During play of a game, a user's performance is monitored. It is then determined if the player's performance is within a desired range of performance, and game parameters are adjusted if the user's performance is outside the desired range. In a multi-player game, parameters can be adjusted differently for each of the players to make the overall game play more competitive. ## Claims ### Claim 1 A method comprising: monitoring a user's performance while the user is playing a game by monitoring at least three-dimensional movements of a Human Interface Device (HID); determining, by a processor based apparatus and from monitoring the user's performance, if the user's performance is within a desired range of performance while the user is playing the game; and dynamically adjusting game parameters while the user is playing the game based on whether the user's performance is within or outside of the desired range of performance. ### Claim 2 (depends on 1) The method of claim 1, wherein dynamically adjusting game parameters comprises limiting game options available to the user. ### Claim 3 (depends on 1) The method of claim 1, wherein dynamically adjusting game parameters comprises enhancing game options available to the user. ### Claim 4 (depends on 1) The method of claim 1, wherein monitoring a user's performance comprises monitoring movements of a motion sensing input device being manipulated by the user. ### Claim 5 (depends on 1) The method of claim 1, wherein monitoring a user's performance comprises monitoring and evaluating the user's response with at least the HID to audio and/or visual stimuli. ### Claim 6 (depends on 1) The method of claim 1, further comprising receiving statistics about typical player interaction with the game and wherein the desired range of performance is obtained by using the receiving statistics about player interaction with the game. ### Claim 7 A storage medium storing a computer program executable by a processor based system, the computer program causing the processor based system to execute steps comprising: monitoring a user's performance while the user is playing a game by monitoring at least three-dimensional movements of a Human Interface Device (HID); determining if the user's performance is within a desired range of performance while the user is playing the game; and dynamically adjusting game parameters while the user is playing the game based on whether the user's performance is within or outside of the desired range. ### Claim 8 (depends on 7) The storage medium of claim 7, wherein monitoring a user's performance comprises monitoring movements of a motion sensing input device being manipulated by the user. ### Claim 9 (depends on 7) The storage medium of claim 7, further comprising receiving statistics about typical player interaction with the game and wherein the desired range of performance is obtained by using the receiving statistics about typical player interaction with the game. ### Claim 10 An apparatus for use with adjusting game parameters, comprising: at least a Human Interface Device (HID) for use by a user to interact with a game; and a processor based system configured to monitor the user's performance while the user is playing the game by monitoring at least three-dimensional movements of the HID, determine if the user's performance is within a desired range of performance while the user is playing the game, and dynamically adjust game parameters while the user is playing the game based on whether the user's performance is within or outside of the desired range. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein: the input device comprises a motion sensing controller; and the monitoring of the user's performance comprises monitoring movements of the motion sensing controller. ### Claim 12 (depends on 10) The apparatus of claim 10, wherein the processor based system is configured to receive statistics about typical player interaction with the game and the desired range of performance is obtained by using the received statistics about player interaction with the game.
