Spatial keyframing for performance-driven animation

Abstract: This paper introduces spatial keyframing, a technique for performance-driven character animation. In traditional temporal keyframing, key poses are defined at specific points in time: i.e., we define a map from a set key times to the configuration space of the character and then extend this map to the entire timeline by interpolation. By contrast, in spatial keyframing key poses are defined at specific key positions in a 3D space where the character lives; the mapping from the 3D space to the configuration space is again defined by interpolation. The user controls a character by adjusting the position of a control cursor in the 3D space; the pose of the character is given as a blend of nearby key poses. The user thus can make expressive motion in real time and the resulting motion can be recorded and interpreted as an animation sequence. Although similar ideas are present in previous systems, our system is unique in that the designer can quickly design a new set of keyframes from scratch, and make an animation without motion capture data or special input devices. Our technique is especially useful for imaginary characters other than human figures because we do not rely on motion-capture data. We also introduce several applications of the basic idea and give examples showing the expressiveness of the approach.

Voice output device

Abstract: PROBLEM TO BE SOLVED: To provide a voice output device for smoothly and continuously outputting character strings in a plurality of languages by voice. SOLUTION: The voice output device comprises: a set language creating means for creating reading voice data of character string information in a set language; a storage means which stores the character string information in the set language, and which stores character string information in another language, and reading voice data of the character string information in another language in association with each other; a first output control means for outputting the reading of the character string information from the output means based on the voice data, when the voice data is stored in association with the character string information; and a second output control means for creating the voice data from the character string information, and outputting the reading of the character storing information from the output means based on the created voice data, when the voice data is not stored in association with the character string information.
