A three-dimensional modeling system. The modeling system includes an antenna and a stylus. The stylus has at least one tag that communicates with the antenna to provide position signals of the tag, allowing the stylus to trace the surface of an object into a processor. The system may include more than one antenna, each producing an electromagnetic field within which the object to be modeled is positioned. The stylus may have two tags, which will allow derivation of orientation information from the position signals. The stylus may have a pressure-sensitive tip allowing the communication between the tag and the antenna to be controlled only when the stylus is in contact with the object to be modeled. The system may also have at least one tag attached to the object to provide more accurate information as to the position and orientation of the object relative to the points traced by the stylus. The stylus may also be used to trace an outline or other two-dimensional shape.

A graphical user interface in the form of a transparent keyboard may be positioned over an existing computer display. The user may input textual data through the keyboard by selecting keys in the transparent keyboard display. The text entry may then appear on the computer display in non-transparent or conventional format.

A transparent layer of display data may be provided over the top of another layer of display data on a display so that the user may see both layers clearly and simultaneously. This capability may be provided without employing modifications to the application program generating the data to be displayed transparently. That is, transparency effects may be provided for the display output data of application programs that do not have native transparency support. Embodiments of the present invention provide a generalized interface for accessing transparent display features by an application program. Creating transparent graphics for an application program lacking native transparency support includes selecting a virtual display to receive display data output from the application program, displaying non-transparent display data on a primary display, drawing the display data on the virtual display, and representing the display data from the virtual display transparently on the primary display along with the non-transparent display data.

Method of enabling display transparency for application programs without native transparency support

Providing input signals to a system having a display, the system being coupled to a source of video data signals, such as a video camera, is accomplished by analyzing the video data signals to detect an object in the scene over or at least partially coinciding with a location of at least one transparent user interface element, inserting at least one transparent user interface element into the captured video data signals, rendering the scene represented by the video data signals on the display such that the scene is transparently visible on the display, and generating an input signal for the system in response to detecting the object over or at least partially coinciding with the at least one transparent user interface element.

A method and apparatus for taking digital pictures. A film camera having a standard back panel, a shutter, and a primary lens is provided. An image sensing array is disposed within the camera in an area normally occupied by film so as to be in optical communication with the primary lens when the shutter is open. A read-out circuit is packaged to reside in a cavity normally occupied by film when the camera is employed to take standard pictures. The read-out circuit is coupled to the image sensing array and reads out an image captured by the image sensing array. A memory is coupled to a read-out circuit to store images read from the image sensing array. The memory is packaged to also reside in a cavity vacated in the absence of film. In one embodiment, the read-out circuit and the memory occupy the same cavity. In another embodiment, the read-out circuit and the memory occupy different cavities.

A method of creating transparent graphics for display in a computer system. A first frame buffer is provided to store display components to be displayed transparently on a computer monitor, the display components having a plurality of pixels. A second frame buffer is provided as a new output frame buffer. Pixels of the first frame buffer are color mixed with pixels of the computer system's original output frame buffer to produce color mixed pixels. The pixels of the output frame buffer are interleaved with the color mixed pixels, the interleaved pixels are stored in the second frame buffer, and the pixels of the second frame buffer are displayed. The color mixing is accomplished by a weighted average of the color components of the pixels of the first frame buffer and the output frame buffer. The interleaving is adjustable such that every second pixel, or every fourth pixel, or every eighth pixel, and so on, of the color mixed pixels is selected for inclusion in the second frame buffer, thereby changing the level of transparency of the displayed data.

A method for managing digital graphical data includes defining a first pixel using a characteristic in a first set of sub-pixels. A second pixel adjacent to the first pixel is defined using the characteristic in a second set of sub-pixels.

Providing input signals to a computer system having a display, the computer system being coupled to a video camera or other video source, is accomplished by capturing video data signals generated by the video camera, the video data signals representing a scene, rendering the scene on the display such that the scene is reflected and transparently visible on the display, analyzing the video data signals to detect an object in the scene, and generating an input signal for the computer system in response to the detected object.

