Provided is a controller arrangement for an optical sensing pen having a nib. The controller arrangement is configured to operatively sense location data by sensing location tags on a page of printed media, and to calculate a nib-to-tag distance indicative of the location data. The controller arrangement includes n infrared (IR) illumination LED and image sensor assembly configured to transmit IR light onto, and receive IR light reflected from, respectively, the page of printed media. The arrangement also includes a force sensing infrared LED and photodiode assembly configured to detect when the nib contacts the page so that the sensor assembly is only activated when the nib is in contact with said page. Also included are an infrared data association (IrDA) interface for short-range communication with a computing system and a processor arranged in signal communication with, and configured to control, the sensor assembly, the photodiode assembly, and IrDA interface to operatively calculate the nib-to-tag distance and to transmit related location data to the computing system. The arrangement also includes power management and orientation circuitry configured to deactivate the processor when the pen is sensed in a particular orientation for a predetermined period of time.

Surface acoustic waves are propagated in a lower-left oblique direction and a lower-right oblique direction from an excitation element located on the upper side of a non-piezoelectric substrate and then received by receiving elements located on the left side and the right side, while surface acoustic waves are propagated in an upper-left oblique direction and an upper-right oblique direction from an excitation element located on the lower side of the non-piezoelectric substrate and then received by the receiving elements located on the left side and the right side. Based on the received results at the two receiving elements, a position of an object in contact with the non-piezoelectric substrate is detected. The sensitivity in a region near the diagonal, which is influenced largely by propagation loss of the surface acoustic waves, is improved by increasing the widths of the electrode fingers of the excitation elements and/or the receiving elements, the number of pairs of the electrode fingers, or the aperture width of comb-like electrodes, according to an increase in the propagation distances of the surface acoustic waves, i.e., toward the region near the diagonal.

The invention relates to a coordinate detecting method for a touch panel. Firstly, a plurality of X-axis and Y-axis I/O ports are converted to a plurality of X-axis and Y-axis scanning wires respectively by orthogonal method. Polling signals are transmitted to X-axis I/O ports, and are transmitted to the X-axis scanning wires. According to the polling signals, a plurality of X-axis detection signals are stored. A largest X-axis detection signal and a second largest X-axis detection signal are determined by compared method so as to calculate a X coordinate position of the sensor pen touching the touch panel. The steps are repeated to calculate the Y coordinate position of the sensor pen touching on the touch panel. According to the coordinate detecting method of the invention, the number of the I/O ports can be reduced, and the resolution of the touch panel can be improved. For the calculation method, the invention utilizes simple compared method to obtain the largest detection signal and the second largest detection signal so as to calculate the coordinate position of the sensor pen touching on the touch panel. Therefore, the coordinate detecting method of the invention is very simple and rapid.

When a point on a tablet is designated by a marker, a recording indication signal is on, and recording of sound data is started. When the marker is released from the tablet, the recording indication signal is off, the recording of the sound data is finished, and coordinate data of the point and the sound data are linked. When information, such as characters, is inputted on the tablet using the marker, coordinate data based on the input and the sound data are linked through the coordinate data of the point. When the information such as characters is designated using a marker for playback, the sound data is played back.

In a stylus attachment structure for an IT product, the attachment structure formed on an IT product, such as, a laptop, a tablet PC and a PDA, comprises an attachment slot, a push-out member, a retaining member and an elastic part, wherein the push-out member is arranged in the attachment slot and the retaining member is slidably mounted at one end of the attachment slot for selectively retaining or releasing the stylus. In this way, when the stylus is not in use for a while, it can be obliquely plugged to one end of the attachment slot, it is easy for the user to pick up the stylus; alternatively, the stylus can be fully received in the attachment socket and further secured in place with a retaining member, thereby enabling the stylus to be attached properly so that it doesn't become loose.
摘要:
A method and system for enabling user interaction with computer software running in a computer system. The user is provided with an interface surface containing information relating to the computer software and including coded data indicative of at least one interactive element relating to the computer software. A sensing device in the form of an optically sensing stylus contains identifying data indicative of an identity of the user. When the user writes with the stylus, or uses it as a pointer, an operative end of the stylus is brought into contact with the interface surface. The sensing device senses indicating data indicative of the at least one interactive element using at least some of the coded data. The computer system receives the identifying data and the indicating data from the sensing device. The interactive element is identified in the computer system using the indicating data, and user data is identified using the identifying data. The computer software is operated at least partly in reliance on the user data, and in accordance with instructions associated with the at least one interactive element.

An information processing apparatus detects the sampling rate of a coordinate input device, and standardizes the writing data which is input from the coordinate input device based on the detected sampling rate. The standardized writing data is further used for signature verification or for handwritten character recognition. The information processing apparatus provides precise signature verification or handwritten character recognition even if signatures or handwritten characters for handwritten character recognition are input using digitizers having different processing rates.
摘要:
A sensing device for sensing a position relative to a surface. The surface has printed therein or thereon coded data including at least one data portion, and visible information, at least some of the coded data being coincident with the visible information. The sensing device includes a sensor for sensing at least one data portion when placed in an operative position relative to the at least one region and generating indicating data using the sensed data portion. The indicating data is indicative of a position of the data portion relative to the surface and an orientation of the sensing device relative to the data portion. The indicating data is then communicated to a computer system to allow the position of the sensing device relative to the surface to be determined.
