Automatic Triggering of Local Services Dominique Guinard 18.03.2008 Solution ,[object Object],[object Object],Problem Triggering services without the user requesting it can be disturbing same screen content as before the spatial criteria were fulfilled local services you printer display ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],2) By pressing the button, a map of the local environment and services are shown 1) When the conditions are fulfilled, a small button appears on the screen, which indicates that local services are available Idea I: Maps and Menus same screen content as before the spatial criteria were fulfilled printer display Gateways represent a co-located device. The user can interact with the device by clicking on the gateway or using drag-and-drop Idea II: Gateways
