The invention relates to a computer program product for a stylus-based user interface for computers. The invention is a process for separating a stylus-based application program from the procedures used to implement stylus-based, user driven error correction processes. This separation allows error correction procedures to be used by many applications, providing consistency in the user interface and saving application development costs through reuse of these procedures.

Stylus-input recognition correction manager

A method of, and apparatus for, running several applications concurrently on a processing system. Virtual terminals are created for running the applications. However, the virtual terminals perform as though the processing system were a single terminal system. In this way, any application written for a single terminal system can run in this multiple virtual terminal environment. For interaction with one of the several applications running on this system, the real physical resources of the system are reallocated to the virtual terminal running the selected application.

System concurrently running application programs and selectively routing

Method for controlling the echo of user-initiated actions taken through the input devices of a workstation in a distributed computational system providing application processing services at a site remote to the user. When application services are being used, an application protocol located proximate to the user separates user input actions which do not require application computational response but which do require registration in the system from those actions which initiate events requiring application program computational response. The application protocol buffers the non-computational actions, and invokes a local service to register the actions and to stimulate a user-discernible response. Other actions are forwarded by the protocol to the remote application process in the host computer. The invention reduces the response time to certain user-initiated actions by providing local response facilities, thereby eliminating a time-consuming communication with the remote application process.

Method and apparatus for application software control of echo response

If object identity is written into pixel locations of the refresh buffer portion of a raster-driven display as objects are drawn or amended, and if such object identity is used to index color maps and tree-linked lists of multiple object displays, then editing functions, such as correlation and echoing, color mixing, and selective erasure, at the display level can be invoked and executed with a minimum of reprocessing of the display list at the host level.
