Abstract: A user interface apparatus for performing input by image processing of an input image includes a unit for switching a mode for performing pointing and other modes on the basis of a result of the image processing of the input image. A user interface apparatus for performing input by image processing of an input image includes a unit for switching at least a cursor move mode, a select mode, and a double click mode on the basis of a result of the image processing of the input image. A user interface apparatus for performing input by image processing includes a unit for checking whether an object of image processing is in a proper range within which the image processing is possible, and a unit for presenting at least one of predetermined visual information and audio information, if it is determined that the object is outside the proper range.

Abstract: An apparatus having an input for inputting a plurality of line drawings indicating changed shapes of a stroke and a quantizer for quantizing corresponding strokes between the plural line drawings input by the input into unit vectors each having a predetermined length. A portion between the plural line drawings is interpolated by obtaining an interpolating vector for interpolating a portion between the corresponding unit vectors in accordance with an amount of change between the corresponding unit vectors of the plural line drawings obtained by the quantization performed by the quantizer.

Abstract: A method and an apparatus for generating information input which are capable of realizing a direct command type information input scheme by which the gesture or the motion can be inputted easily. The apparatus has a timing signal generation unit for generating a timing signal; a lighting unit for emitting a light whose intensity vary in time, according to the timing signal generated by the timing signal generation unit; and a reflected light extraction unit having a sensor array for detecting a reflected light from a target object resulting from the light emitted by the lighting unit, in synchronization with the timing signal generated by the timing signal generation unit, so as to obtain a spatial intensity distribution of the reflected light in a form of a reflected light image indicative of an information input related to the target object, in separation from an external light that is illuminating the target object.

Abstract: A virtual object display apparatus displays an object moved in three-dimensional virtual space. A key frame memory section previously stores move data of each part of the object by unit of action of the object's movement in three-dimensional virtual space. A swing calculation section calculates the change of a basis point of the object by unit of action according to the move data of each part of the object. A display position set section calculates the change of display position corresponding to the change of the basis point in three-dimensional virtual space by unit of action. A display section displays the object movement in three-dimensional virtual space according to the display position by unit of action.

Abstract: A virtual object display apparatus displays the action of an object at high speed. An environment information memory section stores environment information of a plurality of objects in a virtual space. A view information memory section stores view information of an extent of a view area of the virtual space. A visibility decision section determine whether each of the plurality of objects is visible in the view area in accordance with the environment information and the view information. An motion generation section generates motion for each of the objects in the virtual space in accordance with a decision result of the visibility decision section. A display section displays the motion of each of the objects generated by the action generation section.

Abstract: A display apparatus displays behavior of a human model in an environment model. In the apparatus, a memory stores environment model data, human model data and patrolling path data in the environment model. A display displays the behavior of the human model in the environment model and special part of the environment model. The behavior includes the human model walking along the patrolling path. The special part includes a simulation result corresponding to an user operation. A change section changes the behavior of the human model and the selected portion of the environment model through the display means according to the user designation.

Abstract: A manipulation target such as a lever or button is displayed in a three-dimensional virtual space using three-dimensional computer graphics. The positions of a thumb and an index finger are detected. A manipulation instruction is interpreted, using interpretation rules described on the basis of a relationship between the detected positions and the thumb and the index finger and the three-dimensional coordinates of a display device.
