The document discusses kinetic user interfaces (KUI) where motion is used as an interface. It describes three projects - the Smart Badge Project, EPCFind, and RelateGateways Framework - that use motion to trigger contextual services, log entries, and discovery of co-located services respectively. The Smart Badge Project uses motion within buildings to trigger services for users, EPCFind uses motion to log the location of objects, and RelateGateways Framework uses motion to discover nearby pervasive services.
