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.
Claims36
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.
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.
