Gesture Search on Your Android Device
Gesture Search is a free Android app from Google that is designed to make it easier for you to find files, contacts, and applications on your Android device. With Gesture Search installed on your Android device you can draw on your tablet or phone’s screen to go directly to a contact, app, or file. When you install the app you can specify which gestures are connected to which commands.
Gesture Search could be a good accessibility app to install on Android tablets that are being used in your classroom.
