Being able to prototype ideas at low and high fidelities can be incredibly useful. Here are some of my projects that involve prototyping – both digitally and physically.

Lumi Light-Up Mouse

Lumi Light-Up Mouse


This project was from the Prototyping course at CCA taught by Graham Plumb. The goal was to design and prototype a mouse geared toward a specific audience. We would also use a NeoPixel light strip and Arduino to put inside the mouse and make it light up. I interviewed people and collected survey responses to generate a persona. I then used an iPad to digitally sketch out concepts for a mouse to suit their needs: something sleek and portable, but comfortable and fitted to their hand.

I used blocks of foam to sand down into the desired shape of my mouse. Yellow foam was used for the first 4 attempts, and pink foam was used for the final. I cut styrene and glued it to the foam mouse to create the look and feel of clickable buttons. I then spray painted this gray and filled in gaps and holes with Bondo.

I made a box out of cardboard and duct tape, glued my foam mouse to it, and I filled it with silicone. After this set, I removed my foam mouse, which left me with a silicone mold in the shape of the mouse. I poured resin into this to make the final version. Once I removed this from the mold, I used blue tape to mask out areas where I wanted light to shine through the mouse.

I attached my mouse to a stick and started to paint it using spray paint. The first layer was silver to prevent light from shining through. Since my mouse was intended to be two colors, I started by masking out the sides with tape and painting the rest of it white. This was determined based on the preferences of the people I interviewed, who wanted it to be white so they could tell when it needed to be cleaned! The final coat of paint was a light gray which went on the sides of the mouse to give the illusion of the texture being different – something with more grip to it.

The next-to-last step was photographing the work and showing the mouse with the light-up function working. Finally, I used my paper prototyping and visual design skills to design an out-of-the-box experience, with a multi-stage unboxing of the packaging design.
