1. A method of configuring an asset tracking device, comprising: displaying at least two user interface elements, each user interface element having an indicator movable in two different directions; receiving user input to move a first indicator of a first user interface element of the at least two user interface elements in a first direction or a second direction, moving the first indicator in the first direction representing increase of a first performance parameter of the asset tracking device and moving the first indicator in the second direction indicating decrease of the first performance parameter of the asset tracking device; receiving user input to move a second indicator of a second user interface element of the at least two user interface elements in a first direction or a second direction, moving the second indicator in the first direction representing increase of a second performance parameter of the asset tracking device and moving the second indicator in the second direction indicating decrease of the second performance parameter of the asset tracking device; generating and storing a mapper table by: (i) defining sets of configuration parameters of the asset tracking device wherein the sets of configuration parameters comprise at least two of (a) frequency of message transmittal by the asset tracking device, (b) processing speed of a processor in the asset tracking device, (c) light intensity of a display device of the asset tracking device, (d) strength of transmission signal, (e) enabling or disabling of functions of the asset tracking device, and (f) configuration of global positioning system receivers of the asset tracking device, (ii) computing a performance parameter value for each set of configuration parameters, (iii) selectively discarding one or more sets of configuration parameters that each map to a particular performance parameter value, and thereby prevent the discarded sets of configuration parameters from being stored in the mapper table, and (iv) storing remaining performance parameters and associated sets of configuration parameters on a computer readable storage device; determining, using the mapper table, configuration parameters corresponding to the performance parameters set by moving the indicators, wherein there are more configuration parameters than interface elements; configuring the asset tracking device according to the determined configuration parameters.
