About this app

PetaNetra is an application that uses Augmented Reality (AR) technology to help blind people navigate independently in indoor public spaces to be more comfortable and independent. This application supports the use of VoiceOver to help convey information to the blind.

PetaNetra can detect your location and will guide you to the destination you choose. In using the application itself, there are 4 types of markers that will be found:

1. Place

2. Warning

3. Obstacles

4. Action

This marker functions to instruct users to take a certain action according to instructions. Examples of instructions that will be found in the application are “push the door”, “raise your hand to check your body temperature”, etc.
