In the DNS / Stratus usability trials, neither machine nor user is settled / experienced / established. Consequently, the interactions are part of the process of establishing the identity of the interacting entities. In other words, in this situation, the interaction between machine and user invites assessment both of whether or not the machine is acting like a real machine and whether or not the user is acting like a real user (82)
[…] user configuration involves boundary work. The user’s character and capacity, her possible future actions, are structured and defined in relation to the machine […] when there is still considerable ambiguity both about the capacity [capability?] of the machine and about the character of the user, the machine becomes its relationship to the user, and vice versa (89)
