Vuforia Chalk: Remote Assistance Powered by Augmented Reality

Bring your technicians and multiple experts together for real-time problem-solving and collaboration

Communicate. Collaborate. Get it done.


Discover augmented reality-based remote assistance and quickly scale problem-solving guidance, support, and expertise to your factory operations and service teams. Vuforia Chalk combines advanced AR collaboration tools with real-time video communications to connect a field technician with an expert so that they can both see and discuss the situation at hand. Technicians and experts can draw digital annotations on a mobile screen or desktop that accurately stick to 3D physical objects in the real world, allowing the expert to guide the technician through a process, step-by-step.

AR collaboration tools that drive value, fast

Vuforia Chalk makes augmented reality widely available and quickly accessible. Leverage the devices already in your employees’ pockets to enable better remote assistance and accelerate AR’s time to value in your enterprise.

Simple and intuitive

Download the Vuforia Chalk mobile app from public app stores, or get started with the Chalk web app without installing or integrating any software. Make your first call the same day you download with minimal setup and training time.

Multi-expert sessions

Include up to five participants in a single Chalk session to resolve your frontline problems quickly, effectively, and remotely. Facilitate real-time collaboration across the enterprise by connecting multiple tiers of expert support over a shared view of the problem at hand.

Leading computer vision technology

Chalk marries Vuforia’s powerful computer vision and real-time audio/video into a single application, enabling experts and technicians to collaborate more effectively from remote locations. Bring together AR and “see-what-I-see” remote assistance to keep employees connected, even when they can’t be in the same place at the same time.

Digital annotations that stick

Vuforia Chalk’s 3D environment mapping allows annotations and on-screen markup to “stick” to objects in the physical world, even as your technicians move around in their environment. Enable better communication between users with precise, highly accurate annotations that demonstrate clear and effective instructions and procedural guidance.

Safe and secure information

Vuforia Chalk’s video, audio, and images are encrypted end-to-end and no content is ever saved or stored on a cloud or server. A leading software-as-a-service (SaaS) solution hosted and delivered by Amazon Web Services, Chalk also has attained SOC2 Type I attestation.
