Determination method, processing device, processing system, and storage medium

A determination method, comprising:

• causing a computer to
• display a virtual object in a virtual space,
• measure coordinates of a hand by hand tracking,
• perform a first determination of determining whether or not there is contact between the virtual object and the hand by comparing a distance between the virtual object and the coordinates of the hand to a threshold, and
• perform a second determination including
• determining whether or not there is contact between the virtual object and the hand when a first measurement result of a torque applied by a tool is received from a torque checker configured to measure the torque, and
• determining that the hand tracking is abnormal when there is no contact between the virtual object and the hand when the first measurement result is received.
