This document discusses using signal frequency sweeps to enhance touch interactions between humans, liquids, and everyday objects. It notes that while signal sweeps have been used for decades in wireless communication, applying the technique to touch is novel. The technique works by sweeping different frequencies across the skin to detect touch, with potential applications in medicine, accessibility, and entertainment. While the idea may seem far-fetched, it demonstrates that enhancing touch interactions through technology is possible.
6. Signal frequency sweeps have been
used for decades in wireless
communication, but as far as we know,
nobody previously has attempted to
apply this technique to touch
interaction
