2. An interactive whiteboard (IWB), is a large interactive
display that connects to a computer and projector. A
projector projects the computer's desktop onto the
board's surface where users control the computer using a
pen, finger or other device. The board is typically
mounted to a wall or floor stand.
They are used in a variety of settings, including classrooms
at all levels of education, in corporate board rooms and work
groups, in training rooms for professional sports coaching, in
broadcasting studios and more.

5. IWB may use one of several types of sensing
technology to track interaction on the screen
surface:
Resistive;
Electromagnetic;
Camera-based (optical).
Infrared optical;
Laser;
Ultra-sonic;
6. Resistive — Resistive touchscreens are composed of two flexible sheets coated with a
resistive material and separated by a microthin air gap. When contact is made to the
surface of the touchscreen, the two sheets are pressed together, registering the precise
location of the touch. This technology allows one to use a finger, a stylus, or any other
pointing device on the surface of the board.
Active Electromagnetic Board — These interactive whiteboards feature an array of
wires embedded behind the board surface interacts with a coil in the stylus tip to
determine the (X,Y) coordinate of the stylus. Styli are either active (require a battery
or wire back to the whiteboard) or passive (alter electrical signals produced by the
board, but contain no batteries or other power source). In other words, there are
magnetic sensors in the board that react and send a message back to the computer
when they are activated by a magnetic pen.
Passive Electromagnetic Board - In contrast to a active electromagnetic board this
one does not contain the sensing technology in the board itself, but in the pen. Tiny
magnetic fibers are embedded in the whiteboard and form a pattern that a
electromagnetic coil in the pen is able to sense. Therefore the pen is able to calculate
its location on the whiteboard ans sends this information to a computer.
Capacitive — Just like the electromagnetic type, the capacitive type works with an
array of wires behind the board. In this case however the wires interact with fingers
touching the screen. The interaction between the different wires (laminated in a
patented X- and Y-axis manner) and the tip of the finger is measured and calculated
to a (x, y) coordinate.
7. Infrared light curtain — When pressed to the whiteboard surface, the finger
or marker sees the infrared light. Software then manipulates the information to
triangulate the location of the marker or stylus. This technology allows
whiteboards to be made of any material; with this system no dry-erase marker
or stylus is needed.
Laser light curtain — An infrared laser is located in each upper corner of the
whiteboard. The laser beam sweeps across the whiteboard surface—much like a
lighthouse sweeps light across the ocean—by using a rotating mirror.
Reflectors on the stylus or marker reflect the laser beam back to the source and
the (X,Y) position can be triangulated. This technology may be combined with
a hard (usually ceramic on steel) surface, which has long life and erases cleanly.
Markers and styli are passive, but must have reflective tape to work.
Frustrated total internal reflection — Infrared light bounces within a
flexible and transparent surface. When the surface is deformed through a
finger press the internal reflection is disrupted and the light escapes the
surface where it is then sensed by cameras. Image processing software turns the
light spots observed by the cameras into mouse or pointer movements.
Camera Pen and Dot Pattern – These interactive whiteboards have a
microscopic dot pattern embedded in the writing surface. A wireless digital
pen contains an infrared camera that reads the dot pattern to determine the
exact location on the board. The digital pen uses this pattern to store the
handwriting and upload it to a computer. The accuracy is high since the
coordinates are usually fixed at about 600 dots per inch. With the electronics in
the pen, the whiteboard is passive (containing no electronics or wiring). This is
licensed as Anoto technology.
8. Ultrasonic only — These devices have two ultrasonic transmitters in two
corners and two receivers in the other two corners. The ultrasonic waves are
transmitted by the whiteboard surface. Some little marks in the whiteboard
borders create reflecting waves for each ultrasonic transmitter at different and
recognizable distances. Touching with a pen or even the finger in the
whiteboard causes these point waves to be suppressed, and the receivers
communicate the fact to the controller.
Hybrid Ultrasound and Infrared — When pressed to the whiteboard
surface, the marker or stylus sends out both an ultrasonic sound and an
infrared light. Two ultrasonic microphones receive the sound and measure the
difference in the sound's arrival time, and triangulate the location of the
marker or stylus. This technology allows whiteboards to be made of any
material, but requires a suitably adapted active dry-erase marker or stylus.
Wii Remote IWB — A Wii Remote is connected to a computer through its
Bluetooth connection capabilities. Using open-source software and an IR-Pen
(a pen made with a momentary switch, power source and an Infrared Led) any
surface (desk/floor/wall/whiteboard/LCD) can be turned into an Interactive
Whiteboard. The Wii Remote has a very accurate Infrared Light tracking
camera. Once calibrated, the Wii Remote detects a mouse click at the screen
location of the IR-Pen. The Wii remote was first adapted for use as an
interactive whiteboard by Johnny Chung Lee.
9. Answer the questions:
1. What is the most important factor of using
White board in the classroom?
2. What are three unique features of the Smart
Board technology?
-
-
-
11. Operating any software that is loaded onto the
connected PC, including web browsers and
proprietary software
Using software to capture notes written on a
whiteboard or whiteboard-like surface
Controlling the PC (click and drag), markup
(annotating a program or presentation) and
translating cursive writing to text (not all
whiteboards)
In some instances, the Interactive Whiteboard may
be provided with an integrated Audience Response
System so presenters can carry out polls and quizzes
and capture the feedback on the Interactive
Whiteboard
12.
13. Display information from the computer
Operate the software on the PC with a finger or a
special marker
Write, draw, erase, move a text, objects, graphics
Recognize written texts, and painted shapes
(rectangle, oval, circle, etc.)
Save page as a file, flipchart, and then retrieve them for
reuse
Add pictures, movies and sounds to the pages of
lesson’ flipchart
Use database of templates and create own templates.
