ARitmetic

PHOTO / VIDEO BEING ADDED LATER!

ARitmetic is an AR mobile application that allows students to learn mathematics in a card game-type fashion. At each level, students are given a number they must make with a certain number of cards, manipulating them to make a maths equation to get the desired result. It was developed as a team project, where the other team members focused primarily on the non-programming side of the project. This was due to various factors, but mainly the short timeframe given and not wanting to have multiple versions of the same application. They primarily did the reporting and asset creation, which was of great help.

Here are the basic features I implemented and tasks I had done in this project...

• Detection to String: Created a system for identifying the cards detected through Vuforia and the phone. It worked by grouping the cards in a certain radius together and then translating the objects into a string in the left-to-right order.
• Maths Calculations:  Converted the string from the previous point into the proper maths equation, calculating everything from Addition, Subtraction, Multiplication, and Division in BODMAS order.
• Database Management: Uploading the cards to Vuforia, finding the right identifying points and ratio for each card to allow the phone to recognise it while not mistaking it as another card.
• User Testing: I did a whole lot of user testing to fine-tune the application into the best it could be given the short timeframe.
