Now with 6DOF (six degrees of freedom), BUDDY accurately mimics human movement – allowing for automated testing of headset performance including motion-to-photon latency, content stability, pose-drifting and world-locking. As the AR/VR market heats up, so does the competitive landscape. An early edge in the development process can mean all the difference. See BUDDY in action in our latest video:   **Optimize HMD Performance and Calibration with BUDDY** - Detailed analysis of HMD behavior through frame-by-frame image capture, synchronized with robot motion - Continuous AR/VR/MR performance measurement - Comprehensive, future-proof test system replaces complex lab setups - Compatible with custom content - Custom calculation capabilities - Achieves device and content quality analysis and device calibration - Streamlined integration with any existing test system - Solves AR/VR quality issues with precision robotics OptoFidelity offers industrial automation testing systems that allow AR/VR designers to gain end-to-end system performance visibility with a [‘shift-left’ approach](https://www.optofidelity.com/blog/using-industrial-automation-testing-to-increase-performance-excellence-and-output-of-hmds?hsLang=en). Incorporating automated testing into the early stages of HMD development can identify and alleviate potential challenges before they even appear. Early testing also helps to build a dataset after running realistic performance scenarios. ![Screenshot 2022-11-30 at 14.59.55](https://www.optofidelity.com/hs-fs/hubfs/01.%20Icons%20ad%20Logos/OptoFidelity%20logos/OptoFidelity%20Logo/Screenshot%202022-11-30%20at%2014.59.55.png?width=3584&height=2012&name=Screenshot%202022-11-30%20at%2014.59.55.png) Market-leading technology companies are betting big on the Metaverse. Central to this is the creation of HMDs that can show as realistic and comfortable of an augmented or virtual world as possible for its user. For manufacturers to achieve true immersion and presence optical quality and resolution is essential. Factors like image quality, tracking accuracy, and reliability all play a part in the consumer experience. OptoFidelity is leading the design and manufacture of automated test systems for AR/VR/MR market. BUDDY with its patented technologies has been serving customers since 2017. It is one of its kind in AR and VR HMD performance testing. BUDDY’s precision robotics accurately model human movement while gathering data on the tracking performance of AR/VR glasses. With its 6DOF (six degrees of freedom), BUDDY puts you ahead of the curve early in HMD product development.
