Embodiment Construction

[0020] Leaving messages on whiteboards is a widespread security issue. Security breaches caused by writing on whiteboards pose serious problems in commercial settings. For example, information about one vendor's proposal may be inadvertently disclosed to another vendor. There are some situations (eg in patent law) where there is no remedy for inadvertent disclosure.

[0021] Here, an interactive whiteboard (IWB) system (also referred to as electronic whiteboard) is disclosed. The system includes a projector (eg, a short-throw projector) that projects onto the display surface of the whiteboard. The board is equipped to detect handwriting, drawings and gestures using a pen-like stylus or fingers. The display surface and write / draw / gesture sensors are the user interface (UI) of the board.

[0022] In one embodiment, an interactive whiteboard (IWB) system (or other such interactive device) includes a network connection and sensors to detect when people approach. The IWB syste...

Abstract

The invention discloses a method and a device for automatically terminating an interactive device session. In one embodiment, the system includes a memory and a processor coupled to the memory for: logging out a user, deleting locally stored data created during a session, and linking one or more system hardware The component is placed in a reduced power consumption state based on occupancy sensor data indicating the presence or absence of one or more individuals proximate to the occupancy sensor, and activity information associated with the display surface.

Description

technical field [0001] Embodiments of the present invention relate to interactive devices such as interactive whiteboards, and more particularly to the process of automatically terminating sessions with interactive whiteboards and other devices. Background technique [0002] Occupancy sensors, also known as motion sensors or proximity detectors are used to detect whether a person approaches the sensor. Typical sensors utilize passive infrared (PIR) technology. These sensors detect infrared energy from moving objects. An example of such a sensor is the Z-axis motion (ZMOTION) detection module from Zilog Corporation of Milpitas, CA. Some sensors simply detect the presence of a person (or an object confused as a person). Other sensors might detect the distance to the person or provide other information about their location or direction of travel. Another type of sensor is an active infrared (IR) sensor with an emitter and receiver that detects reflections or interruptions o...
