INTRODUCTION echnology is like weather which changes with the spinning globe. Most of these are designed to work in background without being known to the end user. However the general issue is    . Technology is of no use if it takes too much of load to meet the requirement. While things are getting cheaper and smaller, technologies have to be smart enough otherwise they will get diluted to other forms or they will simply vanish. Another issue is . What if the approach solves the problem but is not available to all the end users. Same type of problem can be solved by many technological approaches. In such a case, the main issue that matters is availability, which makes difference between a successful approach and others. First study describes how the use of simple hardware can change the way we see a classroom whiteboards today. The whole system costs approximately $30. We used a Wii Remote [1], an Infrared LED pen and a software to digitalize the teaching and learning experience. The Wii Remote is the primary controller for the Wii (pronounced : we) gaming console. This design allows users to control the game using physical gestures as well as traditional button presses [1]– [2].The calibration and mouse cursor emulation software Manuscript received November 9, 2010.

The basic functionality includes annotation, sharing the written material over a shared connection. Second study is in development stage. According to the thesis, an array of LEDs and LDRs emulates a touch responsive display. Most of these diodes are available everywhere in the electronics market. This system costs approximately $5. II. LOW COST INTERACTIVE WHITEBOARD     A traditional classroom struggles to adapt according to the demand of today’s educational needs. This may be due to lesser funds, but this is a disadvantage of the technology that to solve the problem, it requires so many resources that it becomes unaffordable. Table 1 shows the various IWBs available in the market. As per the Table 1, Whiteboards cannot be availed to low budgeted schools and colleges. If we compare the mentioned products with our IWB (explained in this paper), prices get reduced to1/4 th . This study presents an opportunity to every school and college to get equipped with the aids which simplifies the experiences of learning and teaching. Thus, the paper simplifies the technologies used today. Hardware on which this IWB relies, is commonly available. It includes a Wii remote, an Infrared LED pen and a Projector. The calibration and mouse cursor emulation software namely , is an open source software (source code and the binaries are not yet available on the internet) which is a light weight , cross platform application. It communicates with the Wii Remote to track the Infrared blobs. This data is then used to simulate the cursor.
