#CMT# #/CMT# The device is embedded in environment, and is based on usage of mobile and immobile symbolic control elements. Arbitrary objects are used as control elements and for data input and output. One or more predefined spatial positions are used as sensitive areas for data input and output. Change of characteristics of the control elements is used as trigger for the data input and output. The control elements are provided with one or more Radio-frequency identification (RFID)readers or RFID antennas and one or more Global positioning systemreceivers. #CMT#USE : #/CMT# Device for human-machine-communication. #CMT#ADVANTAGE : #/CMT# The arbitrary objects are used as control elements and for data input and output, and hence ensure a simple, efficient and economical human-machine-communication device. |
