The VibrateController Class
I am currently working on another Windows Phone Application, where I needed a way to show the user that they had successfully performed a task and therefore unlocked another feature inside the application.
First idea was adding some sound, but somehow I was not happy with that. So I thought, why not let the phone vibrate?
It’s actually not that hard. The Windows Phone 7 SDK allows me to control the vibrate function easily.
In the namespace Microsoft.Devices there is a class defined with the name ‘VibrateController’.
The only code I need for that function is:
When the user clicks the particular button, the phone vibrates.
A few thoughts to keep in mind:
1. the shortest vibration / pause is 0.1 seconds.
2. the longest is 5 seconds, but that is not recommended.
3. 3 vibrations in one sequence are enough.
4. 0.2 / 0.3 are good choices for an alert.
Here you can find more information about the VibrateController Class.
