Modes of user interaction
A mixed reality (MR) device can allow a user to switch between input modes to allow interactions with a virtual environment via devices such as a six degrees of freedom (6DoF) handheld controller and a touchpad input device. A default input mode for interacting with virtual content may rely on the user's head pose, which may be difficult to use in selecting virtual objects that are far away in the virtual environment. Thus, the system may be configured to allow the user to use a 6DoF cursor, and a visual ray that extends from the handheld controller to the cursor, to enable precise targeting. Input via a touchpad input device (e.g., that allows three degrees of freedom movements) may also be used in conjunction with the 6DoF cursor.
