How does Desktop Presence work?
Desktop Presence is used by the Simple In/Out Desktop app to detect when you are at your computer and when you are not. The Desktop app will update your status when you are detected as being "active" and when you are detected as being "away."
Simple In/Out Desktop will use your keyboard and mouse input to detect whether you're active or away. If there is no keyboard or mouse input for approximately 10 minutes, the app will consider you as "away" and update your status accordingly. When you move your mouse or use your keyboard again, you will be considered as "active" and your status will be automatically updated.
Your status will also update your status when your computer sleeps and resumes, so if your computer sleeps after less than 10 minutes, your status will be updated more frequently.
