ABSTRACT:
A portable, hand-held data collection terminal is of modular structure including, among other modules, multiple endcap modules and radio frequency communications pod modules, each of which may be chosen from a plurality of modules available for assembly into the terminal unit therby providing a plurality of modular combinations thereof. The functions of the multiple modular combinations are activated and controlled by a virtual trigger on a touch sensitive display. The virtual trigger may be positioned anywhere on the display to ergonomically accommodate different users. The terminal evaluates touch images retrieved from the touch sensitive display to determine whether they constitute an intentional touch. Unintentional touching will not activate the virtual button. Various other safety and power saving features are provided via orientation and motion sensors placed within the terminal.
