Social Interaction Design is not web design. It's not interaction design. It's about designing complex ecosystems that support conversation, collaboration, intimacy -- in short, community. Problem is, many people - even in the IxD world - don't understand what conversation is, or how to create engaging communities.
Many healthcare providers and startups are rushing to deliver on the promise of creating supportive online communities for people while simultaneously trumpeting personal health records and electronic health records at the same time creating potential privacy and trust issues.
To design Communities of Care, you must commit to writing a narrative of human behavior mediated through time and space. While great strides have been made over the last 40 years drawing on a rich history of Cybernetics and Human-Computer Interaction, those models of interaction are limited in explaining social and psychological modalities of social interaction in physical space and particularly in mediated online spaces which is becoming more the norm for collective and collaborative group social interactions in the healthcare industry.
