There are different types of projectors which are comprehensively covered in this article. In case you wondering what, interactive projectors are, these are ultra-short throw projectors with a video projection technology where a video is displayed onto a surface turning objects into interactive displays.
On the other hand, we will define interactive smartboards in two parts.
What is a smartboard? This is just like a whiteboard only that it has ability to respond to touch. Anytime the pc is projected to a smartboard it links up and displays pc screen on the board. The board needs to be calibrated for it to respond to touch or a stylus pen.
An interactive smartboard is therefore a smartboard that allows interaction with projected objects.
How an interactive projector works.
Interactive projectors are an improved version of the standard projector, in that some sensors have been added to track motion and add them to an image. This allows a presenter to access both the pc screen on the same surface where changes are being made. Not to mention that various people can engage.
Which technologies are used in interactive projectors?
The use two distinct technologies;
This makes use of a special camera different from projection lens, to trace the motions of a unique pen. Infrared/detector light is sent out to the camera when the pen comes into contact with projection area and the motion is recorded.
Digital Light Processing (DLP) technology.
DLP interactive projectors discharge a unique print into the image projected. This print is undetectable to the eyes as it flashes with a lightening speed through the screen.
Benefits of using interactive projectors.
- Environmentally friendly due to eradication of paperwork and printing.
- Improved productivity, students can listen without trying to take notes and can get the notes sent to them online.
- Professionals can make changes to their work before or during presentations to clients.
- Creates teamwork, work can be divided into groups and done on the screen simultaneously bringing students or staff together as a team.
- Quality presentations, smartboards allow them not only to switch through slides as was traditionally, but also add their thoughts to their work. Using images and any other they wish.
How does an interactive smartboard projector work?
Smartboard uses resistive technology, to mean there is a gap of air between sheets of resistive material in the smartboard. Once the board is pressed with a pen or finger, a contact point is marked and its coordinates match to the same spot on the screen.
Pressure on the board surface is enough for smartboard to perform functions of a special pen or mouse.
The user does not have to put a lot of pressure on the board for it to register contact, a moderately firm touch is sufficient.
Once a pen is removed from pen tray and color chosen, the pen tray notices the color selected and ink appears on the screen with that specific color. Pen tray senses everything that happens and responds accordingly removing eraser from the tray etc.
How strong is the smartboard surface?
Smartboard surface is made of a hard coat of polyester. Normal use can hardly cause any wear and tear to the surface, unless sharp instruments are used on the surface. In case of permanent markers staining the surface, special cleaning solvents can be used to clean the stains.
What kind of computer applications can be used with a smartboard?
- Point-and-click applications on a computer.
- Internet browsers
- Interactive CD-ROMs
- Word processing programs.
What are some of the school favorable applications that can be used with a smartboard?
- Hyper studio.
- Internet explorer.
How can a teacher use the interactive smartboard to engage a class grouped from 5-18yrs?
There are many projects/ideas that can be undertaken in a class ranging in that demographic, with the help of an interactive smartboard.
- Class demonstrations.
- Map reading.
- Students could create slideshows.
- Learning of computer skills and keyboard mastery.
- Art classes.
- Practice power-point presentations.
- Connect other devices to smartboard and watch documentaries etc.
Pre-school students all the way to campuses can highly benefit from using interactive smartboard projectors. It goes a long way to making education fun and effective.
Benefits of using interactive smartboard projector.
Smart boards improve the way students grasp information.
Smart boards are constantly gaining popularity for their ability to meet the various learning styles of students by providing visual aids, such as charts, videos, diagrams etc.
Smartboards give students a chance to engage on the screen, they can write, circle and highlight the contents of their lesson. Its more of a hearing and seeing type of learning where videos and pictures are available for better understanding.
Smartboards are simple to maintain.
They do not use mark pens which tend to stain so they have very low maintenance. Use of special pen and finger can hardly tamper with it.
They have access to knowledge databases.
Teachers can supplement to their lesson by gathering knowledge from other sources with the help of smartboards.
Students as well have access online resources to help with their projects.
Smart boards help to conserve the environment.
Use of smartboards has eliminated the need to print papers.
Teachers can share files to students via internet which reduces cost as well.

Similarities between interactive smartboards and interactive projectors.
- Both are used for the purpose of enhancing engagement and interactive-ness
Cost analysis of an average interactive projector.
Different companies price their projectors differently.
For example, below are some cheap projectors and their varying cost. The list combines both interactive and normal projectors.
And then, here we have some of the most expensive projectors. The list combines both interactive and normal projectors.
As you can see from the products above, the prices are very diverge. Some are very cheap and have limited features, while others are super expensive but with premium features.
The cost of a smartboard advanced model such as 55-inch smart kapp-IQ is around $4,000, larger models cost around $5,000 or more. Extra charges come from special smart pens, wall mounts etc.
It is important to note that interactive projectors have additional costs of lamp replacements and maintenance and this makes them more expensive in the long run though initially smartboards cost more.
Does a smartboard need a projector?
In case you are wondering whether its possible to use a smartboard without a projector, the answer is yes!!
The only precaution is that you have to use high quality dry erase markers or high odor dry-erase markers. These are unlikely to discolor the smart board.
Its also necessary to install smart board software to the pc to retain the notes you take on the whiteboard and use interactive features of the whiteboard without a projector.
There are few steps to do this;
- Link your pc to smart board and install necessary software updates.
- Click smartboard icon from your pc and choose control panel.
- Click radio button for “Non-Projected (whiteboard mode),” then click “ok “to allow smartboard to operate without a projector.
- Open the notebook software on your computer.
- Write on smartboard with dry-erase markers then erase with standard erase when done with notes.
