touch screen display a radio frequency identifier rfid reader or receiver 41 and memory 43 may also be coupled to the computer referring to fig3 a configuration sequence 47 may be followed by model generation 45 and then an execution sequence 44 in the configuration sequence 47 a new sensor is configured and in the execution sequence 44 the sensor is actually used to collect information about activities being done by the user the configuration sequence 47 is repeated for each added sensor thus in the initial configuration sequence 47 for each sensor the user causes the selected physical sensor to interact with the system as indicated in block 46 the system then detects the sensor 32 at 52 this may be done by reading an rfid tag on the sensor using the rfid reader 41 so that the sensor 32 is identified other identification methods may include but are not limited by using infrared wireless communication pushing buttons on the sensor 32 and the user interface 40 simultaneously pushing a button on the user interface 40 while shaking the sensor 32 having a bar code reader on the user interface 40 to read a 1d or 2d code on the sensor 32 or using keyboard entry via computer 34 or user interface 40 of a sensor identifier number for example the sensor may have a bar code that identifies the type of sensor e g motion touch proximity etc and its identifier then an object selection system may be implemented in block 54 the user may select or identify what object the sensor is attached to in block 48 using a user interface 40 that may be the interface shown in fig4.
