Input device for commanding control operations of a real and virtual object

A manually actuated input device for commanding machine- and / or computer-assisted control operations for kinematic motions of a real or virtual multipart object, including a force / moment sensor with which linear displacements in the form of translational movements in the direction of three axes (X, Y, Z), each standing perpendicular on the other, of a three-dimensional rectangular system of coordinates and / or rotational excursions in the form of rotational motions (A, B, C) about these three axes are sensed and converted into commanded motions of the object to be controlled is characterized by the commanded individual linear displacements and / or rotational excursions of the force / moment sensor being assigned specific kinematic motion patterns of parts of the real or virtual object thereby permitting manipulation or animation thereof as a transforming interlink and by the commanded velocities of the corresponding individual linear displacements and / or rotational excursions of the force / moment sensor being additionally weightable as a kinematic interlink assignment. The invention can be put to use e.g. in kinematic animation operations of human-like robots, figures or virtual animate beings.

Method for realizing virtual commercial transaction in game

Multiple shops exist in a virtual space of a game. Each shop belongs to any one of multiple unions. When a player character buys or sells a game item at any of the shops, a power point value of the union to which the shop belongs is increased according to the sales amount. The higher the power rank of the union to which the shop belongs becomes, the more the types of sellable and buyable game items are increased. The higher the power rank of the union to which the shop belongs becomes, the more cheaply the player can buy the game item and the higher the amount the player can sell the game item. The higher the power rank of the union where the shop belongs becomes, the more points that are given to a point card according to the buying or selling of the game items.

Digital and Analog Output Systems for Stringed Instruments

Systems are shown herein for use in stringed musical instruments for producing digital frequency and volume data. A finger contact sensor system detects the location of one or more fingers or objects at selected locations on a finger board of the instrument. Further string movement sensor systems determine if one or more strings are being played. A control system processes information from the finger contacting and string movement sensor systems to generate a digital signal containing the frequency data corresponding to the finger contacting point on the finger board and volume data corresponding to the sensed movement of a corresponding string.
