorations of Remote Attendance at CHI

Carman Neustaedter and Anthony Tang
CHI 2019 Telepresence Co-Chairs

CHI has created the opportunity for people to remotely attend the ACM CHI conference via telepresence technologies since 2016. The goal has always been to increase access to the conference for remote participants who would otherwise be unable to attend due to mobility impairments, chronic health issues, temporary travel limitations, or cost issues. This year:

  • The primary way to remotely attend CHI is through the live streaming of talks;
  • In addition, to support social interactions, we have created a programme that pairs up local and remote attendees through a mobile video conferencing setup.

Remote attendance has been carefully explored at CHI and other conferences. It has been carefully thought through and studied over a number of conferences. Ubicomp 2014 in Seattle, USA had 7 people attend remotely using Beam telepresence robots [1]; CSCW 2016 in San Francisco, USA had 19 people attend remotely using Beams [2]; and CHI 2016 in San Jose, USA saw 33 people remotely attend via Beams [3]. Each of these experiences was studied and, ultimately, it was found that remote attendees highly valued being able to use a telepresence robot to remotely be there, move around, watch talks, and engage socially with others. Beams worked especially well for small-scale social interactions with others, like during breaks and in-between sessions. Of course, the experience wasn’t without its challenges. Interactions were not always easy and sometimes local attendees were less excited about the Beams (e.g., blocking one’s view during a talk, being disruptive). But, for the most part, local attendees saw value in helping conferences create a more accessible and inclusive environment for people. Given the overall success, remote attendance continued at CHI 2017 and CHI 2018. Live streaming of talks was added at CHI 2018 in Montreal, Canada and this helped get around challenges with remote attendees finding it hard to see speakers and slides during presentations.

Telepresence robots present pragmatic challenges and other solutions are also needed. Over the years we also have faced pragmatic challenges with using telepresence robots at conferences. Telepresence robots require high Internet bandwidth over WiFi in order to work well. Beams (or equivalent telepresence robots) aren’t available everywhere and so we have had to ship them to each conference’s location from California, USA. This was not always cheap and did not present a globally responsive solution to reducing carbon footprints. While remote attendees helped promote sustainability by not traveling, as ironic as it is, the Beams still had to travel. CHI 2019 proved to be especially challenging when it came to telepresence robots for a number of reasons. Shipping costs to get Beams to Glasgow was high; the conference venue has a variety of levels, some narrow corridors, and different buildings making it hard for telepresence robots to move about; and, WiFi at the conference venue is not available at the bandwidth levels needed by Beams. (But don’t worry – WiFi should be fine for regular attendees! You likely don’t need the > 20 MBps upload and download speeds that a telepresence robot needs.) For these reasons, we decided to explore alternative ideas for remote attendance at CHI 2019.

Over the years, we have brainstormed a large number of different ways to support remote attendance at conferences, ranging from dedicated video conferencing tables in break areas and hallways to situated video conferencing links at the front of presentation rooms to programs that might pair up local and remote attendees. And, that is where we ended up going for CHI 2019.

Firstly, most paper sessions will be live-streamed, free of charge to people taking advantage of this. Secondly, we want to provide access to social interaction with our buddy/human proxy pairing of local and remote attendees.

Research has shown that ‘Human proxies’ can create an enjoyable experience for pairs of people. The idea started back in 2014 when two of Neustaedter’s grad students saw an episode of the US TV show, Arrested Development, where a man on house arrest uses a ‘surrogate’ to be present at work for him. The surrogate wore a head-mounted camera and could do things on the behalf of his boss. While meant to be humorous in the TV show, the students thought it would be fun to try the idea for real in one of their grad courses when one of the students was traveling and couldn’t be in class in person. The experience raised interested technical and social questions, so Neustaedter’s group decided to formally study the use of human proxies in more detail in two university classes. In the classes, pairs of friends tried out the human proxy experience; one stayed at home and attended class through a video conferencing link ‘worn’ by the other friend. The work was published at CHI 2016 and received an Honourable Mention [4]. One of the main conclusions from the study was that students really valued the experience of remote class attendance when paired with a friend. Classroom human proxies were not generally seen as a way to ‘control another person’; instead, it was seen as a way to do pairwise learning with a friend. Students liked being able to interact with their friend while engaging in the class and its activities. Of course, this type of experience still raises many interesting socio-technical questions and, done without the right intentions, could lead to challenging problems around ethics, privacy, autonomy, and much more. That is to say, we are fully aware of the complexities and issues with the idea of human proxies.

Creating networking opportunities through remote CHI buddies and proxies. When the challenges around remote attendance at CHI 2019 emerged, we thought that human proxies may be a possible solution to explore. We envisioned it as a networking opportunity where those local to the conference location could volunteer to ‘bring in’ a remote attendee using a wearable video conferencing system – e.g., a tablet that could be hung around one’s neck, carried in one’s hands, or held at one’s side. The local volunteer could take the remote attendee around the conference venue so they could interact with people and experience the social aspects of CHI like talking with others, seeing demos, etc. To see paper presentations, the remote attendee could watch the live streams of talks on the web. The benefit to the local volunteer would be that they could get to know more people at CHI by attending ‘with’ the remote person, and vice versa. Thus, we saw it as a valuable opportunity for both the local and remote person. We thought being a local volunteer could be especially valuable for newcomers to CHI such as new grad students who may not know a lot of people and want to network with others. It could also be a great way for a lab group attending the conference to involve one of their colleagues who can’t be there. Anybody who is interested can contact us and ask to participate as a proxy. There’s no intention of coercing anybody into being a proxy and proxies can certainly choose what they do to help out the remote attendee.

Given the number of people who have attended CHI remotely over the past two years, we anticipate that there might be up to about 5 human proxy pairs at any one time. Thus, it was not seen as something that would be implemented on a massive scale. Remote attendees will have to pay a small fee to help cover the costs of enhanced WiFi as well as the technical setup. It’s not a means to pay a proxy.

Overall, we see the use of ‘CHI local buddies’ or ‘human proxies’ as a positive bonus for both local and remote attendees to enable social contact and interaction. Our initial CHI web page describing the telepresence experience was unfortunately too ‘functional’ and did not clearly articulate our intentions or what we see as the benefits. The recent discussions have also caused us to rethink some aspects of the implementation by drawing in more volunteers and exploring different mounting/carrying solutions.

We are hopeful that our updates and this blog do a much better job of describing the intended experience and look forward to the community’s support in enabling increased access via remote participation at CHI.
