Element G: Construction of a Testable Prototype

Physical Aspect: 1 Button

This is a to-scale clay model of the physical aspect of our project. It is 3x4x1.5 with a button whose diameter is 2.5. There are slots on either side of the button so that once it is actually created, students can attach it securely to their wheelchair or headrest. Once we actually make this button, it will be 3D printed using PLA filament which is durable, cost-efficient, and easy to use.

Game Play: Save the Dinosaur!

This is a to-scale cardboard model of an iPad. Students will be using an iPad to play the game on a website. The website will be using HTML coding language and it will be free for the students to use. The model shows the start screen of the game.

Button Base

• This will function as the base of the button

• It has 2 slots so on either side so that it can be fastened to a wheelchair or headrest

• The hole on the side is for the auxiliary cord

• The limit switch will be placed in the center of the Button Base

Button Ring

• This will be placed in between the Button Top Ring and the Button Top as a guide for clicking the limit switch

• It will be attached to the Button Base so that the button won't fall apart

• 3D print all parts of button

• Strip the aux cord

• Push aux cord through base hole and knot it

• Place heat shrink onto both ends of the wire

• Solder the aux wires to the limit switch

• Heat up the heat shrink using a lighter

• Super glue limit switch into the limit switch holder

• Place the top ring into the ring

• Super glue the ring to the base

• Snap top ring into the top

• Let dry for 10 minutes

• Plug button into device and test

1. Start with coding the home page

2. Add the title “Save the Dinosaur!” across the top of the screen

3. Add a dinosaur at the bottom left of the screen

4. Add a start button to the left side of the screen that goes to the game play screen

5. Start coding the game play screen

6. Add a dinosaur at the bottom middle of the screen

7. Add the score of 0 to the top right of the screen

8. Add an exit button to the top left of the screen that when pressed goes straight to the start screen

9. Add an asteroid to the top middle of the game play screen

10. Move the asteroid down 1/20th of the screen every 1 second

11. Code if the button is pressed then move the asteroid to the left of the screen and add confetti

12. After 2 seconds remove the asteroid and confetti from the screen and add 100 points to the score

13. Code if the dinosaur get to ¾ of the screen then go to the end screen

14. Go back to step 9 until the score reaches 500

15. Start code for the end screen

16. Add end score at the top middle of the screen

17. Show replay button that when pressed it goes back to the start page
