zMantra – User Guide

Welcome to zMantra

zMantra is a math learning app designed especially for visually impaired and blind learners. It uses spoken instructions, interactive input, and fun activities to make learning math easy and enjoyable.

Each screen includes spoken instructions and a Hint button located at the top-right corner. Tapping the Hint button opens a help page with detailed guidance on how to play that activity.

Accessibility and Interaction

When you open zMantra with TalkBack enabled, you will be asked to install and enable a custom accessibility service. This enhances gameplay in modes like tap, drawing, and touch.

In some game areas, TalkBack may not speak directly. However, the layout remains consistent and simple to remember:
- Top-left: Back button
- Top-right: Hint button
- Drawing mode only:
- Just above bottom-left: Reset button
- Just above bottom-right: Submit button
- The rest of the screen is for drawing input

In drawing mode, TalkBack is still available if you swipe near the bottom area of the screen.

When you open the app after the loading screen, you will hear the following menu options:
- Quick Play
- Learning Mode
- Game Mode
- User Guide
- Settings

Use swipe gestures or explore by touch to select an option.
