The Buddy Test System measures VR and AR headsets with up to six degrees of freedom.

optimum precisiona Finnish manufacturer of screen metering systems, has developed what is likely to be one of the most nightmare-fuelling test pads ever made,”owner. Attached to a jet black robotic platform (partial) Human head model with special vision unit Virtual reality headsets and augmented reality glasses.

With a headset placed on the model, two cameras in the artificial skull imitate the eyes. Advanced version of system handles Tests in all six degrees of freedom. Buddy’s best design to date is able to check many headphone parameters with complete freedom of movement.

Robot tests for AR and VR headsets

many axes Enable versatility testing system. The tire slides sideways on a floor rail, rotates around its axis, raising and lowering the “artificial head”. this is It imitates the free movements performed by real headphone users as well: forward/backward, up/down, left/right, nod, roll, and swerve (turn sideways).

The main areas of application are Development departments and production lines For VR and AR headsets. Examples include calibration, performance tests, and checking software content. In addition to image quality factors such as sharpness or color accuracy, tracking systems also find issues such as aberrations.

The manufacturer provides information on all VR headsets that are compatible with the test system. Optofidelity also describes the setup as Relatively uncomplicated. All necessary components are included. my friend, therefore, Replaces even complex laboratory equipmentAs per promotional material.

An important measure is the “latency from motion to photon”. Measures the delay between head movement and its visual execution in the virtual world. If the response time is too high, the background moves too late, which can lead to nausea or a reduced sense of presence.


It can also check how stable objects remain in the world or in front of the head. Thanks to the new synchronization technology, modern and futuristic screen technologies must also remain measurable. They include OLED, light field displays, and projection-based displays.

Three or six degrees of freedom

The datasheets on the official website have focused largely on previous iterations of the Three Degrees of Freedom (3DOF) buddy system. This restricted version only moves on a stable base, rather than sliding sideways on a rail across the floor.

The motion-to-image analysis described here can be performed at a frame rate of up to 120 Hz. The simulated pupillary distances range from 55 to 75 mm, which also simulates the narrow and very wide eye spaces.

The official Optofidelity Buddy website lists more technical details, including “Bot Specifications” for finer details such as movement speeds or potential deflections. There, the 3DOF variant can also be examined while performing a test with Hololens. Optofidelity provides rates for buddy systems upon request.
