A brochure describing Vuforia Chalk, an easy to use tool, which combines advanced augmented reality (AR) with real-time communications to connect a field technician with an expert so that the expert can see and discuss the situation in the field. Technicians and experts can draw digital annotations on a mobile screen or desktop that accurately stick to 3D physical objects, allowing the expert to guide the technician through a process, step-by-step. With more accurate annotations, experts and technicians spend less time resolving issues, increasing operational productivity and efficiency.
