Abstract: Embodiments herein describe a video editor that can identify and track objects (e.g., products) in a video. The video editor identifies a particular object in one frame of the video and tracks the location of the object in the video. The video editor can update a position of an indicator that tracks the location of the object in the video. In addition, the video editor can identify an identification (ID) of the object which the editor can use to suggest annotations that provide additional information about the object. Once modified, the video is displayed on a user device, and when the viewer sees an object she can is interested in, she can pause the video which causes the indicator to appear. The user can select the indicator which prompts the user device to display the annotations corresponding to the object.

Abstract: Three-dimensional models (or avatars) may be defined based on imaging data captured from a customer. The avatars may be based on a virtual mannequin having one or more dimensions in common with the customer, a body template corresponding to the customer, or imaging data captured from the customer. The avatars are displayed on displays or in user interfaces and used for any purpose, such as to depict how clothing will appear or behave while being worn by a customer alone or with other clothing. Customers may drag-and-drop images of clothing onto the avatars. One or more of the avatars may be displayed on any display, such as a monitor or a virtual reality headset, which may depict the avatars in a static or dynamic mode. Images of avatars and clothing may be used to generate print catalogs depicting the appearance or behavior of the clothing while worn by the customer.

Abstract: An operating area for a virtual reality system may be defined based on the positions of sensors (e.g., infrared sensors) or fiducial markings within an environment where the virtual reality system is to be operated. The sensors or the fiducial markings may be provided on an operating surface in the form of a carpet, a mat or another like floor covering. When the virtual reality system is to be calibrated prior to use, positions of the sensors or the fiducial markings may be sensed by a base station, a headset or another virtual reality system unit, and an operating area may be defined based on virtual boundaries constructed using such positions.

Abstract: A video tagging system that can generate tags corresponding to associations of object-related keywords mentioned in a video to time instances in the video is described. The video tagging system identifies a particular object associated with a video. Using a transcription of audio content within the video, the video tagging system determines a keyword mentioned in the audio content that is associated with the object and a time instance within a timeline of the video when the keyword is mentioned. The video tagging system generates a tag that associates the keyword with the time instance and sends an indication of the tag to a user device. Once the video is displayed on the user device, the user can search for the keyword. This prompts the user device to display a marker indicating the time instance when the keyword is mentioned.
