m.c. schraefel holds the post Professor of computer science and human performance- at the University of Southampton, and leads the Wellthlab where the mission is to explore if how and where interactive technology can help #makeNormalBetter for all.

In support of this mission, m.c. has developed the “inbodied interaction” approach– to help designers and engineers who are developing health tech align their designs with the complexity of the body, to work with the body. We challenge ourselves with questions like, how redress a cultural status quo that supports being over-caloried yet under-nourished, over stressed and under slept, and where our social communication technology seems to privilege over-talking and echoing rather than listening?

In this conversation, questions m.c. invites web scientists and hypertext researchers to explore:

  • What is the role of web science generally, and hypertext in particular in helping to create the infrastructure of radical cultural shift towards health?
  • How do we help people build resilience of knowledge skills and practices of health on the one hand, and support the infrastructure of health and healthful practices on the other, so health is as accessible as clean water?
  • how do we help people connect practice with experience of that practice so we can connect how we feel, with the pragmatics of how to feel better; and connect the pragmatics with the systems/infrastructures to enable access to those resources of wellbeing?
