Wearable multimedia device and cloud computing platform with laser projection system

Systems, methods, devices and non-transitory, computer-readable storage mediums are disclosed for a wearable multimedia device and cloud computing platform with an application ecosystem for processing multimedia data captured by the wearable multimedia device. In an embodiment, a body-worn apparatus comprises: a camera; a depth sensor; a laser projection system; one or more processors; memory storing instructions that when executed by the one or more processors, cause the one or more processors to perform operations comprising: capturing, using the camera, a set of digital images; identifying an object in the set of digital images; capturing, using the depth sensor, depth data; identifying a gesture of a user wearing the apparatus in the depth data; associating the object with the gesture; obtaining data associated with the object; and projecting, using the laser projection system, a laser projection of the data on a surface.
