Non-transitory computer readable medium, computer device, and method

A computer device that includes a vibration mechanism for generating vibration or that is wirelessly or wiredly connected to a vibration device having the vibration mechanism, the computer device configured to:

• calculate a movement vector indicating a movement direction of a moving object or a user's operation point when the moving object or the user's operation point moves on at least one surface of a virtual object;
• and
• generate vibration information for controlling an operation of the vibration mechanism, based on a normal vector of the at least one surface located on a movement path of the moving object or the user's operation point and the movement vector, when the moving object or the user's operation point moves along the movement path.

A method to be executed in a computer device having a vibration mechanism for generating vibration or in a computer device wirelessly or wiredly connected to a vibration device having the vibration mechanism, the method comprising:

• calculating a movement vector indicating a movement direction of a moving object or a user's operation point when the moving object or the user's operation point moves on at least one surface of a virtual object;
• and
• generating vibration information for controlling an operation of the vibration mechanism, based on a normal vector of the at least one surface located on a movement path of the moving object or the user's operation point and the movement vector, when the moving object or the user's operation point moves along the movement path.
