<h3 id="control">1.1. Ideas for Apps to Control the Camera</h3>
<div class="paragraph">
<p>There’s many types of applications you can build to control the camera. If you’re
just getting started with 360 images, I recommend you focus on building
an application to control the camera. You can extend the application to move
media from the camera to an external storage device for processing later or
to a third-party site such as YouTube, Facebook, or Google+.</p>
</div>
<div class="imageblock">
<div class="content">
<img src="img/guide/api_app.png" alt="Idea for application to control the camera">
</div>
</div>
<div class="paragraph">
<p>Here are some ideas from the community.</p>
</div>
<div class="ulist">
<ul>
<li>
<p><strong>Security</strong>: Take 360 images (not video) at set intervals. Transfer
images from camera to external storage device. The image is already in
equirectangular format. Apply your own algorithm to identify objects.</p>
<div class="ulist">
<ul>
<li>
<p>Key APIs: <a href="https://developers.theta360.com/en/docs/v2/api_reference/commands/camera.take_picture.html"><code>camera.takePicture</code></a>,

</li>
</ul>
</div>
</li>
<li>
<p><strong>Accident</strong>: Attach THETA to a camera platform
rigged to a commercial truck or a sign post near a dangerous crossing
such as a train crossing.
In the event of a traffic accident, a 360 degree image taken.</p>
</li>
<li>
<p><strong>Historical Site</strong>: Use a drone or autonomous vehicle to
take images of sites and apply tagging.</p>
</li>
<li>
<p><strong>Additional Functionality</strong></p>
<div class="ulist">
<ul>
<li>
<p>Add a timer delay to the camera</p>
</li>
<li>
<p>Create a remote control feature</p>
</li>
<li>
<p>Take four images at once using four cameras and four small devices like
a Raspberry Pi, each with a WiFi USB adapter. Trigger the images
simultaneously using the GPIO pins of the Pi.</p>

<h3 id="backend">1.2. Ideas for Back-end Server Media Management</h3>
<div class="paragraph">
<p>In this scenario, you build a web site that hosts 360 images or video.
You then build a mobile app that connects to THETA and takes the image
and uploads it to your special server. Example uses are real estate,
sporting event, music festival, travel.</p>

<p>A basic mockup of this concept built by a high school student
is available <a href="http://kaiyotesoft.github.io/realEstate/dynamic.html">here</a>.
The purpose is to show you how easy it is to start building
your own site with a JavaScript open source viewer and a basic
<a href="http://getbootstrap.com/">Bootstrap</a> template.
The site, including the source code for the
viewer software, is available as a
<a href="https://github.com/KaiyoteSoft/realEstate">GitHub repository</a>,
gh-pages branch.</p>
</div>
<div class="paragraph">
<p>The mockup of the controller is based on an existing Python/Pygame
application that was described in the
<a href="http://codetricity.github.io/theta-s/">Unofficial API Guide</a>. Full
source code available.</p>

<div class="paragraph">
<p>If your application has a mobile component, you should download the
<a href="https://developers.theta360.com/en/docs/sdk/">official RICOH SDK</a>
for Android or iOS applications.</p>
</div>
<div class="paragraph">
<p>You can extend this concept to make the images or video viewable
inside of a headset for an immersive experience. The easiest way to
get a demo with 360 video up and running is to use an existing
application such as YouTube to display the media.</p>
</div>
<div class="paragraph">
<p>If you want to embed a 360 image into your web application, you can look
at one of these existing applications:</p>
</div>
<div class="ulist">
<ul>
<li>
<p><a href="http://ggnome.com/pano2vr">Pano2VR</a>: Commerical. Pano2VR is an application to convert
spherical or cylindrical panoramic images into HTML5,
Flash, or QuickTime VR (QTVR) panoramas with features such as customizable
skins, tour building, multiresolution (gigapixel panorama), hotspots
and directional sound. There is a demo available. The image with the
demo will have a watermark.</p>

<p><a href="https://www.holobuilder.com/index.html">HoloBuilder</a>: Free.
HoloBuilder is a f
ree web platform that lets you create 360° and virtual reality content.
Build virtual tours from your 360° photospheres and enhance them with 3D objects.
