UX Designer



Creating a bridge between Physical and Digital Interactions



  • 1 Week - Ideation
  • 1 Week - 3D Modeling + 3D Printing + Arduino [ CAD + Processing]
  • 1 Week - Fabrication 


The main purpose for the project was to learn 3D modeling and integrating an Arduino into a device. My main focus as an interaction designer was to bridge the gap between physical and digital interaction as much as I can.

Something that I valued highly when entering the field of HCI was the importance of physical interactions as much as digital. The UX field is still predominantly digital consisting of Apps and desktops. I wanted to create an interaction that incorporated the digital side as well as the physical to bring about emotions that people get from traditional interactions.

The form for the candle had two major considerations:

1. Digital Component housing space

2. Affordance of a candle through design

I wanted to maintain the feel of a traditional candle with the housing to replicate the experience of a candle but still have decent housing space for the Arduino Playground and the battery.

The first iteration of the 3D model was done in two pieces to make the construction with the digital parts easier. However, the joints with the thickness of the material prevented a sturdy product.

Learning from previous mistakes, I created the final model in one piece and removed the hole for the cable and decided to go with a battery pack that would really give the feeling of a candle and hide the digital aspect.

The main design choices I had to consider in the 2D modeling process was to make the battery pack and playground be easy to be placed in as well as allowing the switch of the battery pack to be accessible.
