Case Studies

ISS is a premier venue for presenting research in the design and use of new and emerging surface and space technologies. Case Studies are the continuation from the ISS application papers in previous years. Case Studies are open to researchers and practitioners (e.g. in industry, in education, etc.) and share compelling stories about HCI practice based on real-world experiences that will be instructive and of interest to other members of the community. Based on the concrete cases of research and design, HCI practitioners and researchers will learn how HCI principles and methods can be applied in practical HCI work. For example, industry members can submit papers to share customer outcomes and iterative improvements over next-best alternatives, or educators might submit papers to share applications of HCI to iterate over prior instructional methods or to share novel approaches to teaching HCI topics. Reviewers will emphasize the connection between the real-world domain and the technology used. This connection may for instance concern a challenging domain, features of a system crucial for the real-world use context, a special design process, practical issues in implementation or deployment, or new business opportunities.


Case Studies should describe how a problem was addressed by HCI work carried out. They should describe the challenges experienced and how they were tackled, reflect on the experience, what could have been improved, and describe why the case study is of importance to the HCI community. Case Studies can also inspire HCI researchers to further investigate issues that arise from practical research and design work. Case Studies can illustrate, explore, report, analyze, summarize, challenge, or simply describe practical HCI work carried out to address a problem.


Case Studies should focus on topics relevant to the ISS community and can include but are not limited to the following areas:

  • Architectural concepts and emerging trends
  • Immersive analytics and data physicalization
  • Museum and art installation trends
  • Interaction paradigms around large surfaces (tangibles, pen+touch, etc.)
  • New and emerging body and space sensing technologies
  • Overview of social protocols, presence, territoriality, and proxemics
  • Evaluation methods for surface applications
  • Multi-touch interaction with mobile devices
  • Large scale and outdoor interactive spaces (projected interfaces, drones, ...)
  • Feel, smell, taste, temperature and splash user interfaces on surfaces
  • Affective spaces and surfaces
  • Novel and effective teaching of topics like the above
  • HCI teaching and education
  • ... and other exciting topics!

Case Studies differ from archival research papers in that Case Studies do not need to define themselves as part of the potentially longer-term body of academic research. Case Studies are not considered academic archival publications, but can be republished as such, as appropriate. They might not have as extensive a literature review as archival research papers, or might not explicitly add to HCI theory within an academic school of thought.


Preparing and Submitting your Case Study

A Case Study must be submitted via the PCS Submission System. The Case Study submission must have an extended abstract, and can also have supplementary material. We strongly encourage including a video as supplementary material.

  1. Extended Abstract (the paper). The primary submission material consists of an extended abstract in the ACM Master Article Submission Templates (single column; 4-10 pages). Note that we eliminate the old CHI extended abstract format (landscape) and use the same format as full papers. The extended abstract should describe the authors’ experience, focusing on the lessons you want readers to take away from the presentation. Your extended abstract must stand alone; readers must be able to understand the Case Study with only this material.
  2. Supplementary material. You may augment the extended abstract with additional material. Typical supporting materials include videos, documents (e.g., pictures beyond those included in the extended abstract) or interactive media (e.g., interactive prototypes). Authors who submit supplementary materials should also include a list of the supplementary items in their submission. This should explain the nature and purpose of each item submitted. (The list is not part of the extended abstract.)

Authors are strongly encouraged to work on improving the accessibility of their submissions, using recommendations found in the Guide to an Accessible Submission.


Case Study Selection Process

The evaluation of submissions will not be constrained by traditional academic expectations, but will be based on the significance of the Case Study’s contribution to the field of HCI practice and on how compellingly the story of the Case Study is told. Accepted submissions will be chosen on the merit and contribution of the report, not only on the quality of the outcome that it describes. This means that a valuable lesson learned from a poor outcome is just as acceptable as a valuable lesson learned from a good result.


Submissions will be reviewed by an expert panel of HCI practitioners and practitioner researchers. Authors will receive the reviews of their submissions after the decisions are announced, and should keep in mind that the Case Studies program is a Juried contribution and thus does not follow the strict peer-review process as applied to Papers. In particular, the Case Study review process does not allow authors the opportunity to submit rebuttals.


Specifically, the review criteria will be the extent to which the case study report accomplishes the following:

  • tells a convincing story of a real-world experience of HCI practice that will be instructive and of interest to other members of the HCI community
  • reflects on the experience, and describes why the case study is of importance
  • advances the state of the practice
  • clearly outlines any limitations of the report as well as of the activity described.

The extended abstract should contain no sensitive, private, or proprietary information that cannot be disclosed at publication time. Submissions may NOT be anonymous. However, confidentiality of submissions will be maintained during the review process. All rejected submissions will be kept confidential. All submitted materials for accepted submissions will be kept confidential until the start of the conference, with the exception of title and author information which will be published on the website prior to the conference.

On Acceptance of your Case Study

Upon acceptance, ACM will send you a copyright form, which you have to complete. Once completed, we will provide you with the new copyright information to be put on your paper. You can then submit the final version (including the new copyright notice) through the Precision Conference System by 15th October, 2021.

For each accepted case study, at least one author must register for the ISS 2021 conference. The authors are expected to present the accepted case study at the conference during their assigned paper session. Authors will also be required to upload a still image as well as a one-minute preview video that will both be used to advertise the demonstration before and during the conference.

More details will be provided in the following weeks regarding the organization during the conference and the adaptation that will be implemented due to the virtual format of this year’s ISS conference.
