Abstract: In a computer system having a display and a keyboard, a computer readable medium includes instructions for invoking a message hook procedure based on a mouse message indicative of a mouse event. Instructions also provide for identifying at least one focus application that has a current keyboard focus and of converting the mouse message into a command for the focus application. The command is then sent to the focus application and the mouse message is prevented from being routed to any other applications. In one embodiment, the commands include the command to page forward or backward through pages of Internet documents. In other embodiments, instead of converting the mouse message into a command, the message hook procedure displays a graphical user interface based on the focus application and the mouse message. The graphical user interface includes one or more commands that the user may select.

Abstract: In a computer system having a display and a keyboard, a computer readable medium includes instructions for invoking a message hook procedure based on a mouse message indicative of a mouse event. Instructions also provide for identifying at least one focus application that has a current keyboard focus and of converting the mouse message into a command for the focus application. The command is then sent to the focus application and the mouse message is prevented from being routed to any other applications. In one embodiment, the commands include the command to page forward or backward through pages of Internet documents. In other embodiments, instead of converting the mouse message into a command, the message hook procedure displays a graphical user interface based on the focus application and the mouse message. The graphical user interface includes one or more commands that the user may select.

Abstract: An operator input device is configured to provide position information based on relative movement of the surface and the operator input device. The operator input device includes an image detector which is configured to detect an image on the surface and provide an image signal corresponding to the image detected. A controller is coupled to the image detector and is configured to receive the image signal and provide the position information based on a position of the image relative to the image detector.

Abstract: The specification describes a user security system for use in conjunction with an operator terminal such as a personal computer. The user security system utilizes an intelligent security token, commonly referred to as a Smart Card, for security-critical operations. A peripheral reader device provides communications between the Smart Card and the operator terminal. The Smart Card is programmed to signal the reader device prior to performing a security-critical operation and to wait for a counter-signal before performing any such security-critical operation. The reader device has a security key that is physically operable by a person. The reader device is configured to supply the counter-signal to the Smart Card only in response to operation of the security key, and to prevent the operator terminal from supplying the counter-signal.
