Abstract: A computer-implemented system is provided, including a network consisting of the Internet, PSTN, and CATV network. The network is connected to multiple users' client systems, and also to multiple service provider systems. Each user has a user profile stored in a User Preference Database, while each service provider has service parameters defining the type of its service stored in a Service Database, both of which are connected to the network. The system further includes a Gatekeeper Server, which establishes voice communication among the client systems and the service provider systems. In operation, upon receiving a user's request for service, the Gatekeeper Server identifies one or more service providers whose service parameters match the user's request for service and the user's profile. Upon the user's selection of one such service provider, the Gatekeeper server automatically selects and establishes a preferred mode of voice connection between the user and the selected service provider.

Abstract: A method for automatically converting an outline font character into a glyph-based font character using a set of predefined basic glyphs stored in a glyph database is provided. Each basic glyph is predefined as a program for rendering the basic glyph for output. Additionally, each basic glyph is associated with a glyph signature consisting of feature points, and script sentences that obtain key points and width values based on the feature points. According to the automatic font conversion method, first, an outline font character to be redefined is captured. Then, one glyph is selected from the captured character. Thereafter, feature points are identified along the outline of the selected glyph and stored in a glyph signature. Next, the glyph database is searched and a basic glyph that topographically matches the selected glyph is retrieved.

Abstract: A method for allowing a layman user to visually calibrate a user display is provided. First, a standard display model is predefined with (i) a standard display colorimetric transformation matrix, (ii) a standard display luminance response function, and (iii) three standard display human perception response (HPR) curves in dim, average, and bright environments, respectively. Second, a user display model is created, also including (i) a user display colorimetric transformation matrix, which is not fully defined, (ii) a user display luminance response function, which is also not fully defined, and (iii) a user display human perception response (HPR) curve in dim, average, or bright surrounding environment, as specified by the user. Third, the user display luminance response function is estimated. Fourth, the user display colorimetric transformation matrix is estimated. Finally, based on the above estimation, a lookup-table (LUT) is created for converting standard display signals to user display signals.

Abstract: A system, method, and computer-readable medium for generating a glyph-based outline font are provided, which allow for font communication between different devices having various (high and low) resolutions. A method selects a character for display on the output device. The character consists of one or more glyphs, and each glyph forming the character is predefined by key points, width values, feature points that have predefined spatial relationship to the key points and width values, and curve ratios prestored in a curve level table. Next, the method determines the resolution of an output device. Then, for each glyph forming the character, the method retrieves curve ratios from the prestored curve level table according to the determined resolution of the output device. Curve ratios are used to create curve segments, which form the outline of the selected glyph.

Abstract: A method and apparatus for producing a stroked-based font defined by a stroke representation displayable on high or low-resolution output device. The stroke representation includes defining a basic stroke with key points and width values as its primary parameters and feature points and curve ratios stored in a predefined curve level tree type data structure as its secondary parameters. Curve ratios are retrieved from the curve level table according to resolution level of the output device. Also, hinting information for certain key points provides for a better displayed stroke in low resolution space. Hinting information is activated according to predefined data associated with the curve level table. A CAD tool allows a font designer to easily select the parameters for the design of basic strokes and stroke shapes. The CAD tool presents a real-time display of sample characters at various bitmap sizes during font creation.
