Data replacement apparatus, computing device, and program for user and avatar coordination

A computing device configured to:

• acquire first control data having a value based on an actual position of a user's head and an actual position of a user's hand;
• determine whether an avatar of the user would assume a posture which falls outside of a predefined range of postures when the avatar is controlled according to the first control data;
• and
• replace the first control data with second control data, thereby causing the avatar to be controlled according to the second control data when it is determined that the avatar of the user would assume the posture which falls outside of the predefined range of postures,
• wherein the second control data comprises artificial position information which causes the avatar of the user to retain a posture within the predefined range of postures when the avatar is controlled according to the second control data, and
• wherein the artificial position information is determined by replacing at least one position component of the actual position of the user's head and/or hand with an artificial position component.

A non-transitory computer readable storage medium containing instructions executable by a processor of a computer which cause the computer to:

• acquire first control data having a value based on an actual position of a user's head and an actual position of a user's hand;
• determine whether or not an avatar of the user would assume a posture which falls outside of a predefined range of postures when the avatar is controlled according to the first control data;
• and
• replace the first control data with second control data, thereby causing the avatar to be controlled according to the second control data when it is determined that the avatar of the user would assume the posture which falls outside of the predefined range of postures,
• wherein the second control data comprises artificial position information which causes the avatar of the user to retain a posture within the predefined range of postures when the avatar is controlled according to the second control data, and
• wherein the artificial position information is determined by replacing at least one position component of the actual position of the user's head and/or hand with an artificial position component.
