Abstract: There is provided an information processing method to deal with the generation of inexact posture information. The information processing method includes acquiring posture information that indicates a posture of a moving body, extracting a feature amount from the posture information acquired at one time point or at multiple time points, determining whether or not the extracted feature amount is included within a definition range in a feature amount space, and acquiring, as a use feature amount, a feature amount that is included within the definition range, when the extracted feature amount is determined not to be included within the definition range, and generating data that indicates a posture or a motion, by using the use feature amount.

Abstract: A method of forming a colored pattern on the surface of aluminum or aluminum alloy comprising the steps of subjecting the surface to a first electrolytic treatment to form a background of anodic oxide film, and placing a pattern-forming electrode against the surface in adjacent but spaced apart relation. The surface is then subjected to a second electrolytic treatment to electrochemically impress the pattern onto the background by applying a voltage between the surface and the pattern-forming electrode in an electrolytic bath containing a metallic salt. The pattern-forming electrode is removed from the surface, and the surface having the background and the pattern is subjected to a third electrolytic treatment in an electrolytic bath containing a metallic salt to develop difference in color tones and intensities between the background and the pattern.
