 ==== Processor ====
+Using the KISS design principle, we decided early on to use a Computer on a Module for our main processor.  That way the hardware architecture would already be connected to the processor, leaving us more time to deal with other design decisions.  We ultimately choose a Gumstix Overo processor, that uses the ARM-A8 architecture, is compact (58 mm x 4.2 mm), lightweight (42 g), includes 512 MB NAND ROM and a Micro SD port to store software.
 ==== Input / Output Methods ====
-It was known right from the start that an LCD module would be used to display any sensor data.  But, what was not known was what input methods would be used for a user to interact with the User Interface of the Tricorder.  As the initial design shows, we considered using push buttons which would allow for tactile sensation when a user presses them.  When choosing the LCD module, we considered a non-touch screen version, a resistive touch screen version and a capacitive touch screen version.  The resistive touch version could only detect one touch gesture at a time, while a capacitive touch version could detect multiple.  Do to cost, we chose the resistive touch version, was able to get that working, so we decided to remove the push buttons, and just use touch gestures on the LCD module for user input.
