Inspiration

We wanted a way to visualize 2 dimensional diagrams interactively, but how did this thought come about?

  • In specific school lessons, it was hard for us to visualize diagrams like prisms in math and molecular structures in chemistry
  • We wanted an easier way to rotate and interact with 3-dimensional object

What it does

  • It allows users to see normally 2 dimensional objects in 3 dimensions.
  • Users are able to draw object with their hands
  • The user's drawing can be predicted by the press of the button and using a machine leaning algorithm referred to as Perceptron, the computer predicts the object and places a more realistic version of the object
  • The object is displayed in 3-dimensions by using an optical illusion that creates a virtual hologram

How we built it

  • Plastic sheets for the hologram
  • Leapmotion
  • Unity

Challenges we ran into

  • The angle of the plastic sheets was incorrect so we had to cut it out a few times and rework out the ratios
  • Apparently a Unity dll was corrupted but it took six hours to figure out

Accomplishments that we're proud of

  • We almost gave up at one point but we had some spark of motivation after seeing the hologram in action
  • Working as a team and persevering to the end was very helpful
  • We managed our time efficiently and managed to sleep!

What we learned

  • Do a fresh install of Unity every time you do a hackathon
  • Don't use Unity, Unreal is better

What's next for HolAR

  • We want to try making the HolAR presentation more professional using glass rather than plastic
  • HolAR machine learning repository can be vastly expanded to create a very large database of 3-dimensional objects
