Abstract
The present invention relates to controlling a presentation device coupled to the presentation system using a user interface generated by a computing system, the user interface including one or more regions which vary in size based on whether the user interface is being displayed, the user interface accepting input from a pointing device to control the presentation device.
Claims37
A user interface for use in controlling a presentation generated by a presentation system, the presentation system comprising a computing system and a projection device, the projection device is capable of receiving input from a plurality of input sources including the computing system, the user interface comprising:
- at least one control region of the user interface, at least one presentation control operation being associated with the control region,
- wherein the user interface is modified based on a determination of which one of the plurality of input sources is providing an input signal to the projection device, and
- wherein other regions of the user interface are disabled in the user interface if it is determined that the one of the plurality of input sources is other than the computing system.
A method for use in a computing system for providing a user interface of a presentation system that includes the computing system and a projection device, the projection device capable of receiving video input from a plurality of input sources including the computing system, the method comprising:
- defining a user interface having at least one control region;
- determining which one of the plurality of input sources is providing an input signal to the projection device;
- and modifying the user interface based on the result of the determining step,
- wherein other regions of the user interface are disabled in the user interface if it is determined that the one of the plurality of input sources is other than the computing system.
A method for providing a user interface for use in controlling a presentation generated by a presentation system, the presentation system including a computing system and a projection device, the projection device is capable of receiving presentation data from a plurality of input sources including the computing system, the method comprising:
- generating at least one control region of the user interface, at least one presentation control operation being associated with the control region,
- wherein at least two or more of the plurality of input sources are separately connected to the projection device and the user interface is modified based on a determination of which one of the plurality of input sources is providing an input signal to the projection device.
An apparatus for providing a user interface for use in controlling a presentation generated by a presentation system, the presentation system comprising a computing system and a projection device, the projection device is capable of receiving presentation data from a plurality of input sources including the computing system, the apparatus comprising:
- a program memory to store process steps to generate at least one control region of the user interface, at least one presentation control operation being associated with the control region;
- and
- a processor for executing the process steps stored in said program memory,
- wherein at least two or more of the plurality of input sources are separately connected to the projection device and the user interface is modified based on a determination of which one of the plurality of input sources is providing an input signal to the projection device.
Computer-executable process steps stored on a computer readable medium, said computer-executable process steps for providing a user interface for use in controlling a presentation system, the presentation system including a computing system and a projection device, the projection device capable of receiving presentation data from a plurality of input sources including the computing system, said computer-executable process steps comprising:
- a step of generating at least one control region of the user interface, at least one presentation control operation being associated with the control region,
- wherein at least two or more of the plurality of input sources are separately connected to the projection device and the user interface is modified based on a determination of which one of the plurality of input sources is providing an input signal to the projection device.
