+//

+//
+// 'W', 'S', 'A', 'D' - Move forward, back; strafe left/right.
+// F1 - No stereo, no distortion.
+// F2 - Stereo, no distortion.
+// F3 - Stereo and distortion.

+// Y - Up
+// Z - Back
+// X - Right

+// ***** OculusRoomTiny Description

+// This app renders a simple flat-shaded room allowing the user to move along the
+// floor and look around with an HMD, mouse, keyboard and gamepad.
+// By default, the application will start full-screen on Oculus Rift.
+//
+// The following keys work:
+//
+// 'W', 'S', 'A', 'D' - Move forward, back; strafe left/right.
+// F1 - No stereo, no distortion.
+// F2 - Stereo, no distortion.
+// F3 - Stereo and distortion.
+//

+// Y - Up
+// Z - Back
+// X - Right

+// This function will initialize OVR::DeviceManager and HMD,
+// creating SensorDevice and attaching it to SensorFusion.
