This article discusses an exploratory sample we’ve created in the Mixed Reality Design Labs, a place where we share our learnings about and suggestions for mixed reality app development. Our design-related articles and code will evolve as we make new discoveries.
A progress control provides feedback to the user that a long-running operation is underway. It can mean that the user cannot interact with the app when the progress indicator is visible, and can also indicate how long the wait time might be, depending on the indicator used.
It is important to provide the user information about what is happening. In mixed reality users can be easily distracted by physical environment or objects if your app does not gives good visual feedback. For situations that take a few seconds, such when data is loading or a scene is updating, it is good idea to show a visual indicator. There are two options to show the user that an operation is underway – a Progress bar or a Progress ring.
A Progress bar shows the percentage completed of a task. It should be used during an operation whose duration is known (determinate), but it's progress should not block the user's interaction with the app.
A Progress ring only has an indeterminate state, and should be used when any further user interaction is blocked until the operation has completed.
You can add to your app's personality and brand identity by customizing the Progress control with your own custom 2D/3D objects.
