Game processing system, method of processing game, and storage medium storing program for processing game

1. A game processing system for processing a game having a first mode and a second mode, the system comprising one or more computer processors and one or more memory units for storing a mode switch condition for starting a mode switch from the first mode to the second mode, the one or more computer processors configured to:

provide, in the first mode, an interaction with a virtual character in accordance with first detection information obtained by an information processing device not mounted on a head of a player;

determine if the mode switch condition is satisfied in the first mode;

display a switch start object on the information processing device in the first mode upon determination that the mode switch condition is satisfied in accordance with a progress of the first mode;

commence a switch process from the first mode to the second mode upon selection of the switch start object; and

provide, in the second mode after the switch process, an interaction with the virtual character in accordance with second detection information obtained by a head mounted display mounted on the head of the player.

2. The game processing device of claim 1 , wherein the interaction with the virtual character in the first mode includes that the virtual character prompts the player to switch to the second mode.

3. The game processing device of claim 1 , wherein the interaction with the virtual character in the first mode includes an interaction for selecting settings in the second mode.

4. The game processing device of claim 1 , wherein the switch process is started in response to the interaction with the virtual character in the first mode.

5. The game processing device of claim 1 , wherein the switch process includes displaying, in response to the selection of the switch start object, a guidance for prompting the player to put on the head mounted display on the information processing device.

6. The game processing device of claim 1 , wherein the switch process includes switching to the second mode in response to selection of a switch object configured to be selected by the player gazing at the switch object.

7. The game processing system of claim 1 , wherein the one or more computer processors causes the information processing device to display a login screen to start the first mode after the second mode is terminated.

8. The game processing device of claim 1 , wherein the head mounted display includes an attachment to be fitted on the head of the player and the information processing device mounted on the attachment.

9. The game processing device of claim 1 , wherein, in the second mode, head tracking information for specifying a position and/or an orientation of the head of the player is calculated based on the second detection information, and

wherein the interaction with the virtual character is provided in accordance with the head tracking information.

10. The game processing system of claim 1 , wherein, in the second mode, the virtual character is displayed as a stereoscopic image, whereas, in the first mode, the virtual character is displayed as a non-stereoscopic image.

11. The game processing system of claim 1 , wherein the first mode is resumed when it is determined that the switch start object was not selected.

12. A method of processing a game having a first mode and a second mode with one or more computer processors executing computer readable instructions, the method comprising:

providing, in the first mode, an interaction with a virtual character in accordance with first detection information obtained by an information processing device not mounted on a head of a player;

determining if a mode switch condition for starting a mode switch from the first mode to the second mode is satisfied in the first mode;

displaying a switch start object on the information processing device in the first mode upon determination that the mode switch condition is satisfied in accordance with a progress of the first mode;

commencing a switch process from the first mode to the second mode upon selection of the switch start object; and

providing, in the second mode after the switch process, an interaction with the virtual character in accordance with second detection information obtained by a head mounted display mounted on the head of the player.

13. A non-transitory computer-readable storage medium storing a game processing program to be executed by one or more computer processors for processing a game having a first mode and a second mode, wherein the game processing program causes the one or more computer processors to:

provide, in the first mode, an interaction with a virtual character in accordance with first detection information obtained by an information processing device not mounted on a head of a player;

determine if a mode switch condition for starting a mode switch from the first mode to the second mode is satisfied in the first mode;

display a switch start object on the information processing device in the first mode upon determination that the mode switch condition is satisfied in accordance with a progress of the first mode;

commence a switch process from the first mode to the second mode upon selection of the switch start object; and

provide, in the second mode after the switch process, an interaction with the virtual character in accordance with second detection information obtained by a head mounted display mounted on the head of the player.
