Collaboration system

摘要

A collaboration system provides enhanced user interface to enable users to interact with electronic devices. In one embodiment, users can add content to a digital system by using a pen that streams coordinates so that input to the digital system may be based on conventional pen and paper handwriting. In another embodiment, a pie-based menu system is used for input to large display area digital devices in which an occluded portion of the pie-based menu system is not used for direct input by the user. The selection of which areas of the pie-based menu system should be omitted from use is adaptive and responsive to whether the user is left-handed or right-handed, and the wrist angle defined by the user's posture. In still another embodiment, an ergonomic open-shaped pie menu system is provided to facilitate selection of options on a digital surface.

主权项

1. A collaboration system, comprising:
an electronic pen configured to enable a user to write on paper such that what the user is writing while using the electronic pen is visible on the paper, the electronic pen further being configured to record information about strokes made by the user while writing; and a collaboration server including a storage medium, the collaboration server configured to:
establish a collaboration session displayable on a digital surface;receive input from the electronic pen over a communication network and store the input from the electronic pen on the storage medium;process the input from the electronic pen to recreate what the user was writing while using the electronic pen; andcause the recreated writing to be shown during the collaboration session on the digital surface; wherein, in response to the user of the digital surface invoking a menu, the digital surface is configured to display the menu, wherein the menu is a pie-shaped menu having an input area, the input area extending in a circular segment extending less than 360 degrees such that no portion of the input area is disposed in an area expected to be occluded by the user's hand when the user interacts with the menu.
