In everyday life we often fnd ourselves with both hands occupied,
e.g. while holding a child in one hand and a dog leash in the other
or riding a bicycle. These situations limit our ability to interact with
our devices, leading to HCI investigating "hands-free" interactions
such as voice commands. However, they are limited in noise envi-
ronments and certain social situations. A recent lab study using
a motion capture system has shown that toe movements might
be a useful way of interacting. In this work we advance this re-
search by exploring toe interactions through integrating pressure
sensors in a sock. We address practical issues of implementation
and applicability of an interactive sock capable of capturing toe
interactions. We show that combining pressure with movement
sensing can increase the interaction possibilities, allowing for a
broad interaction vocabulary.
