The present invention relates to a method and system for managing multi-user tools for a workspace on a touch screen. Workspaces are generated for use with the touch screen and one or more of identifiable pointers are associated with them. A global tool element having a plurality of controls is generated and displayed on the touch screen. When more than one pointer is associated with one of the workspaces, redundant controls are removed from the global tool element and a local tool element is created for each associated pointer. The local tool elements comprise at least the redundant controls.

System and method for managing multiuser tools

A method comprising obtaining a first location of a first pointer contact on an input surface; calculating a restricted area proximate the first location; processing the first pointer contact; and inhibit processing of a second location of a second pointer contact within the restricted area.

Method for detection and rejection of pointer contacts in interactive input systems

An interactive input system comprises an interactive surface; at least one proximity sensor in proximity with the interactive surface and generating output signifying user proximity to the interactive surface; and processing structure configured to process user input generated in response to user interaction with said interaction input system and output from the at least one proximity sensor, said processing structure controlling interactive input system operation based upon at least one of said user input and proximity sensor output.

Interactive input system and method

A pen tool for use with a machine vision interactive input system comprises an elongate body, a tip on the body and a variable reflector disposed on the body. The variable reflector comprises a reflecting portion and an attenuating portion configured to control the amount of illumination reflected by the reflecting portion.

Interactive input system and pen tool therefor

A pen tool for use with a machine vision interactive input system comprises an elongate body and a tip arrangement at one end of the body, an end surface of the body at least partially about the tip arrangement carrying light reflective material that is visible to at least one imaging assembly of the interactive input system when the pen tool is angled.

An interactive input system comprises at least one imaging device having a field of view looking into a region of interest. At least one radiation source emits radiation into the region of interest. A pliable bezel at least partially surrounds the region of interest. The pliable bezel has a reflective surface in the field of view of said at least one imaging device.

Interactive input system and bezel therefor
