Now it’s time for the second part of the “Royal battle”.
In one corner there is the long-established projector, in the other our upstart, the touch screen with integrated whiteboard software or connected Android Whiteboard Box. The previous result is 2: 2 or a draw for projectors and whiteboards in the areas of installation, image size and contrast and quality. You missed the first game? Here you can retrace the battle.
In order to detain you no longer: “Let’s get ready to rumble!”
Round 3: Interactivity
With digital whiteboards as well as with interactive beamers, professors, teachers or students can write directly onto the picture. In addition, both of them often provide sophisticated software for creating, displaying and storing teaching contributions, such as the Whiteboard software from InFocus. The difference shows when the screen is to be touched in order to select a program. Here, whiteboards work with digital pens as well as with the powerful multi-touch technology which allows you to write on the display with several fingers at the same time. In this regard, the projectors cannot match.
Round 4: Shadows
No matter how much you try to avoid, beamers cast shadows when people enter their projection field. And there are only a few things that are more disagreeable during a presentation than to be blinded by the light of the projector or not to be able to see a complete picture due to the shadows. Whiteboards create the image internally by using liquid crystal display panels. Thus, there is no shadowing. In addition, they are independent of light conditions and provide a clear picture even in strong sunlight.
Round 5: Costs
With regard to technology for the education sector, often the price is crucial. Projectors are the undefeated champions on the cost side. For example, a 65-inch JTouch is fast three times as expensive as a Short ThrowBeamer. Depending on the model, the Whiteboard software or Android Whiteboard Box has also to be added in the case of the JTouch. Although a lamp has to be bought and replaced every two years, the projectors remain cheaper.
After the judges have scored their points, a clear winner is determined:
However, the Beamers demand a rematch. The beamer technology is maturing and prices are falling. This point of the beamers might be lost this time. We will see. Notwithstanding the above: the ultimate winners of projection technology are neither whiteboards nor projectors, but teachers and students.Sharing, means caring:
