Vuforia Chalk is the preferred solution when situations call for a quick response. It is a powerful collaboration app from PTC that empowers people to solve technical challenges faster and provides frontline technicians the instructions and guidance they need quickly, using the Vuforia Augmented Reality (AR) platform technology from PTC. Vuforia Chalk delivers a ground breaking communication experience that allows people in different locations to share a live view of the same environment. Each participant can then draw simple annotations appropriately called Chalk Marks. Unlike other video conferencing apps, what separates Vuforia Chalk is that these Chalk Marks appear anchored to objects and surfaces in the environment, as if drawn on the objects and surfaces themselves. Both expert and technician can accurately mark up live views to highlight details or guide multi-step solutions. Chalk Marks stick where drawn, reducing potentially costly mistakes.
