Abstract: A method for receiving input, by a virtual reality system includes creating a three-dimensional (3D) mesh for a virtual space. The 3D mesh includes a virtual keyboard, where the keyboard object comprises a plurality of virtual keys, a collision object corresponding to each of the plurality of virtual keys, and a cursor. The virtual reality system displays the 3D mesh on a head-mounted display (HMD), receives user input for moving a location of the cursor in the virtual space, and receives user input for selecting the collision object of one of the plurality of virtual keys based on the location of the cursor.

Abstract: A method for initializing a panoramic video by a graphical user interface (GUI) includes receiving a panoramic video, creating a three-dimensional mesh, and displaying a preview rendered from the three-dimensional mesh. The GUI displays a time selection interface and selects a frame time in the panoramic video with the time selection interface. The GUI displays a view selection interface and selects view parameters that define a camera orientation at the frame time of the panoramic video with the view selection interface. The GUI determines a selected frame of the panoramic video defined by the frame time and the view parameter, renders the thumbnail from the three-dimensional mesh based on the selected frame, and stores orientation data including the frame time and the view parameters.
