This section will explore mediums users can use to convert their thoughts and actions (input) into the mixed-reality world.
As of the current version, there is a 3 Degree-of-Freedom hand-held controller as well as the 6 Degree-of-Freedom head position gaze.
You can use the phone as a 3 DoF controller that is essentially identical to the previously mentioned disk shaped 3 DoF controller. To make controlling even easier though, the phone utilizes its extra space for a few added swipe gestures.
Features
3 DoF (rotation) hand tracking
Suitable for most ray-based selection and manipulation, when the ray center does not need to be controlled by hand.
6 DoF head tracking-based ray center
You can translate and rotate the controller's ray center by moving your head.

Controlling with the position and direction that the user is facing. It is best to use gaze in coordination with controller methods to enhance user experience. However, on rare occasions where both of the user's hands are occupied, gaze can be used to provide a dependable way for targeting and selecting.

Feedbacks
Visual feedback
on areal attention - possible feedbacks include subject enlargement, coloration, and start of animation. This effect is created by including a "not looking" mode where the app is less pronounced when attention is not directed to it. Some apps can go to sleep when they leave attention for a given amount of time.
on enter - possible feedbacks include subject enlargement, change in color, animation from static, and bounding box.
on select - possible feedbacks include subject pulsates in size, brightness, and bounding box color.
on dwell select - display timer over vision center.
