As noted in the last log on this topic: we have no way to effectively tell the computer the meaning of our actions.
Many people who are new to gaming find the controls intimidating (they don't know how to speak the game's language.) But we humans are really good at using our fingers to manipulate stuff, so using hand input is right now the most natural way to interact with computers.
To be able to express emotions to the computer, you must be able to perform an action with a range of emotional modifiers. And this needs to happen in real time. So before we come to a temporary solution, let's review our most common input methods:
Traditionally the joystick has been used for movement and camera controls, but they have so much more potential. That is because they can blend between two values, let me explain:
If we assign actions to the Y-axis of the stick and modifiers to the X-axis of the stick, we are suddenly able to specify the meaning of our actions. This opens for new gaming experiences that revolves around character interactions.
And best of all, it is an easy concept for new gamers to pick up; "Don't worry about all the buttons, you'll only be using the two sticks."
