Experiments from the practice based research suggest that a tool does not operate independently from the body that uses it. The lettering guide constrains the movement of the hand, the visit-card maker coordinates the actions of two participants, and An Instrument of Attention translates selected qualities of an encounter into another material form. In each case, what becomes possible emerges through a relationship rather than from either body or technology alone. What do these relationships do to bodily experience?

A tool does not always remain something outside me.

When I first use the lettering guide, the division seems obvious. My hand is here; the guide is there. I move the pen until I meet its edge. The edge stops me. I adjust my movement and continue. After using it for some time, however, this division becomes less clear. I no longer need to continuously think about where the edge is. My hand begins to anticipate it. I move with the constraint rather than simply encountering it as an obstacle. Something that began as a restriction outside my body becomes part of how my body moves.
