Beyond the Screen: Defining the Materiality of Social Interaction Design (SxD)
Explorations in social interaction design
The paper outlines a collaborative workshop framework to define <b>Social Interaction Design (SxD)</b>, a multidisciplinary field merging social computing with tangible, embedded interaction. It establishes a research agenda for integrating socially generated data into the material fabric of everyday life beyond flat digital interfaces.
TL;DR
This paper serves as a foundational manifesto for Social Interaction Design (SxD). It argues that our social digital lives should not be confined to glass screens. Instead, by merging the data-rich landscape of social networks with the "felt" experience of tangible computing, we can create a future where social connectivity is woven into the very fabric of our physical environments.
The "Flat Layer" Problem: Why Digital Socializing Feels Disconnected
For years, HCI has moved in two parallel but separate tracks:
- CSCW & Social Computing: Focused on how we talk, share, and collaborate online (the "what").
- Tangible & Embedded Interaction: Focused on how we touch and manipulate physical objects (the "how").
The problem? Most "social" data is currently experienced as a flat, 2D layer of notifications and feeds that interrupts—rather than enhances—our physical reality. The authors argue that we lack a vocabulary to design social interactions that are "sensorily rich" and "materially present."
The Core Vision: Social Data as Design Material
The central insight of SxD is treating socially generated data not just as information, but as a material for design. The workshop explores three critical pillars:
1. Technologies of Presence
How can we sense the "quality of movement" in a public square or use "skin-based inputs" to mediate intimacy? The goal is to move from abstract data to embodied sociability.
2. Social and Cultural Reconfiguration
Technology doesn't just sit in a vacuum; it reprocesses how communities maintain connections. The method proposes an ethnographic look at how digital practices reflect (or distort) material social rituals.
3. The Design Space of SxD
The authors challenge designers to move beyond the relationship of "user and device" toward "community and environment," using the material properties of objects to convey the feeling of being connected.

Methodology: Research-through-Design (RtD)
To bridge these domains, the authors utilized a Research-through-Design approach. Instead of just talking, participants:
- Constructed a physical "Wall" (mimicking a Facebook News Feed) using adhesive cards to visualize ideas.
- Developed low-fi prototypes to explore "design futures."
- Used Pecha Kucha sessions to rapidly cross-pollinate ideas between ethnographers and computer scientists.

Final Analysis: Why This Matters Today
While this paper was published in 2013, its relevance has only grown with the rise of Ambient Intelligence and the Internet of Things (IoT).
The Takeaway: We must stop designing "social apps" and start designing "social environments." The true frontier of HCI isn't a better algorithm for a news feed; it’s finding a way to make digital connection feel as meaningful and tactile as a handshake.
Limitations & Outlook
The primary challenge remains scalability and privacy. While tangible social objects are beautiful in a lab or a gallery (as explored in this workshop), deploying them into the chaotic, privacy-sensitive world of public infrastructure requires a robust ethical framework that wasn't the primary focus here. Future work must address how "socially sensitive interactions" can respect the "right to be let alone."
