Exploring Technology-Mediated Sharing Practices



Critical Review


Quantitative and Qualitative Inquiry 




Online social networks have made sharing photos and other digital content a common activity. Recently, a range of novel online services and connected devices have expanded the set of “things” to share – ranging from new types of digital content like music preferences and workout data to physical things like household items (“sharing economy”). The goal in this project was twofold: (1) to understand emergent peoples’ digital sharing practices beyond traditional social media platforms and instant messaging apps; and (2) to find commonalities and differences between digital and physical sharing in the context of sharing economy.

As the first stage, in collaboration with the Unit of Human-Centered Technology (IHTE) at Tampere University of Technology (Finland), I conducted a large-scale online survey study to understand needs, concerns and preferences of novel content sharing practices in the Web. I collected 200 responses about participants’ experiences with sharing six categories of “things”: music preferences; travel plans; sports activity; digital representation and contextual metadata about real-world items such as rooms and vehicles; virtual items in online games; and dietary preferences. For each category, I systematically described what our participants share and with whom, elicited corresponding privacy concerns, and outlined device usage practices to access novel sharing services.

At the second stage, I have inquired: “How does the sharing of physical artifacts differ from “traditional” sharing practices of photos and status updates?” This work consolidated the existing body of work in the Human-Computer Interaction scholarly area on both sharing personal digital content (e.g., social networking) and personal physical artifacts (e.g., apartment, car sharing), and identified both commonalities and differences between them. I summarized existing research on the diversity of shared content, users’ motivations to share, audience management, privacy & trust issues, and user experience requirements.
