Project 2 In-Class Activity

Setup (Pre-ACTIVITY):

If you completed a SideQuest activity earlier in the class, you can skip steps 1 and 4!

Download Sidequest Desktop App (create an account if necessary)
Download this apk file onto your computer
Plug your headset into your computer and open the SideQuest app.
If you havent completed a SideQuest activity before, from this page, start from "First Time Setup".
On the same page, follow the "Sideloading" Steps.

- - If step 3 of sideloading doesn't work, on SideQuest, navigate to the button on the top menu that looks like a box with a downward arrow on it (hovering over the button should say "Install APK file from folder on computer"). Click the button and select the APK file you downloaded.
  - If you've sideloaded from SideQuest before, you may need to delete any APK files you have already sideloaded -- this should not be happening ebcause the package name has been changed, but you can try this fix in any case.
  - Continue with steps 4 and 5. An application with the name "Earthquake SRP" should be listed under "Unknown Sources" (the last icon on the menu when you go to Library). The app should be ready to open on Quest. (You should see a map with pins in front of you somewhere when you open the application).

AR Visualization Activity (15-20 mins):

Part 1: Getting Started

Step 1:

Launch the "Earthquake SRP" app on your headset by navigating to "Apps", then selecting "Unknown Sources" on the left panel (the app should be listed there).
Upon launching the app, accept any pop-up alerts (i.e. "this app is asking for your spatial data").
Choose a roomscale boundary. You can choose a boundary from the main menu when you click the Meta button.

Step 2:

Re-center the visualization by pressing and holding the Meta button.
Begin exploring the earthquake visualization!
The map has an underside showing depth information for each earthquake, so don’t forget to look below.

The controls are outlined in the app, but are here for your reference:

Up / Down → Right Joystick (Up / Down)
Left / Right → Right Joystick (Left / Right)
Forward / Back → Side Triggers (Left / Right)

To interact with earthquakes using your controller:
- - Move your controller to touch an earthquake sphere.
  - Hold it there to feel haptic feedback (a vibration).

Once you feel like you've explored enough, you can move to part 2! Note the time on the stopwatch on the instructions menu before you move on, if you can.

Part 2: Full Interactive Mode

To switch to this part, press the menu button (☰)

This version includes expanded controls and customization options.

The controls for this version are the same as before, with some added functionality:

Change Map View → Press Ⓐ (toggle between light, dark, satellite views)
Adjust Pin Size (Fixed vs. Scaled) → Press Ⓑ
Toggle Depth Error Bars → Press Ⓧ
Toggle Text Labels → Press Ⓨ
Adjust Terrain Elevation → Left Joystick (Up / Down)
Show/Hide Tectonic Plate Overlay → Left Index Trigger

2D Data Activity (5 minutes):

Navigate to: https://earthquake.usgs.gov/earthquakes/search/
Under Date & Time, select "Custom". Change the year value of "Start (UTC)" to 2024 (i.e. the first 4 digits)
Under Advanced Options, set the Geographic Regions to the following:
- - North: 6
  - South: 0
  - West: 94
  - East: 103
Click Search

Explore the different earthquakes by clicking on them on the map or the sidebar (you don't need to click on any links, but can if you want to!). You can toggle different map settings by clicking on the layers icon at the top right of the screen.

FOR YOUR REFERENCE:

The haptic feedback for each earthquake sphere was created using corresponding seismographs for that particular earthquake!

What you feel in your controllers is essentially time-series virbation data. The vibrations were registered by a seismometer over 11 minutes for each earthquake (1 minute before it struck, 10 minutes after it struck), and are condensed to a roughly 11 second clip for this visualization.

To do this, I extracted the waveform from each seismograph and took a base earthquake sound (here). Using a custom script, I adjusted the amplitude of the base sound to match that of the extracted waveform -- corresponding to the the audio you hear and the vibrations you feel when your controller touches an earthquake sphere!

Some photos of the process are here for your reference