Host input to a shared application is blocked while a guest has input control. Patch instructions are written over keyboard and mouse event procedures, which are operating system subroutines defining the normal entry points to the system queue for host mouse and keyboard events generated by host-mouse and keyboard drivers. The patch instructions call a patch subroutine which were written into the host-executed application-sharing program. The patch subroutine is operable to determine whether the host has control to enter the mouse and keyboard events into the system queue. If the host is without input control, the patch subroutine drops the events and replaces the patch instructions to their prior position on the keyboard or mouse event procedures. If the host has input rights, the original keyboard or mouse event code is written over the patch instruction and returned for execution. After execution, in which the keyboard or mouse event is deposited, the patch subroutine directs a replacement of the patch instruction over the keyboard or mouse event procedure. In a preferred embodiment, the host is able to take control at any time, to ensure execution of host events.

Association of a physical driver object with its logical contents in a logical driver object by identifying the logical driver object and using a non-operating system component to cause recreation of the physical driver object. A handle and a memory address of a logical driver object are obtained and the handle is locked to prevent its movement in memory. A clone of the logical driver object is created, whereupon the contents of the logical driver object and the contents of the clone are swapped. The clone is then deleted. Subsequent reselection of the logical driver object into a device context results in an observable recreation of a corresponding physical driver object.

A method and apparatus for synchronizing the display of the output of one or more applications being shared on participating host and guest computers, where the respective areas available for display of the output are unequal. In one embodiment, the host or a guest may alter the output display on the monitor's of all other guest participants. The host issues a command receivable by participating guests to alter the displayed output on the guest monitors corresponding to display output surrounding a point movable within the output display on the host monitor. A guest wishing to alter the output display on other guest monitors issues a request receivable by the host which in turn issues a command to all guests to update their output displays. The guests can be instructed to update the displays on their monitors to display output surrounding a point, movable under control of the requesting guest, within the output displayed on the requesting guest's monitor. In another embodiment, the output displayed on a guest monitor is updated automatically, as a shared cursor is moved from the boundary of the output displayed on the guest monitor.

Host translation of guest keyboard events is blocked to effectively isolate a guest keyboard from a host keyboard during applications sharing. A guest keyboard driver translates guest keyboard events which are transmitted to a host for use in shared applications. A patch instruction is written over a host keyboard event module which causes a jump to a patch subroutine when an attempt is made to deposit host keyboard events in the storage queue. Host keyboard events are marked by the patch subroutine and the marked host events are deposited in a shadow queue which is disposed in parallel with the host storage queue. Translated guest events also are deposited in the shadow queue. Raw host and guest keyboard events are stored in the host storage queue. When a shared application requires data from the host storage queue, a call for a translation of the outgoing data is made. In the event that the data is guest data, a second patch instruction on the module supervising the translation call causes a jump to a second patch subroutine, which bypasses the translation call and causes entry of the pretranslated guest event from the shadow queue into the shared application. If the outgoing event is a host event, the second patch instruction jumps to the second patch subroutine, which writes the translation instructions over the second patch so that the translating module can execute the translation. The translated host event then can be entered into the shared application. The second patch instruction is rewritten over the module supervising the translation.

Method and apparatus for using translated and raw guest keyboard input

Host multiple-byte character generator processing of guest keyboard events is blocked during applications sharing. A guest keyboard driver generates guest keyboard events which may be processed by any guest multiple-byte character generator. The guest events are transmitted to a host for use in shared applications. A patch instruction is written over a host storage queue which causes a jump to a patch subroutine when an attempt is made to deposit host keyboard events in the storage queue. Host keyboard events are marked by the patch subroutine and the marked host events are deposited in a shadow queue which is disposed in parallel with the host storage queue. Guest events also are deposited in the shadow queue. Untranslated host and single-byte character guest events, are stored in the host storage queue. When a shared application requires data from the host storage queue, the outgoing event is examined for origin, such as by examining the shadow queue. If the event is a guest event, a call is made to a host-executed applications sharing program, which in turn calls the host-multiple character generator. The call to the host multiple-byte character generator bypasses execution of the generator to preventing it from processing guest events prior to their entry into the shared application. In an embodiment of the invention, if the guest transmits a multiple-byte character to the host, the host-executed applications sharing system calls a host operating system module responsible for entering the guest multiple-byte character into a shared application. The guest multiple-byte character is entered into the shared application without a call being made to the host multiple-byte character generator.
