In daily life, our hands are often occupied—whether holding a
child and a dog leash or riding a bicycle—making it difficult to
interact with devices. This challenge has led HCI research to explore
"hands-free" interactions like voice commands, though these are
limited in noisy environments and certain social settings. A recent
lab study using motion capture demonstrated the potential of toe
movements for interaction. Building on this, we investigate toe-
based interactions by embedding pressure sensors into a sock. Our
work tackles practical implementation challenges and explores the
feasibility of an interactive sock that captures toe movements. We
demonstrate that combining pressure and motion sensing expands
interaction possibilities, enabling a richer interaction vocabulary.
