Abstract:
1. A method of attaching data items to a physical environment, the method comprising: capturing surrounding contexts in a particular physical environment, the surrounding contexts including at least one of position context and object context, and capturing data items including at least one of visual data and audio data, wherein the surrounding contexts and the data items are sensed by a plurality of sensing means, wherein the position context represents a position in the particular physical environment and is based on a plurality of electric field intensities sensed by the sensing means, and where in the position context is based on a distance calculated from a similarity determination among pairs of an electronic field intensity of an electric wave and a unique ID of each apparatus transmitting the electric wave; attaching data items to the surrounding contexts; sending the attached data items and the captured surrounding contexts to an external apparatus for storing; transmitting the captured position context to the external apparatus for retrieving a data item stored in the external apparatus; and receiving the data item stored in the external apparatus based on the transmitted position context.
