1. A method of determining virtual input at a data entry device having an input region, an input module and a processor, the method comprising: associating at least two input symbols or functions with the input region; defining a set of unique input objects with each unique input object having a defining feature that differentiates it from the other unique input objects in the set; assigning each of the input symbols or each of the functions to a one of the unique input objects; performing with the input module remote data acquisition of the input region of the data entry device to obtain data; processing the data with the processor to: a. determine which input region has been actuated; b. determine which one of the unique input objects actuated the input region; and c. determine the input symbol or the function associated with the unique input object; and outputting the symbol or performing the function on an output device.
