Furniture Assembly using Augmented Reality Priti Pachpande Sujay Umesh 12/15/2017

Motivation Everyone loves decorating and furnishing their homes. In US the furniture is not delivered as a single unit(assembled) rather it is delivered in pieces. Assembling them without an expert is a herculean task. We had an idea of making a interactive Furniture assembly manual using Augmented Reality. We are inspired from Apple  “Furniture Assembly without manual”. This project was worth spending our time because we would solve real world problem which is faced by common people everyday.

What is AR? Augmented Reality Features: User interactive Detects and aligns the virtual/3D objects with each other. Shows user how the product will look when assembled in real environment. Demonstrates the product virtually to the user to confirm if it fits in room

Literature Survey Assembly is a tedious job but with AR we are trying to make it interactive. Furniture Assembly using AR is still in testing phase. Players like Facebook, Ikea and other similar companies are offering AR solutions for developers AR itself is a relatively new technology with endless possibilities. We have few industrial solutions but none of them are interactive, they are passive. We aimed to create interactive furniture assembly.

Design We concentrated on one item Understood how it could be assembled. Create 3D(Polymodels) models for all pieces required in Blender E.g. Table will have plank and 4 legs Each of leg will have position with respect to center of plank Then all legs will be placed on respective positions Added interaction by user

Implementation Created 3D models in Blender Created Image Target(Dollar Bill) in Vuforia Created scene in Unity All 3D models set with properties and behaviors in Unity Added AR kit by Vuforia Synchronized all project modules to behave as one cohesive unit Added Step buttons on virtual screen to make it interactive Tested multiple times Generated FurnitureAssembly.apk Deployed on Android phone.

Scenarios We started with table assembly this time Like every other assembly its not only forward directional User interaction feature allows to choose any step at any time This makes user possible to prioritize assembly Results will be in DEMO We could successfully assemble a table with this app

Tools used: Blender for 3D models Vuforia for AR kit Unity for environment and integration C# for user interaction and model behaviors

Getting Started With Unity We need to first get developer key for Vuforia. Once starting the project we need to use the developer key in unity. Create database to hold target image. Use target image to impose AR.

Polymodels :

Result :

Script to make the AR dynamic.

Future work As we had to learn many tools to make it happen we could concentrate on one item assembly only but in future definitely catalogues could be created. Assembly instructions could be directed through device’s speakers and text written on screen Models could be superimposed in better way We can also do AR without the Target Image.

Conclusion

THANK YOU!!!!
