Check out this cool companion app for the HTC Vive VR Headset. It's designed to help you avoid missing out on phone notifications and reminders when you are engrossed in a VR world. Here's a description and link from (and to) the Google Play Store:
"Don't miss what's important IRL while you're in VR. To get essential notifications in the world of virtual reality, just connect your phone with your HTC Vive. Notifications about phone calls, text messages and calendar events pop up without interrupting play and appear in the Vive tab on your System Dashboard so you can view them later too.
From the Vive tab on your System Dashboard, you can:
- Respond to a missed call
- Read text messages, send quick replies or call the sender back
- Get notified about calendar events and view the details"
