Tracer Eyes User Guide

This user guide is for the Tracer Eyes project.  Tracer Eyes is a component of the distributed project code named 'Tracer'.  The overall purpose of project Tracer is keep track of ingress and egress of patrons and staff from the library to facilitate the generation of usage reports and if necessary contact tracing lists of everyone ho could have come in contact with individuals infected with the novel corona virus disease 19 (COVID-19).

Tracer Eyes is intended to help staff tasked with greeting/managing the flow of patrons.  Its primary role is to provide a quick and seamless system for such staff to log ingress/egress records for all patrons and other staff.  The following sections of this guide will be concerned with the Workstation (powering on, logging in, rebooting, etc.), the Application (how to start the Eyes app, basic functionality, how to restart if there are issues), and Failures (which provides further details about handling errors and information about contacting Guy Gastineau).
