Buttercup – African Slave Doll

In this video, Dr. Gwen Graham of EKU shows of her family heirloom – a slave doll named Buttercup. She wanted to share this doll with her f2f and online students without bringing in the physical doll, and perhaps damaging it in the process. The doll will be available to students via this video and interactive 3D model interface.

To make this augmentation possible, original doll was scanned into a 3D model, converted to a .FBX file, and used in this video lecture via Augmeted Reality interface.

Slave Ship – The Birth of African American Art

This video explains the beginnings of the African American art with the use of Augmented Reality. This model (ship) is built using Google Sketchup, and used with Metaio AR software to augment and design the final scene. Dr. Graham used the marker to explain various parts of the travel African slaves had to endure while being transported  to America.

Google’s Project Tango and Augmented Reality

google_tango-1392983456493Google recently announced project Tango – a 3D mapping framework that will allow for simple scanning and virtual generation of a real world 3D environment. This project falls in the category of several sensing applications that utilize sensors such as Microsoft’s Kinect and PrimeSense’s 3D,  Pelican Imaging, Softkinetic, and PMD that has emerged in the recent years.

Project Tango includes SDK and a phone like sensing device that is similar to Kinect in functionality, although it appears to be missing a depth sensor and texture projector. These sensors allow the phone to make over a quarter million 3D measurements every second, updating its position and orientation in real-time, combining that data into a single 3D model of the space around the user.

This framework will be beneficial when creating augmented reality experiences, and I assume that there will be a close integration with Google Glass. I can see this being used in processes where a 3D point map of real space would be needed such as drone navigation in warehouses or augmented reality scenarios. Imagine creating a 3D point cloud of a factory floor, and incorporating various scenarios such as fire or falling piece of equipment that would play out when user physically approaches the trigger area. Such scenario would be great for training. Another example would be creating a scan of museum space, and loading various audio/visual material that would supplement existing exhibits. Such supplementary material would be visible with the aid of Google Glass or similar AR interface. Tango device could also be useful for 3D model generation, a topic we previously covered here, and here.

Tango offers a glimpse of things to come in near future. Google is doing a great thing here by developing a framework that will help the future generations of artists, scientists, hobbyists and other visionaries create new ways of interaction with our environment.

Augmented Reality Magic Book: Solar System v.3.0 (Mobile and Desktop)

solar_system_v3This is the third iteration of the augmented reality solar system project. We posted an early version of this project using BuildAR framework that worked only on desktop computers in 2011. Then we added a Flash implementation of the same concept with downloadable lesson and source plans in 2012.

As we previously mentioned, we recently switched to Metaio framework which enables us to publish our projects as mobile applications (via free Junaio AR browser – app for iOS and Android) and desktop applications (downloadable standalone packages). This latest version of the Solar system comes with a redesigned book titled Augmented Reality Magic Book: Solar System. This book contains essential factual knowledge about the planets of the Solar system (, 2013), and it comes with a set of interactive AR markers that project multimedia content such as 3D models, videos, images, and audio. Each planet of the solar system has 2 markers: main marker with a 3D model of the planet, and another marker that contains supplementary content. The book is available for download for free in .pdf and .pub formats. The content is taken from, and if you have Microsoft Publisher, you are free to alter the content under this Creative Commons license (Attribution-NonCommercial 4.0 International).

Our intent is to make this book available to the general public, specifically K-12 teachers, parents, and students, with a goal to make learning more fun, engaging and constructive. This aligns with our ongoing goal to further explore the use of Augmented Reality in learning and education, and to provide broader community with free meaningful, useful and engaging AR content and framework.

Download the Augmented Reality Magic Book: Solar System: Publisher (.Pub) | Adobe Acrobat (.PDF)

Download desktop application: Win | Mac.

For mobile applications, you will need to download Junaio browser app from Apple store or Android Marketplace to your mobile devices.

Generating 3D objects – Part 2

Model of Vespa being captured with 123d Catch

It’s been a year since we described how to create an accurate 3D models  by using ReconstructMe. A lot of things have changed in our little shop, and we reflected a bit on the work we created for the past 3 years. The use of Augmented Reality has expanded, and AR entered mainstream. Tonight I googled “Augmented reality in Education”, and I ended up reviewing over 30 search result pages of AR projects, articles and presentations on this subject. Amazing stuff.

We are planing to publish several new projects that are compatible with mobile devices and Google glass. We are now switching to Metaio SDK which will allow us to develop AR projects on mobile devices as well as on the PC platform. We will keep you updated.

Back to the topic of 3D scanning and 3D modeling. The latest app that comes pretty close to streamlining 3D model generation is Autodesk’s 123D Capture. If you are not familiar with this tool, 123D Capture will let you take multiple images (up to 40 on mobile app, up to 70 on PC) of an object you wish to turn into a 3D model,  and then convert them into a textured 3D model. Conversion is actually done on Autodesk’s servers, since the application uploads the images to Autodesk’s servers for processing. Depending on the server load, it takes around 5-10 minutes for model to be generated, and what comes back is a fairly accurate (80% complete) 3D model. If you perfect the process, you can create 3D models fairly rapidly. You can judge results by yourself:

We are really impressed with the final results, and will be using this tool in our upcoming projects. Meanwhile, check out this intro tutorial on 123D Catch:

Lunar Phases Astronomy AR Lesson

Augmented Reality Lunar Phases Lesson

Part of the Augmented Reality Lunar Phases Lesson

This lunar phases augmented reality lesson was developed as a part of my doctoral studies, and I used it as a primary  learning content used in the AR experimental group. I chose lunar phases for my research because (a) it is a concept that depicts material rich with spatial information; (b) it represents a concept that is often difficult to grasp; and (c) it was suggested as a suitable learning content for AR treatment by several studies.

The lunar phases lesson consists of 6 sections:

  1. General Introduction to the relationship between the earth and the moon,
  2. Introduction to the lunar phases,
  3. First quarter,
  4. Second quarter,
  5. Third quarter, and
  6. Fourth quarter.
Student Interacting with Augmented Reality Lunar Phases Lesson

Student Interacting with Augmented Reality Lunar Phases Lesson

Each section explains the relationship between the earth and the moon, and combined together, creates one coherent lesson about lunar phases. This lesson has been validated by 2 experts who hold PhD’s in astrophysics, and based on observations during the data collection (n=182), students enjoyed it very much. I must note that I was not able to measure the differences between the experimental group (AR) and control group (images and text treatment).

To use this material in your classroom (free), you will need to do the following:

  1. Download both “AR scene files” and “AR + text lunar phases” PDF document.
  2. Print out the “AR+text lunar phases” PDF, as this lesson will serve as your primary instructional material.
  3. Install free BuildAR viewer.  
  4. Plug in your Web cam into the computer. You will need a working webcam to run this AR lesson.
  5. Unzip the “AR scene files”.
  6. Open “Print these markers” folder, and print “All_Markers.doc”. Once printed, cut and separate the markers, and glue them to foam board pieces.
  7. Once all complete, click on “Scene_5.scn” to run the BuildAR software.

If you have any questions, please feel free to email me.

Here is an example of interaction between the student and lunar phases lesson:
