In the operation of game, no matter PC game or TV game, their
input method is limited to the combination of direction keys and function keys.
For some specific game genre, their game command is quite complicate.
Additionally, for some fighting genre
software in
game console, the game command is performed via a
joystick which is designated to input very complicate key combination.
For example, when player want to make in-game virtual character performing special ability or skill, they have to use
joystick to input a consecutive key combination in seconds or in the situations, pressing several function buttons on
input device at the same time, such as →↓+A ┘ or ↓←↓→+ABCD, which is very difficult for a beginner.
Moreover, most game players play several video games at one time, and every game has its own command
list or hot key setting, thus it is very difficult for the player to memorize a large number of command order or key combination.
Hot keys are generally in a large number and incompatible for different games.
Therefore, it is inconvenient for the user to memorize and operate all hot keys corresponding to different games.
Summarily, current hot key
system for video game has some disadvantages: First, Most video game can not allow players customize or configure their own hot keys.
Player can only use the default hot keys predetermined by the game designer, which is sometimes inconvenient and uncomfortable to players because the hot keys corresponding to different computer-game operating actions are usually randomly disposed in different areas of the keyboard and player are not allowed to create or configure their own personal hot key
list for their frequently-performed action in game playing; Second, not all available video games supported or are provided with hot key feature, especially for most TV games, players usually input command via game controller (i.e. gamepad), which usually has no spare button for hot key specifying.
Though there are some sharewares and program such as Auto Hotkey in PC
system can allow users edit their hot key list and be applied to any PC games, they can not be installed on the
game console or non-PC game platform to be implemented to perform the hot key function.
Thus, the applicability of hot key is limited.
In addition, the operation of hot key in current gaming industry is limited to the key input, i.e. player will specify a key on the keyboard or a button on the controller as their hot key.
Though this conventional method is convenient and effective, it is insufficient in some situation.
For example, the number of button on game controller is less, there are no spared buttons for hot key use, and the hot keys player want to create are too many, it is not easy for players to memorize all hot key setting and their corresponding action.
