Client brief

The client wants a prototype mobile app to be developed. The purpose of this mobile app is to support young children developing their mathematical skills. Specifically, the application needs to help children with converting measurements and units.

The application needs to be a game which asks the user multiple questions which need to - using numbers from 1 - 12. Both subtraction and division MUST NOT produce negative numbers.

There needs to be 10 questions in each game(level) and the application should keep track of the user’s score/s. There needs to be 3 levels; level 0 - no time limit; level 1 - has 20 second time limit; level 2 has a 10 second time limit; per question. 3 / 4

Finally, the application should include suitable graphics and sound that are engaging to young children.

Requirements for the application

Device capabilities

The device capabilities required for this application to utilise is minimal due to the simplicity of the purpose of the application. The capabilities that will be needed for this application to

work are:

● Speakers/audio output ● Touchscreen

NOTE: The accelerometer/gyroscope/magnetometer may be used to detect the

orientation of the phone - this depends on if the application will support both portrait and landscape displays.

Inputs

The inputs will all be done through using the touchscreen on the device - this will be used to press buttons that are seen in application.

Some of these inputs include but are not limited to.

● Level selection ● Country (to determine what units are local to the user) ● Answers to questions ● Replay level.● Next level ● Exit/close level ● Exit/close level ● Instructions
