An input device for fighting game by measuring the force and movement of arm
Fighting video game uses joystick and buttons for various skills. Balancing is important aspect of fun. Some skill is big in damage and takes long time to make and requires complex input sequence. However for beginners this complex input sequence is barrier to enjoy games.
A new device for human computer interaction, Muscleman, is developed. This device acquires the surface Electromyogram of the superficial flexor muscle in the forearm, and the acceleration signal
of the forearm's movement. The device can classify hook and straight punch motions of the forearm by analyzing the acceleration data. By analyzing the Electromyogram signal, the force exerted by the user can be measured and used as input signal, even when there is no explicit movement of the forearm, as in the case of isometric muscle contraction.
By using this device the user can intuitively make various punching motions, such as a straight punch-like motion or upper cut-like motion. By using muscle contraction as an indication of force the user can intuitively make a special charged attack, such as fireball. Furthermore the muscle fatigue index can be measured and used to give feedback.
