Sony is working on a new robot technology that watches your gameplay and reacts to your emotions. It is a companion robot that is seemingly developed to help lonely gamers? And encourage them to play more games. According to the patent, data shows that when a player is being watched it boosts his/her motivation for playing the game. The patent describes the robot as a "joint viewing player." The robot will react to your emotions.
The inventor focused on the possibility of utilizing a robot as a joint viewing player who experiences sympathy with a user. For example, it is expected that the user's affinity with the robot is increased and motivation for playing a game is enhanced by the robot viewing the gameplay next to the user and being pleased or sad together with the user.
