Recording a Video for an AI Hands and Wrists Assessment

Follow these guidelines for best results when recording a video of a worker performing a hand/wrist-intensive task for use in an AI Hands and Wrists Assessment.

Recording Guidelines

Camera Position

• • Position the camera so that both of the worker’s hands are clearly visible for as much of the work cycle as possible. Ensure the hands and forearms are not blocked by machines, tools, other body parts, or workstation fixtures.
  • When possible, keep the tool or object visible at the point of hand contact so it is easy to see how the worker holds, grips, and manipulates it.
  • Ideally, record from a front view. If that is not possible, use a side view. Avoid over-the-shoulder views whenever possible.

Camera Distance and Background

• • Position the camera close enough so that the hands and forearms fill a reasonable portion of the frame. Hands that appear small in the video are harder to analyze accurately. Aim for a distance where individual fingers and grip positions are distinguishable.
  • Only one worker should be visible during the work cycle. Avoid other workers’ hands or bodies in the background, as additional people in the frame can interfere with accurate detection.

Stable Camera and Good Lighting

Keep the camera as steady as possible throughout the recording. Make sure the work area is well lit and that there is enough contrast between the worker’s hands and the background or workstation, so that the hands are easy to see.

Use High-Resolution Video

Use a phone or camera that records high definition (HD) or better. Low-resolution videos make small hand movements and finger positions harder to analyze accurately.

Phones that typically support HD or higher-quality recording include the following.
