This is a version of tic-tac-toe that can be played by the visually impaired. The rules of the game are the same as classic tic-tac-toe but the board and pieces have been adapted in such a manner that it can be played without the use of vision. Instead of writing "x" or "o" to denote one's own mark on the board, pegs with spheres and cuboids on top of them are used instead, making them texturally distinguishable. The board is still a 3x3 grid but each spot is a hole that the pegs of the pieces fit into, which helps to notify a player that they have placed their piece. The board has a shallower groove that helps guide each player to available spots. There is braille on the side of the board that assigns "o" to the spherical piece and "x" to the cuboid piece. I created this to make a classic, fun game more available to those who may not be able to play it otherwise!

Supplies

This project was developed entirely in Autodesk Fusion 360: an online 3D design software.

Create the Board

Enter sketch mode and create a 150x150 millimeter square. Finish sketch and use the extrude tool to extrude the square up 50.8 millimeters.

Create the Peg Holes

Use the sketch tool to create 9 different 10x10 millimeter squares in a grid pattern, making sure they are each 20 millimeters from the edge of the board and 40 millimeters from each other. Extrude each square 45 millimeters deep into the board.

Create the Spherical Pieces

Using the sketch tool, create 8 rectangles that are 45x10 millimeters. Use the Extrude tool to extrude each rectangle back 10 millimeters. Next, select the form tab and add a quadball to the top of each rectangle with a diameter of 18 millimeters.

Create the Cuboid Pieces

Using the sketch tool, create 8 rectangles that are 45x10 millimeters. Using the line tool, add a 15x18 millimeter rectangle to the top of each existing rectangle. Using the trim tool, trim the line between the two rectangles, making them one sketch. Extrude these sketches back 10 millimeters.

Fillet the Board

Using the fillet tool, select each of the four edges on the top of the board and use a radius of 10 millimeters.

Create the Guidance Grooves

Using the sketch tool, create 12 40x10 millimeter rectangles connecting the peg holes. Using the extrude tool, extrude these rectangles 10 millimeters into the board.

Create the Piece Assignment Braille

Using the sketch took, create circles with a diameter of 2 millimeters on the side face of the piece in the formation of the desired letters and words. Use the line tool to split the circles in half, vertically and use the snip tool to delete the unwanted half. Use the revolve tool on each circle, selecting the straight edge of the semi-circle as the axis of revolution. Revolve each semi-circle 180 degrees.
