Accessible Uno

For my 3D Modeling and Prototyping class, we were tasked to create an accessible board game. Specifically for people who are visually impaired. The goal of the game was to be able to play it without needing to see any of the pieces involved and so we could do a game that previously exists.

The material that we used for this project was the online program Autodesk Fusion 360. We also used our understanding of Uno cards to help us create this project.

For this game, my partner and I started with creating the cards, she had three to make, and so did I. The basic set up for the card was 50mm x 80mm x 3mm so that there was still room to extrude as needed. For the edges, we rounded them with fillets that were 3mm, resembling the real uno cards. Dealing with the numbers and words in the middle is up to a lot of interpretation based on what you prefer. The oval in the center is actually an ellipse that was 65mm in length, for the rest of it, I just based it off of looks against the card.

To make our cards accessible for those who cannot see, we added braille lettering to say what the card was. We did this by creating little squares in the corners of the cards, and adding spheres to them in the position of the braille alphabet.

This can be done by creating a row of rectangular sketches, in a 4mm x 6mm format. Inside of these rectangles, you can place spheres with a 1.5mm diameter, which fits within the squares very nicely, in the braille format of 6 possible spheres, and they are filled to match with the letters.

When trying to figure out how the colors could be portrayed, my partner and I decided that the corners of the cards would be the easiest way to distinguish them. We made each of the colors correspond to a type of corner. I had the colors blue and green, which I made to be wavy for blue, which is the plus 2, and a tree like pattern for the green card for the green 7.

For both of the cards, I started off by cutting a hard corner as a base point. Starting with the blue, I moved the text so that it did not get cut off, and then I created a wavy line, and then negatively extruded the middle point that cut into the already existing card. Once finishing that, I extruded the other two sections so that they would become level with the rest of the card. I then repeated for the other diagonal corner.

For the green card, I started off the same, with the hard corner, but then it became a lot more unique. I added another sketch to one corner that resembled a tree. To do this, I used a circumscribed polygon function (which is found in the sketch section) and then made it have 10 sides. From there, I added a bunch of circles to make extruding easier, and lined them up with the outline of the polygon. Once this was finished, I used the trim function to get rid of all of the extra lines that appear in the sketch. Once this was finished, I extruded the polygon to line up with the rest of the card, and repeated for the diagonal corner.

To create these instructions, my partner and I followed the basic rules for Uno, which you can find paired with any Uno game. They resemble the instructions in the picture above.

Now the last thing that you have to do is have fun and play the game with some family or friends!
