Assignment 2: Form Making – Gaming Controller

Continuing from our previous assignment, we had to build a scale model of the chosen object design using blue foam. I’ve decided to choose the design inspired by the form of a crab as it’s visually and aesthetically appealing to me. Also, it brings an emotive aspect to the form as the navigation and movement features are strategically placed according to the placement of the eyes on the crab. In addition, I focused on the ergonomics of the gaming controller and refined the design to ensure it is comfortable for the usage.


The refinement process was on-going while I was creating the foam model to ensure the aesthetic and ergonomics is the best quality, given the time limitation. I had a few changes before I reached the final refinement form of the gaming controller (as seen below) and I was satisfied with the process. I’ve adjusted a few features and overall size of the form considering being able to create a better user experience for gamers.


The overall shape of my prototype is made out of blue foam and the features are made out of soft clay that hardens over time. 

After using the wire cutter to get the overall shape of my form, I did my first round of sanding however, I sanded the left side of the controller too much. To resolve the issue of asymmetry, I used epoxy to patch up the areas that have been sanded off too much.

To add the features of the gaming controller such as the navigation buttons and gamepad, I used soft clay to shape out the form of these features and let it harden over time. I did many rounds of sanding to achieve a smooth finishing but due to the color difference of the foam, epoxy and soft clay, I’ve decided to add two layers of wood putty and sand it once again. To add the grooves of the gaming controller, I used the automatic filer which has different sizes to create a small, thin indentation.

After the final round of sanding of the wall putty, I spray painted my prototype a glossy black and painted the features of the gaming controller. The last step was adding a matte varnish to give that cold and smooth finishing for my prototype. However, I felt like the varnish ruined the overall smooth finishing of my prototype and I should have stopped at spraypainting it black ): Lesson learned.




  • One of the challenges was being able to achieve a smooth finishing for an organic form like my prototype. Trying to sand the curves and the navigation buttons to achieve a rounded curve was tedious but I tried my best. In addition, I had to add epoxy due to over-sanding and I’ve learned to refer to the original sketch to ensure the dimensions is accurate to prevent such incident from happening again.
  • In addition, I wished I didn’t add the matte varnish as the finishing touch because it ruined the overall smooth and sleek finishing of my prototype.
  • It was a good experience trying to improve my model making skills and I’ve learned a lot of different techniques from the critique session with my peers.
