Abstract: Methods, systems, and computer readable media for receiving user input. According to one example method for receiving user input, the method includes identifying gestures from directional movements of a user's fingers on a touch sensor, mapping the gestures to alphanumeric characters, and outputting alphanumeric characters, including defining a set of the gestures as different sequences of at least two of: a contact event, a no contact event, a hold event, a finger movement in a first direction, a finger movement in a second direction.

Abstract: Apparatus and methods are disclosed for a virtual locomotion controller user interface and system that combines data obtained from various sensor devices to allow users to control the movements of their representation in a virtual world using sensorimotor responses closely resembling the tasks and actions they would physically perform in the real world. As a result, users can specify an avatar's locomotion style by assuming body postures normally associated with that type of movement, while controlling locomotion speed or displacement through foot forces and/or stepping motions and locomotion direction through foot and body orientation.

Abstract: A method and apparatus for interactively controlling and coordinating the limb movements of computer-generated articulated characters with an arbitrary number of joints. On-line computational methods are used for animating limb movements of articulated characters by solving associated forward and inverse kinematics problems in real time subject to multiple goals and constraints. The methods provide computer animated characters with fully interactive goal-directed behaviors, such as bipedal walking, through simultaneous satisfaction of position, alignment, posture, balance, obstacle avoidance, and joint limitation constraints. Goal-based motion primitives, called synergies, coordinate sets of joint movements which separately attempt to satisfy each of the above constraints.

Abstract: Recorded motion data is combined with interactive control techniques to manipulate the animation of articulated figures. The methods enable computer animated characters to produce fully interactive goal-directed behaviors, such as bipedal walking, through simultaneous satisfaction of position, alignment, posture, balance, obstacle avoidance, and joint limitation constraints while retaining qualitative characteristics of the original non-interactive motion data. Goal-based motion primitives, called synergies, are used to coordinate sets of joint movements that attempt to satisfy each of the above constraints.

The methods fully interactive goal-directed behaviors, such as bipedal walking, through simultaneous satisfaction of position, alignment, posture, balance, obstacle avoidance, and joint limitation constraints. Goal-based motion primitives, called synergies, coordinate sets of joint movements which separately attempt to satisfy each of the above constraints. The present methods adapt character movements on-line to accommodate uneven terrain, body modifications, or changes in the environment by automatically transforming and producing joint rotations relative to the instantaneous point of contact of the body with the world.
