A computer system for managing presentation modification is configured to enable one or more users to request association of an author-created presentation with an account associated with the one or more users. In various embodiments, the system is configured to enable the author to make one or more modifications to the presentation. At least partially in response to modification by the presentation by the author, the system is configured to enable the one or more users to incorporate the one or more medications to the presentation associated with their account. In particular embodiments, the system is configured to store, in memory, each version of the presentation with various modifications and enable the one or more users to select any version of the presentation for presentation to at least one presentation viewer.
摘要:
A user interaction device, in particular an electronic pen, is disclosed which comprises an elongate outer casing (112) having an axis, a chassis (114) located within the outer casing, a switch having electrical contacts (130) supported by the chassis, and a nib (116) movable relative to the chassis (114) and serving to close the switch when axially displaced towards the chassis (114). In the invention, the nib (116) is attached to the chassis (114) by means of an axially compressible resilient element (144) of which a first end (142) is anchored to the chassis (114) and a second end (146) is anchored to the nib (116), and movement of the nib (116) in a direction transverse to the axis of the outer casing (112) is constrained by the resilient element (144).

摘要:
There is disclosed an interactive display system including a display surface, a first means for detecting a first type of user input at the display surface and a second means for detecting a second type of user input at the display surface, wherein at least one portion of the display surface is adapted to be selectively responsive to an input of a specific type.
摘要:
A computer system for creating and displaying a presentation is disclosed. The computer system may receive a request to generate multiple presentation slides and to associate the slides with a particular background. Later, during a presentation, the system simultaneously displays the slides against the one or more backgrounds within a slide display area. The system may be configured to allow one or more users, during the presentation, to: (1) selectively annotate the slides; (2) save the annotations to memory for future use; (3) independently rotate and/or resize one or more of the first and second slides; (4) remove the first slide from the slide display area independently of the second slide; and/or (5) add one or more additional slides to the slide display area.
