Experiment Participation Information

Thank you for your interest in our hypotheses regarding the symmetry between vision and hands.

In this experiment, we will measure the ability to transmit information from vision to the brain and from the brain to the hands using a game. We will also verify the improvement in this ability through repeated trials.

The game involves controlling two hands, one with your left hand and the other with your right hand, to reach the goal on the stage. The hands can change their movement direction, jump, and run.

While the game is primitive, controlling two characters independently with separate hands may cause significant stress to participants. Please do not continue the experiment if you find it too stressful, and take breaks as needed.

* Features Included in the Game Used in the Experiment

• Top-down view action
