a mounting collar mounted to the base tube adjacent to and below the mounting bracket for rotation about the first vertical axis, the mounting collar substantially laterally enclosing at least a portion of the central portion of base tube and extending substantially to an undersurface of the mounting bracket;
a support arm having first and second ends, the first end connected to the mounting collar for rotation therewith about the first vertical axis, the support arm extending radially outward from the mounting collar along an undersurface of the mounting bracket and upward to the second end; and
a tablet member having a top surface, the tablet member mounted to the second end of the support arm with the top surface substantially horizontal.

CONTENT AMPLIFICATION SYSTEM AND METHOD

STEELCASE INC., Grand Ra...

1. A digital content conference sharing system for use with portable user computing devices capable of wireless communication, the sharing system comprising:at least a first large common emissive surface arranged for viewing by users within a conference space;
at least a first wireless communication subassembly for sensing portable device presence within at least first and second different sensing zones within the conference space and facilitating wireless communication with a portable device located within the first sensing zone and a portable device located within the second sensing zone;
a processor programmed to perform the steps of:
(i) when a portable computing device is detected within the first sensing zone, associating the portable computing device with the first sensing zone and enabling an interface for sharing content from the associated portable computing device on the common display screen; and
(ii) when a portable computing device is detected within the second sensing zone, associating the portable computing device with the second sensing zone and enabling an interface for sharing content from the associated portable computing device on the common display screen.

INFERRED ACTIVITY BASED CONFERENCE ENHANCEMENT METHOD AND SYSTEM

Steelcase Inc., Grand Ra...

1. A system for optimizing conference session activities within a conference space, the system comprising:at least a first camera having a field of view and generating images of at least a portion of the conference space within the field of view;
a processor linked to the camera for receiving images, the processor programmed to identify conferees within the received images, identify relative juxtapositions of the conferees within the conference space and to identify a conference paradigm based at least in part on at least one sensed session characteristic;
wherein the step of identifying a conference paradigm includes identifying at least one of first and second conference paradigms from a set of conference paradigms.
