This New Member Handbook summarizes and orients towards key activities and offerings of SIGCHI for those new to the organization. Please note that this Handbook leaves out many programs and activities in order to keep the introduction brief. For further information, you can go to the webpage and/or reach us out at


We present here briefly SIGCHI and its vision, values, and structures.  

What is SIGCHI

The ACM Special Interest Group on Computer-Human Interaction (SIGCHI) is the world’s largest association of professionals who contribute towards the research and practice of human-computer interaction (HCI). SIGCHI is a highly interdisciplinary society of computer scientists, software engineers, psychologists, interaction designers, graphic designers, sociologists, multimedia designers, information scientists, and anthropologists, just to name a few. What brings us together is a shared commitment to the examination, design, creation, use, and evaluation of technologies as they transform lives of those around the world. 

SIGCHI sponsors or co-sponsors 26 HCI conferences (and counting), in addition to hosting an even larger number of in-cooperation conferences. There are roughly 60-70 active SIGCHI chapters located across continents, which aim to promote local support networks for HCI students and professionals. 

SIGCHI is a volunteer-based organization and depends on the efforts of thousands of volunteers that keep it going. These volunteers make up SIGCHI conference organizing, program, and steering committees, chapters leadership, and various SIGCHI committees. These are all ultimately overseen by the SIGCHI Executive Committee

Vision and Values 

SIGCHI’s vision is focused on supporting conferences, engaging community, nurturing local and global presence, and building a learning organization. Take a look at our “SIGCHI Turns 40” Community Square article.

SIGCHI’s values include the following:

  • Pluralism: Being accepting of difference in cultures, languages, research methodologies, disciplinary homes, and more.

  • Equity: Towards removing barriers to participation and contribution across different kinds of difference.

  • Infrastructuring: Setting up robust and sustainable infrastructures, including those of committees, community support initiatives, and more.

  • Education: Of leadership and community through regular channels of engagement and communication.

  • Responsibility: Nurturing the ability to respond to changes around us, with leadership

  • Partnership: Building bridges and strengthening ties with those who share adjacent/aligned interests.

  • Community: With a commitment to engaging community throughout, in all undertakings, inviting continual feedback and support from all.


The elected president and executive vice-president work together to lead the SIGCHI Executive Committee (EC) and to ensure that SIGCHI members and volunteers are supported in attending, contributing to, and organizing current and future events and initiatives. They do this with the help of other EC members and a number of committees. 

Elected EC roles include, in addition to the president and executive vice-president, the vice-presidents for finance, communications, membership, and accessibility. There are also two elected vice-presidents at large who currently focus on SIGCHI's global presence and mentoring, respectively. There are additionally four appointed vice-presidents who oversee conferences, publications, operations, and chapters. There is also a past president, whose role helps preserve continuity across ECs.

Adjunct chairs are appointed when additional roles are needed on the EC. The current EC has adjunct chairs for awards, equity, partnerships, sustainability, volunteer support, community support, hybrid, and the web. Interactions Editors-in-Chief are ex officio members of the EC.

As the SIGCHI bylaws dictate, an EC term lasts three years. Each term begins with the election of 8 members of the SIGCHI community into key roles. The remaining 5+ members are appointed. 

You can reach out to the EC at


The EC oversees several committees. Some of these are led by an EC member, others are ad hoc committees led externally with liaisons within the EC. See the SIGCHI website for a complete list

Volunteers for all committees are recruited via open calls, following consolidated EC guidance. Ad hoc committees choose their own processes for recruitment, though the EC recommends open calls. Calls for EC members and committee chairs are conducted by the president, while additional committee members are recruited by the various EC members chairing the committees. Those interested in volunteering are invited to fill out the Open Call for Volunteers on SIGCHI’s Submittable page.  


Read below about membership, and its benefits and fees. 


