Provided are an information processing apparatus and a method, and in particular, an information processing apparatus and a method for employing a 3D model generated using 3D-CAD. When attribution information (a distance, an angle, the diameter of a hole, a dimensional tolerance, etc.) is added to a 3D model, as the amount of additional information is increased, it becomes difficult for the geometry of a 3D model and the attribution information to be seen on a display screen. The visual direction (the attribution allocation plane) is set for a generated 3D model, and attribution information is entered that is to be positioned on an attribution allocation plane. By designating the attribution allocation plane, the designated attribution information, together with the geometry of the 3D model, is displayed on the screen.

Information processing apparatus and information processing method

The present invention relates to information processing apparatus and methods and, more particularly, to information processing apparatus and methods making use of a 3D model (3D shape) prepared by 3D-CAD. For adding attribute information (distances, angles, hole diameters, dimensional tolerances, etc.) to the 3D model, it becomes harder to recognize the shape of the 3D model and the attribute information on a display screen with increase in the added information. Thus each visual axis direction (attribute arrangement plane) is set for the 3D model prepared and attribute information is inputted so as to be opposed to the attribute arrangement plane thus set. When the set attribute arrangement plane is then specified, the opposed attribute information, together with the shape of the 3D model set, is displayed on the display screen. Names of attribute arrangement planes are arranged so as to avoid overlap thereof on the display screen, thereby suppressing deterioration of visibility. Each attribute arrangement plane has a frame and the attribute information is placed within the frame.

Conventionally, in the process for inspecting a molded product, a measurement point indicating a portion to be measured is defined by using attribution information, such as a tolerance difference, and a measurement program is created, or a manual measurement instrument is employed to conduct the measurement. According to the invention, provided is an information processing apparatus supporting general measurement operations, including those for manual measurements, by using attribution information, such as a dimension and a dimensional tolerance, that is added to a CAD model generated by a CAD apparatus.

In a pen-input computer or the like, it is impossible to distinguish an input method and to execute a proper process according to the input method. A touch panel driver generates finger-input coordinate values for a display screen. A digitizer driver generates pen-input coordinate values for the display screen. A processor receives the coordinate values and additional information indicative of either the finger-input or the pen-input from a source discriminator, starts an inputting process according to the input method, and allows a virtual keyboard to be displayed onto the screen or allows a &ldquo;CHR input pad&rdquo; window to be opened.

Information processing apparatus and its method

An influence by a vibration which is transmitted in the air is reduced, thereby preventing an erroneous detection of coordinates or a deterioration in a detecting precision. An elastic resin sheet is arranged on a coordinates input surface side of a vibration transmission plate so as to have a gap between the resin sheet and the vibration transmission plate and is fixed by an adhesive layer. When coordinates are inputted by a vibrator pen, namely, when a vibration is inputted, the resin sheet is warped by a writing pressure of the vibrator pen and the resin sheet comes into contact with the vibration transmission plate. Therefore, the vibration applied by the vibrator pen is efficiently transmitted to the vibration transmission plate. On the other hand, a vibration transmitted from the air is reflected by the boundary on both surface sides of the resin sheet and by the surface of the vibration transmission plate by a difference between acoustic impedances, so that the vibration entering the vibration transmission plate is remarkably reduced.

An electrode unit includes a signal electrode and a ground electrode. The ground electrode is come into contact with the conductive surface so as to be electrically conductive thereto. The signal electrode is come into contact with the contact member so as to be electrically conductive to the electrode surface of the sensor through the contact member.

Coordinates input apparatus and sensor attaching structure and method

A coordinates input apparatus which detects vibration, inputted by a vibration-input pen, by a plurality of vibration sensors provided on a vibration-transmitting tablet, and derives coordinates of a vibration-input point based on vibration transmitting time on the vibration-transmitting tablet. The vibration-transmitting tablet comprises a glass substrate and two sheets of resinous film laminated on the glass substrate. The two sheets of resinous film are laminated on both surfaces of the glass substrate in an orientation such that the stretched directions of the resinous film differ for 90 degrees. By this, a vibration-transmitting tablet where sheets of protection film are laminated, and a coordinates input apparatus which minimizes the changes in vibration propagation velocity depending on the propagation directions, are realized.

Coordinate input apparatus, method of controlling same and computer-readable memory

In the coordinate detection of resistive film system, detection of the coordinates of simultaneously designated two points is made possible. On a touch panel composed of two conductive films, whether input is made in a point or simultaneously at two points is judged by a current monitor. Simultaneous inputs at two points decrease the apparent resistance of the conductive film, and can be detected by an increase in the current. If the input of a point is identified, the coordinate data of the input point are retained as latest coordinate data in a RAM. If simultaneous inputs at two points are identified, coordinate data are obtained from the coordinate data retained in the RAM and from the potentials in the x and y directions, obtained from two conductive films constituting a touch panel, through amplifiers, and are outputted, together with the coordinate data retained in the RAM, as the coordinate data of the two points.
