Front-projection interactive whiteboards Use a video clip projector in front of the whiteboard. A disadvantage of front-projection whiteboards would be that the presenter, standing in front of the monitor, have to increase his or her arm with or with no stylus to stay away from casting a shadow.
A Wii-based mostly IR method was invented by Johnny Chung Lee, PhD. in 2007. Lee claimed that the system "Helps make a technological know-how available to a Considerably broader proportion of the population" (Talking at TED, April 2008) by utilizing a standard Wii remote control as being a pointer as well as the IR digicam about the entrance on the remote control as monitoring unit sensing gentle from an IR light pen. Lee made quite a few video clips on YouTube about This technique to reveal its operability, overall flexibility, and simplicity of use, and stating its modest rate — one of the most reasonably priced part is the infrared LED of your pen.
Whenever a pointer, finger or marker disrupts the laser curtain, an X,Y position might be traced. This is probably the couple of optical systems that do not require a reflecting body in the perimeter of the projected spot to operate.
On the other hand, even with all those shortcomings, The present Variation of my application does integrate lots of the attributes you desire. These involve:
This technology enables whiteboards to become made from any resources, but needs a suitably adapted active dry-erase marker or stylus.
In Vital Phase 1 Science, there was improved development for ladies of all attainment levels and for common and large attaining boys.
An interactive projector IWB requires a CMOS digicam designed into the projector, so the projector produces the IWB picture, but will also detects the place of the Lively IR mild pen when it contacts the floor exactly where the impression is projected.
"In reduced-potential teams it could in fact sluggish the pace of full course learning as specific pupils took turns with the board."

Projector/Laser light curtain – A dual infrared laser system is positioned in the best Center region of a flat surface. The laser beam sweeps throughout the floor creating an invisible curtain. The projector, typically an extremely short throw projector) incorporates a built-in digicam with an infrared filter that scans the projected region.
In other scenarios, IWBs connect with on line shared annotation and drawing environments such as interactive vector based graphical Internet sites.
This know-how will allow whiteboards to be made of any material; with this system no dry-erase marker or stylus is necessary.
These generally contain a chance to produce Digital versions of paper flipcharts, pen and highlighter alternatives, And perhaps even virtual rulers, protractors, and compasses—devices that may be Employed in conventional classroom educating.
At the same time, There's proof of enhanced functionality gains with the usage of interactive whiteboards. The BECTA (UK) commissioned a analyze in the effect of Interactive Whiteboards more than a two-calendar year period of time.
Nearly all IWBs offered globally include a single of four kinds of interaction among the consumer as well as the articles projected to the whiteboard. These are definitely an infrared scan technology; a resistive, contact-dependent board; an electromagnetic pen and affiliated software package; check here and an ultrasonic pen.