Anyone who attends or has attended any of our conferences or chapter events is welcome to consider themselves a SIGCHI member. You can also become a paid member, which has costs and benefits as listed on our Membership page. SIGCHI includes students and professionals from a wide range of backgrounds, including but not limited to academia and industry. SIGCHI is increasingly establishing its global presence. As a large volunteer-run organization, it offers many volunteering opportunities. You can volunteer to help organize/lead a conference, run a chapter, or provide service on the SIGCHI Executive Committee or one of its committees or working groups. To volunteer at the conference or chapter level, you can reach out to the conference/chapter leaders directly. 

SIGCHI membership is obtained on the ACM website, but is NOT the same as ACM membership. You can be a SIGCHI member and not be an ACM member, and vice versa. It costs less to be a SIGCHI member and offers a different set of benefits. Sign up for SIGCHI membership

We describe here a few programs that are widely engaged by our members. 

SIGCHI Development Fund

The SIGCHI Development Fund (SDF) provides financial support for SIGCHI members to organize events and initiatives that spur communication, innovation, and expansion of HCI at the global and local levels. We especially solicit proposals for events and initiatives that promote SIGCHI priorities around equity, sustainability, accessibility, global inclusivity, hybridity, and safety.

Proposals are reviewed by the SDF Committee on an ongoing basis. Applicants can expect to hear back approximately one month after submission. For transparency, awarded proposals will be announced periodically on the SIGCHI Development Fund Recipients page. Please see the call for proposals on Submittable for details regarding submission, evaluation, timelines, and more. 

See our Frequently Asked Questions. You can also reach out at

Gary Marsden Travel Awards

The Gary Marsden Travel Awards (GMTA) provides travel support for attending SIGCHI conferences. Applications from students, early careers, and those experiencing financial hardship or lacking institutional support will be prioritized during review.

Proposals are reviewed by the GMTA Committee every two months. Applications must be submitted to a deadline that occurs at least a month before the conference. An accepted work is not a prerequisite for applying to the GMTA program, and early applications are preferred. Applicants can expect to hear back approximately one month after submission. For transparency, award recipients will be announced periodically on the SIGCHI website. Please see the call for applications on Submittable for details regarding deadlines, evaluation, timelines, and more.

SIGCHI CARES is a resource for those who experience discrimination and/or harassment in violation of ACM’s policies governing SIG activities and publications: policy against discrimination and harassment, policy on plagiarism, misrepresentation, and falsification; policy on coercion and abuse in the ACM publications process; and policy on roles and responsibilities in ACM publishing. CARES supports such individuals by helping them to work with long-standing members of the SIGCHI community, approachable and willing to listen and help navigate the SIGCHI and ACM reporting and accountability process. 

CARES offers an open and confidential conversation, with the dual intent of (a) creating better awareness of discriminatory dynamics on the part of conference organizers; and (b) increasing accountability of conference organizers, event staff, and conference attendees. CARES’ goal is to empower all SIGCHI community members to raise their voice if they observe such behavior. Note that in certain cases of imminent danger, including threats of violence, suicide, harm to children, etc., CARES committee members are required to report to appropriate authorities.

SIGCHI is a volunteer-based organization and members of the SIGCHI community are invited and welcomed—at all stages of their careers—to contribute their service to committees, conferences, and chapters. Activities range from being a student volunteer at a conference, being reviewer for conferences and journals, volunteering for committees–including becoming part of the executive committee for SIGCHI, and more. 

In a SIGCHI Committee 

All committees that report to the EC recruit via open call for volunteering on Submittable. Those interested in volunteering can go to this site and see which “active” openings are of interest to them. More targeted open calls are advertised first on the SIGCHI-Members list when they are ready, following open call guidance. 

In a SIGCHI Conference 

There are numerous volunteering opportunities available across SIGCHI conferences. These opportunities are managed by the conferences, and typically advertised on individual conference websites, and published widely on their social media channels. You can also directly reach out to conference leaders to identify volunteering opportunities. To register as a reviewer for SIGCHI conferences, volunteer on PCS, the system used by most SIGCHI conferences’ program committees.

At a SIGCHI Chapter

SIGCHI has a growing number of chapters worldwide, and many seek volunteers to assist with chapter operations, special services, speaking at technical meetings, and more. Check out Local SIGCHI Chapters for more information.
