Creating and Designing Customized and Dynamic Game Interfaces Using Smartphones and Touchscreen

When playing a game, the user expects an easy and intuitive interaction. Current controllers are physical hardware components with a default number, size and position of buttons. While in some cases a game uses a few controllers buttons, in others it requires all buttons and even a combination of them. Besides that, the use of few buttons in a physical controller (i.e. controllers that can't change buttons position) may not lead to a great usability. This work extends a previous research, where we developed an adaptive control using a touchscreen device with machine learning techniques to gather input, rearrange the size and position from buttons. In this work we propose the concept of context sensitive adaptability, which can add, remove, change position or size of a button, depending of a game context. This is a new paradigm to game developers, so they can create a controller that fits to his game and adapts to pre-defined situations, e.g. an enemy approaching might be a reason to increase one buttons size, or a mini-game inside the game might change all the buttons for a moment. To use this concept, we developed a game to deal with the controller, adapting to game context.
