<div style='margin-left: 5%'>
<p>RPI StudySafe is an app that reveals the anonymous usage of Wi-Fi access points and aggregations of wireless users on
the campus network at <a href = ''; style = 'color: #990000; background-color: #f7f7f7'>Rensselaer Polytechnic Institute</a>,
Troy, New York. Analysis and visualizations are by students and staff of
<a href = ''; style = 'color: #990000; background-color: #f7f7f7'>The Rensselaer Institute for Data Exploration and Applications (IDEA)</a>.
This is an app associated with the COVID-19 contact tracing and campus network mapping projects.</p>
<p>RPI StudySafe is designed to present WAP data to on-campus users so they can make informed decisions on where to go for extended periods of time on campus.
The data can be interacted with in several ways, including selecting certain dates, times, locations, as well as through interactive geographical maps.
Geographic location and density of each WAP are combined by building, and the data is updated every two hours.</p>
<h4 style = 'text-align: left'>Find a Place to Study </h4>
<div style='margin-left: 1%'>
<p>The \"Find a Place to Study\" tab includes two visualizations: </p>
<span style = 'padding-bottom: 6.9px; font-size: 1.2em;line-height: 1.6em;font-weight: 400;color: #6e6e6e;'>
<li> A map of the RPI campus.</li>
<li> A barplot of WiFi access throughout the day.</li>
</ol> </span>
<span style = 'padding-bottom: 6.9px; font-size: 1.2em;line-height: 1.6em;font-weight: 400;color: #6e6e6e;'>
<p><h3 style = 'text-align: left'>How to Customize the Visualizations</h3></p>
Users can customize both visualizations in the \"Find a Place to Study\" pop-up menu with the following:</span>
<span style = 'padding-bottom: 6.9px; font-size: 1.2em;line-height: 1.6em;font-weight: 400;color: #6e6e6e;'>
<li>Building: To change the building, select the dropdown menu under <b> Choose a Building</b>.</li>
<li>Activity: If you would like to list the building options in the dropdown menu by activity rather than type, turn on the <b>List by Activity</b> button.</li>
<li>Day: To select a day within the past seven days, click on the tab of the day you would like to view.</li>
<li>Time: You will see that the current time is automatically the default time and is highlighted in pink on the barplot. To view a different time, simply click on any other bar, and the visualizations will automatically update.</li>
<span style = 'padding-bottom: 6.9px; font-size: 1.2em;line-height: 1.6em;font-weight: 400;color: #6e6e6e;'>
<p><h3 style = 'text-align: left'>Detailed Map Description</h3></p></span>
<span style = 'padding-bottom: 6.9px; font-size: 1.2em;line-height: 1.6em;font-weight: 400;color: #6e6e6e;'>
<li>The map displays a pin for each building on campus. </li>
<li>The color of the pin represents the individual building's percentage capacity at the time selected. The legend in the top left corner specifies the meaning of each color. </li>
<li>The user may click on any pin on the campus map to view more detailed information for that building with the barplot in the pop-up menu on the right. The selected building pin will be green once selected.</li>
<span style = 'padding-bottom: 6.9px; font-size: 1.2em;line-height: 1.6em;font-weight: 400;color: #6e6e6e;'>
<p><h3 style = 'text-align: left'>Detailed Barplot Description</h3></p></span>
<span style = 'padding-bottom: 6.9px; font-size: 1.2em;line-height: 1.6em;font-weight: 400;color: #6e6e6e;'>
<li>The barplot displays the WiFi access in terms of percentage of capacity for every hour throughout the day. </li>
<li>The current time is highlighted in pink, and the user may view any other time by simply clicking on a different bar.</li>
<li>Above the barplot, a short message will summarize the current situation of the building:
<li>If the building is less than 25% capacity, the message will read \"usually not busy\".</li>
<li>If the building is between 25% to 50% capacity, the message will read \"usually not too busy\".</li>
<li>If the building is between 50% to 75% capacity, the message will read \"usually a bit busy\".</li>
<li>If the building is above 75% capacity, the message will read \"usually as busy as it can get\".</li>
<li>The user may also move the \"Find a Place to Study\" pop-up menu around by dragging it to the desired position.</li>

<p>Some of the information displayed is approximated and/or may not be 100% accurate as it is an approximation of imperfect data.
Improvements to this application will continue to be made. </p>
