Hi
I am developing an application for the blind or visually community. I need to open the application based on a user trigger. I know there are features like push notifications that can be sent and once the user taps on it the application can open. But in that instance also the user would need to find his/her way to the push notification as the user would be a blind person. I was hoping to use like a shake or custom gesture without having the user to open the application. And this application needs to run in foreground as it opens the camera to describe items to the user.
I really value any suggestions,
Thank you,
Ishara
