This chapter concerns the use of manual gestures in human–computer interaction (HCI) and user experience research (UX research). Our goal is to empower gesture researchers to conduct meaningful research in these fields. We therefore give special focus to the similarities and differences between HCI research, UX research, and gesture studies when it comes to theoretical framework, relevant research questions, empirical methods, and use cases, i.e. the contexts in which gesture control can be used. As part of this, we touch on the role of various gesture-detecting technologies in conducting this kind of research. The chapter ends with our suggestions for the opportunities gesture researchers have to extend this body of knowledge and add value to the implementation and instantiation of systems with gesture control.

Chapter 11 returns to the beginning by revising the arguments on negativity made by Adorno and Agamben, as well as George Spencer Brown’s language of distinctions and of the nothing to help formulate this sense of renewed strategic need for both in-forming and un-informing. It is not much that we offer by way of a way out, but that is the point; it must remain in an uneasy and slightly impoverished space if it is to survive, it is strategy from the shadow.
