The hoop is not visible.

Possible Causes:

Difficulty judging distance in VR

At the beginning, patients may find it challenging to judge the distance between VR visuals and reality.

Solution:

• Turn off dichoptic mode initially to help the patient adjust to the virtual reality environment
• If difficulty persists, simplify the difficulty level or customize settings to maximize hoop size
• Once the patient is comfortable, remove the adjusted settings, turn on dichoptic mode, and proceed with dichoptic training

 Hands are outside the sensing area

Solution:

• Stand in the center of the sensing area, facing forward with correct posture
• Press the "Recenter" button
• Move both hands to eye level
• If hands are still not detected, repeat this procedure
