Abstract: Eyewear providing an interactive augmented reality experience by displaying virtual 3D content in a 3D frame on a display forming a field of view (FOV). The user can manipulate the displayed 3D frame using control components, such as touchpad of the eyewear device and the mobile device including control components. The 3D frame is displayed around the 3D content to avoid FOV clipping of the 3D content by the display which distracts from the virtual experience and draws attention to the device's limitations. The 3D frame is illustrated as a window positioned in a central portion of a virtual scene displayed on display. The 3D frame can be manipulated with reference to the virtual scene by the user using the control inputs, such as by rotating the 3D frame about a non-visual vertical axis within the virtual scene to create a seamless transition. Upon advancing the 3D frame to the next/previous frame having different 3D content, an event, such as playing animation, can be triggered.

Abstract: Methods and systems are disclosed for generating voice notes. In one embodiment, a messaging application implemented on a first participant computing device, receives a request to send a voice message to a second participant computing device in a communication session. In response to receiving the request, the messaging application selects a voice modification effect. The messaging application receives input to begin recording the voice message. While the voice message is being recorded, the messaging application receives speech input, modifies the speech input based on the voice modification effect in real time, and continuously updates an audio file with the modified speech input. In response to receiving input to terminate recording the voice message, the messaging application provides a first option to playback the audio file and a second option to send the audio file as the voice message to the second participant computing device.
