BubbleVerse - Augmented Reality in your bathtub

Augmented Reality is the technology that makes possible to overlay content on the real world. It can be provided for several type of devices: handheld (like mobile phones), headsets, desktop displays, and so on.

For handheld devices (more generally, for video-see-through devices) the 'reality' is captured from one or more cameras and then shown on the device display, adding some kind of content on top of it.

Imagine a 3D print design that marries the charm of tangible objects with the wonder of augmented reality (AR), creating an immersive experience that transforms the humble confines of a bathtub into an arena of digital enchantment. This design comprises a series of AR markers, embedded within floaters, designed to bob along the surface of bathwater, serving as conduits to a captivating augmented reality experience. This narrative unfolds further with the introduction of a dedicated website, engineered to breathe life into these markers, rendering a digital layer of interaction that is both engaging and mesmerizing.

A simple website was also developed using AR.js to render the animations over the markers using your browser, also in mobile phones!

You can use one of the following URLs:

Just open the website, allow webcam permissions, use your camera to point to the markers and… That's all! :)

Scenes

Currently the following scenes (collection of objects) are created:

Pirates!

Pattern1: Pirate Captain Pattern2: Pirate Ship Pattern3: Treasure Chest

The project is in an early stage, more scenes and improvements could arrive in future revisions. Only three markers available for now.

Safety

The elements were designed following this safety principles for children:

• Smooth Edges and Surfaces: Ensure that all parts of the toy have smooth edges and surfaces to prevent cuts and scratches. This can involve additional post-processing after printing, such as sanding down any rough areas.
• Non-toxic Materials: Use materials that are non-toxic and safe for children. PLA (Polylactic Acid) is a popular choice for 3D printing children's toys because it's biodegradable and made from renewable resources like corn starch. However, it's important to ensure that the specific PLA filament brand is certified safe for use in children's products.
• Choking Hazard Prevention: Design parts to be larger than the standard choking hazard size for children (typically parts that can fit into a small parts tester or a toilet paper roll are considered a choking hazard). This is especially important for children under the age of 3.
• Water Safety: For bathtub toys, ensure that they are designed to drain completely to prevent mold and mildew growth. Avoid designs that have small, enclosed spaces where water can get trapped.
• Strong and Durable Design: Toys should be designed to withstand rough play without breaking into small, sharp pieces. Consider the toy's structure and the infill settings during printing to ensure durability.

IMPORTANT: The marker base must be printed in WHITE and the pattern must be printed in BLACK color. It is necessary to increase the contrast during AR recognition. For the floater you can use any color you want except BLACK.

To increase buoyancy, “Lighting Infill” is recommended to increase air space inside the model

You will need to print multiple models:

• 3x marker_base
• 1x marker_pattern1
• 1x marker_pattern2
• 1x marker_pattern3
• 3x floater

1. Print the marker (White and Black parts)
2. Glue the black part onto the white base
3. Place the marker on the floater
4. Put your awesome marker in water
5. Have fun!

1. Print and assembly all parts
2. Place them in any surface, even in water!
3. Grab your mobile phone and browse this URL: https://t.ly/8XY1l
   Chrome is recommended
4. Point your camera to the markers.
5. Observe the models, rotate the base, move your phone…
   
   Don't forget to use some waterproof case for your mobile like this:
    

• v1.0:
  • Initial design and basic pirates related AR models

For the AR part of this project, several third party models are used in the website. Here the credits :)
