Designing with Biosignals: Challenges, Opportunities, and Future Directions for Integrating Physiological Signals in Human-Computer Interaction
ABSTRACT
Biosensing technologies are a rapidly increasing presence in our daily lives. These sensor-based technologies measure physiological processes including heart rate, breathing, skin conductance, brain activity and more. Researchers are exploring biosensing from perspectives including: engineering, human-computer interaction, medicine, mental health, consumer products, and interactive art. These technologies can enhance our interactions allowing connection to our bodies and others around us across diverse application areas. However, designing with biosignals in Human-Computer Interaction presents new challenges pertaining to User Experience, Input/Output, interpretation of signals, representation, and ethics. There is an urgent need to build a scholarly community that includes the diverse perspectives of researchers, designers, industry practitioners and policymakers. The goal of this workshop is to leverage the knowledge of this community aiming to map out the research landscape of emerging challenges and opportunities, and to build a research agenda for future directions.
ABOUT THE WORKSHOP
Bio-responsive technologies offer a plethora of fruitful opportunities for engaging user’s bodies in interaction. However, more research and discussion is needed pertaining to how we can and should design bio-responsive systems. There is a particular need to stimulate cross-disciplinary conversations to synthesize common vocabulary, definitions, and strategies to address challenges of within four topics: meaning-making, Input/Output (I/O) implementation, design of representations, and ethics. Below we list some possible questions we will consider.
TOPIC 1—Meaning-Making and UX of biodata
We will discuss the plurality of interpretations users can draw from perceiving biosignals, what effect this may have on individuals and society, and how specifics of the designs and context of use influence the meaning-making process. E.g., what does it mean if someone’s heart rate is 10 beats faster than their partner’s? How can we design biofeedback systems to avoid over-interpretation and support reflective meaning-making?
TOPIC 2—I/O of biosignals
How can we design for robustness, scalability and adaptability of continuously sensing biosensors themselves, especially when many sensors require calibration or are prone to noise from movement? What are the appropriate body feedback modalities to couple biosensing with?
TOPIC 3—Representing biosignals
We will discuss different dimmensions differentiating ways of representing biosignals: raw data vs. processed data imbued with interpretation, abstract vs. concrete, individual vs. aggregate, variant sensory modalities. What are the effects, challenges and opportunities associated with taking these approaches? How does this effect meaning-making, attention, privacy, sense of agency, etc.?
TOPIC 4—Ethics of sharing biosignals
What ethical questions arise when we engage user’s inherently private physiological data in interaction? What could be the unattended consequences of these technologies when we don’t fully understand the interpretive potential of biodata? How can user’s consent be implemented, as users themselves don’t have a complete awareness of and understanding of what their biodata may indicate? Who has access to these data? Through design and policy, how can we minimize immediate and future harm pertaining to privacy, agency over data, equity and power relationships, data use and storage?
Through discussion, we will aim to map out the key challenges and opportunities presented by biofeedback technology. The three rounds of discussion will build towards this outcome: (a) Round 1: hands-on provocations (exercises) + discussion; (b) Round 2: breadth roundtables based on topics (Meaning-Making and UX, I/O, Representing biosignals, and Ethics); (c) Round 3: depth roundtables based on application areas. Through rounds 1 and 2 we will identify common challenges, and in round 3 we will brainstorm how these challenges can be turned into research opportunities for future development of the field.
This is a hybrid workshop, thus all three rounds of discussion will happen in parallel at the venue and online with large group sharing of the outcomes at the end of each round.
CALL FOR PARTICIPATION
Biosensing technologies become increasingly more widely integrated in Human-computer Interaction. Biosignals provide novel opportunities of interaction, offering valuable insights into ordinarily hidden processes inside our bodies, revealing somatic information pertaining to our and others’ bodies, emotions, health, and cognitive processes. However, the integration of biosignals in HCI presents many challenges pertaining to UX, I/O, interpretation of biodata, representation of biosignals, and broader ethical concerns. To map out the landscape of existing challenges and future research directions, we invite participants working with biosignals to join a one-day hybrid workshop held at the one-day synchronous hybrid workshop held on July 11th at the ACM DIS2023 in Pittsburgh, Pennsylvania, USA 9am — 5pm. We welcome participants from HCI, design, digital art, psychology, education, health, philosophy, ethics and law. See the proposal and detailed workshop description for further information about the workshop.
We invite submissions presenting a project or articulating a challenge that relates to this call. Submission can be in the form of a:
- 2–4 page position paper in an ACM extended abstract format
- 2–5 min speculative design video with a 1-paragraph description
- previously published paper raising relevant questions about the workshop topics
Submissions should be uploaded here by June 1st AoE. Alternatively, if you are experiencing issues with the form, you can send your submission by email to biosignalshci.wks@gmail.com.
The organizing committee will select submissions illustrating authors’ perspective and expertise based on the quality and contribution of the work relating to biosignals integration. These submissions will be shared with all workshop attendees in advance to prime them for a stimulating discussion at the workshop. At least one author of each accepted submission must attend the workshop and register for both the workshop and the DIS’23 conference.
TIMELINE:
Submission Deadline: June 1st AoE (Anytime on Earth) June 30th AoE (Anytime on Earth)
Notification of Acceptance: July 5th
Workshop: July 11th 9am-5pm EDT (in-person and online)
