You can learn how to draw on a live screen with Vuforia Chalk.
Step 1: You can open the chalk on your phone.
The chat bubble icon has a line inside.It is usually found in the app drawer.If you're new to Chalk, there's a way to get started.
Step 2: Place or accept a call.
Both parties on a call can use their imaginations.The person sharing their screen must select the sharing option once the call is connected.
Step 3: To point the camera at the desired view, hold it.
A person will do this step when they share their screen.The other person on the call will see anything that comes into the camera's view.
Step 4: To draw, drag your finger on the screen.
Drawing on the screen highlights certain items in the view, such as buttons to press or adjustments to make.Anything you draw on the screen will show up on both users' screens.Since both users can draw on the same view, each user's lines will be different in color.The objects you drew on will remain over anything you draw.The person sharing their view can move the camera away without losing their markings.If you want to see the markings again, move the camera back to the original view.
Step 5: The current view can be frozen with the pause button.
The bottom-center part of the screen is where it is.It's helpful when you need to make more complicated markings.
Step 6: To remove the last marking, tap the undo button.
The curved arrow at the bottom-right corner of the screen can be removed if you make a mistake while drawing.
Step 7: When you're done, tap the phone receiver.
It is on the top of the screen.The screen sharing and voice call will not work together.
