Some Guidelines/Requirements For A Possible System (User Requirements/Use Case)

[Ira Laefsky]

I'd like to throw out some requirements, desires for the possible system we seek to build:

1. First that it accommodate both digital devices communicating over a serial protocol and up to a half dozen Analog Inputs so that we can gather data both from pre-made/appliance type sensors like Neurosky, Zeo, the SEEED Studio Pulse Ox, a Polar Heart-Rate Sensor, etc, and Analog Electrode and Op Amp Analog Sensors (such as GSR, a home built pulse sensor, EOG (eye movement via muscle potentials) and or Facial EMG measurements,

2. That it have some means of aggregating and routing data both from analog and digital sources to a cloud based Internet of Things Service via Cable Ethernet or Wireless connections.

3. That it provide some local data storage via USB either (or both of an SD CARD) and or a USB-Disk Drive (or SSD)

4. That it be safe (no ground loops), provide isolation, and possibly offer a battery powered option  It shouldn't seek to meed the ridiculously expensive and lengthy approval process of FDA devices--note that systems like BIOPAC Data Acquisition Systems are not approved as Medical Devices but must be safe enough to avoid product liability.

5. That some Control and Display Option exist to allow Oscilloscope like display of Waveforms, and Menu-Driven Input of System Menus.  This could be prototyped by the T35 LCD on the Gadgeteer and might eventually involve a Tablet-type Device or PC Display.

6. Both a fully Stand-Alone Data Acquisition and Router Device should be considered, as well as a DAQ-Data-Logger System attached to a PC like the Data Jack DAQ,
