In this research, we examine the characteristics and possibilities of spherical displays by asking them to communicate while playing cooperative games using spherical displays. A user with a third person view and a user with a first per son view wearing a head mounted display (HMD) who share the same virtual space on the side of a spherical display communicate with each other through a cooperative game based on their respective viewpoints. we explore the possibilities of spherical display s by comparing them. Specifically, the player on the HMD side controls the character, and the player on the spherical display side looks at the character from a bird's eye view and gives hints to the HMD side player by conveying terrain information. Two gr oups of players are asked to play the game as subjects, their actions and conversations during the game are recorded, and a questionnaire survey is conducted to find out what kind of impressions they had on each other.
