Abstract: | The RELATE interaction model is designed to support spontaneous interaction of mobile users with devices and services in their
environment. The model is based on spatial references that capture the spatial relationship of a user’s device with other co-located devices. Spatial references are obtained by
relative position sensing and integrated in the mobile user interface to spatially visualize the arrangement of discovered
devices, and to provide direct access for interaction across devices. In this paper we discuss two prototype systems demonstrating
the utility of the model in collaborative and mobile settings, and present a study on usability of spatial list and map representations
for device selection. |
