In this chapter, I explore the ways in which families account for their use of domestic technologies. The family may be characterized in terms of dynamic properties emergent from the interaction between members. Family dynamics are expressed and managed through shared goals, family myths, rules and routines, conflicts and tensions, and its frameworks for explanation and understanding (Byng-Hall 1978; Reiss 1981; Olson et al. 1983). These properties affect the ways in which families variously construe the relationships between individual members of the family and between the family and the social world.
