A sequence of versions of the video file may be created in a similar manner, which are selectable via a video version stack.

Abstract: Method of dynamically assigning storage locations starts with the processor receiving a signal from a first client device associated with a first user. Processor stores a current location of the first client device in a historical database and determines whether a home location data associated with the first user matches the current location. In response to determining that the home location data associated with the first user does not match the current location, processor determines whether the first user has been associated with the current location at a greater frequency than the home location data based on the historical database. In response to determining that the first user has been associated with the current location at a greater frequency, processor updates the home location data associated with the first user to the current location. Other embodiments are described.

During use, a server receives an indication that an AR object has been activated and interacted with on a display of an AR camera device and, in response, sends a control signal to a correlated IoT device. Conversely, the server may receive a signal from an IoT device and, in response, present and control a correlated AR object on the display of the AR camera device.

Abstract: Eyewear having a speech to moving lips algorithm that receives and translates speech and utterances of a person viewed through the eyewear, and then displays an overlay of moving lips corresponding to the speech and utterances on a mask of the viewed person. A database having text to moving lips information is utilized to translate the speech and generate the moving lips in near-real time with little latency. This translation provides the deaf/hearing impaired users the ability to understand and communicate with the person viewed through the eyewear when they are wearing a mask. The translation may include automatic speech recognition (ASR) and natural language understanding (NLU) as a sound recognition engine.
